One end of the screw rod 52 penetrates through the connecting seat 3 and extends into the covering sleeve 51 to be fixedly connected with a circular plate 53. The circular plate 53 is rotatably connected inside the covering sleeve 51. A guiding slider 54 is fixedly connected to the bottom of the covering sleeve 51, and a pressing rod 55 is fixedly connected to the top of the covering sleeve 51.
