The hydraulic cylinders 3 are evenly distributed between the opposite surfaces of the first support plate 1 and the second support plate 2, and the straight lines where the multiple hydraulic cylinders 3 are located are parallel to each other and are all located in the same plane. One of the two hydraulic cylinders 3 located at the outermost side is connected to the first support plate 1, and the other of the two hydraulic cylinders 3 located at the outermost side is connected to the second support plate 2. The bending plate 4 is installed between two adjacent hydraulic cylinders 3. The rectangular cylinder 5 is sequentially sleeved on the multiple hydraulic cylinders 3, and the center lines of the multiple rectangular cylinders 5 overlap with each other and the adjacent two rectangular cylinders 5 can slide with each other. The rectangular cylinder 5 located at the outermost side is connected to the first support plate 1, and the rectangular cylinder 5 located at the innermost side is connected to the second support plate 2.

The plane where the second support plate 2 is located is parallel to the plane where the first support plate 1 is located, and a space for installing other parts is formed between the opposite surfaces of the two. The hydraulic cylinders 3 are evenly distributed between the opposite surfaces of the first support plate 1 and the second support plate 2, and the straight lines where the hydraulic cylinders 3 are located are parallel to each other and are all located in the same plane, and are all used to provide driving force. One of the two outermost hydraulic cylinders 3 is connected to the first support plate 1, and the other of the two outermost hydraulic cylinders 3 is connected to the second support plate 2 to change the distance between the second support plate 2 and the first support plate 1. The bending plate 4 is respectively installed between two adjacent hydraulic cylinders 3 for transmitting driving force.
