[0024] In the embodiment, asFigure 1 , Figure 2 and Figure 3 As shown, the locking anti-slip assembly includes side plates 6 installed at both ends of the top of the fixed frame 1. A sliding groove is provided on one side of the side plate 6, and a sliding plate 7 is slidably connected to the inner side of the sliding groove. Both the sliding groove and the sliding plate 7 have T-shaped cross sections. A connecting bracket is installed at the other end of the sliding plate 7. First, according to the actual needs of the worker, the worker can hold the overlapping seat 3 on the extension rod 2 and pull it outward. After the extension rod 2 is extended to a sufficient length, the worker can press the sliding plate 7 and slide it inside the sliding groove to squeeze and retract the first spring 9 until the bottom surface of the sliding plate 7 contacts the surface of the rubber pad 12, so that the pressure plate 15 slides into the pressure groove and probes into the inner side of the contact groove as the rubber pad 12 is squeezed.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a rubber pad 12 is installed on the top of the base 8, and a pressure groove is formed at the top of the rubber pad 12. A contact groove is formed inside the base 8 on one side of the pressure groove. A restraining plate 13 is installed at both ends of the inner wall of the contact groove. A restraining groove is formed on the opposite side of two adjacent sets of restraining plates 13. A squeezing block 14 is slidably connected to the inner side of the restraining groove. A second spring is installed between one side of the squeezing block 14 and the inner wall of the restraining groove. A pressure plate 15 is installed on one side of the sliding plate 7 and is slidably connected to the pressure groove.
