AI Technical Summary
Traditional modular hammerheads are prone to loosening and falling off the hammer handle during high-frequency striking operations, which shortens the tool's lifespan and results in poor connection stability, posing safety hazards.
It adopts a dual locking design of plug-in components and limit components. Through the precise fit of the constraint stud and the internal thread, and the multi-angle limit of the rotating plug block and the rotating constraint groove, it ensures a stable connection between the hammer handle and the hammer head. The modular design supports quick assembly and disassembly.
It effectively resists the impact load generated by high-frequency knocking, avoids the loosening of traditional single threaded connections, improves the convenience of operation, and significantly extends the tool life.
