An extension wall 3 is fixedly connected to one side of the moving plate 17. A work basket 4 is provided on one side of the extension wall 3.

[0024] The adjusting groove 6 is provided with a movable component, which includes an explosion-proof motor 9 fixedly connected to one side wall of the adjusting groove 6, and a lead screw 7 fixedly connected to the output end of the explosion-proof motor 9. The other end of the lead screw 7 is rotatably connected to the side wall of the adjusting groove 6. The movable plate 17 is threadedly connected to the circumferential side of the lead screw 7 through a lead screw nut.

[0025] In this embodiment, when a person stands on the work basket 4 and is slightly short of the desired operating position, a switch can be installed on the work basket 4. The switch is connected to the power cord of the explosion-proof motor 9 and can control the start and stop of the explosion-proof motor 9. An explosion-proof hydraulic cylinder is hinged between two adjacent folding arms of the folding arm body 2. When the hydraulic cylinder is started, it can drive the folding arm body 2 to unfold, raising the height of the work basket 4. When the person finds that they are slightly short of the working point, the explosion-proof motor 9 is started. The output end of the explosion-proof motor 9 drives the lead screw 7 to rotate, and the moving plate 17 moves on the surface of the lead screw 7. The moving plate 17 drives the extension wall 3 to move, and the extension wall 3 can push the work basket 4 to move, thereby facilitating height adjustment.

[0026] For further details, please refer to Figure 5 Two limiting rods A8 are fixedly connected between the side walls of the adjusting groove 6, and the moving plate 17 is slidably connected to the circumferential side of the two limiting rods A8.

[0027] In this embodiment, the moving plate 17 moves on the circumferential sides of the two 8s, which can improve the movement stability of the moving plate 17.

[0028] For further details, please refer to Figure 2 and Figure 4 The upper end of the work basket 4 is provided with a lifting groove 15, and a railing 5 is slidably installed in the lifting groove 15. Two sets of lifting components are provided at the lower end of each railing 5 for raising and lowering the railing 5.

[0029] In this embodiment, the height of the railing 5 can be adjusted according to the user's height, which can improve the protection of the work basket 4.

[0030] Further details are shown in the figure. The lifting component includes a chute 10 opened at the upper end of the work basket 4, and a spring 12 is fixedly connected to the inner bottom wall of the chute 10.

The limiting components include a limiting groove 19 opened on one side wall of the lifting groove 15. A limiting rod B18 is fixedly connected between the side walls of the limiting groove 19. The railing 5 is slidably connected to the circumferential side of the limiting rod B18 through a limiting plate.

[0035] In this embodiment, the lifting groove 15 slides up and down on the surface of the limiting rod 18, which can improve the movement stability of the railing 5.

[0036] The implementation principle of the above embodiment is as follows: When a person stands on the work basket 4 and is a little short of the position to be operated, a switch can be installed on the work basket 4. The switch is connected to the power cord of the explosion-proof motor 9 and can control the start and stop of the explosion-proof motor 9. An explosion-proof hydraulic cylinder is hinged between two adjacent folding arms of the folding arm body 2. When the hydraulic cylinder is started, it can drive the folding arm body 2 to unfold, raising the height of the work basket 4. When the person finds that the distance to the work point is a little short, the explosion-proof motor 9 is started. The output end of the explosion-proof motor 9 drives the lead screw 7 to rotate. The moving plate 17 moves on the surface of the lead screw 7. The moving plate 17 drives the extension wall 3 to move. The extension wall 3 can push the work basket 4 to move, thereby facilitating the adjustment of the height.
