Description

A foldable garden maintenance pruning device Technical Field

[0001] This invention relates to the field of gardening tools, specifically to a foldable garden maintenance pruning device. Background Technology

[0002] Currently, the pruning of tall branches in landscaping and urban greening generally uses hand saws and pruning shears, which require manual climbing. The treatment of branches near high-voltage lines poses a great safety hazard to workers. In addition, there are mechanically powered hydraulic shears, which require multiple people to operate, resulting in low work efficiency and making it difficult to meet the requirements of landscaping and urban greening. Furthermore, existing pruning devices have limited functions, low cutting efficiency, and are inconvenient to carry.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a manual high-efficiency folding hydraulic pruning shear [CN 201220694049.8], which includes a shear head, a folding rod, and a manual lever-type hydraulic pump. The shear head is located at the head, and the manual lever-type hydraulic pump is located at the tail, connected by the folding rod. It also includes: a pump body, a fixed handle, a movable handle, a connecting rod, a plunger 1, a plunger 2, an unloading valve, a return spring, an oil plug, an unloading valve operating component, an unloading handle, an unloading handle mounting base, a fixed handle insulating sleeve, a movable handle insulating sleeve, a first check valve, a second check valve, an oil suction pipe, a rubber oil bladder, a vent, a cylinder, a piston, a piston rod, a piston return spring, a cylinder head, a support rod, shears, an upper arm, a lower arm, a connecting lock, a high-pressure oil pipe, and a return oil pipe. When the folding lock is opened, the upper arm of the folding rod is rotated to the right along the hinge axis, so that the shear head is pressed against one side of the pump body, completing the folding.

[0004] The above solution has solved the problem of low working efficiency of pruning devices in the prior art to a certain extent, but the solution still has many shortcomings, such as: limited function, low pruning efficiency and inconvenience to carry. Summary of the Invention

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] As shown in Figures 1-5, a foldable garden maintenance pruning device includes a foldable connecting rod 1, a pruning body 2 at one end of the foldable connecting rod 1, a sliding drive mechanism 3 for driving the opening and closing of the pruning body 2 is slidably mounted on the foldable connecting rod 1, an extension saw body 4 is inserted inside the pruning body 2, and a linkage component 5 is provided at one end of the extension saw body 4 that is connected to and linked with the sliding drive mechanism 3, and a folding positioning mechanism 6 is provided in the middle of the foldable connecting rod 1.

[0025] The pruning body 2 includes a vertical pruning section 21 arranged symmetrically. The lower end of the vertical pruning section 21 is provided with a symmetrically arranged pressing arc section 22. The end of the pressing arc section 22 away from the vertical pruning section 21 is provided with a cross-arranged linkage handle section 23. The linkage handle section 23 is rotated and positioned by a rotating connecting shaft 24 provided at one end of the folding connecting rod 1.

[0026] The vertical shearing part 21 is used to cut branches, and the arc-shaped pressing part is used to press the outer wall of thick-diameter branches, thus achieving multiple uses.

[0027] As can be seen, the sliding drive mechanism 3 includes an arc-shaped sliding half-sleeve 31, with pruning drive rods 32 on both sides of the sliding half-sleeve 31. The end of the pruning drive rod 32 away from the sliding half-sleeve 31 is rotatably connected and positioned to the linkage handle part 23 via a rotating shaft 33. Sliding blocks 34 are symmetrically arranged on both sides of the inner wall of the sliding half-sleeve 31, and guide grooves 35 are provided on both sides of the folding connecting rod 1 for the sliding blocks 34 to be inserted. There is an anti-contact gap 36 between the inner wall of the sliding half-sleeve 31 and the folding connecting rod 1.

[0028] When the sliding half-body 31 slides up and down, the pruning drive rod 32 drives the linkage handle 23 to move synchronously and crosswise, thereby realizing the pruning action of the vertical pruning part 21.

[0029] Obviously, a sliding drive rod 311 is connected to the sliding half-body 31. The sliding drive rod 311 is connected to a sliding connecting block 312 located at the end of the folding connecting rod 1 away from the pruning body 2. The folding connecting rod 1 is provided with a pull groove 313 into which the sliding connecting block 312 can be inserted. The sliding connecting block 312 is provided with a drive handle 314, and the drive handle 314 is provided with a positioning buckle 315. The folding connecting rod 1 is provided with a locking positioning hole 316 into which the positioning buckle 315 can be inserted.

