Description

Disassembly tool

The present invention is related to dismounting tools.

Various connection structures are often designed between components, and the common methods are socket and plug-in combinations, such as: setting connectors in the through holes on the frame. And some of the two components will rotate relative to each other, so some will be installed with shock-absorbing bushings, and some will be equipped with bearings...etc. When replacing parts, the common disassembly method is that maintenance personnel directly take a tool and insert it into the hole against the embedded object, and then beat it with a mallet, and the embedded object is ejected from the hole through the impact force of the hammer. It is easy to damage the inner wall of the insert and the perforation, and the frame structure is easy to receive unnecessary impact during the disassembly process, which will affect the structural stability.

Therefore, it is necessary to provide a novel and progressive disassembly tool to solve the above-mentioned problems.
