AI Technical Summary
The disassembly and repair of existing car fenders are difficult, require professional guidance, consume a lot of time, and the disassembly of surrounding parts can easily cause difficulties in adjusting gaps and surface differences, resulting in high repair costs.
It adopts a combination structure of fasteners and locking components, and uses the cooperation of inclined planes, springs, steel balls, conical platforms and sliding pillars to achieve quick locking and disassembly. The spring force ensures that the fender fits tightly with the body, and the inclined plane enhances the tensile strength.
It enables quick locking and unlocking of car fenders, is simple and fast to operate, has strong clamping stability, avoids tool space limitations and reliance on professionals, and reduces maintenance difficulty and cost.
