At the same time, the meshing transmission of the gear 163 and the inner toothed belt 23 enables the fixed rod 1 221 of the support assembly 22 to rotate through the gear 2 223 to realize the expansion and folding of the support structure. The limit plate 1 222 and the limit plate 2 224 ensure that the support assembly 22 remains stable during the expansion process to prevent overturning. The limiting assembly 226 and the fixing assembly 227 in the connecting shell 225 push the push plate 2265 so that the push plate 2265 drives the movable block 2261 to move, thereby driving the second slide bar 2263 to slide on the outer wall of the second slide bar 2263 and squeezing the spring 2264, so that the movable block 2261 moves so that the second slide sleeve 2262 moves, thereby releasing the limiting of the fixing assembly 227, and rotating the second connecting plate 2257 so that the fixing assembly 227 moves out of the receiving slot 3 2253. , move out of the inner wall of the storage slot four 2254, then rotate the fixing assembly 227 to move out from the inner wall of the storage slot five 2258, adjust the angle of the fixing assembly 227 according to actual needs, rotate the rotating rod 2276 to rotate the connecting block 2275, and then drive the connecting disk 2274 to rotate, and drive the spiral rod 2273 to rotate on the inner wall of the internal threaded sleeve 2271 through the rotation of the connecting disk 2274, so as to push the ground plug 2277 to move, so that the ground plug 2277 is inserted into the ground. When the driving motor 161 is started, the linkage mechanism of the entire system ensures the smooth expansion and folding of the operating frame, greatly improving the safety and convenience during use. In addition, through the internal threaded sleeve 2271 and the spiral rod 2273, the adjustment flexibility of the support frame is further enhanced, so that the user can make fine adjustments according to actual needs to ensure the stability and adaptability of the operating frame in different working environments. Through the ground plug 2277, the stability of the support frame on the ground is ensured to prevent sliding or tipping during use;

[0038] By starting the driving motor 2 35, the rotating shaft 2 34 drives the screw rod 36 to rotate, and then the slider 2 37 moves linearly along the slide rod 3 38 under the action of the outer wall thread of the screw rod 36. The movement of the slider 2 37 drives the connecting plate 3 30 and the movable plate 2 301 to expand or retract. At the same time, the movable connection of the sliding sleeve 39 on the slide rod 3 38 ensures the smoothness and stability of the entire extension process, so that the operating frame can be flexibly adjusted according to different working height requirements, further enhancing the use range and adaptability of the operating frame, simplifying the operation process, and improving work efficiency.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
