Description

Technical Field

[0001] This utility model relates to the field of electric shears technology, specifically a multi-functional electric shears for gardening. Background Technology

[0002] Electric garden shears are widely used power-operated pruning tools in modern gardening. Driven by electricity, they feature double-edged blades that reciprocate at high speed, efficiently trimming hedges and shrubs, and finely shaping lawn edges and various planar features. Compared to traditional manual trimming, they significantly improve work efficiency and finish while drastically reducing labor intensity, making them an indispensable maintenance tool in courtyards, parks, and municipal greening projects.

[0003] However, this tool still poses certain safety risks during use: when pruning shorter branches, the cut short branches are prone to flying off instantly under the shearing force of the blade. If the operator or people around them are not effectively protected, they are easily injured by the flying short branches, which poses a safety hazard. Therefore, we propose a new type of multi-functional electric shears for gardening. Utility Model Content

[0019] This utility model provides a technical solution: Please see Figures 1-4 A multi-functional electric shears for gardening includes an electric shears body 1, a fixed blade 2 fixedly mounted on the electric shears body 1, a short branch clamping structure 3 provided on the fixed blade 2, and a hollow base block 31 fixedly mounted on the fixed blade 2. First telescopic springs 32 are fixedly mounted at both ends of the top of the hollow base block 31, an airbag arc block 33 is fixedly mounted at the upper end of the first telescopic springs 32, and a telescopic hose 34 is fixedly mounted at the center of the bottom of the airbag arc block 33. A rigid conduit 35 communicating with the inner cavity of the hollow base block 31 is fixedly installed on the side end of the block 31. An air cylinder 36 is fixedly installed at the end of the rigid conduit 35 away from the hollow base block 31. A piston cover 37 is slidably sealed to the cavity of the air cylinder 36. A pressure rod 38 penetrating the air cylinder 36 is fixedly installed at the bottom of the piston cover 37. A second telescopic spring 39 is fixedly installed between the piston cover 37 and the air cylinder 36. The pressure rod 38 penetrates the second telescopic spring 39. A hollow pressure block 310 is fixedly installed at the lower end of the pressure rod 38.

[0020] The short branch is placed on the airbag arc block 33. When the moving blade 5 cuts, it squeezes the airbag arc block 33, which compresses the first telescopic spring 32. The internal gas enters the air cylinder 36 through the telescopic hose 34, the hollow base block 31, and the rigid conduit 35, pushing the piston cover 37 down and compressing the second telescopic spring 39. This causes the pressure rod 38 and the hollow pressure block 310 to move closer to the airbag arc block 33. The two work together to clamp the short branch. After the cutting is completed, all components return to their original positions under the action of the spring. Function: Through the linkage of the electric shears body 1, the fixed blade 2, and the hollow base block 31, the first telescopic spring 32, and the airbag arc block 33 of the short branch clamping structure 3, the short branch during the cutting is firmly clamped, preventing it from flying due to the cutting force and eliminating safety hazards.

[0021] In some embodiments, the telescopic hose 34 is fixedly installed between the hollow base block 31 and the airbag arc block 33, and the telescopic hose 34 is interconnected with both the hollow base block 31 and the airbag arc block 33.

[0022] In this embodiment, when the moving blade 5 squeezes the airbag arc block 33, the gas inside the airbag arc block 33 flows into the hollow base block 31 through the telescopic hose 34 that is fixedly installed between it and the hollow base block 31 and is interconnected, providing a stable channel for gas transmission.

[0023] In some embodiments, the rigid conduit 35 is fixedly connected to the fixed blade 2 by a pipe clamp and a transverse connecting rod, wherein the pipe clamp and the transverse connecting rod are fixedly connected.

[0024] In this embodiment, the rigid conduit 35 is firmly fixed to the fixed blade 2 by the pipe clamp and the transverse connecting rod, and does not shift during gas flow and component linkage. Its function is to firmly fix the rigid conduit 35, ensure its stable connection with the hollow base block 31, and provide a reliable channel for gas transmission for the short branch clamping structure 3.

