Technical Field

[0001] This utility model relates to the field of pruning device technology, specifically to a dead branch pruning device for landscaping. Background Technology

[0002] In the process of garden and greening maintenance, it is often necessary to prune dead branches to avoid affecting the overall aesthetics of the vegetation. At the same time, pruning dead branches can improve the growth of vegetation and promote photosynthesis.

[0003] A search revealed a patent in Chinese Patent Publication No. CN215011814U entitled "A garden greening maintenance dead branch pruning device, comprising: a first pruning shear body, a second pruning shear body of the same size installed on the outside of the first pruning shear body, and a connecting rod installed through the interior of both the second pruning shear body and the first pruning shear body, forming an "X" shaped structure between the right ends of the first pruning shear body and the second pruning shear body, and forming a rotating structure between the second pruning shear body and the first pruning shear body through the connecting rod."

[0004] The aforementioned patent mainly uses the opposing rotation of the first and second pruning shear bodies to prune dead branches. However, for some thicker dead branches, the shear stress of the first and second pruning shear bodies cannot cut them off, and a saw blade is generally needed to cut them off. This makes it necessary to use multiple tools to complete the pruning of dead branches, and the pruning process is troublesome. In view of this, this utility model proposes a dead branch pruning device for landscaping. Utility Model Content

[0005] This utility model proposes a dead branch pruning device for landscaping, which solves the problem in the prior art that thicker dead branches cannot be pruned with scissors.

[0006] The technical solution of this utility model is as follows: A pruning device for dead branches in landscaping includes a protective sleeve. A pruning mechanism is provided on the inner side of the protective sleeve. The pruning mechanism includes a first shear plate. One end of the first shear plate is rotatably connected to a connecting shaft that passes through the first shear plate. The bottom end of the connecting shaft is rotatably connected to a second shear plate that is offset from the first shear plate. A serrated strip is fixedly connected to the opposite ends of the first and second shear plates. A handle is fixedly connected to the same end of the first and second shear plates. A locking component for limiting the rotation of the handle is provided between the two handles. An anti-detachment component that slides with the connecting shaft is provided on the outer side of the protective sleeve.

[0007] Preferably, the connecting shaft has a through hollow structure inside, and the vertical cross-section of the connecting shaft is a T-shaped structure.

[0008] Preferably, the locking assembly includes a rotating rod, one end of which is rotatably connected to one of the grips via a pin. A torsion spring is sleeved on the pin of the rotating rod, one end of which is welded to the rotating rod, and the other end of which is welded to the rotating rod. A slot is provided at the other end of the rotating rod, and a limiting member that slides with the slot is provided on the other grip.

[0009] Preferably, the limiting member includes a limiting rod that passes through the grip, the limiting rod being slidably connected to the grip, one end of the limiting rod being slidably engaged with a slot, and the other end of the limiting rod being fixedly connected to a first pull block.

[0010] Preferably, the limiting member further includes a first stop block fixedly connected to the middle of the limiting rod, the grip rod is provided with a first clearance groove that slides with the first stop block, the limiting rod is fitted with a first spring, one end of the first spring abuts against the first stop block, and the other end of the first spring abuts against the inner wall of the first clearance groove.

[0011] Preferably, the anti-detachment component includes a positioning rod penetrating the side wall of the protective sleeve, the positioning rod being slidably connected to the side wall of the protective sleeve, one end of the positioning rod being slidably engaged with a connecting shaft, and the other end of the positioning rod being fixedly connected to a second pull block.

[0014] The working principle and beneficial effects of this utility model are as follows: When pruning thinner dead branches, the first and second shear plates can be rotated in opposite directions by operating the two handles. This allows the first and second shear plates to simultaneously apply shear stress to the dead branches and cut them off. When pruning thicker dead branches, the first and second shear plates are combined, and the rotation of the handles is restricted by the locking component. Then, the serrated strip on the back of the first or second shear plate is placed on the dead branch. By pulling the handles back and forth, the serrated strip slides back and forth and cuts off the dead branch. The entire structure can realize corresponding pruning methods for dead branches of different thicknesses. It is simple to operate and helps to improve the pruning efficiency of dead branches.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-5 As shown, this embodiment proposes a pruning device for landscaping, including a protective sleeve 1. A pruning mechanism 2 is provided on the inner side of the protective sleeve 1. The pruning mechanism 2 includes a first shear plate 21. One end of the first shear plate 21 is rotatably connected to a connecting shaft 23 that passes through the first shear plate 21. The connecting shaft 23 has a hollow structure inside and a T-shaped vertical cross-section. The bottom end of the connecting shaft 23 is rotatably connected to a second shear plate 22 that is offset from the first shear plate 21. A serrated strip 24 is fixedly connected to the opposite ends of the first shear plate 21 and the second shear plate 22. A handle 25 is fixedly connected to the same end of the first shear plate 21 and the second shear plate 22. A locking component 26 for limiting the rotation of the handle 25 is provided between the two handles 25. An anti-detachment component 27 that slides with the connecting shaft 23 is provided on the outer side of the protective sleeve 1.

