AI Technical Summary
In narrow and complex spaces such as gas pressure regulating boxes, traditional wrenches and socket wrenches are difficult to rotate and apply force effectively, especially when there are obstacles vertically obstructing the bolt head.
A side-insertion disassembly device is designed, including a vertical rod and a wrench head. The wrench head is perpendicular to the vertical rod, the wrench opening faces the insertion direction, and the handle is perpendicular to the insertion direction, allowing the wrench head to be inserted laterally into the bolt head. The distance between the wrench head and the vertical rod can be adjusted to adapt to different spaces.
It enables the effective disassembly of bolt heads in confined spaces, avoiding the problem of traditional tools being unusable due to obstacles, and provides flexible operating space and tightening capabilities.
