[0027] Further, the sleeve mechanism includes a hexagonal sleeve 31 sleeved on the bolt of the gear reducer body 1, the hexagonal sleeve 31 is a sleeve for clamping the bolt, and the function is to be sleeved on the bolt and fastened, and the disassembly and installation of the bolt can be completed by rotating the sleeve. The top end of the hexagonal sleeve 31 is fixedly connected with a rotating rod 32 movably penetrating the sliding seat 3, the top end of the rotating rod 32 is fixedly connected with a secondary gear 33 engaged with the gear belt 234, the upper surface of the secondary gear 33 is fixedly connected with a top block 34 clamping the gear belt 234, and the top block 34 clamps the gear belt 234 to prevent the gear belt 234 from coming out of the secondary gear 33. The middle part of the gear belt 234 is engaged with a main gear 21, the lower surface of the main gear 21 is rotatably connected with the clamping seat 2, the upper surface of the main gear 21 is fixedly connected with a clamping plate 22 clamping the gear belt 234, and the clamping plate 22 clamps the gear belt 234 to prevent the gear belt 234 from coming out of the main gear 21. The upper surface of the clamping plate 22 is fixedly connected with a hexagonal block 23, and the hexagonal block 23 is sleeved with a tool (a tool for disassembling the bolt), so as to provide more stable and reliable locking or connection.

[0028] The clamping mechanism includes a base 4 fixedly connected to the card holder 2. A support sleeve 41 is fixedly connected to the top of the base 4. A return spring 44 is installed inside the support sleeve 41. The return spring 44 drives the U-shaped clamping block 43 to keep the gear belt 234 tightly clamped by the L-shaped slide rod 42. The two ends of the return spring 44 are fixedly connected to the ends of the corresponding L-shaped slide rod 42. The two ends of the support sleeve 41 are slidably fitted with L-shaped slide rods 42. The top of each L-shaped slide rod 42 is fixedly connected to a U-shaped clamping block 43 that clamps the gear belt 234.

[0029] Furthermore, a pair of cylinders 24 are fixedly connected inside the card holder 2, and each end of the sliding seat 3 near the card holder 2 is fixedly connected to an insert plate 35.

[0030] In this embodiment, when a bevel gear reducer is required, such as Figure 1 As shown, first, the bottom of the hexagonal sleeve 31 is firmly fitted onto the bolt on the gear reducer body 1. Then, a tool is used to clamp the hexagonal block 23, causing the tool to rotate the hexagonal block 23. The rotated hexagonal block 23 then rotates the clamping plate 22, which in turn rotates the main gear 21. Since the main gear 21 is meshed with the gear belt 234, the main gear 21 drives the gear belt 234 to rotate. Furthermore, since the gear belt 234 is meshed with a pair of secondary gears 33, the gear belt 234 drives the pair of secondary gears 33 to rotate. Subsequently, the secondary gears 33 sequentially drive the bottom rotating rod 32 and the hexagonal sleeve 31 to rotate. Because the hexagonal sleeve 31 firmly clamps the bolt, the rotated hexagonal sleeve 31 allows for the removal and installation of the bolt. When the bolt spacing on each pair of gear reducer bodies 1 is different, a pair of cylinders 24 inside the clamping seat 2 are simultaneously activated. The piston rod of each cylinder 24 pushes the corresponding insert plate 35 to move, and the insert plate 35 then pushes the sliding seat 3 to move. This allows the sliding seat 3 to sequentially drive the rotating rod 32 and the hexagonal sleeve 31 to move until the pair of hexagonal sleeves 31 can be locked onto the pair of bolts. Simultaneously, during this process, the pair of L-shaped sliding rods 42, through the elastic tension of the return spring 44 inside the support sleeve 41, cause the L-shaped sliding rods 42 to drive the U-shaped clamping block 43 to tightly hold the gear belt 234, thereby ensuring a tight meshing connection between the gear belt 234 and the main gear 21.
