Description
Technical Field
The invention relates to the technical field of sockets, in particular to a locking socket.
Background
The socket technology on the market is quite mature, but the work in the anti-loose field is still deficient. In particular, in the field of engineering anti-loosening, the existing anti-loosening basically utilizes the action of a spring to generate pretightening force. The pre-tightening force can be damaged along with the time, the deformation of the copper sheet can not be well compensated, and the deficiency of the pre-tightening force can be caused. The lack of pre-tension can cause arcing, which can cause significant damage to the copper sheet. So to address this problem we use additional force to supplement the loss of pretension.
