The two sliding sleeves (3022) are respectively fixedly connected to the middle of the two sliding rods (3029), and the remaining sliding sleeves (3022) are slidably connected to the sliding rods (3029). One side of the sliding sleeve (3022) is fixedly connected to the connecting rod (30310). A first spring (3024) is fixedly connected to the upper part of the sliding sleeve (3022). An upper support plate (3023) is fixedly connected to the top of the first spring (3024). Two fixed blocks (3031) are fixedly connected to the upper part of the upper support plate (3023). A dovetail slide plate (3021) is fixedly connected to the lower part of the upper support plate (3023). The dovetail slide plate (3021) is slidably connected in the dovetail groove (3028). The dovetail groove (3028) is opened in the sliding sleeve (3022).
