Description

Technical Field

[0001] This invention relates to the field of fruit tree pruning, and in particular to a pruning device for navel orange trees. Background Technology

[0002] Existing fruit tree pruning tools are limited in length, making them suitable only for shorter fruit trees. When encountering taller fruit trees, existing pruning tools are difficult to use.

[0003] To address this, a fruit tree pruning device, such as the one with patent number CN220369102U, was developed. While this device can extend the overall length of the handheld part by rotating the extension rod inside the handheld handle, thus facilitating the pruning of higher branches and leaves, it has the following drawbacks in actual operation: When the extension rod is rotated to slide out of the handheld handle, its outer threaded structure is exposed, making it very easy for it to get dirty, which affects subsequent threaded connection work. At the same time, it cannot effectively guarantee that the extension rod will not rotate within the threaded hole in the handheld handle during subsequent operation. This could cause the extension rod to rotate within the threaded hole in the handheld handle during operation, changing the overall length of the handheld part, thus affecting the user experience and potentially impacting the subsequent pruning effect and efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a pruning device for navel orange trees.

[0005] The technical problem of this invention is mainly solved by the following technical solution: A pruning device for navel orange trees includes two sets of cylindrical handles arranged in a cross configuration, wherein the intersection of the two sets of handles is movably connected by a pivot, and one end of each handle is provided with a shear head. The scissor head is covered with a rigid protective sleeve, and the handle part opposite to the scissor head is covered with a spiral tube integrally formed therewith. The outer wall of the spiral tube is provided with a bearing with a strip groove. It also includes a flat gripper corresponding to the handheld handle. One end of the gripper is provided with a threaded channel that fits onto the corresponding screw tube and the handheld handle. The threaded channel is threaded and fixed to the screw tube. A cover plate is provided at the open end of the threaded channel to seal it. The cover plate is provided with a through hole for the handheld handle to pass through. The gripper is also provided with a positioning mechanism corresponding to the slot. The positioning mechanism includes a groove provided on the side wall of the threaded channel. A locking block that can be embedded in the corresponding slot is provided in the groove. A screw is fixed on the locking block by a bearing. The screw passes through a threaded hole on the side wall of the threaded channel.

[0006] Preferably, one end of the handheld handle is provided with a hook corresponding to the strip groove, and the hook is provided with a hanging ring connected to the protective sleeve by a connecting rope.

[0007] Preferably, the handle is provided with a protrusion on the same side as the scissor head, wherein the upper and lower sets of protrusions are attached to each other.

Detailed Implementation

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] A pruning device for navel orange trees includes two sets of cylindrical hand handles 1 arranged in a cross configuration, wherein the intersection of the two sets of hand handles 1 is movably connected by a pivot, and one end of each hand handle 1 is provided with a shear head 2. The scissor head 2 is covered with a rigid protective sleeve 3, and the handle 1, which is opposite to the scissor head 2, is covered with a screw tube 4 integrally formed therewith. The outer wall of the screw tube 4 is provided with a strip groove 5. It also includes a flat gripper 6 corresponding to the hand-held lever 1. One end of the gripper 6 is provided with a threaded channel 7 that is sleeved on the corresponding screw tube 4 and the hand-held lever 1. The threaded channel 7 is threaded and fixed to the screw tube 4. A cover plate 8 is provided at the open end of the threaded channel 7 to seal it. The cover plate 8 is provided with a through hole for the hand-held lever 1 to pass through. The cover plate 8 is locked and fixed to the end of the gripper 6 by bolts. The gripper 6 is also provided with a positioning mechanism 9 corresponding to the strip groove 5. The positioning mechanism 9 includes a groove 91 provided on the side wall of the screw channel 7. A locking block 92 that can be embedded in the corresponding strip groove 5 is provided in the groove 91. A screw 94 is fixed on the locking block 92 by a bearing 993. The screw 94 passes through a screw hole 95 on the side wall of the screw channel 7.

