The main shaft body 17 is arranged in the installation box 1, and the outer walls of the four limiting wheels 6 abut against the outer wall of the main shaft body 17. The shock absorbing component 18 includes a cover plate 1801, and the two sides of the inner wall of the installation box 1 are respectively connected to the two sides of the cover plate 1801, and the bottom of the cover plate 1801 is connected to the top of the damping sleeve 1802.
