AI Technical Summary
Traditional hole expanders generate a large amount of debris during use, posing safety hazards and being difficult to clean. They also lack effective workpiece fixing devices, resulting in poor hole expansion accuracy and quality.
A hole expander including a protective cover and a unique fixing component is designed. The protective cover consists of a housing 1 and a housing 2 connected by the fixing component. The fixing component consists of a locking block, a locking seat, a locking groove, a locking plate and a spring, which is used to block debris from splashing. The clamping device fixes the workpiece by a bidirectional lead screw and a clamping plate to ensure stable position.
It effectively blocks flying debris, ensures construction safety, facilitates cleaning of the protective cover, improves the accuracy and quality of hole enlargement, ensures the stability of the workpiece position, and avoids safety accidents.
