Description

Technical Field

[0001] This utility model relates to the field of tree branch pruning technology, and in particular to a fruit tree pruning device. Background Technology

[0002] In the process of fruit tree planting and management, pruning is a key link in regulating the growth of fruit trees and improving fruit yield and quality. Its core objective is to optimize the canopy structure of fruit trees by removing diseased, weak, crossing, and overly dense branches, ensuring ventilation and light penetration, and guiding nutrients to concentrate on fruiting branches.

[0003] In existing technologies, fruit tree pruning operations mainly rely on manual labor using tools such as pruning shears and saws. When using pruning shears, it is generally only convenient to prune lower branches. When it is necessary to prune higher branches, a ladder is required to help workers climb up. Every time the pruning position is moved, the ladder needs to be moved, which is very inconvenient. Therefore, a fruit tree pruning device has been designed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fruit tree pruning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fruit tree pruning device includes an extension rod and a fixed handle. The fixed handle has a rectangular slot at its bottom and a fixed blade fixedly connected to its top. A rotating handle is rotatably connected to one side of the fixed handle via a pivot, and a rotating blade is fixedly connected to its top. A connecting hole is located at the bottom of the rotating handle. Two sliding rods are fixedly connected to the outer wall of the fixed handle away from the rotating handle. A limit block is fixedly connected to the other end of each sliding rod. A T-shaped insert is slidably fitted onto the circumferential surface of both sliding rods. Both ends of the T-shaped insert have round holes adapted to the sliding rods, and the T-shaped insert slides through the fixed handle and communicates with the rectangular slot. Springs are fitted onto the circumferential surface of both sliding rods between the T-shaped insert and the limit block. A pull rod is fixedly connected to the outer side of the T-shaped insert. The T-shaped insert, pull rod, and limit block ensure that the fixed handle will not detach during operation when connected to the extension rod, improving operational stability.

[0006] Preferably, the top of the extension rod is fixedly connected to a plug plate, and the plug plate is adapted to the rectangular slot, and the top of the plug plate is provided with a plug hole, which is adapted to the T-shaped plug rod.

[0007] Preferably, a square rod is slidably sleeved in the middle of the extension rod, and a square hole adapted to the square rod is opened in the middle of the extension rod. A first side groove is opened on the top of the extension rod on one side of the square rod. The rotating blade and the fixed blade can work by the up and down movement of the square rod and the pushing of the L-shaped connecting rod.

[0008] Preferably, an L-shaped connecting rod is rotatably connected to the top of the square rod near the first side groove, and the other end of the L-shaped connecting rod is adapted to the connecting hole.

[0009] Preferably, the bottom of the extended rod has a second side groove, and a connecting rod is rotatably connected to the bottom of the square rod near the second side groove.

[0010] Preferably, a fixing ring is fixedly sleeved at the bottom of the extension rod, and a pull rod is rotatably connected to the side of the fixing ring near the connecting rod. The other end of the connecting rod is rotatably connected to the middle of the pull rod. Through the cooperation of the pull rod and the connecting rod, the square rod can be moved when the pull rod is turned, thereby realizing the movement of the fixed blade and the rotating blade.

[0011] Preferably, the outer circumference of the extension rod near the bottom is fixedly fitted with an anti-slip sleeve.

[0012] The beneficial effects of this utility model are as follows: By employing technologies such as pull rods, connecting rods, square rods, plug-in plates, T-shaped plugs, and springs, the fixed handle and extension rod can be quickly separated or connected by the movement of the T-shaped plug. This makes the device suitable for pruning branches at both low and high locations, improving flexibility and effectively solving the problem of pruning shears being inconvenient for pruning branches at high locations, as mentioned in the background technology. It thus meets the pruning needs of both low and high locations, and height switching can be completed without replacing the entire set of equipment. This significantly improves the adaptability of a single device, increases overall pruning efficiency, and avoids the cost of purchasing additional special tools due to the single function of the equipment, thus balancing practicality and economy.

