[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a reinforced aluminum component structure for lithium-ion battery pruning shears. Through the mutual cooperation between the spur gear, spur gear, spur gear bearing, auxiliary bevel gear, main bevel gear, and bevel gear bearing, the power transmission structure of the lithium-ion battery pruning shears has been innovatively improved. The traditional mode of direct interaction between the bevel gear and the spur gear has been transformed into a mode where the main bevel gear drives the auxiliary bevel gear to rotate, which in turn drives the spur gear to move. This design ensures that the compressive force released laterally by the main bevel gear only acts on the auxiliary bevel gear, while the spur gear is responsible for driving the movement of the spur gear. Since the spur gear only applies radial force to the spur gear, the force is evenly distributed, effectively extending the service life of the shears.

By fully embedding the gear transmission system inside the aluminum structure, the coverage of the aluminum material on the gear is significantly improved. This design not only innovates the traditional aluminum structure, but also increases the volume of the aluminum body itself, thereby enhancing the overall strength of the structure. In addition, the larger coverage space ensures the stability of the structure, making the whole structure more robust and durable. Attached Figure Description

Detailed Implementation

[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0026] like Figure 1 , Figure 2 , Figure 5 As shown, this utility model provides a reinforced structure for aluminum parts of lithium-ion pruning shears, including a pruning shear main frame 1, a reinforcing structure 2 at the top of the pruning shear main frame 1, and a battery 3 at the bottom of the pruning shear main frame 1. The pruning shear main frame 1 includes a housing 11, which is located on top of the battery 3. A motor 12 is fixedly installed below the inner surface of the housing 11, and a planetary gearbox 13 is fixedly installed above the inner surface of the housing 11. The input end of the planetary gearbox 13 is fixedly connected to the output end of the motor 12. The inner surface of the top of the planetary gearbox 13 is threadedly connected to the outer surface of the bottom of the aluminum body structure 21. The output end of the planetary gearbox 13 is fixedly connected to the main bevel gear 29. A wrench 14 is movably connected to the upper right side of the housing 11, and the top of the wrench 14 is movably connected to the right side of the aluminum body structure 21. The bottom of the housing 11 is fixed. A battery connection plate 17 is connected, and the top of the battery 3 is slidably snapped into the bottom of the battery connection plate 17. An electric control switch 16 is fixedly installed on the top of the battery connection plate 17. A PCB board 15 is set on the top of the electric control switch 16. The front end of the PCB board 15 extends through to the lower front side of the outer surface of the pruning shears frame 1. Vertical slots 171 are opened on the left side of both the front and rear sides of the battery connection plate 17. Pressing posts 31 are slidably inserted into the top left side of both the front and rear sides of the battery 3. The pressing posts 31 extend into the interior of the battery 3 and are fixedly connected to vertical plates 32. The right end of the vertical plates 32 is slidably snapped into the inner wall of the vertical slots 171. Two horizontal slots 172 are opened on the top left side of the battery connection plate 17. Horizontal plates 33 are fixedly connected to the front and rear sides of the top left side of the battery 3. The horizontal plates 33 are slidably snapped into the interior of the horizontal slots 172.

[0027] When using lithium-ion pruning shears, the battery 3 is slid into the battery connecting plate 17, causing the vertical clamping plate 32 to engage with the vertical clamping slot 171 and the horizontal clamping plate 33 to engage with the horizontal clamping slot 172, thus connecting and fixing the battery 3. The battery 3 can be powered by the electric control switch 16. By pulling the wrench 14, the motor 12 is activated, and under the transmission of the planetary gearbox 13, it can drive the reinforcing structure 2 to prune the branches.

[0028] like Figure 3 , Figure 4As shown, this utility model provides a reinforcing structure for aluminum components of lithium-ion pruning shears. The reinforcing structure 2 includes an aluminum body structure 21, which is fixedly installed on the top of the pruning shear main frame 1. A connecting pin 22, which passes through the front and rear, is movably connected to the top of the aluminum body structure 21. A fixed blade 23 is provided on the front side of the outer surface of the connecting pin 22. The fixed blade 23 is fixedly installed on the upper rear side of the aluminum body structure 21. A rotating blade 24 is rotatably connected to the rear side of the outer surface of the connecting pin 22. A swing tooth 25 is fixedly connected to the bottom end of the rotating blade 24, and the bottom of the swing tooth 25 is engaged with the... There is a spur gear 26, which is movably connected inside the aluminum body structure 21. A spur gear bearing 27 is fixedly connected to the rear side of the spur gear 26. The spur gear bearing 27 is fixedly installed inside the rear side of the aluminum body structure 21. A secondary bevel gear 28 is fixedly connected to the front end of the spur gear 26. A main bevel gear 29 is meshed with the bottom of the secondary bevel gear 28. The main bevel gear 29 is rotatably connected to the lower part of the interior of the aluminum body structure 21. A bevel gear bearing 210 is fixedly connected to the bottom of the main bevel gear 29. The bevel gear bearing 210 is fixedly installed on the bottom end of the inner surface of the aluminum body structure 21.

[0029] By using a main bevel gear 29 to drive the secondary bevel gear 28 to rotate, and the secondary bevel gear 28 to drive the spur gear 26 to move, the compressive force released by the main bevel gear 29 to the side only acts on the secondary bevel gear 28. The spur gear 26 drives the swivel tooth 25 to move, and the spur gear 26 only exerts a radial force on the swivel tooth 25, making the force more even and extending its service life. By setting all gear transmissions inside the aluminum body structure 21, the coverage area of ​​the aluminum body on the gears is increased, the strength of the aluminum body structure is enhanced, the coverage space is expanded, and it is made more robust.

[0030] The working principle of the lithium battery pruning aluminum reinforcement structure will be explained in detail below.

[0031] like Figure 1-5 As shown, when using lithium-ion pruning shears, slide the battery 3 into the battery connecting plate 17, ensuring that the vertical clamping plate 32 and the horizontal clamping plate 33 are respectively engaged in the corresponding vertical clamping slot 171 and horizontal clamping slot 172 to achieve a stable connection of the battery 3. By operating the electronic control switch 16, the battery 3 can be controlled to supply power to the motor 12. Then, the wrench 14 is pulled to start the motor 12. The operation of the motor 12 drives the main bevel gear 29 to rotate through the transmission action of the planetary gearbox 13. The rotation of the main bevel gear 29 drives the spur gear 26 through the secondary bevel gear 28, which in turn drives the spur gear 26 to move the oscillating tooth 25. The movement of the oscillating tooth 25 ultimately controls the rotating blade 24 to rotate around the connecting pin 22, working in conjunction with the fixed blade 23 to complete the pruning of the branches.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
