[0008] Beneficial effects: This invention provides a branch pruning device for apple cultivation. It has the following beneficial effects: (I) This apple planting branch pruning device, by setting up a cutting component with a main cutting blade as the core, and a secondary cutting blade, a protective ring, a main hook and a secondary hook, plays a key role in ensuring normal branch cutting while protecting workers from accidental injury by the blade when not in use. Before and after pruning, the main and secondary cutting blades can be easily closed by moving the position of the protective ring, which plays a protective role, enhances the stability of the cutting component, increases the safety of the blade, prevents accidental injury to workers when not in use, and provides a safe and stable foundation for the pruning process.

[0009] (II) This apple tree pruning device, featuring a telescopic assembly consisting of a rotating shaft, a folding rod, a telescopic rod, locking beads, and locking slots, is the core component of the telescopic pruning device. When folded, the folding rod fits snugly against the handle; when unfolded, the external structure automatically engages. Once the telescopic rod is extended into its final position, it is positioned by the locking beads and locking slots, ensuring overall structural stability and preventing wobbling that could affect the pruning position during use. This flexible adjustment feature allows the device to handle both low-growing tree canopies and the top branches of tall, mature fruit trees, enhancing its versatility and reducing the cost for fruit farmers to purchase multiple pruning devices for trees of different heights. Furthermore, after operation, the telescopic rod can be quickly retracted, and the folding rod can be rotated back to its initial position, restoring the device to a compact form for easy storage and transport in the field, effectively improving orchard management efficiency.

[0011] The present invention will now be described in detail with reference to the accompanying drawings. A branch pruning device for apple cultivation includes: a pruning assembly 1, and a handle 2. The top of the handle 2 is fixedly connected to the bottom of the pruning assembly 1, and a telescopic assembly 3 is rotatably connected to the bottom of the handle 2. The pruning assembly 1 includes a main cutting blade 12. A protective ring 11 is rotatably connected to the top of the main cutting blade 12 via a connecting shaft. The protective ring 11 rotates via a rotating shaft and can engage with a secondary hook 15 on a secondary cutting blade 13. This operation can fix the cut, closing the main and secondary cutting blades together, protecting the blades and preventing accidental injury from the blade tip. The middle of the main cutting blade 12 is rotatably connected to the secondary cutting blade 13 via a connecting shaft. A main hook 14 is fixedly connected to the outer wall of the main cutting blade 12, and a secondary hook 15 is fixedly connected to the outer wall of the secondary cutting blade 13. The inner wall of the bottom of the main cutting blade 12 is fixedly connected to the handle 2, and the inner wall of the bottom of the secondary cutting blade 13 is fixedly connected to the inner wall of the handle 2.

[0012] The telescopic assembly 3 includes a folding rod 32, a telescopic rod 33 slidably connected to the inner wall of the folding rod 32, a retaining bead 34 fixedly connected to the outer wall of the telescopic rod 33, a rotating shaft 31 fixedly connected to the top outer wall of the folding rod 32, and the outer wall of the rotating shaft 31 rotatably connected to the bottom of the handle 2. The outer wall of the retaining bead 34 engages with the inner wall of the folding rod 32 through a slot 35, and the slot 35 is formed in the wall of the folding rod 32. The required length can be adjusted according to the actual working distance by the relative position of the retaining bead 34 on the telescopic rod 33 and the slot 35 on the folding rod 32. When the retaining bead 34 is embedded in the corresponding slot 35, the telescopic rod 33 automatically completes the positioning.

[0013] When in use, first remove the protective ring 11 from the secondary hook 15 of the shearing assembly 1 and snap it onto the main hook 14. This operation can release the locking state of the cutting opening. The built-in compression spring of the device releases elastic potential energy, pushing the main cutting blade 12 and the secondary cutting blade 13 to separate along the slide rail, so that the cutting opening is opened to the maximum state. At the same time, the elasticity of the spring and the sharpness of the cutting blade should be checked to ensure that the device is in normal working condition.

[0014] When performing regular distance pruning, hold handle 2 with your right hand, with four fingers encircling the outer surface of handle 2 and your thumb against the top surface of handle 2 to form a stable grip structure. This allows for effective transmission of hand force and control of the direction of the device. Align the open cutting edge with the branch to be pruned, ensuring that the branch is completely placed in the cutting area between the main and secondary cutting blades. Grip handle 2 tightly by applying force with your hand muscles to compress the built-in spring. The reaction force generated by the spring compression drives the main and secondary cutting blades to move towards each other along the guide groove, using the shearing stress of the blade edge to cut the branch. After pruning, relax your hand, and the spring will return to its original position under the action of elastic restoring force, pushing the main and secondary cutting blades apart and restoring the cutting edge to its initial open state, preparing it for the next operation.

[0015] When pruning branches high up or far away, activate the telescopic component 3 to extend the operating distance. Hold the telescopic component 3 at the bottom of the handle 2 and rotate the folding rod 32 around the pivot 31 to move it from the retracted state to the working state perpendicular to the handle 2. After the folding rod 32 is in place, the external structure automatically engages to ensure structural stability. Hold the folding rod 32 with your left hand and pull out the telescopic rod 33 with your right hand. The length can be adjusted according to the actual working distance by the relative positions of the locking bead 34 on the telescopic rod 33 and the locking groove 35 on the folding rod 32. When the locking bead 34 is inserted into the corresponding locking groove 35, the telescopic rod 33 automatically completes the positioning. Hold the extended handle 2 with both hands and use a double-arm support posture to keep the device stable. Align the cutting edge with the target branch and slowly apply force to complete the pruning. After the operation is completed, push the telescopic rod 33 to retract it into the folding rod 32, and then rotate the folding rod 32 around the pivot 31 back to the initial retracted position for easy carrying and storage of the device.
