The mounting frame 301 is movably connected to the upper portion of the base frame 1, and the base plate 302 is movably connected to the lower portion of the base frame 1. Bolts 303 are movably connected to both sides of the mounting frame 301. The bolts 303 pass through the mounting frame 301 and the base plate 302 in sequence.
