[0028] The working principle of the present utility model is as follows: during installation, place the circuit board body 9 above the rotating plate 6, press down the circuit board body 9 to drive the rotating plate 6 to rotate. The rotating plate 6 rotates around the fixed rod 4. When rotating, it scrapes the push plate 7 to move leftward. After the rotating plate 6 loses the pressure of the circuit board body 9, the rotating plate 6 is driven by the torsion spring 5 to reset, and the push plate 7 is pushed to move rightward by the spring 8. Cooperating with the right side of the inner side wall of the housing 1, the two ends of the circuit board body 9 are positioned. The rear end of the circuit board body 9 is positioned by the baffle 13. Insert the cover body 2 onto the housing 1, and screw the bolt 20 into the threaded hole 19, then the cover body 2 can be fixed on the housing 1. At this time, the wiring terminal 10 is exposed through the wiring through hole 11, which is convenient for connection with external devices. At this time, the push plate 7 is stuck in the fixed card slot 12, which can prevent the push plate 7 from moving left and right, and complete the installation of the circuit board body 9.
