[0028] Example 1

[0029] Reference Figure 1-4 As shown in the figure, this embodiment proposes a lithium-electric cutting device, which improves the traditional long-handled manual pliers into lithium-electric metal pliers. It has a compact and lightweight appearance, flexible and labor-saving operation, can be used for wire rope cutting, cable cutting and steel bar cutting, and can trim steel bars within 10mm and ordinary metal materials.

[0030] Specifically, the lithium-ion battery cutting device includes a shearing unit, a transmission unit and a control unit. The shearing unit's shears are used to cut wire ropes, cables and steel bars. The transmission unit is used to transmit the torque output by the motor to the shearing unit for cutting. The control unit is used to control the magnitude of the torque output by the motor.

[0031] Furthermore, the shearing unit includes a fixed blade 6, a movable blade 7, and a swinging tooth 10, which are sequentially arranged on one side of the aluminum shell 5. The fixed blade 6 and the movable blade 7 are attached and hinged, and the fixed blade 6 and the aluminum shell 5 cannot rotate, and the movable blade 7 and the swinging tooth 10 cannot rotate. The fixed blade 6 and the movable blade 7 are connected to the aluminum shell 5 by a hexagon socket head anti-drop screw 2 and a stop washer 3, and the fixed blade 6 is limited to the aluminum shell 5 by a stop nut 4, and the swinging tooth 10 is embedded in the movable blade 7 by a limit pin and fixed by a locking screw 11. It should be noted that since the fixed blade 6 is doubly fixed by the stop nut 4 and the hexagon socket head anti-drop screw 2, the fixed blade 6 cannot rotate relative to the aluminum shell 5, which plays a limiting role.

[0032] The transmission unit includes a bevel gear 12, a bearing 13, a Z45 gear ring 15, and a brushless motor 21, which are arranged in sequence from top to bottom. The Z45 gear ring 15 is connected to the aluminum shell 5 and the brushless motor 21 through threads at the top and bottom. The bevel gear 12 and the bearing 13 are both arranged in the Z45 gear ring 15. The brushless motor 21 transmits kinetic energy to the bevel gear 12 through the bearing 13. The swing gear 10 cooperates with the bevel gear 12 gear. The transmission unit also includes an internal retaining spring 14, an output shaft frame 16, steel planetary gears 16 and 17, a secondary gear frame 18, a powder primary planetary gear 19, and a motor gear 20, which are arranged in sequence downward. There are two secondary gear frames 18, and the motor gear 20 is connected to the output shaft of the brushless motor 21. The brushless motor 21 of this embodiment transmits torque to the bevel gear 12 through a transmission structure. For this transmission structure, reference can be made to the transmission of existing lithium electric shears. It is a relatively mature technical means in this field and will not be described in detail here.

[0033] The control unit includes a control board 27, which is connected to the brushless motor 21 and is used to control the rotation of the brushless motor 21. It also includes a T1 board 28-1 and a T2 board 28-3 respectively arranged above and below the cylindrical pin 26, and a T3 board 28-2 connected to the other end of the T2 board 28-3. It also includes a US-style bracket 30, which is connected to the control board 27 via a first lead 28 and a second lead 29. Similarly, the control board 27 is actually a circuit board, and the T1 board 28-1, T2 board 28-3, and T3 board 28-2 are all circuit boards. The entire circuit control of the lithium-ion shearing device can be achieved by referring to existing mature technologies, including the wiring and installation of its circuits and electronic components in the housing. Those skilled in the art can refer to the existing mature technology of lithium-ion shears for implementation, which will not be described in detail here.

[0034] Furthermore, the lithium battery cutting device proposed in this embodiment also includes a left housing 1, a right housing 31, a cover plate 32, a follower button 22, a follower spring 23, a power-on button 24, a power-on spring 25, a cross-slotted semicircular head screw 8, and a permanent magnet 9. Specifically, the left housing 1 and the right housing 31 are covered to form an installation cavity, and the transmission unit and the control unit are both arranged in the installation cavity. The power-on button 24 and the power-on spring 25, the power-on button 24 is a power switch, which is used to connect and disconnect the power required for the circuit of the entire device. The follower button 22 is connected to the control board 27 and can be used to control the start and stop of the brushless motor 21 after the entire device is powered on. The permanent magnet 9 is installed on the swing tooth 10, and the cross-slotted semicircular head screw 8 is used to install the T1 plate 28-1. The electrical connection of the follower trigger 22 and the power-on trigger 24, as well as how to power on and how to start, are all very existing technologies. Those skilled in the art can fully implement this solution by referring to the existing lithium electric shears, and the power-on spring 25 and the follower spring 23 play the role of button rebound.

[0035] It should be noted that the core concept of the lithium-ion cutting device proposed in this embodiment is to improve the traditional long-handled manual pliers into lithium-ion metal pliers. By improving the material hardness and transmission ratio of the pliers body, it can be used for wire rope cutters, cable cutters and steel bar cutters, and can trim steel bars within 10 mm and ordinary metal materials. Combined with the existing lithium-ion shears for cutting branches, those skilled in the art should understand that the control unit of the device itself, and the installation, wiring, circuits of the electrical components involved, how to achieve motor control, motor torque control, and circuit control of the follow-up trigger 22 and the power-on trigger 24, etc., all belong to existing mature technologies, and are not necessary technical features for the technical problems to be solved by the technical solution proposed in this embodiment. Those skilled in the art can refer to the existing technology for full implementation. They are non-essential technical features and are therefore not described in detail.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The embodiments should be considered as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference signs in the claims should not be construed as limiting the claims to which they relate.

[0037] It should also be understood that the present invention is described through implementation methods, and the embodiments are only clear and complete descriptions of the technical solutions proposed in the claims of the present invention, that is, explanations of the claims. Therefore, when judging whether the technical solutions recorded in the description of the present invention are sufficiently disclosed, full consideration should be given to the core essence of the solutions defined by the claims. In the description, there must be other technical problems that are not related to the core technical problems proposed by the embodiments. The corresponding technical features and technical solutions do not belong to the essence of the embodiments and are non-essential technical features. Therefore, they can be referred to as implicit disclosures. Those skilled in the art can fully implement them in combination with existing technologies and common knowledge.