[0030] When the drive handle 314 is pulled, the sliding drive rod 311 drives the sliding half-sleeve 31 to slide synchronously. When not in use, the drive handle 314 is inserted into the locking positioning hole 316 by the positioning buckle to realize the closure of the vertical shearing part 21.

[0031] Furthermore, the pull groove 313 here is equipped with a spring for keeping the sliding connecting block 312 moving toward the upper end of the pull groove 313, which is designed to enable the vertical shearing part 21 to open quickly after shearing.

[0032] Furthermore, the linkage component 5 includes a connecting shaft 51 disposed at the end of the extended saw body 4. The connecting shaft 51 is connected to the rotating shaft 33 on the corresponding side through the first connecting frame 54. The folding connecting rod 1 is provided with a strip-shaped sliding groove 52. A sliding seat 53 is provided in the strip-shaped sliding groove 52, and the sliding seat 53 is connected to the connecting shaft 51 through the second connecting frame 55.

[0033] When the pruning drive rod 32 drives the linkage handle 23 to move synchronously and crosswise, the first connecting frame 54 and the second connecting frame 55 deform in a V-shape, thereby driving the extension saw body 4 to extend and retract, thus realizing sawing.

[0034] Furthermore, the sliding seat 53 is provided with a positioning shaft 56, and a positioning link 57 is connected to the positioning shaft 56. The end of the positioning link 57 away from the positioning shaft 56 is provided with a positioning latch 58. The folding connecting rod 1 is provided with a plurality of latch holes 59 corresponding to the positioning latch 58, and the positioning link 57 is provided with an elastic part 571.

[0035] When positioning the extension saw body 4, it is pulled to the set position by the positioning link 57, and the positioning is achieved by the mutual locking of the locking hole 59 and the positioning lock 58. When positioning the extension saw body 4, the vertical cutting part 21 moves passively and closes.

[0036] Specifically, the folding connecting rod 1 has a connecting upper part 11 and a gripping lower part 12. The connecting upper part 11 and the gripping lower part 12 are connected by a hinge shaft 13. The hinge shaft 13 is provided with an arc-shaped folding clearance groove 14. The gripping lower part 12 is provided with a stacking slot 15 on one side, which allows the connecting upper part 11 to be partially inserted after folding.

[0037] More specifically, the upper part 11 and the lower part 12 are connected by an elastic band 16 at the folding relief groove 14, and the upper part and the lower part 12 are connected by a pull-out structure 17 at the hinge axis 13.

[0038] In detail, the folding positioning mechanism 6 includes a positioning sleeve 61 disposed on the outer wall of the connecting upper part 11, a plug seat 62 slidably disposed on the gripping lower part 12, a positioning plug rod 63 disposed at one end of the plug seat 62 facing the positioning sleeve 61 for inserting into the positioning sleeve 61 to connect and position the connecting upper part 11 and the gripping lower part 12, and sliding connecting grooves 64 disposed on both sides of the gripping lower part 12 for the plug seat 62 to slide into the inner wall of the circumference.

[0039] The folding positioning mechanism 6 causes the upper part 11 and the lower part 12 to bend, reducing space occupation, and can form a vertical positioning when opened.

[0040] Preferably, the vertical cutting section 21 is provided with a pruning blade 25, and the extended saw body 4 is provided with a corresponding arc-shaped extrusion section 41 located on the pressing arc section 22, and the length of the arc-shaped extrusion section 41 is greater than the length of the pressing arc section 22.

[0041] In summary, the principle of this embodiment is as follows: When in use, the upper part 11 is opened and the lower part 12 is held. Vertical positioning is achieved through the mutual insertion of the positioning sleeve 61 and the positioning rod 63. During cutting, the sliding half-sleeve 31 is driven to move downward by the drive handle 314, and the pruning drive rod 32 drives the linkage handle 23 to move synchronously and crosswise, thereby realizing the cutting action of the vertical cutting part 21. Secondly, when the pruning drive rod 32 drives the linkage handle 23 to move, due to the setting of the linkage component 5, the first connecting frame 54 and the second connecting frame 55 move in a V-shape, thereby driving the extension saw body 4 to extend and retract, realizing sawing. When not in use, the positioning latch 58 on the positioning link 57 is locked in the latch hole 59 to fix the extension saw body 4. The positioning latch on the drive handle 314 is inserted into the locking positioning hole 316 to close the vertical cutting part 21.
