At this time, the two locking columns 116 are located in the pulling frame 106, and do not cooperate with the first fixing hole and the second fixing hole to lock the pulling frame 106. The pulling frame 106 can be pushed and pulled to adjust the height. After the height is suitable, the telescopic button 107 is released, and the two lifting columns 116 are retracted. The lowering spring 110 is reset, and the pressure strip 108 is pushed back to the original position along the two lifting columns 109, driving the telescopic button 107 to reset, and driving the two locking columns 111 to rise, thereby driving the two rollers 113 to rise. Under the elastic force of the locking spring 115 to reset, the locking block 114 is reversely pushed out toward the first fixing hole, driving the locking column 116 to pass through the first fixing hole and the second fixing hole to fix the pulling frame 106. At this time, the height of the pulling frame 106 is fixed, and the pulling frame 106 can be grabbed to drag the device to tilt the box body 10 1 and the drag seat 103, so that only two of the universal wheels 105 of the device touch the ground, and the entire device can be dragged with little effort.
