Description

Technical Field

[0001] This utility model belongs to the field of gardening shears technology, and relates to an electric pruning shears for gardening. Background Technology

[0002] Traditional pruning tools have many limitations in garden pruning. Manual pruning shears rely on human power, resulting in low pruning efficiency and operator fatigue. Ordinary electric pruning shears often suffer from signal transmission delays and inaccurate control, leading to deviations in pruning timing. Furthermore, most pruning tools have loose power transmission structures and illogical spatial layouts, increasing overall size, affecting transmission stability, and prone to jamming. In addition, traditional shear blades lack anti-slip design, allowing branches to slip during pruning, reducing pruning accuracy and potentially creating safety hazards.

[0003] Therefore, we propose an electric pruning shears for gardening that can securely clamp and cut branches through precise signal control and compact power transmission. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an electric pruning shears for gardening. The technical problem this utility model aims to solve is: how to enable the pruning shears to achieve stable clamping and cutting of branches through precise signal control and compact power transmission.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An electric pruning shears for gardening includes a housing, a trigger unit, a controller, a power assembly, a fixed blade, and a rotating blade. The housing has an internal mounting cavity. The trigger unit is fixed to the upper end of the mounting cavity, with its trigger extending out of the housing. The controller is fixed to the lower end of the mounting cavity. The power assembly is located inside the mounting cavity. The fixed blade is fixed to the upper end of the power assembly, with its upper end extending out of the upper end of the housing. The rotating blade is rotatably mounted on the fixed blade, with its upper end extending out of the upper end of the housing. The lower end of the rotating blade is connected to the power assembly. Both the trigger unit and the power assembly are electrically connected to the controller. A rechargeable battery pack is detachably mounted at the lower end of the housing.

[0007] The working principle of this utility model is as follows: When the trigger unit is pressed, the trigger unit transmits a signal to the controller, the controller controls the power component to work, the power component drives the rotating blade to rotate on the fixed blade, thereby realizing the cutting action of the tree branch. The fixed blade is fixed on the upper end of the power component and its upper end extends out of the upper end of the outer shell. The rotating blade is rotatably set on the fixed blade and its lower end is connected to the power component for transmission. The entire working process is completed by the controller coordinating the trigger unit and the power component. The rechargeable battery pack is used to provide power.

[0008] The power assembly includes a motor, a mounting plate, a rotating shaft, a drive gear, and a swing gear. The motor is fixed inside the mounting cavity. The mounting plate is vertically mounted on the upper end of the motor. The rotating shaft is horizontally mounted on the mounting plate, and the axis of the rotating shaft is parallel to the axis of the rotating blade. The drive gear is fixed at one end of the rotating shaft, and the other end of the rotating shaft is connected to the output shaft of the motor. The swing gear is fixed at the lower end of the rotating blade and meshes with the drive gear. The fixed blade is detachably fixed to the upper end of the mounting plate.

[0009] With the above structure, when the motor is working, its output shaft drives the rotating shaft to rotate, and the drive gear fixed at one end of the rotating shaft rotates accordingly. Since the oscillating gear meshes with the drive gear, the oscillating gear will oscillate with the rotation of the drive gear, thereby driving the rotating blade to rotate on the fixed blade, and cooperating with the fixed blade to complete the shearing. The mounting plate provides support for the rotating shaft, and the fixed blade is detachably fixed to the upper end of the mounting plate, which facilitates the replacement of worn fixed blade and rotating blade.

[0010] A first bevel gear is fixed on the output shaft of the motor, and a second bevel gear is fixed on the end of the rotating shaft away from the drive gear. The axis of the motor output shaft is perpendicular to the axis of the rotating shaft, and the first bevel gear and the second bevel gear mesh.

[0011] With the above structure, when the motor is working, the first bevel gear fixed on the motor output shaft rotates. Since the first bevel gear and the second bevel gear mesh, and the axis of the motor output shaft is perpendicular to the axis of the rotating shaft, the rotation of the first bevel gear will drive the second bevel gear to rotate, thereby causing the rotating shaft with the second bevel gear fixed to rotate, thus driving the subsequent components to work.

