Abstract

(57) [Summary] [Purpose] A wrench of each size for hexagon bolts and nuts is put together as a single tool for the convenience of storage and transportation. [Structure] The handle portion of a conventional spanner is shortened, the handle portion and the double-faced mouth portion of each spanner are fitted, and spanners of various sizes are connected and fixed by a leaf spring, a lock pin, and a rotation stopper.

Description

[Detailed description of the device]

[Field of Industrial Application] [0001] This invention is a multi-sized spanner in which a handle portion of each size and a double-faced opening portion are continuously fitted and are combined into a single screw tightening tool by a leaf spring.

[Prior Art] Conventional one-sided spanner with a two-sided opening on one side, double-sided spanner with a two-sided opening on both sides, and a set spanner or two-sided opening with a separate component There was a monkey wrench.

[Problems to be solved by the invention] [a] In the case of a single-ended or double-ended paired wrench, some of them are required to separate one wrench of each size and to take out one of the required size. I lost it, and at the end of the work I had to combine it again. [B] The monkey wrench is difficult to use because it has a certain size on the head even when it is used in a small size.

[Means for Solving the Problem] A single-ended wrench with a short handle is assembled as shown in FIG.

[Operation] With the above-described structure, when using each wrench, loosen the 14 lock handle, and place the A group (combined part of the wrench 1-4) around the 13 lock pin as shown in FIG. Rotate 180 ° so that A group and B group (combined part of spanner 5-7) are at 180 °. When performing the above operation, loosen the 14 lock handle to release the engagement of the concavities and convexities of the spanners 4 and 5 (Fig. 1), lift the spanner of group A and rotate it 180 °, and then tighten the lock pin. The concavo-convex portions of the spanners 4 and 5 are again engaged with each other, and in this state, the spanner 1 and the spanner 7 can be used. Next, for example, when taking out the spanner 3, if the spanners 1 and 2 are lifted at the same time while the lock pin is loosened, the leaf springs 8 and 9 bend and the spanners 2 and 3 are engaged as shown in FIG. As shown in Fig.3-C, rotate it 180 ° and put it on top of the B group and tighten the lock pin. Hold all the spanners of the B group and the spanner 1 and spanner 2 that overlap with them with your hand. It is possible to work with a screw. Next, when using spanner 5 of group B, perform it in the same manner as for spanner 3 above. Loosen the lock pin, lift spanners 6 and 7 and rotate 180 ° and stack it on group A. Lock pin When tightened, the state shown in Fig. 3-D will be obtained. Hold the spanners of group A and spanners 6 and 7 together by hand, and use spanner 5 to screw them. The same procedure can be followed for the spanner 2, spanner 4, and spanner 6 as well.

[Example] [A] As shown in FIG. 1, a leaf spring 8 is spot-welded to the upper surface of a spanner, and a hole is formed at the opposite end of the leaf spring. A leaf spring 9 is spot-welded to the upper surface of the wrench 2 and a hole is formed at the opposite end of the leaf spring. The leaf spring 10 is spot-welded to the upper surface of the wrench 3 and a hole is formed at the opposite end of the leaf spring. A part of the handle of the wrench 4 is made slightly longer and a downward convex portion is provided to make a hole there. Make the handle part of the spanner 5 a little longer and make a recessed part upward and make a hole there. A leaf spring 11 is spot-welded to the lower surface of the wrench 6, and a hole is provided at the opposite end of the leaf spring. A leaf spring 12 is spot-welded to the lower surface of the wrench 7, and a hole is provided at the opposite end of the leaf spring. [B] Make sure that the handle of the wrench 1 is inserted into the two-sided opening of the wrench 2, and then the handle of the wrench 2 is inserted into the two-sided opening of the wrench 3. Combine 2, 3, 4 and this combination is called A group. Combine the spanners 5, 6, and 7 as described above. This combination is group B. [C] Insert the 13 lock pins, which have screwed tips, in the order of leaf springs 8, 9 and 10, spanners 4 and 5, leaf springs 11 and 12 from the upper part of group A to the lower part of group B. [D] 15 Screw the lock pin into the anti-rotation metal fitting, and turn the 14 lock pin handle to tighten it.

Effect of the Invention With the above-described structure, the present invention is small in size, and when working, when using the spanner of the A group, the entire B group becomes a handle, and the spanner of the B group is used. In this case, since the entire A group becomes a handle, it is small and lightweight in comparison with the usable size range.
