The handle portion 111 and the first accommodating portion 112 are disposed on the same side of the second accommodating portion 113, and the extending direction of the handle portion 111 and the extending direction of the first accommodating portion 112 are substantially parallel. Specifically, the handle portion 111 is for the user to hold, and is also provided at one end of the second accommodating portion 113. The first accommodating portion 112 is used for accommodating a circuit board therein, the first accommodating portion 112 is disposed at a substantially middle portion of the second accommodating portion 113, and a coupling portion (not shown) for coupling the battery pack 13 is further disposed at an end of the first accommodating portion 112 away from the second accommodating portion 113. The second accommodating portion 113 is for accommodating the motor 14, the transmission mechanism 15, and the like.
The switch 12 may be mounted on the handle part 111 near the second receiving part 113 so that a user can relatively conveniently trigger the switch 12 when holding the handle part 111, and the switch 12 may be a main switch for starting the motor 14.
The battery pack 13 is used to provide a power source for the electric hammer 100, and the battery pack 13 is detachably coupled to the first receiving portion 112.
The motor 14 is disposed in the second accommodating portion 113, and the motor 14 is configured to convert the electric energy provided by the battery pack 13 into power and output the power to the transmission mechanism 15. A transmission 15 is provided between the motor 14 and the chuck 16 for transmitting the power output from the motor 14 to an accessory such as a drill bit or a chisel bit.
The chuck 16 is used to detachably attach a drill bit, chisel head, or the like to the electric hammer 100.
The secondary handle 17 is used for the user to hold the other hand when holding the handle portion 111 in one hand, so that the two hands respectively hold the front and rear positions of the electric hammer 100, the gravity center of the electric hammer 100 is approximately located between the two hands, and the holding stability is improved.
As shown in fig. 2 and 3, the electric hammer 100 further includes: a clutch device 18; the motor 14 includes: a motor shaft 141; the transmission mechanism 15 includes: a central shaft 19, a rocker bearing 21, a transmission wheel 22, a first transmission piece 23, a second transmission piece 24, a rotating assembly 25 and an impact assembly 26. Wherein, the clutch device 18 is used for realizing the switching of the transmission mode of the transmission mechanism 15, the rotating component 25 is used for enabling the electric hammer 100 to output the rotating force, and the impact component 26 is used for enabling the electric hammer 100 to output the impact force.
The motor shaft 141 is rotatable about a motor axis, and the motor shaft 141 is formed with or fixedly connected to an output gear 141 a. The output gear 141a is used to output the power of the motor 14 to the center shaft 19.
The central shaft 19 extends substantially in a direction parallel to the central axis of the motor axis, and an input gear 191 is further formed or fixedly connected to an end of the central shaft 19 near the motor shaft 141. The input gear 191 can be engaged with the output gear 141a of the motor shaft 141 such that when the motor 14 is started, the motor shaft 141 rotates about its motor axis, and the output gear 141a is engaged with the input gear 191, thereby driving the central shaft 19 to rotate about the central axis.
The swing rod bearing 21 includes: a wobble plate 211 and a wobble lever 212. Wherein the swing plate 211 is mounted to the central shaft 19 and is rotatable relative to the central shaft 19, and the swing lever 212 is connected to the impact assembly 26. When the swing disc 211 of the swing rod bearing 21 rotates, the swing rod 212 drives the impact assembly 26 to reciprocate, so that power is output to accessories such as a drill bit and a chisel head, the accessories such as the drill bit and the chisel head are driven to impact a workpiece, and the function of chiseling of the electric hammer 100 is realized.
The transmission wheel 22 and the rotating assembly 25 constitute a synchronous rotation, wherein synchronous rotation means that when one of the transmission wheel 22 and the rotating assembly 25 rotates, the other rotates therewith, and when the rotation of one of the transmission wheel 22 and the rotating assembly 25 is restricted, the rotation of the other is restricted therewith. The concept of synchronous rotation is also applicable to other components forming synchronous rotation in this case, and is not described in detail.

The first transmission element 23 and the second transmission element 24 are both configured to rotate synchronously with the central shaft 19.
Therefore, when the central shaft 19 rotates around the central axis, if the first transmission part of the first transmission member 23 contacts the transmission wheel 22 and the second transmission part of the second transmission member 24 is disengaged from the rocker bearing 21, the rotary component 25 can drive the accessories such as the drill bit and the chisel bit to rotate; if the first transmission part of the first transmission member 23 is disengaged from the transmission wheel 22 and the second transmission part of the second transmission member 24 is in contact with the rocker bearing 21, then the impact assembly 26 drives the drill bit, chisel bit and other accessories to reciprocate; if the first transmission part of the first transmission member 23 is in contact with the transmission wheel 22 and the second transmission part of the second transmission member 24 is in contact with the rocker bearing 21, then the rotary component 25 drives the bit, chisel, etc. to rotate and the impact component 26 drives the bit, chisel, etc. to reciprocate.