[0012] A central shaft is fixed on the fixed blade, and the middle position of the rotating blade is rotatably sleeved on the central shaft. The specifications of the fixed blade are adapted to the rotating blade, and the rotating blade abuts against the side end face of the fixed blade. Anti-slip teeth are fixed on the cutting edges of both the fixed blade and the rotating blade.

[0013] With the above structure, the rotating blade is rotatably connected to the central shaft sleeved on the fixed blade. Driven by the power component, the rotating blade rotates around the central shaft. Since the specifications of the fixed blade and the rotating blade are compatible and anti-slip teeth are provided on the blade edge, the rotating blade can cooperate with the fixed blade to perform the cutting operation on the branches when it rotates.

[0014] The upper end of the housing has an opening, and the upper ends of the fixed blade and the rotating blade extend out of the upper end of the housing from the opening. A protective ring is fixed on the side wall of the housing, and the position of the protective ring corresponds to the trigger unit. A battery latch is opened at the lower end of the housing, and a contact is fixed inside the battery latch. The specifications of the battery latch and the contact are adapted to the rechargeable battery pack. The upper end of the rechargeable battery pack is detachably set inside the battery latch. A heat dissipation vent is opened on the side wall of the housing, and an anti-slip pad and a switch are fixed on the side wall of the housing. Both the contact and the switch are electrically connected to the controller.

[0015] With the above structure, the fixed blade and the rotating blade extend through the opening at the top of the housing to perform the cutting operation. The protective ring protects the trigger unit and prevents accidental activation. The rechargeable battery pack can be inserted into the housing through the battery clip. The contacts inside the battery clip are connected to the rechargeable battery pack to supply power to the controller, power components, etc. The heat dissipation vent is used for heat dissipation of the equipment. The anti-slip pad is easy to hold. The operation switch can control the opening and closing of the equipment. The contacts and the switch are electrically connected to the controller to realize the corresponding functions.

[0016] Compared with existing technologies, this electric pruning shears for gardening has the following advantages:

[0017] 1. The device achieves signal transmission and control functions through the cooperation of the outer casing, trigger unit, and controller.

[0018] 2. The device achieves power transmission and shearing functions through the cooperation of the outer shell, controller, power component, fixed blade and rotating blade. The fixed blade and rotating blade are equipped with anti-slip teeth, which realizes the stable clamping and shearing of branches and solves the problem of branches slipping during the shearing process.

[0019] 3. By using bevel gear one and bevel gear two to achieve vertical transmission between the motor output shaft and the rotating shaft, the spatial layout problem is solved, resulting in a compact structure and precise transmission. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-4 As shown, this electric gardening pruning shears includes a housing 1, a trigger unit 3, a controller 4, a power assembly 5, a fixed blade 6, and a rotating blade 7. The housing 1 has an internal mounting cavity 2. The trigger unit 3 is fixed to the upper end of the mounting cavity 2, with the trigger of the trigger unit 3 extending out of the housing 1. The controller 4 is fixed to the lower end of the mounting cavity 2. The power assembly 5 is located inside the mounting cavity 2. The fixed blade 6 is fixed to the upper end of the power assembly 5, with the upper end of the fixed blade 6 extending out of the upper end of the housing 1. The rotating blade 7 is rotatably mounted on the fixed blade 6, with the upper end of the rotating blade 7 extending out of the upper end of the housing 1. The lower end of the rotating blade 7 is connected to the power assembly 5 via a transmission mechanism. Both the trigger unit 3 and the power assembly 5 are electrically connected to the controller 4. A rechargeable battery pack is detachably mounted at the lower end of the housing 1.

[0027] In this embodiment, when the trigger unit 3 is pressed, the trigger unit 3 transmits a signal to the controller 4. The controller 4 controls the power component 5 to work. The power component 5 drives the rotating blade 7 to rotate on the fixed blade 6, thereby realizing the cutting action of the tree branch. The fixed blade 6 is fixed on the upper end of the power component 5 and its upper end extends out of the upper end of the outer shell 1. The rotating blade 7 is rotatably set on the fixed blade 6 and its lower end is connected to the power component 5 for transmission. The entire working process is completed by the controller 4 coordinating the trigger unit 3 and the power component 5. The rechargeable battery pack is used to provide power.

