Detailed Description

The invention is further described below with reference to the accompanying drawings.

Embodiment 1, an adjustable insulating horizontal ladder hook for equipotential operation, comprising a frame 5, wherein a fixed sleeve 7 is arranged at the tail end of the frame 5, two main U-shaped wheels 4 are arranged on the frame 5, the two main U-shaped wheels 4 are connected through a chain 12, a rotating gear 13 is arranged on the chain 12, and the rotating gear 13 is provided with a rotating handle 14; the machine frame 5 is provided with a through hole 11 and a clamping block I3, a vertical column 1 is arranged in the through hole 11, an auxiliary U-shaped wheel 17 is arranged below the vertical column 1, the auxiliary U-shaped wheel 17 is connected with the vertical column 1 through a U-shaped wheel fixing piece 16, and the vertical column 1 is further provided with a clamping block II 2; the upper end of the vertical column 1 is provided with a stop block 18, and a pressure spring 9 is arranged between the stop blocks 18.

Embodiment 2, an adjustable insulating horizontal ladder hook for equipotential operation, wherein a hook I6 and a hook II 8 are arranged on a frame 5; the U-shaped wheel fixing piece 16 is provided with a sliding groove 15, a rotating column 20 is arranged below the upright post 1, the tail end of the rotating column 20 is provided with a convex column 19, and the convex column 19 is arranged in the sliding groove 15; the sliding groove 15 is provided with an arc groove 21; the block 18 is provided with a pressing handle 10, and the rest is the same as that of the embodiment 1.
