The moving direction of the slider 8 in the fixed plate 4 is a fixed direction, thereby realizing the fixed direction movement of the fixing rod 9, thereby realizing the fixed direction movement of the extrusion block 14. A positioning plate 10 is fixedly connected to the right side of the fixing rod 9, and a telescopic rod 12 is fixedly connected to the inner side of the positioning plate 10, and an extrusion block 14 is fixedly connected to the inner side of the telescopic rod 12. A strong spring 13 is provided on the outside of the telescopic rod 12. The strong spring 13 has strong elasticity, so that when the extrusion block 14 is squeezed, it rebounds to give the extrusion block 14 a strong force, thereby realizing the clamping effect of the extrusion block 14.

[0034] A plurality of wiring terminals 3 are fixedly connected inside the box body 1, and the wiring operation of the external cable is realized through the wiring terminals 3. A limit spring pin 7 is fixedly connected to the bottom of the inner wall of the fixed sleeve 2, and the limit spring pin 7 is located inside the limit hole 6.

A slide rod 11 is slidably connected inside the positioning plate 10, and the slide rod 11 is fixedly connected to the outer wall of the extrusion block 14. One end of the strong spring 13 is connected to the positioning plate 10. One side of the turntable 18 is fixedly connected, the other end of the strong spring 13 is fixedly connected to the outward side of the extrusion block 14, and the inward side of the extrusion block 14 is fixedly connected with an anti-slip pattern 15.
