DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 、 2 As shown in Figures 3 and 4, the detachable gear includes a bearing and a gear body 1 arranged on the shaft sleeve 2. The gear body 1 consists of a half gear 3 and a half gear 2 4. Two symmetrical docking holes 5 are provided on the half gear 1 3, and a positioning groove 6 connected to the docking hole 5 is provided on the side of the half gear 1 3. Two symmetrical docking blocks 7 are fixedly connected to the half gear 2 4, and a limiting groove 8 is provided on one side of the docking block 7. A positioning plate 9 is provided on the shaft sleeve 2, and two symmetrical positioning rods 10 are fixedly connected to one side of the positioning plate 9. The half gear 1 3 and the half gear 2 4 are assembled into the gear body 1 through the docking blocks 7 and the docking hole 5, and are installed on the shaft sleeve 2 and are clamped into the positioning groove 6 through the positioning rod 10. One end of the positioning rod 10 is clamped into the limiting groove 8, thereby achieving the assembly and fixation of the half gear 1 3 and the half gear 2 4, making the gear body 1 easy to directly disassemble and improve the efficiency of gear disassembly and assembly.

[0017] Preferably, a threaded sleeve 11 is provided on the shaft sleeve 2, and a thread is provided on the surface of one end of the shaft sleeve 2 for use with the threaded sleeve 11. By rotating the threaded sleeve 11, the movement of the positioning plate 9 can be controlled, thereby controlling the position of the positioning rod 10.

[0018] Preferably, a sliding groove 12 is provided on one side of the positioning plate 9, and a limiting groove 13 connected to the sliding groove 12 is provided on the inner wall of the positioning plate 9. Two symmetrical round rods 14 are fixedly connected to one side of the threaded sleeve 11, and one end of the round rod 14 is fixedly connected to a limiting block 15, and the round rod 14 is located in the sliding groove 12 and the limiting block 15 is located in the limiting groove 13. The limiting block 15 is used in conjunction with the limiting groove 13 so that the threaded sleeve 11 can drive the positioning plate 9 to move, and when the positioning rod 10 is located in the positioning groove 6, rotating the threaded sleeve 11 will not affect the movement of the positioning plate 9.

[0019] Preferably, a guide block 16 is fixedly connected to the inner side of the positioning plate 9, and a guide groove 17 for use with the guide block 16 is provided on the shaft sleeve 2.
