[0027] A limiting groove 21 is provided inside the base 2, and the main driving gear 11 and the slave driving gear 63 are located in the limiting groove 21. The main driving gear 11 is located at the center of the limiting groove 21, and the slave driving gear 63 is evenly distributed in a circular array around the hub of the main driving gear 11. The upper and lower ends of the two gears respectively abut against the upper and lower walls of the limiting groove 21 to limit the movement of the gears in the vertical direction.

[0028] Three sliding grooves 22 are opened inside the base 2, and the sliding grooves 22 are matched with the adjusting screw 6 one by one. A slider 61 is fixed to the upper end of the adjusting screw 6. The slider 61 slides along the sliding groove 22, and further drives the supporting foot 4 connected to the adjusting screw 6 to move synchronously. A buffer pad 62 is respectively provided on the outer walls on both sides of the slider 61 along the direction of the sliding groove. When the slider 61 slides along the sliding groove 22 to the extreme positions on both sides, the buffer pad 62 is tightly against the sliding groove 22 to prevent the slider 61 from directly colliding with the sliding groove 22. The buffer pad 62 is made of a highly elastic material, preferably a rubber material.

[0029] There are four moving wheels 3, and a wheel frame 31 is arranged between any one of the moving wheels 3 and the base 2. The wheel frame 31 is an inverted U-shaped frame.
