[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: A portable pruning device for garden greening maintenance, comprising:

[0027] Two shrinkage tubes 7 for shrinkage are provided. A handle 1 is arranged on the left side of the shrinkage tube 7. A pair of scissors handles 3 are fixedly connected to the shrinkage tube 7. A rotating piece 6 is rotatably connected between the shrinkage tube 7 and the scissors handles 3. The right end of the scissors handles 3 is connected to a rotating ring 5. The right end of the front scissors handle 3 is rotatably connected to the outer wall of the upper rotating ring 5, and the right end of the front scissors handle 3 is fixedly rotatably connected to the outer wall of the lower rotating ring 5. The right end of the rear scissors handle 3 is rotatably connected to the outer wall of the lower rotating ring 5, and the right end of the rear scissors handle 3 is fixedly rotatably connected to the outer wall of the upper rotating ring 5. Cutting blades 10 for trimming are fixedly connected to the outer walls of both rotating rings 5. A sliding rod 8 is slidably connected inside the shrinkage tube 7. Limiting strips 17 are fixedly connected to both the upper and lower sides of the sliding rod 8. Sliding grooves are formed on both the upper and lower sides of the shrinkage tube 7, and the limiting strips 17 are slidably connected in the sliding grooves. A first threaded rod 18 is threadedly connected inside the sliding rod 8. The left end of the sliding rod 8 is fixedly connected to the right end of the handle 1. The right end of the first threaded rod 18 is fixedly connected to the left side of the rotating piece 6. The two rotating rings 5 are connected by a rotating shaft 9, and the rotating shaft 9 is rotatably connected inside the rotating rings 5. Two anti-collision rods 2 are fixedly connected to the rear side of the front shrinkage tube 7;

[0028] Specifically, by rotating the rotating ring 5, the first threaded rod 18 is rotated, so that the sliding rod 8 slides in the shrinkage tube 7 under the restriction of the limiting strip 17, thereby pushing the handle 1 outwards, or the sliding rod 8 is retracted into the shrinkage tube 7, thereby reducing the volume of the device and making the device easy to carry. When it is necessary to trim the greenery in the garden, the scissors handles 3 can be rotated through the handle 1 to rotate the cutting blades 10, thereby trimming the greenery. The anti-collision rods 2 are used to prevent the shrinkage tubes 7 from hitting each other and causing damage to the device.

[0029] Refer to Figure 1 and Figure 3 A protective shell 4 for protecting the cutting blade 10 is provided. The protective shell 4 is connected to the rotating ring 5. A fixing plate 12 is fixedly connected to the top side of the protective shell 4. A second threaded rod 13 is rotatably connected inside the front end of the fixing plate 12. A rotating ring 11 is fixedly connected to the right end of the second threaded rod 13. A limiting rod 14 is fixedly connected inside the rear end of the fixing plate 12. A sliding piece 15 is connected between the second threaded rod 13 and the limiting rod 14. One end of the sliding piece 15 is threadedly connected to the outer wall of the second threaded rod 13, and the other end of the sliding piece 15 is slidably connected to the outer wall of the limiting rod 14. Two limiting columns 16 are fixedly connected to the lower right side of the sliding piece 15. Limiting holes are formed on the left side of the rotating ring 5, and the limiting columns 16 are in interference fit in the limiting holes;

[0030] Specifically, when the device is idle, put the protective case 4 on the cutting knife 10, and then rotate the rotating ring 11, so that the second threaded rod 13 rotates, so that the sliding piece 15 moves left and right, so as to drive the limiting column 16 to move left and right, so that the limiting column 16 is inserted into the limiting hole, so as to install the protective case 4 on the rotating ring 5, so as to protect the cutting knife 10, so as to prevent the device from being damaged and prevent the device from hurting people when it is idle.

[0031] Working principle: Rotate the rotating ring 5 to make the first threaded rod 18 rotate, so that the sliding rod 8 slides in the contraction tube 7 under the restriction of the limiting strip 17, so as to push the handle 1 outwards, or contract the sliding rod 8 into the contraction tube 7, so as to reduce the volume of the device. When it is necessary to prune the greening of the garden, the cutting knife handle 3 can be rotated through the handle 1 to make the cutting knife 10 rotate, so as to prune the greening. The anti-collision rod 2 is used to prevent the contraction tubes 7 from hitting each other and causing damage to the device. When the device is idle, put the protective case 4 on the cutting knife 10, and then rotate the rotating ring 11, so that the second threaded rod 13 rotates, so that the sliding piece 15 moves left and right, so as to drive the limiting column 16 to move left and right, so that the limiting column 16 is inserted into the limiting hole, so as to install the protective case 4 on the rotating ring 5, so as to protect the cutting knife 10.
