[0006] The support assembly includes a support plate and a screw rod. The screw rod slides through the base body. The support plate is fixedly installed at the bottom of the screw rod. The top of the screw rod is threadedly connected in the bracket. Four universal wheels are arranged at the bottom of the base body.

[0007] The support assembly also includes two movable plates, which are symmetrically rotatably mounted on the support plate. Two sliding grooves are arranged at the bottom of the base body, and the two movable plates are slidably connected in the two sliding grooves respectively.

[0008] Furthermore, a circular groove is provided on the top of the base body, and the rotating disk is rotatably installed in the circular groove.

[0009] Furthermore, the support assembly also includes four engaging blocks, which are respectively fixedly installed on both sides of the two movable plates, and the inner walls on both sides of the two slide grooves are provided with engaging grooves, and the engaging blocks are slidably installed in the engaging grooves.

[0010] Furthermore, the base assembly also includes a snap ring, which is fixedly mounted on the inner wall of the circular groove, and an annular groove is formed on the outer wall of the rotating disk, and the snap ring is adapted to the annular groove.

[0011] Furthermore, the rotating assembly also includes a plurality of balls, which are equidistantly mounted on the bottom of the rotating disk. An arc groove is formed on the inner wall of the bottom of the circular groove, and the balls are matched with the arc groove.

[0012] Furthermore, the support assembly also includes a plurality of anti-skid pads, which are equidistantly arranged at the bottom of the support plate.

[0013] Technical effects and advantages of the utility model:
