AI Technical Summary
Existing bolts require specific wrenches to tighten, resulting in low versatility and poor ease of tightening.
A screw-on module is installed at the bolt head, including a fixing plate and a telescopic ejector pin. The telescopic ejector pin consists of a support column, a limiting plate and an elastic block, which is compatible with different types of wrenches. By compressing the telescopic ejector pin, a groove that is compatible with the wrench is formed.
It improves the versatility and ease of engagement of bolts, and can be adapted to various types of wrenches for easy engagement.
