[0002] Pruning shears are a common gardening tool used in landscaping maintenance. They can be used to trim the branches of flowers, fruit trees, and forest trees, allowing them to grow according to the grower's wishes. To save effort and improve efficiency, electric pruning shears have been developed. These shears have greater torque and can easily cut thicker branches, and are also convenient for trimming lawns and shrubs. A search revealed that patent application number 202122711946.7 discloses a high-stability lithium-ion battery pruning shear. The key technical features are: a housing and a battery box; the housing contains a shear assembly, a drive motor, and a control chip; the battery box is fixedly mounted on the bottom of the housing; a slide rail is slidably connected to both sides of the battery compartment; screws are fixedly mounted on the bottom plate of the battery compartment; nail holes are provided in the battery box at corresponding nail slot positions; a conductive plate is fixedly mounted on the bottom of the battery compartment; a conductive post is fixedly mounted on the bottom of the conductive plate; and an external component is detachably mounted on the outside of the battery box.

[0003] However, in actual use, the applicant found that when extending the device, it is achieved by the upper tube sliding along the lower tube. The upper and lower tubes are limited by a locking block in the slot in the fixing component. Since there is a gap between the locking block and the slot, and the gap will become larger with wear, the connection between the upper and lower tubes is not stable enough. In view of this, we propose a high-stability lithium battery pruning shear. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A high-stability lithium-ion battery pruning shear includes a handle 1 and a pruning shear body 3. A central rod 11 is fixedly installed through the middle of the handle 1, and an extension rod 2 is slidably connected inside the central rod 11. The pruning shear body 3 is fixedly installed at the front end of the extension rod 2. Reinforcing rods 4 are symmetrically slidably connected to the outer walls of the handle 1 on both sides of the extension rod 2. Connecting grooves 12 are symmetrically opened at the top and bottom of the handle 1, and the two reinforcing rods 4 slide along the two connecting grooves 12 respectively. The front ends of the two reinforcing rods 4 are fixedly connected to the pruning shear body 3. The central rod 11 is rotatably connected by bearings. A screw 6 is provided, with its front end threaded into the extension rod 2. The rear end of the screw 6 extends to the outside of the central rod 11 and is fitted with an adjusting handle 61. A push-button switch 7 is fixedly installed on one side of the rear end of the handheld rod 1. The push-button switch 7 is electrically connected to the lithium-ion pruning shears body 3 via a wire. Arc-shaped anti-slip sleeves 5 are symmetrically fixed on both sides of the handheld rod 1. One side of the arc-shaped anti-slip sleeve 5 has a clearance groove 51 for avoiding the lithium-ion pruning shears body 3. By rotating the screw 6 clockwise, the extension rod 2 moves forward and extends smoothly from the central rod 11, which can move the lithium-ion pruning shears body 3 forward, allowing the lithium-ion pruning shears body 3 to move forward. The electric pruning shears body 3 is suitable for pruning branches at higher elevations. This adjustable extension method offers greater stability, and the reinforcing rod 4 further enhances the stability of the extension structure. The arc-shaped anti-slip sleeve 5 increases the friction between the handle 1 and the pruner's hand, making the grip on the handle 1 more stable and reliable. This better prevents the handle 1 from slipping out of the hand and causing damage to the lithium-ion pruning shears body 3. During use, the user holds the handle 1 and controls the moving blades on the lithium-ion pruning shears body 3 by pressing the button switch 7 with their thumb. The blade moves towards the fixed blade and prunes the branches through the cooperation of the moving blade and the fixed blade. When it is necessary to prune branches at a higher position, the screw 6 can be rotated by manually turning the adjusting handle 61 clockwise. The rotation of the screw 6 can drive the extension rod 2 to move forward along the inner side wall of the central rod 11 and extend out from the inside of the central rod 11. The movement of the extension rod 2 can drive the lithium battery pruning shear body 3 to move forward, and can drive the two reinforcing rods 4 to move forward along the connecting groove 12 through the lithium battery pruning shear body 3, so as to extend the length of the device and thus be able to prune branches at a higher position.