[0025] In some embodiments, rubber pads adapted to the airbag arc block 33 are fixedly installed on the top surface and the bottom surface of the hollow pressure block 310.

[0026] In this embodiment, when the pressure rod 38 drives the hollow pressure block 310 to approach the airbag arc block 33 to clamp the short branch, the rubber pads fixed on the surfaces of the two will adhere to the short branch with the clamping action, maintaining contact throughout the process of the short branch being fixed and cut. Its function is to enhance the friction between the airbag arc block 33 and the hollow pressure block 310 on the short branch, prevent the short branch from sliding during clamping or cutting, and at the same time buffer the clamping force to protect the short branch from being pinched, ensuring the stable clamping effect of the short branch clamping structure 3.

[0027] In some embodiments, the extendable length of the pressure rod 38 is much greater than the distance between the airbag arc block 33 and the hollow pressure block 310.

[0028] In this embodiment, when the gas in the air cylinder 36 pushes the piston cover 37 to move the pressure rod 38 downward, since the extendable length of the pressure rod 38 is much greater than the distance between the airbag arc block 33 and the hollow pressure block 310, it can ensure that the hollow pressure block 310 has sufficient downward stroke, smoothly approach and fit the airbag arc block 33 to complete the clamping of the short branch, and can also move away fully with the component after shearing; its function is to ensure that the clamping stroke of the short branch clamping structure 3 is sufficient, adapt to short branches of different thicknesses, and avoid the clamping being unstable due to the limited extension and retraction of the pressure rod 38.

[0029] Please see Figure 4The hollow pressure block 310 is made of a transparent plastic shell, and several lighting tubes 4 are fixedly installed in the inner cavity of the hollow pressure block 310.

[0030] When pruning in dim lighting conditions, several lighting tubes 4 inside the hollow pressure block 310 can be turned on, allowing light to pass through the hollow pressure block 310 made of transparent plastic shell and shine directly onto the airbag arc block 33 area on the fixed blade 2, providing the operator with a clear view for positioning and placing short branches. Its function is to solve the visibility problem in dim lighting conditions, help to accurately place short branches in the clamping area, ensure the stable clamping effect of the short branch clamping structure 3, improve pruning accuracy, avoid operational errors caused by poor visibility, and further eliminate the safety hazard of short branches flying.

[0031] Please see Figure 1 and Figure 3 A movable blade 5 is rotatably connected to the fixed blade 2 via a rotating shaft. A servo motor 6 is fixedly installed inside the electric scissor body 1. A small bevel gear 7 is fixedly installed at the output end of the servo motor 6. A large bevel gear 8, which is rotatably connected to the electric scissor body 1, meshes with the outer side of the small bevel gear 7. A toggle block 9 is fixedly installed on the shaft of the large bevel gear 8.

[0032] After the electric shears body 1 is started, the servo motor 6 inside it runs and drives the small bevel gear 7 at the output end to rotate. The small bevel gear 7 meshes with the large bevel gear 8 on the electric shears body 1 to make them work together. The actuating block 9 on the shaft of the large bevel gear 8 rotates accordingly and pushes the moving blade 5, causing the moving blade 5 to rotate around the axis of the fixed blade 2, forming a shearing engagement with the fixed blade 2. Its function is to provide stable power for pruning and realize the precise reciprocating shearing of the moving blade 5. At the same time, the downward pressing action of the moving blade 5 will trigger the short branch clamping structure 3 to start, ensuring the linkage between shearing and clamping.

[0033] Please see Figure 1 and Figure 3 A force-bearing block 10 is fixedly installed at one end of the moving blade 5, and a return spring 11 is fixedly installed on the force-bearing block 10. The end of the return spring 11 away from the force-bearing block 10 is fixedly connected to the electric scissor body 1.

