[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-3 The utility model provides an embodiment of a device for pruning fruit tree branches at a fixed height, comprising a base 1, a first fixing rod 2 being fixedly connected to the top of the base 1, a connecting shell 3 being fixedly connected to one side of the first fixing rod 2, a connecting rod 5 being rotatably connected to the inside of the connecting shell 3, one end of the connecting rod 5 being fixedly connected to a first bevel gear 6, the inside of the first fixing rod 2 being rotatably connected to a rotating rod 7, the outside of the rotating rod 7 being fixedly connected to a second bevel gear 8, one end of the rotating rod 7 being fixedly connected to a sleeve rod 9, the outside of the sleeve rod 9 being fixedly connected to a rotating column 10, the top of the first fixing rod 2 being fixedly connected to a connecting tube 11, one end of the sleeve rod 9 being rotatably connected to a rotating shaft 12, an extension assembly being installed on the top of the sleeve rod 9, and the extension assembly being used to extend the pruning knife 19.

[0025] Specifically, the base 1 serves as the supporting foundation of the entire device, ensuring the stability and verticality of the first fixed rod 2. At the same time, the wheels at the bottom of the base 1 can facilitate the operator to push the entire device back to the storage area after pruning is completed. By rotating the handle 4 outside the connecting shell 3, the rotation of the connecting rod 5 can be directly transmitted to the first bevel gear 6, thereby driving it to rotate, and then driving the second bevel gear 8 to rotate together, and the rotational force is transmitted to the sleeve rod 9 through the rotating rod 7. At the same time, the connecting tube 11 provides support for the rotation of the sleeve rod 9, and then allows the rotating column 10 to rotate inside the groove, ensuring that the sleeve rod 9 can rotate at multiple angles.

[0026] Reference Figure 2-4The extension assembly includes a movable cylinder 13, the outside of the movable cylinder 13 is fixedly connected to the inside of the rotating shaft 12, a cavity 20 is opened inside the movable cylinder 13, a rack plate 16 is slidably connected inside the cavity 20, one end of the rack plate 16 is fixedly connected to a connecting column 17, the outside of the connecting column 17 is fixedly connected to a sliding rod 18, one end of the sliding rod 18 is fixedly connected to a trimming knife 19, the inside of the cavity 20 is rotatably connected to a rotating gear 15, and the outside of the rotating gear 15 is rotatably connected to the second fixed rod 14.

[0027] Specifically, the movable cylinder 13 can swing in the horizontal direction through the rotating shaft 12. At the same time, the cavity 20 inside the movable cylinder 13 drives the rack plate 16 to slide in the cavity 20 when the rotating gear 15 rotates. The sliding of the rack plate 16 can be directly transmitted to the slide rod 18 through the connecting column 17, so that the slide rod 18 directly drives the trimming knife 19 to extend. Through the rotation of the second fixed rod 14, the rotating gear 15 is kept in a fixed position and rotates.

[0028] Reference Figure 3 The outside of the first bevel gear 6 is rotatably connected to the inside of the first fixed rod 2, and the corresponding position of the outside of the first bevel gear 6 is meshed with the outside of the second bevel gear 8. One end of the connecting rod 5 extends to the outside of the connecting shell 3 and is fixedly connected to the handle 4. A groove is opened inside the connecting tube 11, and the outside of the rotating column 10 is rotatably connected inside the groove.

[0029] Specifically, the first bevel gear 6 rotates inside the first fixed rod 2 and can effectively engage and transmit with the second bevel gear 8. The operator can drive the connecting rod 5 to rotate by rotating the handle 4, and the rotating column 10 rotates in the groove in the connecting cylinder 11, so that the sleeve rod 9 can rotate steadily.

[0030] Reference Figure 4 The outside of the rack plate 16 is meshed with the outside of the rotating gear 15, the outside of the slide rod 18 is slidably connected to the inside of the cavity 20, one end of the second fixed rod 14 extends to the outside of the movable cylinder 13 and is fixedly connected to a handle 21, one end of the movable cylinder 13 is fixedly connected to a hand-held rod 22, the outside of the first fixed rod 2 is fixedly connected to a bracket 23, and the bottom of the bracket 23 is fixedly connected to the top of the base 1.

[0031] Specifically, when the rotating gear 15 rotates, it can drive the rack plate 16 to slide along its length direction in the cavity 20. This sliding movement is then transmitted to the pruning knife 19 through the connecting column 17 and the slide rod 18, realizing its extension and shortening function. The cavity 20 further limits the moving direction of the slide rod 18 so that it can only move along the length direction of the cavity 20. The handle 21 serves as a structure that facilitates the operator to control the extension of the slide rod 18 and can be adjusted by rotation.

[0032] Working principle: First, the operator moves the device to the position where the fruit tree needs to be pruned through the base 1, and then operates the handle 4 to rotate the connecting rod 5. The rotation of the connecting rod 5 drives the first bevel gear 6 to rotate. Since the first bevel gear 6 is meshed with the second bevel gear 8, the second bevel gear 8 is also driven to rotate. When the second bevel gear 8 rotates, the rotating rod 7 rotates, and at the same time drives the sleeve rod 9 to rotate, so that the connecting tube 11 rotates inside the groove, and then the fruit tree can be pruned in all directions.

[0033] Secondly, the operator holds the handle bar 22 and then moves the movable cylinder 13 to align the pruning knife 19 with the branch that needs to be pruned. Since the branches of the fruit trees are of different heights, when pruning branches of different heights neatly, the handle 21 is rotated, and then the second fixed rod 14 drives the rotating gear 15 to rotate, and through the meshing relationship between the rotating gear 15 and the rack plate 16, the rotation of the rotating gear 15 drives the rack plate 16 to slide inside the cavity 20. The sliding of the rack plate 16 is converted into a linear motion of the slide bar 18 through the connecting column 17, thereby driving the pruning knife 19 to extend outward, and then it is convenient for the operator to prune higher branches. In addition, when the pruning knife 19 needs to be shortened, the handle 21 is rotated in the opposite direction to make the rotating gear 15 rotate in the opposite direction, thereby driving the rack plate 16 and the slide bar 18 to slide into the cavity 20, so that the pruning knife 19 is retracted to its initial length.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
