In some embodiments, as shown in fig. 1 and 2, the transmission mechanism 4 comprises a mounting member 41 and two engaged bevel gears 42, the mounting member 41 being connected to the carrier member 1, each bevel gear 42 being rotatably connected to the mounting member 41, one bevel gear 42 being coaxially connected to the rotating member 3 and the other bevel gear 42 being coaxially connected to the mating member 2. When the bolt 100 is used, the rotating part 3 is rotated, and the rotating part 3 drives the two bevel gears 42 to rotate, so as to drive the matching part 2 to rotate, so that the bolt 100 is disassembled and assembled.

Through setting up drive mechanism 4 into the bevel gear transmission, can make drive mechanism have that drive structure is compacter, and occupation space is less, is favorable to dwindling this bolt assembly and disassembly tools's volume to make this bolt assembly and disassembly tools can stretch into narrower and smaller space in order to carry out the dismouting to bolt 100. In addition, the bevel gear transmission also has the advantages of constant transmission ratio, large borne torque, high transmission efficiency and the like.

As shown in fig. 2 and 3, the rotating member 3 and the bevel gear 42 are coaxially connected by the following structure: the rotating piece 3 is provided with a connecting disc 33, the connecting disc 33 is provided with a plurality of connecting columns 34, the end face of the bevel gear 42 is provided with a plurality of jacks, and the connecting columns 34 are matched with the jacks in a one-to-one correspondence mode. Illustratively, two connecting posts 34 are arranged on the connecting disc 33, and two insertion holes are arranged on the end surface of the bevel gear 42.

The fitting member 2 can also be coaxially connected with the bevel gear 42 by matching the connecting column 34 with the insertion hole, which is not described in detail herein.

In some embodiments, as shown in FIG. 3, each bevel gear 42 is rotatably coupled to the mounting member 41 by a bearing 43. The friction force of the bevel gear 42 during rotation can be greatly reduced by providing the bearing 43, thereby facilitating reduction of the torque of the rotary member 3 when the bolt 100 is disassembled and assembled.

Wherein, the bevel gear 42 and the bearing 43 can be installed in the following way: as shown in fig. 3, the mounting member 41 is provided with a mounting shaft 411, an inner race of the bearing 43 is in interference fit with the mounting shaft 411, and an outer race of the bearing 43 is in interference fit with the center hole of the bevel gear 42.