[0034] When the actuating block 9 on the large bevel gear 8 rotates and abuts against the force block 10 at one end of the moving blade 5, the force block 10 drives the moving blade 5 to rotate and shear, while simultaneously compressing the return spring 11 fixed thereto, causing it to undergo elastic deformation. After the actuating block 9 rotates past the force block 10, the return spring 11 drives the moving blade 5 to quickly return to its initial position. Its function is to realize the reciprocating shearing action of the moving blade 5, ensuring the continuity and efficiency of the pruning operation. At the same time, after the moving blade 5 returns to its original position, the clamping components such as the airbag arc block 33 also return to their original position, releasing the short branches so that they fall off smoothly, further ensuring operational safety.

[0035] In practical use, the working principle of this utility model is as follows: After the multi-functional electric garden shears are started, the servo motor 6 fixedly installed inside the electric shears body 1 immediately starts to run, driving the small bevel gear 7 fixed at the output end to rotate synchronously. Since the small bevel gear 7 meshes with the large bevel gear 8 rotatably connected to the electric shears body 1, the large bevel gear 8 is linked and drives the actuating block 9 on its shaft to rotate together. During the rotation of the actuating block 9, it will contact the force block 10 fixed at one end of the moving blade 5 and apply a pushing force, causing the moving blade 5 to rotate around the rotating shaft on the fixed blade 2, forming a precise cutting engagement with the fixed blade 2. The return spring 11 connected to the force block 10 undergoes elastic deformation under the action of the pushing force. When the actuating block 9 rotates past the force block 10, the restoring force of the return spring 11 will quickly drive the moving blade 5 to return to its original position, preparing for the next cutting action. This cycle achieves efficient and continuous pruning operations.

[0036] To address the safety hazard of flying debris when pruning short branches with existing electric shears, this device provides targeted protection through a short branch clamping structure 3. Before pruning, the operator must accurately place the short branch on the airbag arc block 33 on the fixed blade 2. The top of the airbag arc block 33 is higher than the blade of the fixed blade 2, which can provide support and positioning for the short branch in advance, avoiding placement deviation that could lead to clamping failure. When the moving blade 5 moves downwards and comes into contact with the short branch during the shearing cycle, the continuous downward pressure of the moving blade 5 will simultaneously squeeze the airbag arc block 33, causing it to move downwards and compress the first telescopic springs 32 on both sides. After the airbag arc block 33 is deformed by pressure, the gas inside it flows into the hollow base block 31 through the interconnected telescopic hose 34, and then through the hollow base block 31 into the rigid conduit 35 connected to it. Finally, the gas is delivered to the inside of the air cylinder 36, increasing the pressure inside the cavity, which in turn pushes the piston cover 37 to move downwards against the elastic force of the second telescopic spring 39. The piston cover 37 simultaneously drives the pressure rod 38 that passes through the air cylinder 36 to move downwards, so that the hollow pressure block 310 at the lower end of the pressure rod 38 simultaneously approaches the airbag arc block 33. The rubber pads fixed on the opposite surfaces of the two enhance the friction, achieving a stable clamping of the short branch. At this time, the moving blade 5 continues to complete the shearing action. The clamped and fixed short branch will not splash due to the shearing force during the cutting process, effectively eliminating safety hazards.

[0037] After a shearing operation is completed, the moving blade 5 returns to its original position under the action of the return spring 11, the pressure on the airbag arc block 33 disappears, the restoring force of the first telescopic spring 32 pushes the airbag arc block 33 to return to its original position, its internal volume recovers and the air pressure in the air cylinder 36 decreases, the second telescopic spring 39 drives the piston cover 37, the pressure rod 38 and the hollow pressure block 310 to return to their original positions, releasing the clamping on the short branch, so that the cut short branch falls off smoothly without affecting subsequent pruning operations.

[0038] In addition, the hollow pressure block 310 is made of a transparent plastic shell, and the several lighting tubes 4 fixed in its inner cavity can provide sufficient lighting in the dimly lit working environment, helping the operator to accurately locate the short branch and ensure that the short branch can be accurately placed in the clamping area of ​​the airbag arc block 33. This not only improves the accuracy of pruning, but also further ensures the protective effect of the clamping structure, allowing garden pruning operations to be carried out smoothly under the premise of safety and efficiency.

[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
