The movable support bar 22 is slidably supported on the pair of guide rails 236 through the slider 235. The screw nut 231 of the screw nut pair is embedded in the movable support bar 22, and the two ends of the screw 232 are rotatably supported on the bottom plate 1 through the support seat 234 and penetrate the movable support bar 22 and the fixed support bar 21 in the direction parallel to the guide rail 236. The movable support bar 22 can be connected to the angle plate at the side, and the angle plate is fixedly connected to the bottom plate of the bolt and nut assembly, wherein the bottom plate is provided with a waist-shaped hole that matches the bolt of the bolt and nut assembly.