[0017] In this embodiment, one end of the handheld lever 1 is provided with a hook 10 corresponding to the strip groove 5. The hook 10 is provided with a hanging ring connected to the protective sleeve 3 via a connecting rope. In this embodiment, the protective sleeve 3 is hung on the hook 10 by the hanging ring, thereby effectively preventing it from separating from the trimming mechanism. At this time, the protective sleeve 3 plays a role in wrapping and protecting the scissor head 2, preventing it from accidentally injuring other objects or workers. Furthermore, by aligning the screw 94 with the corresponding hook 10, it is possible to indirectly know whether the locking block 92 in the positioning mechanism 9 is aligned with the corresponding strip groove 5, so that the locking block 92 in the positioning mechanism 9 can be smoothly embedded into the strip groove 5 in subsequent operations. When the locking block 92 is embedded in the strip groove 5, the handheld lever 1 can abut against the positioning mechanism 9 through the side wall of the strip groove 5, thereby effectively preventing the screw channel 7 on the gripper 6 from rotating on the screw tube 4 without human intervention, thus indirectly fixing the length of the handheld part of the trimming mechanism.

[0018] like Figure 1 , 2 As shown, the hand handle 1 is provided with a protrusion 11 on the same side as the scissor head 2, wherein the upper and lower sets of protrusions 11 are attached to each other.

[0019] In this embodiment, the width of the locking block 92 is adapted to the size of the groove 91, and the edges of the locking block 92 are all rounded. By locking the side wall of the locking block 92 in the groove 91, when the screw 94 in the screw hole 95 is rotated to move it, its end can rotate in the bearing 93 and push the locking block 92 out of the groove 91 and into the corresponding strip groove 5. The rounded edges of the locking block 92 are designed to facilitate guiding the locking block 92 into the strip groove 5.

[0020] The end of the hand-held lever portion 1 within the screw-in channel 7 is provided with a columnar sliding channel 12, and a positioning rod 13 that is inserted into and adapted to the sliding channel 12 is provided on the sealed end of the screw-in channel 7.

[0021] In this embodiment, the end of the screw 94 extends to the outside of the gripper 6 and is fixed with a mounting block 14. People can rotate the screw 94 by pinching the mounting block 14.

[0022] In this embodiment, the protective sleeve 3 can protect the head of the trimming device and prevent the trimming device from opening. When in use, the protective sleeve 3 can be removed from the head of the trimming device.

[0023] When it is necessary to adjust the overall length of the hand-held part of the pruning device for pruning taller fruit trees, the hand gripper 6 is rotated to drive the screw channel 7 to rotate on the screw tube 4. The hand gripper 6 also drives the through hole on the cover plate 8 to rotate on the hand gripper 1, while the screw channel 7 drives the positioning rod 13 to rotate in the sliding channel 12. This adjusts the overall length of the hand-held part formed by the hand gripper 1 and the hand gripper 6. During the above process, the screw tube 4 is sealed in the sealed cavity formed by the screw channel 7 and the cover plate 8 to prevent foreign objects from contacting the threads of the above components, thus ensuring the normal use of the threads in the above components. In the subsequent process, the hand gripper 6 can be separated from the cover plate 8 by unscrewing the bolts, and then the hand gripper 6 can be removed for replacement or maintenance.

[0024] After the position of the gripper 6 is adjusted, it is finely adjusted so that the positioning mechanism 9 on its side wall is aligned with the corresponding hook 10. At this time, it can be indirectly known whether the locking block 92 in the positioning mechanism 9 is aligned with the corresponding strip groove 5. Then, the screw 94 is rotated so that it moves spirally in the screw hole 95 and the bearing 93, thereby pushing one end of the locking block 92 to slide out of the slot 91 and slowly slide into the strip groove 5. The other end of the locking block 92 does not slide out of the slot 91 completely, so that it can slide out of the strip groove 5 smoothly and retract into the slot 91. When the locking block 92 is embedded in the strip groove 5, the hand gripper 1 can abut against the positioning mechanism 9 through the side wall of the strip groove 5, thereby effectively preventing the screw channel 7 on the gripper 6 from rotating on the screw tube 4 without human intervention, thus indirectly fixing the length of the hand gripper part of the trimming mechanism.

[0025] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
