Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Example 1

Referring to Figures 1-4, a double-ended wrench includes a mounting head 7 and a fixed head 12. One end of the mounting head 7 is rotatably connected to a pin shaft 10, and a wrench plate 8 is fixedly installed on the outside of the pin shaft 10, and the wrench plate 8 passes through the pin shaft 10. It can be rotated with the installation head 7, and the angle of the wrench plate 8 can be adjusted conveniently, so as to improve the convenience of use. The wrench plate 8 is provided with a wrench groove 9, at least one pair of wrench grooves 9 are arranged, and along the wrench plate 8 The central axis is distributed in a circular array, and the shape of the wrench groove 9 is shown in Figure 1. In order to improve the scope of application of the wrench, the wrench groove 9 of different sizes can be used to match bolts and nuts of different sizes. The matching wrench groove 9 is arranged in the wrench plate 8, so as to avoid the need to repeatedly replace different types of wrenches during use.

Moreover, the wrench plate 8 is simple in structure, and the cost is lower than that of an adjustable wrench of adjustable size, and the wrench plate 8 is not easy to rust, and the adjustable wrench will easily rust after a long period of use. In addition, the wrench plate 8 Just set the matching wrench groove 9 on the outside of the bolt and nut directly, and the use efficiency is higher than that of the adjustable wrench.

One side of the fixed head 12 is threadedly connected with a first mounting bolt 13, and a wrench 14 is movable inside one end of the fixed head 12. The restriction and fixation of the bolt 13 can facilitate the fixing of the wrench 14, and facilitate the removal of the wrench 14 through the first mounting bolt 13. According to the accompanying drawing 4, the wrench 14 can be a dead wrench and a ring wrench, and has various models, which can be used according to specific conditions. It is necessary to use an adapted wrench, which has a wide range of applications, and as shown in Figure 4, the structure of the wrench and the torx wrench used in the device are relatively small. The size of the wrench used in the device is much smaller, which is convenient to carry and reduces the user's load.

An adjustment member is fixedly connected between the other end of the installation head 7 and the other end of the fixed head 12. The adjustment member includes a sleeve rod 1, a fixed rod 2, a pole 3, a block 5 and a fastening rod 6, and one end of the fixed rod 2 is connected to the fixed head. 12 is fixedly connected, and the other end is fixedly connected with one end of the support rod 3, one end of the sleeve rod 1 extends to the inside of the installation head 7, and one side of the installation head 7 is threaded with a second installation bolt 15, and the second installation bolt 15 extends to the inside of the installation head 7 The end of the rod 1 is in conflict with the end of the sleeve rod 1, and the other end of the rod 3 is slidably arranged in the sleeve rod 1. The inside of the rod 3 is provided with a bar-shaped groove 4, and the block 5 is slidably arranged inside the bar-shaped groove 4. The sleeve rod 1 A fastening rod 6 is threadedly connected to one side near the end of the fixed rod 2, and the end of the fastening rod 6 penetrates and extends to the inside of the strip groove 4 and is fixedly connected with the block 5. According to the attached drawing 3, the The width is less than the width of the strip groove 4, when the fastening rod 6 is rotated, the distance that the block 5 penetrates into the strip groove 4 can be adjusted, and when the distance between the sleeve rod 1 and the fixed rod 2 needs to be adjusted, the tightening The fixed rod 6 drives the block 5 to move so that the block 5 does not contact the inner wall of the bar groove 4. At this time, adjust the distance between the sleeve rod and 1 and the fixed rod 2, and then reversely rotate the fastening rod 6 to drive The block 5 moves, and the block 5 is in conflict with the inner wall of the bar groove 4, and the length between the sleeve rod 1 and the pole 3 is fixed to complete the adjustment of the length of the double-ended wrench.

The length direction of the strip groove 4 is the same as the length direction of the pole 3, and the sleeve rod 1, the fixed rod 2 and the pole 3 are coaxially arranged. By adjusting the distance between the pole 3 and the inside of the sleeve rod 1, the sleeve rod 1 and the pole 3, the length of the double-ended wrench can be adjusted. The outer surfaces of the sleeve rod 1 and the fixed rod 2 are fixedly provided with an anti-skid layer 11, and the anti-skid layer 11 plays an anti-skid effect. During use, the existing wrench will slip if the user's palm is wet, and the anti-skid layer 11 can To solve this problem, and the inside of the wrench is made of metal, the anti-slip layer 11 can also play an insulating role when working on live equipment.

Working principle: the double-ended wrench can be easily adapted to different types of bolts and nuts through the wrench plate 8 during use. It is more convenient, and the installation head 7 and the sleeve rod 1 are fixed by the second installation bolt 15, which is convenient for disassembling the installation head 7, so that the wrench plate 8 can be disassembled as required, and can be installed and fixed through the fixing head 12 Different types of dead wrenches or different types of ring wrenches, and the structure of the wrench is smaller than the existing wrench, which can reduce the load, and the distance between the sleeve rod 1 and the fixed rod 2 can be adjusted by rotating the fastening rod 6 , so that the length of the double-ended wrench can be adjusted, and the length of the double-ended wrench can be adjusted according to specific needs.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
