Description

Technical Field

[0001] This utility model belongs to the field of fruit tree branch pruning technology, and in particular relates to a multi-functional tool for pruning fruit tree branches. Background Technology

[0002] Pruning fruit tree branches is an important part of fruit tree cultivation and management. Proper pruning can promote the healthy growth of fruit trees, increase yield, and improve fruit quality.

[0003] According to a public announcement (publication number: CN222442416U), a multifunctional dwarf rootstock fruit tree pruning tool includes a box body with a lid hinged at the bottom. The box body has a protective pad inside, and the protective pad has multiple through holes. One of the through holes is equipped with pruning shears. The pruning shears have cutting teeth on one side, a pruning mechanism on the other side, and an auxiliary mechanism inside the through hole on the other side.

[0004] In the aforementioned application, through the cooperation of the pruning shears and auxiliary mechanism components, when workers prune fruit tree branches, if they encounter situations beyond the tool's working range, it is often difficult to resolve the issue using simple telescopic functions. In such cases, workers may need to climb to the top of the tree to carry out the pruning work, which not only increases the difficulty of the work but also greatly increases the safety risk and may lead to accidents. Therefore, we propose a multi-functional tool for pruning fruit tree branches. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional tool for pruning fruit tree branches. By designing components such as gears, racks, and anti-return claws in the adjustment mechanism, it solves the problems of difficult adjustment of telescopic rods and inconvenience of pruning at heights in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a multi-functional tool for pruning fruit tree branches, including a base rod, a telescopic rod slidably connected inside the base rod, a rotating pruning shear connected to the top of the telescopic rod, a fixed pruning shear fixedly connected to the top of the telescopic rod, cutting teeth fixedly connected to the side of the fixed pruning shear, and an adjustment mechanism provided inside the base rod. The adjustment mechanism includes an operating box, which is fixedly connected to the circumferential surface of the base rod. A control shaft is rotatably connected through the side of the operating box. A gear is fixedly connected to one end of the control shaft that passes through the operating box. An installation groove is formed on the circumferential surface of the telescopic rod. A rack is fixedly connected inside the installation groove. The gear and rack mesh with each other. A handle is fixedly connected to the end of the control shaft away from the operating box. A rotating shaft is rotatably connected inside the operating box. A check pawl is fixedly connected to the circumferential surface of the rotating shaft. A limiting rod is fixedly connected inside the operating box. The purpose is to facilitate users to adjust the length according to the height of the tree, avoid climbing the tree, and improve work efficiency and safety.

[0007] Furthermore, a reset spring is fixedly connected inside the operating box. The end of the reset spring away from the inside of the operating box is fixedly connected to the side of the check pawl. The purpose of this is to ensure that the check pawl can automatically reset and reduce manual intervention.

[0008] Furthermore, a tension spring is fixedly connected inside the base rod, and one end of the tension spring away from the inside of the base rod is fixedly connected to the bottom of the rack. The purpose of this is to ensure that the rack can automatically reset when the gear leaves the meshing area of ​​the rack, thereby reducing manual intervention.

[0009] Furthermore, the check pawl is located on the displacement trajectory of the gear, and a locking pin is inserted into the circumferential surface of the control shaft. The purpose of this is to ensure that the rotation of the gear can push the check pawl, and the locking pin prevents the control shaft from sliding.

[0010] Furthermore, a resistance mechanism is provided inside the base rod. The resistance mechanism includes a rubber block, which is fixedly connected inside the mounting groove. A support shaft is rotatably connected inside the base rod. A resistance block is fixedly connected to the circumferential surface of the support shaft. A limiting arc block is fixedly connected inside the base rod. The purpose of this is to prevent the telescopic rod from retracting too quickly, which could cause danger to the rotating and fixed trimmers.

[0011] Furthermore, a torsion spring is fixedly connected inside the base rod, and one end of the torsion spring away from the inside of the base rod is fixedly connected to the circumferential surface of the support shaft. The purpose of this is to ensure that the resistance block can automatically reset and reduce manual intervention.

[0012] Furthermore, the number of rubber blocks, resistance blocks, and torsion springs is set to several, and they are arranged in a linear array inside the mounting groove. The resistance blocks are located on the displacement trajectory of the rubber blocks, the purpose of which is to ensure that the movement of the rubber blocks can push the resistance blocks.

[0013] This utility model has the following beneficial effects: This invention utilizes the interplay between components such as gears, racks, and check pawls in an adjusting mechanism. When a worker uses a base rod to drive rotating and fixed pruning shears for trimming, and encounters high branches, the worker can rotate the control shaft by gripping the handle. The control shaft drives the gear to rotate, and the gear meshes with the rack, causing the telescopic rod to extend upwards and move the pruning shears. As the gear rotates, it pushes the check pawl, which is then reset to the gear's tooth area via the rotating shaft and a return spring. A limiting rod prevents rotation, ensuring stable trimming. After trimming, the locking pin is pulled out, the control shaft moves, the rack resets under the action of the tension spring, and the telescopic rod returns to its initial state. This design optimizes the efficiency and safety of high-altitude trimming, avoiding the risks associated with workers climbing trees.

