Description
Technical Field
[0001] This utility model relates to the field of scissor technology, specifically to an anti-displacement lithium battery scissor structure. Background Technology
[0002] In garden maintenance, fruit tree pruning, and forestry management, it is frequently necessary to prune tree branches. Currently, electric shears (especially lithium-ion battery shears) are gradually replacing traditional manual shears due to their powerful performance and ease of operation. However, existing lithium-ion battery shears have a significant drawback when pruning round, smooth branches: at the moment the blade closes and applies force, the branch is prone to lateral slippage under the pressure of the blade. This not only results in an uneven cut surface but may also cause the cutting position to shift, affecting the pruning effect. Therefore, an anti-shift lithium-ion battery shear structure is proposed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides an anti-displacement lithium battery scissor structure, which solves the defects and deficiencies in existing technologies.
[0004] To achieve the above objectives, this utility model provides the following technical solution: An anti-deviation lithium-ion scissor structure includes a housing, a movable groove on one side of the housing, a lower shearing blade fixed in the movable groove, an upper shearing blade fitted to the side of the lower shearing blade, the tail end of the upper shearing blade connected to a drive unit inside the housing, a support shaft fixed on the surface of the lower shearing blade, one end of the support shaft passing through the upper shearing blade and movably connected thereto, and anti-deviation units provided at both ends of the support shaft. The anti-deviation unit includes an upper positioning plate and a lower positioning plate, and the upper positioning plate and the lower positioning plate are connected to the support shaft through a connector. Positioning protrusions are fixed on the inner sides of both the upper and lower positioning plates.
[0005] This invention relates to an anti-deviation lithium-ion battery-powered shears structure. Through the upper and lower positioning plates and the positioning protrusions on their inner sides within the anti-deviation unit, the shears can be clamped onto the branch surface before cutting. This allows the positioning protrusions to embed appropriately into the bark, providing significant anti-slip resistance and solving the problem of sliding and deflection of round branches under the blade. This ensures accurate cutting and reduces the risk of bark tearing caused by deviation.
[0006] Preferably, the anti-deviation unit includes a connecting ring movably sleeved on the surface of the support shaft, a connecting seat fixed on one side of the connecting ring, and a positioning bolt for positioning is threaded through the surface of the connecting ring.
[0007] Preferably, an upper connecting block is fixed to the inner side of the upper positioning plate, and a lower connecting block is fixed to the inner side of the lower positioning plate, and the upper connecting block and the lower connecting block are hinged to each other.
[0008] Preferably, the anti-deviation unit further includes a support rod fixed to the end of the connecting seat, the support rod being movably connected to the hinge of the upper connecting block and the lower connecting block.
[0009] Preferably, both the upper positioning plate and the lower positioning plate have an arc-shaped guide portion at their tail ends. An arc-shaped guide plate fixed to the inner side of the connecting seat is slidably disposed within the arc-shaped guide portion. Both ends of the arc-shaped guide plate are connected to springs that are connected to the side walls of the arc-shaped guide portion.
[0010] Preferably, the front ends of the upper positioning plate and the lower positioning plate extend outward to form guide insertion portions, and an insertion space is formed between the two guide insertion portions.
[0011] Preferably, the drive unit includes a battery compartment connected to one side of the housing, a motor is fixed inside the battery compartment, the output shaft of the motor is connected to a first bevel gear, and a second bevel gear that is movably connected to the side wall of the housing is meshed with one side of the first bevel gear. A drive shaft is fixed at the center of the second bevel gear, and actuating blocks are fixed on both sides of the drive shaft. The tail end of the upper shearing blade located inside the housing has a movable guide post that corresponds to the actuating block.
[0012] Preferably, a torsion return spring connected to the upper shearing blade is installed inside the support shaft.
[0013] This invention provides an anti-displacement lithium battery scissor structure. It has the following beneficial effects: This invention relates to an anti-deviation lithium-ion battery-powered shears structure. Through the upper and lower positioning plates and the positioning protrusions on their inner sides within the anti-deviation unit, the shears can be clamped onto the branch surface before cutting. This allows the positioning protrusions to embed appropriately into the bark, providing significant anti-slip resistance and solving the problem of sliding and deflection of round branches under the blade. This ensures accurate cutting and reduces the risk of bark tearing caused by deviation.
[0014] The arc-shaped guide plate structure, with springs connecting the upper and lower positioning plates at their tail ends, enables the anti-deviation unit to have an autonomous clamping function. When clamping branches of different diameters, the positioning plates can adapt to the opening and closing angle and provide continuous and flexible clamping force. This effectively achieves the effect of side-to-side anti-collision fixing of branches in the horizontal direction, while also preventing damage to the bark due to excessive rigid clamping force, thus protecting the tree.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example: like Figures 1-5As shown, this utility model embodiment provides an anti-deviation lithium battery scissor structure, including a housing 1. One side of the housing 1 has a movable groove 11, and a lower shearing blade 12 is fixed in the movable groove 11. An upper shearing blade 13 is provided on one side of the lower shearing blade 12 and is fitted therewith. The tail end of the upper shearing blade 13 is connected to a drive unit 2 inside the housing 1. Under the control of the drive unit 2, the upper shearing blade 13 can rotate relative to the lower shearing blade 12, thereby achieving closure and shearing at the blade edge. A support shaft 14 is fixed on the surface of the lower shearing blade 12. One end of the support shaft 14 passes through the upper shearing blade 13 and is movably connected to it. The upper shearing blade 13 can rotate on the surface of the support shaft 14 without sliding left or right. Anti-deviation units 3 are provided at both ends of the support shaft 14. The anti-deviation unit 3 includes an upper positioning plate 31 and a lower positioning plate 32; Positioning protrusions 34 are fixed on the inner sides of both the upper positioning plate 31 and the lower positioning plate 32.
