By setting a drive box in the utility model, turning the rotary block can drive the connecting shaft to rotate, then drive the driving wheel to rotate, then drive the driven wheel to rotate, and then the driven wheel meshes to drive the tooth groove to rotate, so as to drive the moving block to move, and then drive the second handle to move, so as to achieve the purpose of adjusting the length of the handle. By setting a baffle plate, the staff can apply pressure to its upper surface to make it move downward, then drive the second fixing block to move, then drive the second cylindrical block to move, then drive the second connecting block to move, and then drive the spring to contract. At this time, the staff can put the cable into the hook, and then release the baffle plate, and the spring restores its deformation, so that the baffle plate can automatically rebound, so as to achieve the purpose of preventing the cable from falling off the hook.

[0004] The above-mentioned utility model can adapt to the usage habits of different staff by changing the length of the adjusting handle. However, through the cooperation between the rack and the sliding groove, the adjusted length is limited and cannot be used when exceeding the set length, so the scope of use is small.
