The roller arrangement is arranged to facilitate movement, and a lifting mechanism 4 is arranged on the inner wall of the base 3; the fence can be lifted as a whole through the arrangement of the lifting mechanism 4, and the lifting mechanism 4 includes a rotating shaft 401, and the outer arc surface of the rotating shaft 401 is rotatably connected to the inner wall of the base 3, and the lifting mechanism 4 can be moved upward as a whole through the driving of the rotating shaft 401, and the inner wall of the base 3 is respectively fixedly connected with a connecting block 405 and a fixing block 408, and the connecting block 405 is located at the left end of the fixing block 408, and both play the role of supporting connection, and the inner wall of the fixing block 408 is rotatably connected with a threaded rod 404, and the two ends of the threaded rod 404 are arc surfaces, and the middle is a threaded surface, and the outer wall of the threaded rod 404 is a threaded surface. The thread is connected to a slider 402, and the slider 402 moves horizontally by rotating the threaded rod 404, and the slider 402 will not separate from the threaded surface of the threaded rod 404. The outer wall of the slider 402 is rotatably connected to an X-shaped plate 403, and the overall length of the X-shaped plate 403 can be changed. The right top end of the X-shaped plate 403 is rotatably connected to a bottom block 407, and the bottom block 407 moves upward by changing the length of the X-shaped plate 403. A through groove for accommodating the X-shaped plate 403 is provided on the top of the base 3, and the through groove is arranged to avoid motion interference. The left top end of the X-shaped plate 403 is rotatably connected to a moving column 411, and the two rotate to avoid motion interference. The inner wall of the base 3 is fixedly connected to a telescopic column 406, and the overall length of the telescopic column 406 can be adjusted, so that the overall lifting operation can be performed. An extension mechanism 5 is provided on the inner wall of the left end of the base 3, and the overall area of ​​the base 3 is enlarged by the extension mechanism 5 to accommodate more staff.

[0034] Reference Figures 2 - 3, the right end of the threaded rod 404 is rotatably connected to the inner wall of the connecting block 405, and the connecting block 405 supports the threaded rod 404. The bottom end of the slider 402 is slidably connected to the inner wall of the base 3, and the sliding between the two prevents the slider 402 from detaching. The right bottom end of the X-shaped plate 403 is rotatably connected to the inner side wall of the connecting block 405, and the rotational setting avoids movement interference. The outer wall of the moving column 411 is slidably connected to the inner wall of the bottom block 407, and the sliding between the two makes the overall length of the X-shaped plate 403 longer. The left end of the threaded rod 404 is fixedly connected to a worm gear 410, and the rotation of the worm gear 410 causes the threaded rod 404 to rotate. The outer arc surface of the rotating shaft 401 is fixedly connected to a worm 409, and the bottom end of the worm gear 410 meshes with the top end of the worm 409. The rotation of the rotating shaft 401 drives the two groups of worms 409 to rotate, thereby causing the corresponding worm gears 410 to rotate, and making the front and rear two groups of X-shaped plates 403 move synchronously.

[0035] Refer to Figure 2 , Figure 4 and Figure 5 , the extension mechanism 5 includes an extension plate 501. The left end of the telescopic column 406 is fixedly connected to a telescopic plate 502. The setting of the telescopic plate 502 can cooperate with the extension mechanism 5. The left end of the telescopic column 406 is fixedly connected to a fixed column 503. The inner wall of the fixed column 503 is slidably connected to a movable column 504. The overall length of the fixed column 503 and the movable column 504 can be adjusted to adapt to and cooperate with the extension mechanism 5. The outer arc surface of the fixed column 503 is fixedly connected to a clamping block 505. The setting of the clamping block 505 plays a limiting role. The inner wall of the clamping block 505 is elastically connected to a plug column 507 through a return spring 508. The bottom end of the plug column 507 is provided with a double inclined surface, and the double inclined surface is provided to facilitate the change of the overall length.

[0036] Refer to Figures 4 - 5 , the outer wall of the extension plate 501 is slidably connected to the left end inner wall of the base 3. The sliding setting enables the extension plate 501 to be stored in the inner wall of the base 3 when not in use. The bottom end of the telescopic plate 502 is fixedly connected to the top end of the bottom block 407. The bottom block 407 is located below the fixed end of the telescopic plate 502. One end of the return spring 508 is fixedly connected to the inner wall of the clamping block 505, and the other end of the return spring 508 is fixedly connected to the outer arc surface of the plug column 507. The outer wall of the plug column 507 penetrates and is slidably connected to the inner wall of the clamping block 505. The setting of the return spring 508 enables the plug column 507 to have a reset and positioning function. The bottom end of the clamping block 505 is inserted into the inner wall of the movable column 504, and the insertion of the two achieves the purpose of preliminary positioning. The inner wall of the plug column 507 is threadedly connected to a bolt 506, and the bottom end of the bolt 506 is threadedly connected to the inner wall of the movable column 504. The bolt 506 plays a role in limiting and fixing the movable column 504.

[0037] Working principle: When relevant personnel need to adjust the height of the guardrail of the base 3, rotate the rotating shaft 401 at this time, so that the rotating shaft 401 drives the two groups of worm gears 409 to rotate. In this way, the two groups of worm gears 409 drive the two groups of worm wheels 410 to rotate. Furthermore, the two groups of threaded rods 404 will also rotate, so that the two groups of sliders 402 move to the right. When the two groups of sliders 402 move to the right, they will drive the X-shaped plate 403 to shorten in the horizontal length and lengthen in the vertical direction. And at this time, the moving column 411 will also move to the right. At this time, the bottom block 407 moves upward, driving the movable end of the telescopic column 406 to move upward. When the adjustment is completed, stop rotating the rotating shaft 401 to complete the fixing operation.

[0038] When it is necessary to extend the overall area of the base 3, just rotate the bolt 506 upward. In this way, the limit of the bolt 506 on the movable column 504 is released. Then, the extension plate 501 can be pulled to the left. At this time, the movable column 504 will move to the left and contact and squeeze the inclined surface of the insertion column 507. When adjusted to a certain extent, at this time, due to the elasticity of the return spring 508, the insertion column 507 is reset to position the movable column 504. If the operator feels that the extended area is appropriate at this time, the bolt 506 can be rotated downward to achieve the limiting purpose.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
