[0029] Specifically, when in use, hold the handle 4, align the wrench 11 with the screw and rotate it. When encountering a narrow or angled situation, the angle between the fixed part 1 and the movable part 2 can be changed through the rotating component inside the movable part 2. The connection between the fixed part 1 and the movable part 2 is an arc-shaped structure and the two are slidingly connected. The telescopic component inside the connecting part 3 can adjust the distance between the handle 4 and the connecting part 3, thereby extending the overall length. At the same time, the angle adjustment range of the fixed part 1 is increased, thereby improving applicability.
[0030] As an implementation method in this embodiment, Figure 2 As shown, the rotating assembly includes a worm 21 which is laterally rotatably connected to the inside of the movable part 2, and the inside of the movable part 2 is vertically rotatably connected to a rotating rod 22. The outer wall of the rotating rod 22 is fixedly connected to a symmetrical connecting block 24, and a worm wheel 23 is fixedly sleeved between the connecting blocks 24 and on the outer wall of the rotating rod 22. The worm wheel 23 is meshed with the worm 21. Both ends of the worm 21 extend to the outside of the movable part 2 and the ends are fixedly connected to a rotating shaft 25. The worm 21 can be driven to rotate more conveniently through the rotating shaft 25. The rotating shaft 25 can be used on both sides, so that the movable part 2 can be adjusted in different situations, thereby improving adaptability.
[0031] Specifically, the worm 21 is rotated by rotating the rotating shaft 25, and the worm 21 drives the worm wheel 23 to rotate.
