[0024] The effect achieved by the whole embodiment 1 is that when adjusting length, staff pulls pulling plate 14, pulling plate 14 drives placing plate 11 and clamping block 12 to move, first spring 10 is compressed, then staff pulls extension plate 3, extension plate 3 drives support 2 to move, when the distance between two supports 2 is the required length, staff releases pulling plate 14, the elastic force of first spring 10 pushes clamping block 12 to enter clamping groove 8, at this time, extension plate 3 is fixed, finally, staff rotates handle 33, handle 33 drives threaded rod 32 to rotate, in turn drives connecting block 34 to enter connecting groove 35, at this time, pulling plate 14 is fixed, it can prevent pulling plate 14 from being mistaken and making clamping block 12 separate from clamping groove 8.

[0025] As shown in embodiment 2, Figures 1-5 Further, fixed groove 15 is arranged on the inner wall of through hole 13, second spring 16 is fixedly installed on the inner wall of fixed groove 15, baffle 17 is fixedly installed on the one end of second spring 16.

[0026] Further, first base 5 is fixedly installed on the top of the two supports 2, press spring bolt 20 is fixedly installed on the top of first base 5, first press spring 18 is arranged on the top of first base 5, top plate 19 is arranged on the top of first press spring 18, press spring bolt 20 is passed through top plate 19, first nut 21 is threadedly connected on the outer wall of press spring bolt 20.

[0027] Further, storage groove 6 is arranged on the outer wall of lifting guide rod 1, storage rack 7 is arranged in storage groove 6, fixed hole 27 is passed through and is arranged on the inner wall of storage rack 7, for connecting storage rack 7 with lifting guide rod 1.

[0028] Furthermore, a second base 22 is fixedly installed on the inner wall of the storage rack 7, and a second compression spring 23 is provided on the outer wall of the second base 22. A pressure plate 24 is provided at one end of the second compression spring 23, and the pressure plate 24 is connected to the second base 22 by screws.

[0029] Furthermore, a second nut 25 is fixedly installed on the outer wall of the lifting guide rod 1, and an adjusting bolt 26 is threadedly connected inside the second nut 25.

[0030] Furthermore, both supports 2 are equipped with vertical guide wheels 4 at their bottom, and the storage rack 7 is equipped with horizontal guide wheels 28 inside.

[0031] The effect achieved by the entire embodiment 2 is that when the staff pulls the pull plate 14, the pull plate 14 pushes the baffle 17 to move, the baffle 17 enters the fixed groove 15, and the second spring 16 is compressed. When the staff releases the pull plate 14, the elastic force of the second spring 16 pushes the baffle 17, so that it enters the through hole 13. The baffle 17 can block the through hole 13 and prevent dust from entering the limiting groove 9.

[0032] Working Principle: During use, the operator places the vertical guide wheel 4 against the inner wall of the column guide rail. Then, by rotating the first nut 21, the nut 21 descends along the compression bolt 20, pressing against the top plate 19, which in turn applies pressure to the first compression spring 18, thus applying pressure to the vertical guide wheel 4 onto the column guide rail. The vertical guide wheel 4 moves up and down along the column guide rail. The elasticity of the first compression spring 18 ensures the horizontal accuracy of the lift and reduces vibration during operation. Then, the operator rotates the adjusting bolt 26, which applies pressure to the pressure plate 24. Under the action of the second compression spring 23, this pressure is applied to the horizontal guide wheel 28. This pressure acts on the guide rails of the left and right limiting surfaces of the column, thus providing elastic limiting for the left and right movement of the lift. When adjusting the length, the operator pulls the pull plate 14, which moves the placement plate 11 and the locking block 12, compressing the first spring 10. Then, the operator pulls the extension plate 3, which moves the bracket 2. When the distance between the two brackets 2 is the required length, the operator releases the pull plate 14, and the elastic force of the first spring 10 pushes the locking block 12 into the slot 8. At this time, the extension plate 3 is fixed. Finally, the operator rotates the handle 33, which rotates the threaded rod 32, thereby moving the connecting block 34 into the connecting groove 35. At this time, the pull plate 14 is fixed, which prevents the pull plate 14 from being accidentally touched, thus causing the locking block 12 to disengage from the slot 8. When the staff pulls the pull plate 14, the pull plate 14 pushes the baffle 17 to move, and the baffle 17 enters the fixed groove 15. The second spring 16 is compressed. When the staff releases the pull plate 14, the elastic force of the second spring 16 pushes the baffle 17, so that it enters the through hole 13. The baffle 17 can then block the through hole 13 to prevent dust from entering the limiting groove 9.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