[0024] When pruning thinner dead branches, the first shear plate 21 and the second shear plate 22 can be rotated in opposite directions by operating the two handles 25. This allows the first shear plate 21 and the second shear plate 22 to simultaneously apply shear stress to the dead branch and cut it off. When pruning thicker dead branches, the first shear plate 21 and the second shear plate 22 are combined, and the rotation of the handles 25 is restricted by the locking component 26. Then, the serrated strip 24 on the back of the first shear plate 21 or the second shear plate 22 is placed on the dead branch. By pulling the handles 25 back and forth, the serrated strip 24 slides back and forth and cuts off the dead branch. The entire structure can realize the corresponding pruning method for dead branches of different thicknesses. It is simple to operate and helps to improve the pruning efficiency of dead branches.

[0025] Furthermore, the locking assembly 26 includes a rotating rod 261. One end of the rotating rod 261 is rotatably connected to one of the grips 25 via a pin. A torsion spring 262 is sleeved on the pin of the rotating rod 261. One end of the torsion spring 262 is welded to the rotating rod 261, and the other end of the torsion spring 262 is welded to the rotating rod 261. A slot 264 is provided at the other end of the rotating rod 261. A limiting member 263 is provided on the other grip 25, which slides in cooperation with the slot 264. The limiting member 263 includes a limiting rod 2631 that passes through the grip 25. The limiting rod 2631 and the grip 25 are connected in a sliding manner. 5. Sliding connection: one end of the limiting rod 2631 is slidably engaged with the slot 264, the other end of the limiting rod 2631 is fixedly connected to the first pull block 2632, the middle part of the limiting rod 2631 is fixedly connected to the first stop block 2633, the grip rod 25 is provided with a first clearance groove 2634 that is slidably engaged with the first stop block 2633, and a first spring 2635 is sleeved on the limiting rod 2631. One end of the first spring 2635 abuts against the first stop block 2633, and the other end of the first spring 2635 abuts against the inner wall of the first clearance groove 2634.

[0026] When the serrated blade 24 is needed, the first shear plate 21 and the second shear plate 22 are combined by operating the handle 25. Then, the first pull block 2632 is pulled down to make the limiting rod 2631 slide down, so that the first stop block 2633 slides completely into the first clearance groove 2634. At this time, the first spring 2635 is compressed and accumulates potential energy. Then, the rotating rod 261 is rotated to make the slot 264 move directly above the limiting rod 2631. Then, the first pull block 2632 is released to make the first spring 2635 release potential energy, so that the limiting rod 2631 slides upward and cooperates with the slot 264. This prevents the two handles 25 from opening, so that the first shear plate 21 and the second shear plate 22 can be kept in a stable combined state, and the serrated blade 24 can be used to prune dead branches.

[0027] When the first shear plate 21 and the second shear plate 22 are needed, the first pull block 2632 is pulled down to make the limiting rod 2631 slide down and disengage from the slot 264. At the same time, the rotating rod 261 slides in the opposite direction under the action of the torsion spring 262. At this time, the grip rod 25 can be opened freely. Then, by operating the two grip rods 25, the first shear plate 21 and the second shear plate 22 can rotate in opposite directions. This allows the first shear plate 21 and the second shear plate 22 to apply shear stress to the dead branches at the same time and cut them off. The whole structure can realize two pruning methods, making the operation more convenient.

[0028] Furthermore, the anti-detachment component 27 includes a positioning rod 271 that penetrates the side wall of the protective sleeve 1. The positioning rod 271 is slidably connected to the side wall of the protective sleeve 1. The positioning rod 271 is concentrically arranged with the connecting shaft 23, and the diameter of the positioning rod 271 is smaller than the inner diameter of the connecting shaft 23. One end of the positioning rod 271 is slidably engaged with the connecting shaft 23, and the other end of the positioning rod 271 is fixedly connected to a second pull block 272. A second stop block 273 is fixedly connected to the middle of the positioning rod 271. The inner wall of the protective sleeve 1 is provided with a second clearance groove 274 that slidably engages with the second stop block 273. A second spring 275 is sleeved on the positioning rod 271. One end of the second spring 275 abuts against the second stop block 273, and the other end of the second spring 275 abuts against the inner wall of the second clearance groove 274.

[0029] After use, the first shear plate 21 and the second shear plate 22 are joined together, and the two grips 25 cannot be opened by the limiting rod 2631 and the slot 264. Then, by pulling the second pull block 272 upward, the positioning rod 271 slides upward, causing the second spring 275 to be compressed and accumulate potential energy. Then, the protective sleeve 1 is completely placed on the outside of the first shear plate 21 and the second shear plate 22. At this time, the positioning rod 271 is directly above the connecting shaft 23. Then, the second pull block 272 is released, causing the second spring 275 to release potential energy, causing the positioning rod 271 to move downward and cooperate with the connecting shaft 23. This prevents the protective sleeve 1 from detaching from the first shear plate 21 and the second shear plate 22, thereby enabling the protective sleeve 1 to provide stable protection and preventing the first shear plate 21 and the second shear plate 22 from causing injury to the user.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
