A pivot rotating handle mechanism
This utility model discloses a pivot rotation handle mechanism, including an insulating housing and a lever component and conductive terminals disposed on the insulating housing. The insulating housing has a plug-in opening for inserting wires. In this solution, the installation structure and position of the pivot joint in the lever component are improved. The conductive terminals and the protrusions on the bottom wall of the insulating housing cavity form a hole for the pivot joint to connect, which helps to improve the assembly speed. Moreover, the pivot joint on the side of the arm is basically located at the bottom wall of the insulating housing cavity. This design structure helps to lengthen the lever arm, thereby allowing the lever component to be turned with less force, which is more labor-saving.
