AI Technical Summary
The maintenance and replacement of existing safety chucks are inconvenient to disassemble and the threads are severely worn, which affects equipment maintenance efficiency and downtime.
It adopts a short thread structure and spring-driven locking mechanism, combined with a rubber layer design, to achieve quick disassembly and enhanced clamping effect. It can achieve single-action unlocking through short-distance turning, avoiding thread wear.
It significantly simplifies the maintenance process, reduces disassembly time, lowers equipment downtime, improves clamping torsional strength, and eliminates vibration and noise.
