[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A pruning device for landscaping engineering construction includes a housing 1, a pruning structure 2, a counterweight 3, a winding structure 4, and a limiting structure 5. One end of the pruning structure 2 is located inside the housing 1 and is used in cooperation with the winding structure 4. The other end of the pruning structure 2 is fixedly connected to the counterweight 3. The limiting structure 5 is located on the left side of the housing 1. An opening is provided on the outer side of the housing 1, and a cleaning structure 7 is provided at the upper and lower ends of the opening.

[0029] Specifically, the pruning structure 2 includes a rope 21 and saw teeth 22. One end of the rope 21 is fixedly connected to the side surface of the counterweight 3, and the other end of the rope 21 is fixedly connected to the winding structure 4. The number of the saw teeth 22 is several, and a plurality of saw teeth 22 are evenly distributed in a circular array on the surface of the rope 21, and the branches are sawed off by the friction between the saw teeth 22 and the rope 21.

[0030] Furthermore, the winding structure 4 includes a rotating block 41, a rotating block 42, and a rotating block 43. One end of the rope 21 far from the counterweight 3 is fixedly connected to the surface of the rotating block 41 in a winding manner. One end of the rotating block 41 is rotatably connected to the inside of the housing 1, and the other end of the rotating block 41 penetrates to the outside of the housing 1 and is fixedly connected to the rotating block 42. One end of the rotating block 43 is fixedly connected to the outside of the rotating block 42. The rope 21 and the saw teeth 22 are stored inside the housing 1 by winding.

[0031] It should be noted that the limiting structure 5 includes a positioning rod 51 and a sleeve 52. One end of the positioning rod 51 is fixedly connected to the edge of the side surface of the rotating block 42. The surface of the positioning rod 51 is provided with threads. The sleeve 52 is sleeved on the surface of the positioning rod 51 and is threadedly connected. One end of the sleeve 52 contacts the surface of the housing 1. The outer surface of the sleeve 52 is anti-slip treated, which can limit the winding structure 4 and prevent the rope 21 from moving during work or carrying.

[0032] It should be noted that the cleaning structure 7 includes a bracket 71 and a cleaning brush 72. One end of the bracket 71 is fixedly connected to the outside of the housing 1. The cleaning brushes 72 are distributed on the surface of the bracket 71 in an annular array. One end of the rope 21 far from the rotating block 41 penetrates between the opening and two rows of cleaning brushes 72 and is fixedly connected to the counterweight 3. During the winding process, the waste chips of the branches can be cleaned to avoid jamming during winding.

[0033] In addition, a handle 6 is fixedly connected to the side surface of the housing 1 far from the rotating block 43. The handle 6 and the counterweight 3 are oval in shape, which is convenient for the user to operate when pulling the rope 21 back and forth to rub.

[0034] It has to be said that a rotating rod 8 is rotatably connected to the inner side of the opening. The rotating rods 8 are distributed on the upper and lower sides of the rope 21, which plays a guiding role to prevent the position of the rope 21 from deviating during the winding process.

[0035] Working principle: When in use, the user rotates the sleeve 52 so that the sleeve 52 does not contact the housing 1 and the rotating block 42. Then the user pulls out the rope 21 through the counterweight 3. After that, the user throws the rope 21 over the branches through the counterweight 3. After throwing, the user rotates the rotating block 43. The rotation of the rotating block 43 drives the rotation of the rotating block 42, and the rotating block 42 drives the rotation of the rotating block 41. The rotating block 41 winds up the excess rope 21. Then rotate the sleeve 52 again to position it to prevent the rotating block 41 from rotating during the pulling process. Then the user holds the counterweight 3 with one hand and pulls the handle 6 with the other hand to make the rope 21 and the saw teeth 22 rub back and forth on the surface of the branches. When the branch is sawn off, the user winds up the rope 21 through the winding structure 4 for convenient use next time, and the operation is completed.

[0036] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
