When the driving force receiving assembly 3 is assembled, along the rotation axis L2, at least a part of the pressed portion 342 is located closer to the base 31 than the driving force receiving portion 343, and at least a part of the pressed portion 342 is located outside the space 33, in the radial direction of the base 31, the size of the supporting portion 32 is smaller than the inner diameter of the cylinder 202, and the minimum distance from the pressed portion 342 to the rotation axis L2 is larger than half of the inner diameter of the cylinder 202, so that the pressed portion 342 can abut against the cylinder 202 to cause the driving force receiving portion 343 to be far away from the rotation axis L2, in the direction perpendicular to the rotation axis L2, the driving force receiving portion 343 is located entirely within the space 33, which is to prevent the driving force receiving portion 343 protruding from the space 33 from interfering with the driving force output member 200, and when the size of the supporting portion 32 in the direction perpendicular to the rotation axis L2 is set to be far smaller than the inner diameter of the cylinder 202, the driving force receiving portion 343 is allowed to be located outside the space 33, but in the direction perpendicular to the rotation axis L2, so that the maximum size of the combined body 202 formed by the supporting portion 32 and the receiving portion 343 is still smaller than the inner diameter of the driving force receiving member 34 in the radial direction of the space 33, and the driving force receiving portion 34 can be broken at least one of the driving force receiving member 34 in the radial direction than the space 33 is received by the receiving at least one of the driving force receiving member 34.

As shown in fig. 5, when the driving force receiving member 3 is gradually brought closer to the driving force output member 200, for example, the driving force receiving member 3 gradually comes closer to the driving force output member 200 as the cartridge 100 is mounted, a part of the assembly formed by the supporting portion 32 and the driving force receiving portion 343 enters into the receiving space 203 of the cylinder 202, the tip end surface 204 of the driving force output member 200 contacts the pressed portion 342, the tip end surface 204 presses the pressed surface 342 as the driving force receiving member 3 continues to move toward the driving force output member 200, thereby causing the driving force receiving member 34 to rotate around the rotating portion 341, the driving force receiving portion 343 enters into the engaging opening 205, the force receiving portion 343a is opposed to the driving surfaces 205a/205b in the circumferential direction of the driving force receiving member 3, the rotation axis L1 and the rotation axis L2 are substantially collinear, and at the same time, the driving force receiving portion 343 is also engaged with the stopper surface 2051 of the engaging opening 205, which may be the same as the driving surface 205a/205b or different surfaces, for example, one of such surfaces 205 may be brought closer to the other one of the driving force receiving surfaces 205, and the other driving force receiving surfaces 200.

When the driving force output member 200 rotates about the rotation axis L1, the driving surfaces 205a/205b transmit driving force to the force receiving portion 343a, and finally, the driving force receiving assembly 3 is driven, and at the same time, the driving force receiving assembly 3 may transmit driving force through a driving force transmitting member provided at the base 31, which may be a gear (illustrated as a gear), an irregular polygon, or the like. When the driving force receiving member 3 is required to be disengaged from the driving force output member 200, it is only necessary to apply a force to the driving force receiving member 3 in a direction opposite to the engaging direction, for example, the driving force receiving member 3 gradually moves away from the driving force output member 200 as the cartridge 100 is taken out, so that the driving force receiving portion 343 is disengaged from the stopper surface.

Further, the driving force receiving assembly 3 may be further provided with a restoring member coupled to the driving force receiving member 34 for urging the driving force receiving member 34 to a position not interfering with the cylinder 202, specifically, for urging the driving force receiving portion 343 to move away from the position where the driving force receiving portion 343 is coupled to the driving force output member 200. When the pressed portion 342 is pressed by the tip end surface 204, the restoring member accumulates restoring force, and when the tip end surface 204 is no longer pressed by the pressed portion 342, the restoring force of the restoring member forces the driving force receiver 34 to rotate again (the direction in which the driving force receiver 343 is separated from the joint opening 205), and the driving force receiver 343 returns to the position in which it does not interfere with the inner wall of the cylinder 202.

When a force is applied in a direction opposite to the direction in which the driving force receiving assembly 3 approaches the driving force output member 200, for example, the driving force receiving assembly 3 gradually moves away from the driving force output member 200 as the cartridge 100 is taken out, the driving force receiving portion 343 moves again in a direction approaching the rotation axis L2 until the driving force receiving portion 343 is disengaged from the engagement port 205, and finally, the driving force receiving assembly 3 completes disengagement from the driving force output member 200.

In a state in which the driving force receiving member a31 is disengaged from the driving force output member 200, the driving member a332 and the driven member a331 can be attracted to each other by the attractive force, or the position of the driving member a332 can be controlled so that the driving member a332 and the driven member a331 are not attracted to each other nor repelled from each other. When the receiving end a321 receives the trigger signal, the driving gear a36 rotates, the driving member a332 rotates along with the rotation of the gear a36, and the driving member a31 gradually approaches the driving member 200 along the direction d to complete the combination by setting parameters such as the trigger time/intensity of the trigger signal so that the angle by which the rack a32 drives the gear a36 to rotate satisfies the repulsive force generated between the driving member a332 and the driven member a 331.

When the driving force receiving member a31 needs to be disengaged from the driving force output member 200, the triggering member a32 is triggered again, the gear a36 continues to rotate in the original direction or in the opposite direction, and an attractive force is generated between the driving member a332 and the driven member a331, so that the driving force receiving member a31 is forced to move in the direction opposite to the direction d to be disengaged from the driving force output member 200.

In the present embodiment, the driving member a332 is configured to switch the magnetic force between the driving member a332 and the driven member a331 between the attractive force and the repulsive force by rotating, thereby achieving the purpose of controlling the driving force receiving member a31 to move in the direction d to be coupled with the driving force outputting member 200 and to move in the direction opposite to the direction indicated by the direction d to be uncoupled from the driving force outputting member 200, the reset member 35 in the eighth embodiment can be omitted, and thus, the overall structure of the driving force receiving assembly 3 can be simplified; in view of the operational stability of the driving force receiving assembly 3, the reset member 35 may be continuously provided in the driving force receiving assembly 3, ensuring a quicker disengagement process of the driving force receiving member a31 from the driving force output member 200.
