[0008] When the lock catch mechanism locks the support mechanism in the "I" shaped structure, the support mechanism supports the support frames, and the directional wheels and the universal wheels are placed on the lower surface of the ramming plate. At this time, the movement and steering are realized through the universal wheels, and the whole is conveniently moved under the action of the two directional wheels and the two universal wheels. When the lock catch mechanism is separated from the support mechanism, the support mechanism is in an inverted V-shaped structure, and the two support frames are pulled to overturn upward, so that the directional wheels and the universal wheels are retracted.
