[0002] The purpose of fruit tree pruning is to ensure that the fruit tree can make full use of its nutrients, so that it can produce plump fruits. To this end, it is necessary to prune the excess branches of the fruit tree. When pruning fruit tree branches, it is necessary to use fruit tree pruning equipment to cut and separate the excess branches from the fruit tree.

[0003] When using existing fruit tree pruning devices, the user lifts them close to the branch or leaf that needs to be pruned before cutting it. During this process, the user needs to maintain the lifted position for a long time, which can easily cause fatigue. At the same time, during the lowering process, existing fruit tree pruning devices are easily blocked and jammed by other branches. Utility Model Content

[0004] The technical problem that this solution addresses is:

[0005] How can we solve the problems of users having to lift existing fruit tree pruning devices for extended periods, which easily causes fatigue, and the devices being easily blocked or jammed by tree branches?

A blade is fixedly mounted on one end of the L-shaped frame, and the position of the blade corresponds to the position of the L-shaped cutter.

[0008] A further technical improvement of this utility model is that: a lifting frame is provided on one side of the connecting rod, and a pressing wheel is rotatably provided on the top of the lifting frame. The pressing wheel is rolledly connected to the end of the L-shaped frame away from the blade, and the pressing wheel is located above the L-shaped frame.

[0009] A further technical improvement of this utility model is that: the bottom of the L-shaped frame, away from the blade, has a cutting edge for cutting branches and leaves; by using one hand to grasp the fixing ring and lift it, and the other hand to hold the handle, the connecting rod is extended upward, so that the L-shaped cutter reaches the branch and leaves, making it easy for the user to control the rotation rod to rotate, providing downward pressure to the roller, so that the transmission rod, together with the pressing roller, drives the L-shaped frame to rotate, and the blade, together with the L-shaped cutter, prunes the branches and leaves. The user holds the fixing ring and the handle with both hands respectively to ensure the normal operation of the L-shaped cutter and to prevent user fatigue; at the same time, if the connecting rod is stuck by a branch during the process of lowering the L-shaped cutter, the connecting rod is pulled down while controlling the rotation rod to rotate, and the cutting edge at the end of the L-shaped frame, together with the lifting frame, can cut off the obstructing branch, ensuring the safe and efficient use of the fruit tree pruning device.

[0010] A further technical improvement of this utility model is that: a first guide sleeve and a second guide sleeve are fixedly installed in the middle of the connecting rod, the first guide sleeve and the second guide sleeve are arranged vertically, and a transmission rod is movably inserted between the first guide sleeve and the second guide sleeve, and the top end of the transmission rod is fixedly connected to the lifting frame.

[0011] A further technical improvement of this utility model is that: a stop block and a baffle are fixedly connected in the middle of the transmission rod, the stop block is in contact with the bottom of the first guide sleeve, and a thrust spring is elastically provided between the baffle and the second guide sleeve.

[0012] A further technical improvement of this utility model is that: a roller is rotatably provided at the bottom of the transmission rod, the roller is rollingly connected to the other end of the rotating rod, and the roller is located below the rotating rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In use, the user lifts the device by grasping the fixing ring with one hand and holding the handle with the other, extending the connecting rod upwards so that the L-shaped cutter reaches the branches and leaves. This allows the user to control the rotation of the rotating rod, applying downward pressure to the roller. The transmission rod, in conjunction with the pressing wheel, drives the L-shaped frame to rotate, allowing the blade to prune the branches and leaves. The user's use of both hands to hold the fixing ring and the handle ensures the L-shaped cutter operates normally and prevents user fatigue. Furthermore, if the connecting rod gets stuck on a branch while lowering the L-shaped cutter, pulling the connecting rod downwards while controlling the rotation of the rotating rod allows the blade at the end of the L-shaped frame, in conjunction with the lifting frame, to cut off the obstructing branch, ensuring the safe and efficient use of this fruit tree pruning device.
