[0015] like Figures 1 to 3 As shown, a special retaining ring disassembly tool comprises a first movable part 1 and a second movable part 2, wherein the first movable part 1 and the second movable part 2 are connected and assembled together by a movable fastening assembly 3, and the upper ends of the first movable part 1 and the second movable part 2 are disassembly operation heads 4, which cooperate with the opening position of the retaining ring when in use, and can open the retaining ring when in later use. The lower ends of the first movable part 1 and the second movable part 2 are operating handle hand-held parts, and the upper end of the disassembly operation head 4 is a conical structure, ensuring that the space occupied during initial placement is smaller. The position between the upper ends of the first movable part 1 and the second movable part 2 can fit tightly together, forming a V-shaped space after opening, and the top of the disassembly operation head 4 is an arc-shaped structure, which has better fluidity during placement and can meet the requirements of matching placement in a relatively small space. A disassembly and assembly stop safety block 5 is provided on the outer side of the width direction of the first movable part 1 and the second movable part 2 near the disassembly operation head 4, so that the matching stability after placement is better and the safety during use is higher. It is designed with a symmetrical structure as a whole. When in use, the main movable support shaft is used as a fulcrum for movable coordination, so that the retaining ring can be opened and disassembled accurately and conveniently. When disassembling, it can effectively solve the technical problem of difficulty in disassembly and assembly when the space is relatively small. In addition, the retaining ring is not easy to fall off during the disassembly process, and the safety during the disassembly process is better.

[0016] The overall structure of this tooling product is relatively simple, and the production and use costs are relatively low. The chain will not be damaged during the disassembly process. When in use, it can be used to disassemble the retaining rings of various chains, and the application range is wider.

[0017] Preferably, a hand-held anti-slip structure is provided at the hand-holding portion of the operating handle, which is more convenient when performing hand-held operation and has better stability during operation.

[0018] Preferably, the disassembly stop safety block 5 is connected to the first movable component 1 or the second movable component 2 in a detachable manner, so that the production cost is lower and the flexibility in use is greater. In addition, the specifications of this structure can be more flexibly replaced as needed, so that the overall application range is wider.

[0019] Preferably, the disassembly and assembly stop safety block 5 is connected to the first movable component 1 or the second movable component 2 by bolt fastening, which reduces the cost of fastening.

[0020] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
