One outer wall of the mounting plate 23 is provided with a movable frame 30, and the movable frame 30 is slidably connected to the outer wall of the side support rod 42. A first spring 29 is connected between the movable frame 30 and the side support rod 42;

[0054] A protective cover 31, which is installed on the side of the mounting plate 23 close to the rotating rod 33;

[0055] A sleeve 40, which is mounted on an outer wall of one side of the rotating rod 33;

[0056] The slide 38 has a limit block at its end, which is slidably connected to the inner wall of the sleeve 40. One end of the slide 38 is connected to the inner wall of the sleeve 40 through a second spring 39. A pressure block 35 is installed on the slide 38. A contact switch 36 is installed on the outer wall of one side of the mounting plate 23. When the contact switch 36 is triggered, the electromagnet in the mounting plate 23 works.
