[0005] T-shaped blocks are fixedly arranged on both sides of the connecting plate, T-shaped slots are opened on both sides of the supporting frame, the T-shaped blocks are slidably connected to the T-shaped slots, a first spring is fixedly arranged on the right side of the supporting frame, and the other end of the first spring is fixedly connected to the inner wall of the connecting plate.
[0006] The electric screwdriver comprises an output end and a bolt placement slot, wherein the output end passes through the left side of the U-shaped plate and is rotatably connected.
[0007] A hexagonal groove is provided inside the fixing block, and the hexagonal groove is arranged in a stepped shape.
[0008] A handle is fixedly arranged at the bottom of the support frame.
[0009] The left side of the stopper is fixedly connected to the inner wall of the through slot via a second spring.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The utility model has a simple structure and is easy to install and use. By adjusting the relative position between the support frame and the connecting plate and limiting the position by the stop block, the length can be adjusted according to the working range, thereby improving the safety of high-altitude operations. By using an electric screwdriver in conjunction with a fixing block, automatic tightening can be achieved without manual support. BRIEF DESCRIPTION OF THE DRAWINGS
