[0022] A connecting rod 10, a mounting rod 11 is mounted on the surface of the connecting rod 10, and a gear body 12 is mounted on the surface of the mounting rod 11;

[0023] The disassembly mechanism 20 is mounted on the surface of the mounting rod 11 and can disassemble and assemble the gear body 12;

[0024] The disassembly and assembly mechanism 20 includes two mounting rings 21 sleeved on the surface of the mounting rod 11. The two mounting rings 21 are mounted on both sides of the gear body 12. A plurality of slots 22 are provided on both sides of the gear body 12. A clamping block is fixedly installed on the adjacent side of the two mounting rings 21, and the clamping block is engaged with the slot 22. A mounting assembly 23 is installed through the interior of the mounting ring 21. The mounting assembly 23 is used to lock the gear body 12. The mounting assembly 23 includes a threaded hole 231 provided on the surface of the gear body 12 and the mounting ring 21. A bolt 232 is installed through the interior of the threaded hole 231. The bolt 232 is threadedly connected to the threaded hole 231 on the surface of the gear body 12.

[0025] In this embodiment, the connecting rod 10 is separated from the transmission shaft, and the bolt 232 is rotated to separate from the threaded hole 231. When the bolt 232 separates from the threaded hole 231, the annular block is simultaneously separated from the wedge block 234, releasing the tightness of the wedge block 234. When the wedge block 234 is released from the restraint, the insertion rod 235 is separated from the mounting rod 11 by the rebound of the return spring 236, and the gear body 12 can be disassembled for maintenance.

[0026] In this embodiment, a limiting groove 237 is provided at the inner ring of the gear body 12 and the mounting ring 21, and a limiting rod 238 is fixedly installed on the top of the mounting rod 11. The limiting groove 237 and the limiting rod 238 are slidably connected; they can maintain the overall stability of the gear body 12, the mounting rod 11 and the mounting ring 21, and limit the gear body 12 when it is working to ensure the stability of the gear body 12 when it is working.
