At this time, the second rack 115 meshing with the gear 114 moves to the left, and the third rack 116 meshing with the gear 114 moves to the right. Under the action of the second spring 110, the small wheel bracket 105 is ejected with the small wheel 104, and the small wheel bracket 105 is blocked by the second limit block 112. At this time, the push plate 103 is released, and under the action of the first spring 109, each component is reset. At this time, the positioning pin 108 is stuck in the second positioning groove 107 to fix the small wheel bracket 105, and the operator can push the device to the designated location; when the device arrives at the designated location and needs to be fixed again, the operator only needs to press the push plate 103 again. At this time, the positioning pin 108 moves out, and under the action of gravity, the small wheel bracket 105 is pressed back to the first limit block 111. At this time, the push plate 103 is released, and the positioning pin 108 is stuck in the first positioning groove 106 to complete the fixation.
