The movable block 2261 moves to move the second sliding sleeve 2262, thereby releasing the limit on the fixing assembly 227. By rotating the second connecting plate 2257, the fixing assembly 227 is moved out of the receiving slot 3 2253. , the inner wall of the storage slot 4 2254 is moved out, and the rotating fixing assembly 227 is moved out from the inner wall of the storage slot 5 2258. The angle of the fixing assembly 227 is adjusted according to actual needs. The connecting block 2275 is rotated by rotating the rotating rod 2276, thereby driving the connecting disk 2274 to rotate. The rotation of the connecting disk 2274 drives the screw rod 2273 to rotate on the inner wall of the internal threaded sleeve 2271, thereby pushing the ground plug 2277 to move, so that the ground plug 2277 is inserted into the ground. When the drive motor 161 is started, the linkage mechanism of the entire system ensures the smooth expansion and contraction of the operating frame, greatly improving the safety and convenience during use. In addition, the adjustment flexibility of the support frame is further enhanced through the internal threaded sleeve 2271 and the screw rod 2273, allowing the user to fine-tune according to actual needs, ensuring the stability and adaptability of the operating frame in different working environments. The ground plug 2277 ensures the stability of the support frame on the ground and prevents it from sliding or tipping over during use.

[0039] 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.
