Technical Problem

[0003]但是起重机在吊运货物时，其吊钩与其上的绳索容易受外力干扰，从而诱发绳索以及货物摆动甚至脱落，不仅会造成货物的损坏，带来较大的经济损失，而且掉落的货物也会造成极大的安全风险

Benefits of technology

[0018] 1. After the hook body hooks the rope, insert the locking pin into the second seat through the limiting groove, thus forming a sealed space inside the hook body to prevent the rope from shaking or even coming off the hook when swinging. After inserting the locking pin, insert the plug through the first insertion hole into the second insertion hole. The magnet in the second insertion hole and the magnet on the plug attract each other, thus limiting the plug and preventing it from slipping out easily. At this time, the plug can further fix the locking pin, preventing the spring from being affected by external force and causing the locking pin to be pulled out of the limiting groove.