[0014] This invention utilizes the interplay between components such as the rubber block, resistance block, and limiting arc block in the resistance mechanism. When the telescopic rod extends, the rubber block pushes the resistance block to rotate, making it unresisted. After rotation, the resistance block is reset by a torsion spring. When the telescopic rod resets, the rubber block pushes the resistance block again, and the limiting arc block restricts the movement of the resistance block. The rubber block contacts and compresses to slow down the movement, preventing the telescopic rod from retracting too quickly and avoiding danger to workers from the scissors. This design improves safety and avoids dangerous operations.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

An installation groove 64 is provided on the circumferential surface of the telescopic rod 2. A rack 65 is fixedly connected inside the installation groove 64. The gear 63 and the rack 65 mesh with each other. A handle 66 is fixedly connected to the end of the control shaft 62 away from the operation box 61. A rotating shaft 67 is rotatably connected inside the operation box 61. A check pawl 68 is fixedly connected to the circumferential surface of the rotating shaft 67. A limiting rod 69 is fixedly connected inside the operation box 61. The purpose of this mechanism is to facilitate users to adjust the length according to the height of the tree, avoid climbing the tree, and improve work efficiency and safety.

[0021] As shown in the figure, a reset spring 610 is fixedly connected inside the operating box 61. The end of the reset spring 610 away from the inside of the operating box 61 is fixedly connected to the side of the check claw 68. The purpose is to ensure that the check claw 68 can automatically reset and reduce manual intervention.

[0022] As shown in the figure, a tension spring 611 is fixedly connected inside the base rod 1. One end of the tension spring 611 away from the inside of the base rod 1 is fixedly connected to the bottom of the rack 65. The purpose is to ensure that the rack 65 can automatically reset when the gear 63 leaves the meshing area of ​​the rack 65, reducing manual intervention.

[0023] As shown in the figure, the check pawl 68 is located on the displacement trajectory of the gear 63, and a locking pin 612 is inserted into the circumferential surface of the control shaft 62. The purpose of this is to ensure that the rotation of the gear 63 can push the check pawl 68, and the locking pin 612 prevents the control shaft 62 from sliding.

[0024] As shown in the figure, the base rod 1 is equipped with a resistance mechanism 7, which includes a rubber block 71. The rubber block 71 is fixedly connected to the inside of the mounting groove 64. The base rod 1 is rotatably connected to a support shaft 72. The circumferential surface of the support shaft 72 is fixedly connected to a resistance block 73. The base rod 1 is also fixedly connected to a limiting arc block 74. The purpose of this is to prevent the telescopic rod 2 from retracting too quickly, which could cause the rotating trimmer 3 and the fixed trimmer 4 to become dangerous.

[0025] As shown in the figure, a torsion spring 75 is fixedly connected inside the base rod 1. One end of the torsion spring 75 away from the inside of the base rod 1 is fixedly connected to the circumferential surface of the support shaft 72. The purpose of this is to ensure that the resistance block 73 can automatically reset and reduce manual intervention.

[0026] As shown in the figure, there are several rubber blocks 71, resistance blocks 73 and torsion springs 75, which are arranged in a linear array inside the mounting groove 64. The resistance block 73 is located on the displacement trajectory of the rubber block 71, and its purpose is to ensure that the movement of the rubber block 71 can push the resistance block 73.

[0027] A specific application of this embodiment is as follows: When a worker uses the base rod 1 to drive the rotating pruning shears 3 and the fixed pruning shears 4 to prune fruit tree branches, and encounters high branches, the worker can rotate the control shaft 62 by holding the handle 66. The rotation of the control shaft 62 drives the gear 63 to rotate. Through the meshing of the gear 63 and the rack 65, the rotation of the gear 63 drives the telescopic rod 2 to extend upwards and out of the base rod 1. The movement of the telescopic rod 2 then drives the rotating pruning shears 3 and the fixed pruning shears 4 to move, adjusting the length according to the height of the tree. During the rotation of the gear 63, a check valve is installed. The claw 68 is pushed, and the check claw 68 is rotated through the rotating shaft 67. After rotation, the check claw 68 is reset to the tooth area of ​​the gear 63 by the return spring 610. The gear 63 is stopped by the limiting rod 69 to prevent rotation. At this time, the staff can prune the branches. After pruning, the staff can pull out the locking pin 612 to move the control shaft 62 and press it into the operation box 61, so that the gear 63 leaves the moving area of ​​the rack 65. At this time, the rack 65 is reset by the elasticity of the tension spring 611, and the telescopic rod 2 returns to its initial state.

[0028] During the extension of the telescopic rod 2, the rubber block 71 pushes the resistance block 73. The resistance block 73 rotates through the support shaft 72 under force, so that the telescopic rod 2 extends without resistance. After rotation, the resistance block 73 is reset by the torsion spring 75. When the telescopic rod 2 resets, it drives the rubber block 71 to move and push the resistance block 73. At this time, the resistance block 73 is restricted by the limiting arc block 74, so that the resistance block 73 is decelerated by contact and compression through the rubber block 71, preventing the telescopic rod 2 from retracting too quickly and causing danger to the workers by rotating the trimmer 3 and fixing the trimmer 4.
