[0035] In this embodiment, when in use, the mounting base 1 is sleeved on the electric line pole, and the threaded rod 107 inside the rotating slot 101 is used to drive the movable frame 103 on the surface to move relative to it, so that the top plate 104 on the surface of the movable frame 103 contacts the top of the pole to increase the supporting force, and at the same time, the surface of the rubber pad 105 is provided with an anti-skid groove 106, which increases the anti-skid force when in contact with the pole, and at the same time, the guide rod 102 limits the movable frame 103 to prevent tilting during movement, so that it can be quickly installed on the surface of the electric line pole, reducing the time of high-altitude operations and improving safety performance.

[0036] In Embodiment 2, the threaded rod 107 is movably embedded in another notch 101, and an inclined block 108 is fixedly installed at a symmetrical position on the surface of the mounting seat 1. A positioning hole 113 is provided on the inner wall of the mounting seat 1 near the inclined block 108. The two positioning holes 113 are sleeved on the outer surface of the mounting block 202.

At the same time, the guide rod 102 limits the mobile frame 103 to prevent tilting during movement, so that it can be quickly installed on the surface of the electric line pole, reducing the time of high-altitude operations and improving safety performance. At the same time, by aligning the limiting groove 205 on the surface of the mounting block 202 with the inclined block 108, the overall material of the supporting steel member 2 is a rigid material with a certain ductility. , so that the mounting block 202 moves along the inclined block 108 to the inside of the positioning hole 113. When the inclined surface 204 on the surface of the mounting block 202 contacts the inclined groove 112 on the surface of the circular shaft 111, the limiting piece 110 on the surface of the circular shaft 111 is driven to move. The two ends of the spring 109 are connected to the surface of the mounting seat 1 and the limiting piece 110, providing a reset ability for the limiting piece 110.
