By setting the sliding groove 3, the slider 4, the connecting sleeve 6, the limiting disc 7 and the fixing plate 8, the limiting disc 7 is driven to rotate by rotating the fixing plate 8, and the limiting disc 7 will drive the connecting sleeve 6 to rotate inside the mounting plate 1 during the rotation process, and the connecting sleeve 6 and the limiting disc 7 can be removed after a certain number of rotations, and then the worn tooth block 5 is pushed after removal, so that it drives the slider 4 to slide inside the sliding groove 3, and the worn tooth block 5 and the slider 4 can be removed for replacement after sliding a certain distance, thereby effectively avoiding the need to replace the entire composite gear after the tooth block 5 is worn, thereby reducing the economic cost.
[0023] See also Figure 1-3Anti-skid ridges 9 are symmetrically fixed on both sides of the fixed plate 8, and the anti-skid ridges 9 improve the anti-skid effect when the fixed plate 8 is rotated. The connecting shaft 2 and the connecting sleeve 6 are slidingly connected, and the assembly effect between the connecting shaft 2 and the connecting sleeve 6 is improved through the sliding connection.
[0024] Embodiment 2
[0025] See also Figure 3-4 The inner wall of the connecting sleeve 6 is symmetrically provided with a limiting groove 10, and the outer wall of the connecting shaft 2 is symmetrically fixedly installed with a limiting strip 11. A baffle 12 is fixedly installed at one end of the connecting shaft 2, and a ring 13 is threadedly connected to the outer wall of the connecting shaft 2. By inserting the connecting shaft 2 into the interior of the connecting sleeve 6, the limiting strip 11 on the connecting shaft 2 will be plugged into the limiting groove 10 provided on the inner wall of the connecting sleeve 6 after the limit distance is inserted. After plugging, the ring 13 is aligned with one end of the connecting shaft 2. After alignment, the ring 13 is rotated again. After a certain number of rotations, the ring 13 will cooperate with the baffle 12 to assemble the connecting shaft 2 and the connecting sleeve 6, thereby improving the assembly efficiency between the connecting shaft 2 and the composite gear and facilitating the operation of the operator. The outer wall of the ring 13 is evenly fixedly provided with anti-skid protrusions 14. The anti-skid effect when the ring 13 is rotated is improved by the anti-skid protrusions 14. The limiting strip 11 is slidably connected with the limiting groove 10, and the anti-deflection effect between the connecting shaft 2 and the connecting sleeve 6 is improved by the sliding connection.
[0026] Working principle: When the compound gear needs to be assembled with the connecting shaft 2, first insert the connecting shaft 2 into the connecting sleeve 6. After the maximum insertion distance, the limit strip 11 on the connecting shaft 2 will be plugged into the limit groove 10 provided on the inner wall of the connecting sleeve 6. After the plugging, align the ring 13 with one end of the connecting shaft 2. After alignment, rotate the ring 13. After a certain number of rotations, the ring 13 will cooperate with the baffle 12 to assemble the connecting shaft 2 and the connecting sleeve 6, thereby improving the assembly efficiency between the connecting shaft 2 and the compound gear and facilitating the operation of the operator. When the tooth block 5 on the composite gear is worn, first rotate the fixing plate 8, and drive the limit plate 7 to rotate through the fixing plate 8. During the rotation process, the limit plate 7 will drive the connecting sleeve 6 to rotate inside the mounting plate 1. After a certain number of rotations, the connecting sleeve 6 and the limit plate 7 can be removed. After removal, the worn tooth block 5 is pushed again, so that it drives the slider 4 to slide inside the slide groove 3. After sliding a certain distance, the worn tooth block 5 and the slider 4 can be removed and replaced, thereby effectively avoiding the need to replace the entire composite gear after the tooth block 5 is worn, thereby reducing the economic cost.
