The telescopic rod 104 is a prior art. The telescopic rod 104 is composed of a sleeve and a sleeve rod with one end limited and movably connected to the inside of the sleeve. A spring 105 is arranged on the outside of the telescopic rod 104. The two ends of the spring 105 are respectively fixedly connected to the movable plate 102 and the clamping plate 103. The other side of the plate 102 is symmetrically fixedly connected with a connecting rod 106, and the connecting rod 106 is slidably connected to the fixed plate 101.
