DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Referring to Figures 1 to 4 As shown, the utility model provides a technical solution: a pruning shear for garden trees, including a first scissors rod 1 and a second scissors rod 2, the surfaces of the first scissors rod 1 and the second scissors rod 2 are rotatably connected, and connecting pipes 5 are slidably connected to the surfaces of both the first scissors rod 1 and the second scissors rod 2. Adjustment mechanisms 6 are provided on the surfaces of both the first scissors rod 1 and the second scissors rod 2, and the adjustment mechanism 6 includes a chute 61, and the chute 61 is opened on the surfaces of the first scissors rod 1 and the second scissors rod 2.

[0031] Referring to Figures 1 to 4As shown in the figure, in this embodiment: A sliding column 65 is slidably connected to the inner wall of the sliding groove 61. The cross-section of the sliding column 65 is in a "T" shape. A rotating ring 63 is threadedly connected to the arc surface of the sliding column 65. One end of the rotating ring 63 is fixedly connected to a pressing ring 62. The pressing ring 62 is an elastic rubber ring. The pressing ring 62 abuts against the surface of the first scissors rod 1. The other end of the sliding column 65 is fixedly connected to a fixing plate 66. The fixing plate 66 is fixedly connected to the surface of the connecting pipe 5. By rotating the rotating ring 63, the rotating ring 63 drives the pressing ring 62 to separate from the surface of the first scissors rod 1, releasing the fixing effect between the connecting pipe 5 and the first scissors rod 1. Then, when the connecting pipe 5 is slid to a suitable position, the effect of adjusting the length of the pruning shear is achieved.

[0032] Refer to Figures 1 to 4 As shown in the figure, in this embodiment: A plurality of anti-slip lines 64 are evenly formed on the arc surface of the rotating ring 63, increasing the friction between the hand and the rotating ring 63. It is convenient to rotate the rotating ring 63.

[0033] Refer to Figures 1 to 4 As shown in the figure, in this embodiment: A locking mechanism 3 is provided on the surfaces of the first scissors rod 1 and the second scissors rod 2. The locking mechanism 3 includes a rotating frame 31. The rotating frame 31 is fixedly connected to the surface of the first scissors rod 1. A rotating plate 33 is rotatably connected to the inner wall of the rotating frame 31. A screw rod 35 threadedly penetrates through one end of the rotating plate 33 away from the rotating frame 31. A fixed circular plate 36 is threadedly connected to the arc surface of the screw rod 35. The fixed circular plate 36 is fixedly connected to the surface of the second scissors rod 2. By providing the locking mechanism 3, it is prevented that the first scissors rod 1 and the second scissors rod 2 accidentally open when not in use, thereby avoiding the occurrence of accidental scratches.

[0034] Refer to Figures 1 to 4 As shown in the figure, in this embodiment: A magnet 34 is fixedly connected to the surface of the first scissors rod 1 corresponding to the position of the rotating plate 33. The rotating plate 33 is an iron plate. The magnet 34 adsorbs with the rotating plate 33, preventing the problem that the rotating plate 33 rotates when using the first scissors rod 1 and the second scissors rod 2, affecting the normal use, and playing a role in adsorbing the rotating plate 33.

[0035] Refer to Figures 1 to 4 As shown in the figure, in this embodiment: Two coil springs 32 are sleeved on the inner wall of the rotating frame 31. The two ends of the coil springs 32 are respectively fixedly connected to the rotating frame 31 and the rotating plate 33. The torsional force generated by the coil springs 32 during the process of rotating the rotating plate 33 avoids the phenomenon that the rotating plate 33 shakes.

[0036] Refer to Figures 1 to 4 As shown in the figure, in this embodiment: Protective sleeves 4 are sleeved on the surfaces of both the first scissors rod 1 and the second scissors rod 2, preventing the first scissors rod 1 and the second scissors rod 2 from accidentally scratching others.

[0037] Refer to Figures 1 to 4As shown, in this embodiment: an anti-slip sleeve 7 is fixedly connected to the surface of the connecting pipe 5, which is convenient for the operator to use the pruning shears.

[0038] The working principle of a pruning shears for garden trees provided by the present utility model is as follows. When in use, first remove the protective sleeve 4. When the branches to be pruned are at a relatively long distance, the length of the pruning shears is changed through the provided adjusting mechanism 6. First, rotate the rotating ring 63, and the rotating ring 63 drives the pressing ring 62 to separate from the surface of the first scissors rod 1, releasing the fixing effect between the connecting pipe 5 and the first scissors rod 1. Then, when the connecting pipe 5 is slid to a suitable position, the effect of adjusting the length of the pruning shears is achieved. Then, rotate the rotating ring 63 again, and the rotating ring 63 drives the pressing ring 62 to come into pressing contact with the first scissors rod 1, realizing the fixing effect between the connecting pipe 5 and the first scissors rod 1. Then, operate the second scissors rod 2 in the same steps; when there is no need to prune branches, rotate the rotating plate 33 in the direction of the fixed circular plate 36. During this process, the torsional force generated by the torsion spring 32 prevents the rotating plate 33 from shaking. Then, rotate the screw 35 until the screw 35 is screwed into the rotating circular plate, realizing the fixing effect between the first scissors rod 1 and the second scissors rod 2.

[0039] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present utility model and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