[0019] Because the anti-deviation lithium-ion battery shears of this invention have the above-mentioned structure, the upper and lower positioning plates in the anti-deviation unit 3 and the positioning protrusions 34 on their inner sides can clamp onto the surface of the branch before cutting. This allows the positioning protrusions 34 to be appropriately embedded in the bark, providing great anti-slip resistance and solving the problem of sliding deviation of round branches under the blade. This ensures accurate cutting and reduces the risk of bark tearing caused by deviation.
[0020] Furthermore, in another embodiment, the anti-deviation unit 3 includes a connecting ring 35 movably sleeved on the surface of the support shaft 14. The connecting ring 35 can rotate freely on the surface of the support shaft 14 without falling off. A connecting seat 36 is fixed on one side of the connecting ring 35. A positioning bolt 37 for positioning is threaded through the surface of the connecting ring 35. Rotating the positioning bolt 37 can make one end of it abut against the surface of the support shaft 14, thereby forming a fixing effect on the connecting ring 35. Similarly, the angle of the anti-deviation unit 3 relative to the support shaft 14 can also be adjusted. An upper connecting block 310 is fixed to the inner side of the upper positioning plate 31, and a lower connecting block 320 is fixed to the inner side of the lower positioning plate 32. The upper connecting block 310 and the lower connecting block 320 are hinged to each other, that is, the upper connecting block 310 and the lower connecting block 320 are movably connected, so that the upper positioning plate 31 and the lower positioning plate 32 can rotate relative to each other along the hinge point of the upper connecting block 310 and the lower connecting block 320. The anti-deviation unit 3 also includes a support rod 38 fixed to the end of the connecting seat 36, and the support rod 38 is movably connected to the hinge of the upper connecting block 310 and the lower connecting block 320.
[0021] Because the anti-deviation lithium battery scissor structure of this utility model has the above structure, the connection ring 35 and the connection seat 36 can form a supporting effect on the upper positioning plate 31 and the lower positioning plate 32, so that they can maintain the positional relationship with the lower shearing blade 12 in the natural state, which is beneficial to its positioning function before shearing.
[0022] Furthermore, in another embodiment, the tail ends of the upper positioning plate 31 and the lower positioning plate 32 are both formed with arc-shaped guide portions 39. Arc-shaped guide plates 390 fixed to the inner side of the connecting seat 36 are slidably arranged in the two arc-shaped guide portions 39. Both ends of the arc-shaped guide plates 390 are connected to springs 391 connected to the side walls of the arc-shaped guide portions 39. Through the action of the springs 391, the ends of the upper positioning plate 31 and the lower positioning plate 32 can be in a state of close proximity to each other in their natural state. The front ends of the upper positioning plate 31 and the lower positioning plate 32 extend outward to form guide insertion portions 392, and an insertion space 393 is formed between the two guide insertion portions 392.
[0023] Because the anti-deviation lithium battery scissor structure of this utility model has the above-mentioned structure, such as Figure 1 As shown, the anti-deviation unit 3 is in a closed state at this time. When cutting is required, the guide insertion part 392 is pressed against one side of the branch, and then the guide insertion part 392 is opened by the action of the branch, so that the branch is placed into the insertion space 393. During this process, the positioning convex blade 34 can be appropriately embedded in the bark. Figure 3 (This is a schematic diagram of the state embedded in the branch), providing strong resistance to lateral slippage, which reduces shear deviation and improves the accuracy of shearing during subsequent shearing operations.
[0024] Furthermore, in another embodiment, the drive unit 2 includes a battery compartment 21 connected to one side of the housing 1, a motor 22 fixed inside the battery compartment 21, and a battery inside the battery compartment 21 for supplying power to the motor 22. The output shaft of the motor 22 is connected to a first bevel gear 23, and one side of the first bevel gear 23 is engaged with a second bevel gear 24 that is movably connected to the side wall of the housing 1. A drive shaft 25 is fixed at the center of the second bevel gear 24, and a toggle block 26 is fixed on both sides of the drive shaft 25. The tail end of the upper shearing blade 13 located in the housing 1 has a movable guide post 130 that is correspondingly arranged with the toggle block 26. The support shaft 14 is equipped with a torsion return spring connected to the upper shearing blade 13. In this embodiment, the torsion return spring provides a supporting and restoring force to the upper shearing blade 13, so that after it is driven to close in the direction of the lower shearing blade 12, the upper shearing blade 13 can be reset by the action of the torsion return spring. Since the shearing drive principle and reset action of the scissors are well known to those skilled in the art, no further elaboration is required in this embodiment.
[0025] Because the anti-deviation lithium battery scissor structure of this utility model has the above-mentioned structure, such as Figure 5 As shown, the start motor 22 drives the first bevel gear 23 to rotate at its output end. The first bevel gear 23 can drive the second bevel gear 24 on one side to rotate, causing the second bevel gear 24 to drive the toggle block 26 on one side to rotate clockwise. The toggle block 26, which rotates 180 degrees clockwise, can abut against the movable guide post 130 on one side, causing the upper shearing blade 13 to close in the direction of the lower shearing blade 12, thus forming a shearing action.
