[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3As shown, this embodiment includes a main board 1, a rotating plate 2, a cylinder 3, a curved pull rod 4, a slider 5 and a rubber clamp 6. The main board 1 is rectangular and the four corners of the main board 1 are arranged in four directions of up, down, left and right. Four slide rail grooves 110 are opened on the main board 1. The slide rail grooves 110 are located at the four corners of the main board 1. There are four sliders 5 and the sliders 5 are slidably connected to the slide rail grooves 110. A through hole 120 is opened in the center of the main board 1. A connecting shaft 9 is fixedly installed in the through hole 120. The center of the connecting shaft 9 is also hollow. The center of the rotating plate 2 is connected to the connecting shaft 9. A connecting groove 61 is opened on the rubber clamp 6 and the rubber clamp 6 is connected to one side of the slider 5 through the connecting groove 61. Each slider 5 and the rubber clamp 6 are penetrated and fixed with a first connecting bolt 7. The rotating plate 2 is rectangular and four second connecting bolts 8 are penetrated and fixed on the four corners of the rotating plate 2. The two ends of the curved pull rod 4 are respectively connected with the first connecting bolt 7 and the second connecting bolt 8. The rotation of the rotating plate 2 drives the curved pull rod 4 to rotate.

[0018] like Figures 1 to 3 As shown, the first connecting plate 10 is fixedly connected to the rear side of the slider 5 located above, the number of cylinders 3 is two, and the cylinder 3 has a piston rod 31 extending upward, the first connecting rod 11 passes through the first connecting plate 10 horizontally, and the two ends of the first connecting rod 11 are connected to the piston rod 31, the second connecting plate 12 is fixedly connected to the rear side of the slider 5 located below, the second connecting rod 13 is passed through the second connecting plate 12, and the fixed locking ring 32 is fixedly installed at the bottom of the cylinder 3, the second connecting rod 13 passes through the fixed locking ring 32 and is fixed to the fixed locking ring 32, the first connecting plate 10, the first connecting rod 11, the second connecting plate 12 and the second connecting rod 13 fix the two cylinders 3 to the main board 1 and the slider 5.
