Through the arrangement of the bottom plate 64, the rack plate 63 and other structures, the rotating rod 60 rotates to realize the movement of the lifting screw 4 and the rack plate 63, so that when the lifting plate 3 rises, the bottom plate 64 moves downward and is supported on the ground. The rotation of the rotating rod 60 and the lifting screw 4 makes it more convenient to adjust the height, and the support of the bottom plate 64 makes the adjustment action more stable.

[0026] See also Figure 1-5 Four universal wheels are installed at the bottom of the base 1, and one side of the lifting plate 3 is fixedly connected to a support frame 10 by bolts.

Due to the sliding of the tooth block 68, the rack plate 63 drives the bottom plate 64 to be supported on the ground, and the rotating rod 60 can still continue to rotate and will no longer drive the rack plate 63 to move, so as to avoid affecting the height adjustment of the lifting plate 3. Through the restriction of the reset spring and the slide groove, the driving gear 67 is reversed to drive the rack plate 63 to reset;

[0029] Furthermore, the positioning rod 8 is pulled to move the positioning block 7, which can then drive the rotating rod 60 to move. The positioning rod 8 is loosened, and the positioning spring drives the positioning block 7 to move and is inserted into the positioning hole 9 to fix the rotating rod 60, thereby ensuring the stability of the base plate 64 and the support and lifting plate 3.
