The first lifting column 200 can be lifted and lowered relative to the fixed column 100 through the first lifting mechanism, and at the same time, the second lifting column 300 is lifted and lowered relative to the first lifting column 200 through the second lifting mechanism. The first lifting mechanism and the second lifting mechanism have simple structures, and such a synchronous lifting method improves the stability of operation.

[0042] In an optional manner of this embodiment, an articulated seat 430 is provided between the first lifting assembly 410 and the platform 400 , and the first lifting assembly 410 and the platform 400 are hingedly connected via the articulated seat 430 .

[0046] In an optional manner of this embodiment, the first lifting mechanism includes a steering pulley 510, a first fixed column pulley 520, a second fixed column pulley 530, a first lifting pulley 540, a second lifting pulley 550, a tightening seat 560 and a wire rope 570. The steering pulley 510 is fixedly arranged at the bottom of the fixed column 100, the first fixed column pulley 520 and the second fixed column pulley 530 are respectively fixedly arranged on both sides of the top of the fixed column 100, the first lifting pulley 540 and the second lifting pulley 550 are respectively installed on both sides of the bottom of the first lifting column 200, the tightening seat 560 is fixedly arranged on the fixed column 100, and the wire rope 570 is sequentially passed through the steering pulley 510, the first fixed column pulley 520, the first lifting pulley 540, the second lifting pulley 550 and the second fixed column pulley 530, and tightened by the tightening seat 560.

During the lifting and lowering process of the first lifting column 200, due to the change in the height of the first sprocket 710 and the second sprocket 720, the first lifting sprocket 730 and the second lifting sprocket 740 will complete the synchronous follow-up lifting and lowering with the change in the length of the chain 750. Since the first lifting sprocket 730 and the second lifting sprocket 740 are fixedly installed at the bottom of the second lifting column 300, the synchronous lifting and lowering of the second lifting column 300 is also achieved.

[0052] In an optional manner of this embodiment, the first lifting column 200 is provided with a third guide wheel group 810 and a fourth guide wheel group 820 spaced apart along the height direction, the third guide wheel group 810 and the fourth guide wheel group 820 both include a plurality of guide wheels, and the second lifting column 300 is attached to the outer periphery of the guide wheel.