[0022] The outer wall of the handheld lever 1 has a T-shaped groove 13, and the inner wall of the arc-shaped anti-slip sleeve 5 has a T-shaped slider 53, which slides in conjunction with the T-shaped groove 13. The two ends of the handheld lever 1 are symmetrically and elastically connected to limit posts 8 via springs 9. The arc-shaped anti-slip sleeve 5 is fixed to the handheld lever 1 by the limit posts 8. The two ends of the handheld lever 1 have symmetrical limit grooves 14, and the tail end of the limit posts 8 has a limit slider that slides along the limit groove 14. The springs 9... The spring 9 is installed in the limiting slide groove 14. One end of the spring 9 abuts against the inner wall of the limiting slide groove 14, and the other end of the spring 9 abuts against the limiting slider at the tail end of the limiting column head 8. The rear end of the arc-shaped anti-slip sleeve 5 has a limiting hole 52. The head of the limiting column head 8 is stuck in the limiting hole 52. By pressing the limiting column head 8 inward, the head of the limiting column head 8 is moved out of the limiting hole 52, and the arc-shaped anti-slip sleeve 5 can be removed from the handle 1 for replacement of aged or damaged arc-shaped anti-slip sleeves 5. The operation is convenient. When the arc-shaped anti-slip sleeve 5 ages or is damaged and needs to be replaced, the limiting pin 8 can be manually pressed inward to move the head of the limiting pin 8 out of the limiting hole 52. Then, the arc-shaped anti-slip sleeve 5 can be pulled backward to drive the T-shaped slider 53 out of the T-shaped groove 13, thus removing the arc-shaped anti-slip sleeve 5 from the handle 1. Next, align the T-shaped slider 53 on the new arc-shaped anti-slip sleeve 5 and slide it into the T-shaped groove 13. Then, manually press the limiting pin 8 inward to press the head of the limiting pin 8 into the limiting groove 14. At this time, the limiting pin 8 moves into the limiting groove 14 to compress the spring 9. Then, the front end of the arc-shaped anti-slip sleeve 5 is pulled, which drives the T-shaped slider 53 to slide forward along the T-shaped groove 13 until the T-shaped slider 53 slides to the front end of the T-shaped groove 13. At this time, the limiting hole 52 moves to the limiting pin 8. Under the elastic force of the spring 9, the limiting pin 8 can pop out and automatically lock into the limiting hole 52, limiting the arc-shaped anti-slip sleeve 5. This completes the quick replacement of the arc-shaped anti-slip sleeve 5.

[0023] Working principle: During use, the operator holds the handle 1 and presses the button switch 7 with their thumb to control the movement of the moving blade on the lithium-ion pruning shears body 3 towards the fixed blade. The movement of the moving blade and the fixed blade work together to prune branches. When pruning branches at higher positions is needed, the adjusting handle 61 can be manually turned clockwise to rotate the screw 6. The rotation of the screw 6 causes the extension rod 2 to move forward along the inner wall of the central rod 11, extending from inside the central rod 11. The movement of the extension rod 2 causes the lithium-ion pruning shears body 3 to move forward, and through the lithium-ion pruning shears body 3, it causes the two reinforcing rods 4 to move forward along the connecting groove 12, thus extending the length of the device to prune branches at higher positions. When the arc-shaped anti-slip sleeve 5 ages or is damaged and needs replacement, the limiting post 8 can be manually pressed inward to move its head from... Once the limiting hole 52 is removed, the arc-shaped anti-slip sleeve 5 can be pulled backward, causing the T-shaped slider 53 to slide out of the T-shaped groove 13. The arc-shaped anti-slip sleeve 5 can then be removed from the handle 1. Next, align the T-shaped slider 53 on the new arc-shaped anti-slip sleeve 5 and slide it into the T-shaped groove 13. Manually press the limiting pin 8 inward, pressing the head of the limiting pin 8 into the limiting groove 14. At this point, the limiting pin 8 can move inward into the limiting groove 14. Compress the spring 9, then pull the front end of the arc-shaped anti-slip sleeve 5, causing the T-shaped slider 53 to slide forward along the T-shaped groove 13 until the T-shaped slider 53 slides to the front end of the T-shaped groove 13. At this time, the limiting hole 52 moves to the limiting post 8. Under the elastic force of the spring 9, the limiting post 8 can pop out and automatically lock into the limiting hole 52, limiting the arc-shaped anti-slip sleeve 5, thus completing the quick replacement of the arc-shaped anti-slip sleeve 5.
