Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree pruning tools, and more specifically, to a retractable fruit tree pruning tool. Background Art

[0002] With the progress of modern society, people pay more and more attention to the balanced collocation of nutrition. Eating fresh fruits every day has almost become a necessity for people, just like three meals a day. All kinds of fruits are obtained by fruit farmers through their own hard work and sweat in managing orchards. In orchard management, in addition to daily management such as fertilizing, watering, and weeding, regular pruning of fruit trees is also an essential management task;

[0003] After retrieval, the existing patent (publication number: CN213991766U) discloses a fruit tree pruning tool, which includes a bottom plate. A fixed sleeve rod is fixedly installed on the top of the bottom plate. An installation frame is fixedly installed on one side of the fixed sleeve rod. A solar charging panel is fixedly installed on the side of the installation frame away from the fixed sleeve rod. A telescopic inner rod is movably installed inside the fixed sleeve rod. A pruning box is fixedly installed on the top of the telescopic inner rod. A movable frame is fixedly installed on one side of the pruning box. An extension frame is movably installed inside the movable frame. A lifting telescopic rod is movably installed at the bottom of the extension frame. By starting the installed lifting telescopic rod, the extension frame can be lifted, so that it is convenient to place the storage bag under the fruits or branches and leaves. Then, by using the installed pruning pliers to cut off the fruits or branches and leaves, the fruits or branches and leaves can fall into the storage bag of the device, avoiding damage to the fruits and fruit trees, ensuring the quality of fruit products. At the same time, after pruning the branches and leaves, they can be collected and processed together, reducing the problem of later cleaning;

[0004] However, there are still some deficiencies in the above solution. During the use of the fruit tree pruning tool, the user holds the pruning tool by hand to prune the fruit tree. Excessive parts installed on the pruning tool will increase the weight of the pruning tool. When the staff holds the pruning tool to prune the fruit branches and leaves at high places, the burden on the arm is too heavy, resulting in arm shaking, which affects the accuracy of pruning. At the same time, holding a relatively heavy pruning tool for a long time will also cause the arm to be over-fatigued and injured.

[0005] In view of this, the utility model provides a retractable fruit tree pruning tool. Content of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a collapsible fruit tree pruner to solve the problems that during the use of a fruit tree pruner, the user holds the pruner by hand to prune the fruit tree. Excessive parts installed on the pruner will increase the weight of the pruner. When the staff holds the pruner to prune the branches and leaves at high places, the burden on the arm is too heavy, resulting in arm shaking, which affects the accuracy of pruning. At the same time, holding a relatively heavy pruner by hand for a long time will also cause the arm to be overworked and injured.

[0016] In the present utility model, by providing a movable inner rod and a pruning assembly, using the above structure, equidistant circular holes are provided on the surface of the movable inner rod. When the telescopic movable inner rod is extended and the groove is aligned with the circular hole, the block pops out under the elastic force of the first spring, thereby fixing the position of the movable inner rod inside the fixed rod housing. When pruning fruit trees, pruning is performed on the fruit trees through the pruning knife and the cutting block, achieving the effect that the movable inner rod can be telescoped and is convenient for storage.

[0017] In the present utility model, by providing a control assembly, using the above structure, during pruning, when the control handle is pressed, the control handle rotates to drive the rope sleeve to move. The connecting rope is connected between the rope sleeve and the pruning knife. When the control handle is pressed, the pruning knife is pulled to shear with the cutting block. After releasing the control handle, the pruning knife is pulled back by the elastic force of the second spring, avoiding the wear of the connecting rope by the movable inner rod. The connecting rope slides on the sliding rod, reducing the friction with the movable inner rod, achieving the effect that pruning of fruit trees can be performed on the ground.

The rope member 43 includes a rope sleeve 431 and a connecting rope 432. One end of the rope sleeve 431 is fixedly installed at one end of the control handle 411, and the other end is fixedly connected to the inside of the rotating handle 422. One end of the connecting rope 432 is fixedly connected to the surface of the rope sleeve 431, and the other end is fixedly connected to the side of the pruning knife 311 away from the contraction member 32.

[0030] Specifically, during pruning, press the control handle 411. The rotation of the control handle 411 drives the rope sleeve 431 to move. The connecting rope 432 is connected between the rope sleeve 431 and the pruning knife 311. When pressing the control handle 411, the pruning knife 311 is pulled to shear with the cutting block 34. After releasing the control handle 411, the elastic force of the second spring 322 pulls the pruning knife 311 back, avoiding the wear of the connecting rope 432 by the moving inner rod 2. The connecting rope 432 slides on the sliding rod 332, reducing the friction with the moving inner rod 2.

[0031] The working process of the present utility model is as follows:

[0032] Equidistant circular holes 21 are provided on the surface of the moving inner rod 2. When the telescopic moving inner rod 2 is extended and the groove 12 is opposite to the circular hole 21, the clamping block 132 pops out under the elastic force of the first spring 131, thereby fixing the position of the moving inner rod 2 inside the fixed rod housing 1. When pruning fruit trees, the fruit trees are pruned by the pruning knife 311 and the cutting block 34. During pruning, press the control handle 411. The rotation of the control handle 411 drives the rope sleeve 431 to move. The connecting rope 432 is connected between the rope sleeve 431 and the pruning knife 311. When pressing the control handle 411, the pruning knife 311 is pulled to shear with the cutting block 34. After releasing the control handle 411, the elastic force of the second spring 322 pulls the pruning knife 311 back, avoiding the wear of the connecting rope 432 by the moving inner rod 2. The connecting rope 432 slides on the sliding rod 332, reducing the friction with the moving inner rod 2.
