Further, a handle is arranged on one side of the dismounting body far away from the beating part. The handle and the beating part are arranged on two opposite sides of the dismounting body, so that the gravity center of the dismounting tool can be ensured to be positioned in the middle, and the dismounting tool is convenient for operators to carry and use.
Further, the handle is connected with the disassembly body in a welding mode. The connection is firmer.
Further, the beating part and the handle are coaxially arranged, and the beating part and the handle are connected to the middle parts of the corresponding side surfaces. Further guarantee the center of assembly and disassembly tools, make things convenient for operating personnel to use assembly and disassembly tools.
Further, the weight phase-match of beating portion and handle further guarantees assembly and disassembly tools's balance, facilitates the use.
Further, the locating plate is of a plate-shaped structure, and the locating plate is parallel to the upper surface of the end cover of the shock absorber. The two are parallel to each other, so that the lamination can be completed, the contact area of the two is further increased, and the stress is more uniform.
The beneficial effects of the invention are as follows:
1. according to the invention, the end cover is installed and disassembled by using one device, and the end cover can be arbitrarily switched between the disassembly and the installation by using different surfaces of the device, so that the device has the advantages of simple structure, convenience in disassembly and assembly, no damage to the shock absorber, high efficiency and single person operation.
2. The bracket is provided with the fixing rod movably connected with the bracket in a penetrating way, an operator can step on the fixing rod by feet and then knock the end cover upwards to detach the end cover, so that the phenomenon that the shock absorber falls down in the knocking process is avoided.
