[0026] Control boards 8 are arranged on both sides of the ladder frame 45. A fixed rod 9 is fixedly connected to one side of the control board 8, and a connecting plate 10 is arranged on the outside of the fixed rod 9.

[0027] A pedal 11 is fixedly connected inside the ladder frame 45. An anti-slip layer 12 is arranged on the top of the pedal 11, and the outside of the control rod 41 is fixedly connected to the inside of the connecting plate 10.

[0028] A first air cylinder 13 is fixedly connected to the bottom of the pedal 11. A piston rod of the first air cylinder 13 is fixedly connected to a second connecting rod 14, and one end of the second connecting rod 14 is fixedly connected to a claw disc 15.

[0029] It should be noted that: driven by the motor 7, the first connecting rod 6 drives the worm 43 to rotate, and then the worm wheel 42 drives the control rod 41 to rotate under the support of the support frame 1. Then, the control rod 41 drives the two connecting plates 10 to move. Under the connection of the fixed rod 9, the ladder frame 45 is pulled to move by the two control plates 8. At the same time, the first guide wheel 44 slides under the limit of the movement guide groove 3, improving the stability of the movement of the ladder frame 45, facilitating the deployment and use or retraction and storage of the ladder frame 45, reducing the occupied space, enhancing the flexibility of the adjustment of the ladder frame 45. The pedal 11 and the anti-slip layer 12 facilitate the staff to step on. Through the support frame 1 and the moving wheels 24 at the bottom of the ladder frame 45, it is convenient to adjust and move the position as needed. Driven by the first cylinder 13, the second connecting rod 14 drives the claw disc 15 to lift and lower, facilitating descending and gripping the ground, improving the stability of the ladder frame 45 during use, and enhancing the safety effect.

[0030] Reference Figure 1 and Figure 4 As shown, the lifting assembly 5 is arranged at the top of the support frame 1. The lifting assembly 5 includes a fixed frame 51, a positioning groove 52 and a second guide wheel 53. The fixed frame 51 is fixedly connected to the top of the support frame 1. The positioning groove 52 is opened inside the fixed frame 51, and the second guide wheel 53 is slidably connected to the inner side of the positioning groove 52.

[0031] The lifting assembly 5 further includes a first support plate 54 and a connecting frame 55. One side of the second guide wheel 53 is fixedly connected to the first support plate 54, and the connecting frame 55 is fixedly connected to the inner side of the fixed frame 51.

[0032] The second support plate 16 is rotatably connected to the inner side of the connecting frame 55. One side of the first support plate 54 is fixedly connected to a positioning rod 17. The first positioning frame 18 is fixedly connected to the outer side of the positioning rod 17. The second cylinder 19 is arranged inside the first positioning frame 18.

[0033] The piston rod of the second cylinder 19 is fixedly connected to a third connecting rod 20. The second positioning frame 21 is arranged on the outer side of the third connecting rod 20. The support frame 22 is arranged on the top of the second support plate 16. The protective frame 23 is fixedly connected to the top of the support frame 22.

[0034] It should be noted that: on one side of the first support plate 54 and the second support plate 16, positioning rods 17 are respectively and fixedly connected. The positioning rods 17 play a role in supporting and fixing the first positioning frame 18 and the second positioning frame 21. Driven by the second cylinder 19, the third connecting rod 20 pushes the two second support plates 16 to move through the second positioning frame 21 and the positioning rods 17. At the same time, the two first support plates 54 drive the two second guide wheels 53 to slide under the limitation of the positioning grooves 52, so that the first support plate 54 and the second support plate 16 drive the four support frames 22 to rise and fall, thereby realizing the rise and fall of the protective frame 23, facilitating the adjustment of the height of the protective frame 23 according to requirements and the height of the tree, and facilitating the pruning work of the staff.

[0035] The working principle of a pruning ladder provided by the present utility model is as follows:

[0036] When in use, under the action of the four moving wheels 24, it is convenient to move the support frame 1 and the ladder frame 45 to the required position. Driven by the first cylinder 13, the second connecting rod 14 drives the claw disc 15 to rise and fall, facilitating descending and gripping the ground, improving the stability of the ladder frame 45 during use, and enhancing the safety effect. The pedal 11 and the anti-slip layer 12 facilitate the staff to step on and enter the protective frame 23. Driven by the second cylinder 19, the third connecting rod 20 pushes the two second support plates 16 to move through the second positioning frame 21 and the positioning rods 17. At the same time, the two first support plates 54 drive the two second guide wheels 53 to slide under the limitation of the positioning grooves 52, so that the first support plate 54 and the second support plate 16 drive the four support frames 22 to rise and fall, thereby realizing the rise and fall of the protective frame 23, facilitating the adjustment of the height of the protective frame 23 according to requirements and the height of the tree, enhancing the flexibility, and facilitating the pruning work. Driven by the motor 7, the first connecting rod 6 drives the worm 43 to rotate, and then the worm gear 42 drives the control rod 41 to rotate under the support of the support frame 1. Then the control rod 41 drives the two connecting plates 10 to move. Under the connection of the fixed rod 9, the ladder frame 45 is pulled to move through the two control plates 8. At the same time, the first guide wheel 44 slides under the limitation of the movement guide groove 3, improving the stability of the movement of the ladder frame 45, facilitating the unfolding use or retracting and storing of the ladder frame 45, and reducing the occupied space.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
