[0031] A gas rod 130 is also arranged inside the inner cavity 110, and the gas rod 130 is connected to the fork-scissor mechanism 140, and the gas rod 130 pushes the lifting plate 200 to move up and down through the fork-scissor mechanism 140;

[0032] The upper and lower sides of the lifting plate 200 are respectively connected with a top cover 210 and a base 220 for sealing.

[0033] As an embodiment of the present utility model: the fork-scissor mechanism 140 includes a first L-shaped fixing member 141, a second L-shaped fixing member 142, a first cross arm 143, a second cross arm 144 and a third L-shaped fixing member 145, and the first cross arm 143 and the second cross arm 144 are connected by a third fixing pin;

[0034] The self-locking slide rail 120 is composed of a slide groove 121 and a slider 122. The slide groove 121 is fixed on the inner surface of the inner cavity 110. The slider 122 is movably connected in the slide groove 121. One end of the slider 122 is connected to the third L-shaped fixing member 145. During actual sliding, the slider 122 moves up and down with the lifting plate 200. The existence of the slide groove 121 and the slider 122 makes the movement of the lifting plate 200 more stable.

[0035] The first L-shaped fixing member 141 is fixed to the inner surface of the inner cavity 110. A first sliding groove is formed on the surface of the first L-shaped fixing member 141. The tail of the first cross arm 143 is slidably connected to the first sliding groove through a first movable bolt.

[0036] The second L-shaped fixing member 142 is fixed to the inner surface of the inner cavity 110 and contacts the self-locking slide rail 120 , and the tail of the second cross arm 144 is connected to the second L-shaped fixing member 142 through a second fixing pin;

[0037] The third L-shaped fixing member 145 is fixed to the bottom of the lifting plate 200. A second sliding groove is formed on the surface of the third L-shaped fixing member 145. The top of the second cross arm 144 is slidably connected to the second sliding groove through a second movable bolt.

[0038] The top of the first cross arm 143 is connected to one side of the third L-shaped fixing member 145 through a first fixing pin and is away from the second sliding groove.

[0039] The first fixing pin, the second fixing pin and the third fixing pin are a bearing structure. The top of the first cross arm 143 can be rotated at a certain angle through the first fixing pin, and the tail of the second cross arm 144 can be rotated at a certain angle through the second fixing pin.

[0041] The gas rod 130 can be connected to an external wireless controller, and the movable stroke of the gas rod 130 can be set in the pre-setting.

[0042] During actual use, the second cross arm 144 is pushed by the gas rod 130. At this time, the tail of the second cross arm 144 rotates around the second fixed pin, and the top of the second cross arm 144 slides in the second sliding groove along with the second movable bolt. As the second cross arm 144 rotates, the tail of the first cross arm 143 slides in the first sliding groove along with the first movable bolt, and the top of the first cross arm 143 rotates along the first fixed bolt, thereby lifting the lifting plate 200.

[0043] As an embodiment of the present utility model: the top of the column 100 has a through hole 150 , the bottom of the through hole 150 is connected with the inner cavity 110 , and the lifting plate 200 moves up and down along the through hole 150 .

[0044] See also Figure 3 to Figure 4 As an embodiment of the utility model: the top cover 210 and the base 220 are a sealing ring with a trapezoidal cross section, and the top cover 210 and the base 220 are symmetrically arranged on the upper and lower sides of the lifting plate 200.

[0045] The top cover 210 has a first groove, and the top of the lifting plate 200 is fixed in the first groove. The base 220 has a second groove, and the tail of the lifting plate 200 is fixed in the second groove. When the lifting plate 200 is lifted up and down, if the lifting plate 200 is in a raised state, at this time, the top of the base 220 is located in the through hole 150 to achieve a sealing effect. If the lifting plate 200 is in a falling state, at this time, the tail of the top cover 210 is located in the through hole 150 to achieve a sealing effect. The existence of the top cover 210 and the base 220 enables the lifting plate 200 to seal the inner cavity 110 regardless of whether it is in an ascending or falling state, thereby preventing external debris from falling into the inner cavity 110.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
