[0033] Implementation process: In the initial state, such as Figure 1 As shown, the right end of the lifting plate 8 is located in the first transmission cavity 3, the wheels 7 are against the ground, and the supporting device can be moved by the wheels 7.

[0034] After moving to the designated position, the motor 20 is started, and the output shaft of the motor 20 drives the turntable 18 and the transmission bar 19 to rotate 180 degrees clockwise, and the transmission bar 19 pushes the lifting plate 8 to the left, so that the elastic telescopic plate 9 is compressed, and the top plate 13 moves upward under the elastic force of the first elastic member 12, and the lifting plate 8 is pushed upward by the top plate 13. The lifting plate 8 stops after moving up a distance, so that the wheel 7 is stored in the storage cavity 2, and the bottom wall of the base 1 contacts the ground to prevent the wheel 7 from sliding.

When the lifting plate 8 moves to the same horizontal position as the first transmission chamber 3, the lifting plate 8 moves to the right under the elastic force of the elastic telescopic plate 9, and the right end of the lifting plate 8 re-enters the first transmission chamber 3, so that the wheel 7 contacts the ground, so as to use the wheel 7 to move the supporting device.

[0036] The first roller 14 can reduce the friction between the top plate 13 and the lifting plate 8, so that the lifting plate 8 and the top plate 13 can move left and right when they are against each other. The second roller 29 can reduce the friction between the second rack 28 and the lifting plate 8, so that the lifting plate 8 and the second rack 28 can move left and right when they are against each other. The third roller 15 and the fourth roller 16 can reduce the friction between the first transmission cavity 3 and the lifting plate 8, so that the lifting plate 8 can move left and right in the first transmission cavity 3.

[0037] The present invention rotates the output shaft 17 on the motor 20 in different directions, so that the transmission bar 19 pushes the movement of different components, thereby driving the lifting and lowering and fixing of the lifting plate 8 and the wheel 7, so as to quickly realize the use and storage of the wheel 7, so that the user can move and fix the supporting device.