The first clutch member 28 is slidable relative to the guide member 27, and the second clutch member 29 is also slidable relative to the guide member 27. The rotating member 31 is rotatable about a first axis a perpendicular to the motor axis, and the rotating member 31 has a first supporting portion 311 and a second supporting portion 312 formed thereon. The elastic member 32 includes a first coupling leg 321, a second coupling leg 322, and an elastic coupling portion 323 coupling the first coupling leg 321 and the second coupling leg 322. The first connecting leg 321 contacts the first supporting portion 311, the second connecting leg 322 contacts the second supporting portion 312, and the first connecting leg 321 and the second connecting leg 322 contact the first supporting portion 311 and the second supporting portion 312 from both sides of the first axis a, respectively.
More specifically, as shown in fig. 4 and 5, with respect to the rotating member 31, the first supporting portion 311 and the second supporting portion 312 are respectively provided at different axial positions of the rotating member 31 in the first axis a direction. A spacer 313 may be disposed between the first supporting portion 311 and the second supporting portion 312, and the spacer 313 may be a rib protruding from the first supporting portion 311 or the second supporting portion 312.
The first supporting portion 311 is used for contacting the first connecting leg 321, and the first supporting portion 311 is disposed at a first axial position. The first supporting portion 311 further includes a first supporting surface 311a, and an extending direction of the first supporting surface 311a is parallel to the first axis a. The first support surface 311a also substantially partially surrounds the first axis a, and the first support surface 311a is also formed with a first distal contact point 311b and a first proximal contact point 311c at different circumferential locations thereof. The first distal contact point 311b is farther from the first axis a than the first proximal contact point 311c, such that when the first connecting leg 321 contacts the first distal contact point 311b, the first connecting leg 321 is farthest from the first axis a, and when the first connecting leg 321 contacts the first proximal contact point 311c, the first connecting leg 321 is closest to the first axis a.
The second supporting portion 312 is used for contacting the second connecting leg 322, and the second supporting portion 312 is disposed at a second axial position. The second support portion 312 further includes a second support surface 312a, and the extending direction of the second support surface 312a is parallel to the first axis a. The second support surface 312a also generally partially surrounds the first axis a, and the second support surface 312a is further formed with a second distal contact point 312b and a second proximal contact point 312c at different circumferential locations thereof. Wherein the second distal contact point 312b is further from the first axis a than the second proximal contact point 312c, such that when the second connecting leg 322 contacts the second distal contact point 312b, the second connecting leg 322 is furthest from the first axis a, and when the second connecting leg 322 contacts the second proximal contact point 312c, the second connecting leg 322 is closest to the first axis a.
Further, the first and second connecting legs 321 and 322 are respectively disposed at both sides of the rotating member 31, and the first and second connecting legs 321 and 322 correspond to the positions of the first and second supporting surfaces 311a and 312a, respectively, in the direction of the first axis a.
In addition, the first supporting surface 311a further includes a first revolution body surface (not shown), which is a substantially cylindrical surface, and the cylindrical surface may be a part of the surface of a cylinder centered on the first axis a. The second support surface 312a further includes a second surface of revolution (not shown) that is substantially a cylindrical surface, which may also be a portion of the surface of a cylinder centered on the first axis a. Thus, the first proximal contact point 311c can be disposed on the first revolution solid surface, and the second proximal contact point 312c can be disposed on the second revolution solid surface, so that when the rotation member 31 rotates, if the first connecting leg 321 contacts with the first revolution solid surface, the distance between the first connecting leg 321 and the first axis a can be kept constant; if the second connecting leg 322 is in surface contact with the second rotating body, the distance between the second connecting leg 322 and the first axis a can be kept constant. It is understood that the first proximal contact point 311c is disposed on the first revolution solid surface, and any point on the first revolution solid surface can be regarded as the first proximal contact point 311 c; the second proximal contact point 312c is disposed on the second surface of revolution, and any point on the second surface of revolution may be considered the second proximal contact point 312 c. Similarly, the first distal contact point 311b may be disposed on a surface of revolution, and the second distal contact point 312b may be disposed on a surface of revolution.
Further, a connecting line between a first proximal contact point 311c and a first distal contact point 311b intersects a connecting line between a second proximal contact point 312c and a second distal contact point 312b, so that when the rotating member 31 rotates, the second connecting leg 322 can be driven to be farthest from the first axis a, the second connecting leg 322 can be driven to be closest to the first axis a, or the second connecting leg 322 can be driven to be between the farthest and the closest to the first axis a, thereby realizing different function switching.
