[0020] By adopting the above technical solution, the disassembly and assembly parts provided inside the support frame 1 are aligned with the positions of the two groups of chain link connecting pins. At this time, the two groups of first knobs 6 can be turned to drive the first screw rods 11 inside the two groups of fixing frames 2 to rotate, so that the threaded blocks 12 respectively threadedly connected to the surfaces of the two groups of first screw rods 11 can drive the lower fixed block 4 fixedly connected on one side to move, and cooperate with the upper fixed block 3 provided therein to clamp and fix the adjacent chain links, and the elastic anti-slip pads 5 provided can not only improve the stability of the clamping, but also avoid the wear of the chain link surface due to excessive clamping force. At this time, the overall related components can be fixed on the chain link without manual holding. At this time, the position of the disassembly and assembly parts can be adjusted by turning the second knob 7, and the chain links can be disassembled and assembled using the disassembly and assembly parts.

[0021] Reference Figure 1 and Figure 3 The disassembly and assembly parts include a second knob 7, a threaded sleeve 8, a threaded rod 9, a handwheel 10, a second screw rod 13, a sliding rod 14 and a rubber sleeve 15. The bottom of the second knob 7 is fixedly connected to the second screw rod 13. The bottom of the second screw rod 13 rotates through the support frame 1 and extends to the inside of the support frame 1. The bottom of the second screw rod 13 is rotatably connected to the inside of the support frame 1 through a rotating shaft. The surface of the second screw rod 13 is threadedly connected to the threaded sleeve 8. The inner cavity side wall of the threaded sleeve 8 is slidably connected to the sliding rod 14. Both ends of the sliding rod 14 are fixedly connected to the inner cavity side wall of the support frame 1.

One end of the threaded rod 9 is fixedly connected to the handwheel 10, and the end of the threaded rod 9 away from the handwheel 10 is fixedly connected to the rubber sleeve 15.

[0022] By adopting the above technical solution, the second screw rod 13 inside the fixing frame 2 can be driven to rotate by rotating the second knob 7, and the threaded sleeve 8 can be driven to move in cooperation with the limiting effect of the sliding rod 14 on the threaded sleeve 8, so that the position of the threaded rod 9 can be adjusted so that one end of the threaded rod 9 is aligned with one end of the connecting pin of the chain link, and the threaded rod 9 connected to the rotation of the inner cavity side wall of the threaded sleeve 8 can be driven to rotate by rotating the hand wheel 10. At this time, the connecting pin connecting the two groups of chain links can be ejected through the threaded rod 9 to be disassembled, and the rubber sleeve 15 provided at one end of the threaded rod 9 can avoid direct contact between the threaded rod 9 and the connecting pin, which causes wear between the threaded rod 9 and the connecting pin. Conversely, the connecting pin can also be inserted into the chain link to assemble the chain link.

[0023] The implementation principle of the bulldozer chain link disassembly and assembly tool of the embodiment of the present application is as follows: the disassembly and assembly parts provided inside the support frame 1 are aligned with the positions of the two groups of chain link connecting pins. At this time, the two groups of first knobs 6 can be turned to drive the first screw rods 11 inside the two groups of fixing frames 2 to rotate, so that the threaded blocks 12 respectively threadedly connected on the surfaces of the two groups of first screw rods 11 can drive the lower fixing block 4 fixedly connected on one side to move, and cooperate with the upper fixing block 3 provided therein to clamp and fix the adjacent chain links, and the elastic anti-skid pad 5 provided therein can not only improve the stability of its clamping, but also avoid the wear of the chain link surface caused by excessive clamping force. At this time, the overall related components can be fixed on the chain link without manual holding. At this time, the second screw rod 13 inside the fixing frame 2 can be driven to rotate by turning the second knob 7, and the threaded sleeve 8 can be driven to move by cooperating with the limiting effect of the sliding rod 14 on the threaded sleeve 8, so as to achieve the effect of the screw sleeve 8 being moved. The position of the threaded rod 9 can be adjusted so that one end of the threaded rod 9 is aligned with one end of the connecting pin of the chain link. By turning the hand wheel 10, the threaded rod 9 connected to the inner cavity side wall of the threaded sleeve 8 can be driven to rotate. At this time, the connecting pin connecting the two sets of chain links can be ejected through the threaded rod 9 to be disassembled. The rubber sleeve 15 provided at one end of the threaded rod 9 can avoid direct contact between the threaded rod 9 and the connecting pin, which causes wear between the threaded rod 9 and the connecting pin. Conversely, the connecting pin can also be inserted into the chain link to assemble the chain link. The overall structure is simple, and the cost and maintenance cost during the later use are relatively low. At the same time, it is easy to operate and use. It can be directly fixed on the chain link for use without manual holding. The connecting pin of the chain link can be pushed, thereby realizing the disassembly and assembly of the chain link, reducing the work intensity of the staff and effectively improving the work efficiency of the staff.
