[0028] Specifically, the protective component 4 is installed and fixed by the threaded rod 5 on the fixed ring 3. When the staff needs to adjust the pruning angle, the protective component 4 is moved to rotate it to the required position, and then the threaded rod 5 is rotated for installation and fixation, which can effectively avoid potential safety hazards and improve the flexibility of the device. At the same time, with the cooperation of the flipping mechanism 9, the staff can adjust the pruning angle, which is convenient for the staff to trim the greenery in all directions and further improve the pruning efficiency. Subsequently, with the cooperation of the limiting mechanism 14, the staff can adjust the overall pruning length of the device according to the usage requirements. At the same time, with the sliding and clamping cooperation between the slider 17 and the chute 16, when the telescopic inner rod 7 slides on both sides of the inner wall of the telescopic outer rod 6, the telescopic inner rod 7 is restricted, which is convenient for improving the stability of the overall sliding of the device.

A threaded groove 403 is penetrated through the center of the upper end face of the arc-shaped block 402, and the threaded groove 403 is threadedly connected to each of the four threaded rods 5.

[0030] Specifically, the design of the protective component 4 can effectively avoid the situation where plant debris may splash during the pruning process, reducing potential safety hazards. At the same time, the protective component 4 has an all-round moving function. By rotating the threaded rod 5 to disengage it from the threaded groove 403 on the arc-shaped block 402, and then moving the protective cover 401 to rotate it to the required position, it is convenient for the staff to adjust according to different pruning angles.

[0031] The flipping mechanism 9 includes a rotating shaft 901, two flipping blocks 902, and a worm 904. The rotating shaft 901 is rotatably arranged on both sides of the inner wall of the telescopic outer rod 6. The two flipping blocks 902 are fixedly arranged at positions on both sides of the rear end face of the machine body 1. The two flipping blocks 902 are fixedly sleeved on the outer wall of the rotating shaft 901 near the center position. A worm gear 903 is fixedly sleeved at the center of the outer wall of the rotating shaft 901 and the worm gear 903 is located at the center of the relative side of the two flipping blocks 902.

Under the rotation of the worm gear 903, the rotation of the two flipping blocks 902 on the rotating shaft 901 is driven, thereby realizing the adjustment of the overall angle of the machine body 1 and the front blade 2, enabling the staff to flexibly adjust according to different trimming angles, thereby realizing the all-round trimming of the greenery, and further improving the trimming efficiency and trimming effect.

[0033] Both of the two limiting mechanisms 14 include a moving block 1401, a pull ring 1402 and a limiting block 1404.

Subsequently, the telescopic inner rod 7 can be pulled to adjust it to the required length. Then, the pull ring 1402 is released, and the limiting block 1404 slides and is inserted into the limiting groove 18 under the elastic limit of the spring 1403, so as to adjust and fix the length of the pulled telescopic inner rod 7, thereby realizing the adjustment of the trimming length of the device, facilitating the staff to trim the greenery at a distance or at a high place, and improving the flexibility of the device.

[0035] Working principle: When in use, the staff can assist in holding the device through the handle 8 and the armrest 10. Subsequently, after rotating the protective component 4 to the required trimming angle, it is fixedly installed through the threaded rod 5. At this time, the protective cover 401 can effectively prevent the situation of plant debris splashing during the trimming process. Then, by rotating the worm 904, under the action of the flipping mechanism 9 and the meshing of the worm gear 903 and the worm 904, the rotation of the two flipping blocks 902 on the rotating shaft 901 is driven, thereby realizing the adjustment of the overall angle of the machine body 1 and the front blade 2, enabling the staff to flexibly adjust according to different trimming angles and realizing the all-round trimming of the greenery;

[0036] Secondly, when the staff needs to trim the greenery at a distance or at a high place, by pulling the pull ring 1402, and then with the cooperation of the limiting mechanism 14, the trimming length of the device can be adjusted, facilitating the staff to trim the greenery at a distance or at a high place, improving the trimming efficiency, and further improving the flexibility of the device.