The fixed handle 3 has a rectangular slot 301 at its bottom, and a fixed blade 302 is fixedly connected to its top. A rotating handle 4 is rotatably connected to one side of the middle of the fixed handle 3 via a pivot. A rotating blade 401 is fixedly connected to the top of the rotating handle 4, and a connecting hole 402 is provided at the bottom of the rotating handle 4. Two sliding rods 5 are fixedly connected to the outer wall of the fixed handle 3 away from the rotating handle 4. Limit blocks 502 are fixedly connected to the other ends of both sliding rods 5. The same T-shaped insert 503 is slidably fitted on the surface. Both ends of the T-shaped insert 503 are provided with round holes that are compatible with the slide rod 5. The T-shaped insert 503 slides through the fixed handle 3 and connects with the rectangular slot 301. Springs 501 are fitted on the circumferential surfaces of the two slide rods 5 located between the T-shaped insert 503 and the limiting block 502. A pull rod 504 is fixedly connected to the outside of the T-shaped insert 503. Through the setting of springs 501, T-shaped insert 503 and pull rod 504, the connection between the fixed handle 3 and the plug plate 7 is very stable.

[0017] In this utility model, the top of the extension rod 1 is fixedly connected to a plug plate 7, and the plug plate 7 is adapted to the rectangular slot 301. The top of the plug plate 7 is provided with a plug hole 701, and the plug hole 701 is adapted to the T-shaped plug rod 503. The cooperation between the plug plate 7 and the rectangular slot 301 can realize the stable connection between the fixed handle 3 and the extension rod 1.

[0018] In this utility model, a square rod 6 is slidably sleeved in the middle of the extension rod 1, a square hole adapted to the square rod 6 is opened in the middle of the extension rod 1, and a first side groove 101 is opened on the top of the extension rod 1 on one side of the square rod 6.

[0019] In this utility model, an L-shaped connecting rod 601 is rotatably connected to the top of the square rod 6 near the first side groove 101, and the other end of the L-shaped connecting rod 601 is adapted to the connecting hole 402.

[0020] In this utility model, the bottom of the extended rod 1 is provided with a second side groove 102, and the bottom of the square rod 6 is rotatably connected to the side of the second side groove 102.

[0021] In this utility model, a fixing ring 8 is fixedly sleeved at the bottom of the extension rod 1, and a pull rod 801 is rotatably connected to the side of the fixing ring 8 near the connecting rod 802. The other end of the connecting rod 802 is rotatably connected to the middle of the pull rod 801. By pulling the pull rod 801 downward, the rotating blade 401 and the fixed blade 302 can be brought closer to each other to achieve the pruning of branches.

[0022] In this utility model, an anti-slip sleeve 2 is fixedly sleeved on the outer circumference of the extension rod 1 near the bottom. The anti-slip sleeve 2 can improve the anti-slip ability of the extension rod 1 and improve the user experience.

[0023] Working principle: When using this pruning device, if the pruning position is low, the fixed handle 3 can be directly separated from the extension rod 1. The user can hold the fixed handle 3 and the rotating handle 4 to prune low branches. When the fixed handle 3 and the rotating handle 4 are brought close together, the fixed blade 302 will approach the rotating blade 401 to cut the branch. When pruning high branches, the user cannot reach the branches by holding the fixed handle 3. In this case, the extension rod 1 can be used to extend the branch. The fixed handle 3 and the rotating handle 4 are brought close together and moved to the top of the extension rod 1. The top of the L-shaped connecting rod 601 is inserted into the connecting hole 402, the rectangular slot 301 is inserted into the plug plate 7, and the pulling rod 504 is pulled. This allows the T-shaped insert 503 to leave the rectangular slot 301, allowing the insert plate 7 to be fully inserted into the rectangular slot 301. Then, releasing the pull rod 504 allows the pull rod 504 to be inserted into the insertion hole 701, thus achieving a stable connection between the fixed handle 3 and the extension rod 1. In use, the user only needs to pull the pull rod 801 downwards, causing the connecting rod 802 to slide down with the square rod 6. As the square rod 6 moves downwards, the L-shaped connecting rod 601 at the top of the square rod 6 will pull the rotating handle 4 closer to the fixed handle 3, allowing the rotating blade 401 to approach the fixed blade 302 for cutting. By repeatedly pulling the pull rod 801 and resetting it, continuous work can be achieved. In this way, the user can prune branches at high places without the need for a ladder.