[0028] The power assembly 5 includes a motor 8, a mounting plate 9, a rotating shaft 10, a drive gear 11, and a swing gear 12. The motor 8 is fixed inside the mounting cavity 2. The mounting plate 9 is vertically mounted on the upper end of the motor 8. The rotating shaft 10 is horizontally rotatably mounted on the mounting plate 9, and the axis of the rotating shaft 10 is parallel to the axis of the rotating shaft of the rotating blade 7. The drive gear 11 is fixed at one end of the rotating shaft 10, and the other end of the rotating shaft 10 is connected to the output shaft of the motor 8. The swing gear 12 is fixed at the lower end of the rotating blade 7, and the swing gear 12 meshes with the drive gear 11. The fixed blade 6 is detachably fixed on the upper end of the mounting plate 9.

[0029] In this embodiment, when the motor 8 is working, its output shaft drives the rotating shaft 10 to rotate, and the drive gear 11 fixed at one end of the rotating shaft 10 rotates accordingly. Since the oscillating gear 12 meshes with the drive gear 11, the oscillating gear 12 will oscillate with the rotation of the drive gear 11, thereby driving the rotating blade 7 to rotate on the fixed blade 6 and cooperate with the fixed blade 6 to complete the shearing. The mounting plate 9 provides support for the rotating shaft 10, and the fixed blade 6 is detachably fixed to the upper end of the mounting plate 9, which facilitates the replacement of the worn fixed blade 6 and rotating blade 7.

[0030] A bevel gear 13 is fixed on the output shaft of motor 8, and a bevel gear 14 is fixed on the end of rotating shaft 10 away from drive gear 11. The axis of output shaft of motor 8 is perpendicular to the axis of rotating shaft 10, and bevel gear 13 and bevel gear 14 mesh.

[0031] In this embodiment, when the motor 8 is working, the bevel gear 13 fixed on the output shaft of the motor 8 rotates. Since the bevel gear 13 and the bevel gear 14 mesh, and the axis of the output shaft of the motor 8 is perpendicular to the axis of the rotating shaft 10, the rotation of the bevel gear 13 will drive the bevel gear 14 to rotate, thereby causing the rotating shaft 10 fixed with the bevel gear 14 to rotate, thereby driving the subsequent components to work.

[0032] A central shaft 15 is fixed on the fixed blade 6, and the rotating blade 7 is rotatably sleeved on the central shaft 15 at the middle position. The specifications of the fixed blade 6 are compatible with the rotating blade 7. The rotating blade 7 abuts against the side end face of the fixed blade 6, and anti-slip teeth are fixed on the cutting edges of the fixed blade 6 and the rotating blade 7.

[0033] In this embodiment, the rotating blade 7 is rotatably connected to the central shaft 15 sleeved on the fixed blade 6. Driven by the power component 5, the rotating blade 7 rotates around the central shaft 15. Since the specifications of the fixed blade 6 and the rotating blade 7 are compatible and the blade edge is provided with anti-slip teeth, the rotating blade 7 can cooperate with the fixed blade 6 to perform the cutting operation on the tree branch when it rotates.

[0034] An opening 16 is provided at the upper end of the outer casing 1. The upper ends of the fixed blade 6 and the rotating blade 7 extend out of the upper end of the outer casing 1 through the opening 16. A protective ring 17 is fixed on the side wall of the outer casing 1. The position of the protective ring 17 corresponds to the trigger unit 3. A battery latch 18 is provided at the lower end of the outer casing 1. A contact is fixed inside the battery latch 18. The specifications of the battery latch 18 and the contact are compatible with the rechargeable battery pack. The upper end of the rechargeable battery pack is detachably latched inside the battery latch 18. A heat dissipation vent 19 is provided on the side wall of the outer casing 1. An anti-slip pad 20 and a switch 21 are fixed on the side wall of the outer casing 1. Both the contact and the switch 21 are electrically connected to the controller 4.

[0035] In this embodiment, the fixed blade 6 and the rotating blade 7 extend through the opening 16 at the upper end of the housing 1 to perform a cutting operation. The protective ring 17 protects the trigger unit 3 to prevent accidental activation. The rechargeable battery pack can be inserted into the housing 1 through the battery clip 18. The contacts in the battery clip 18 are connected to the rechargeable battery pack to supply power to the controller 4, power component 5, etc. The heat dissipation vent 19 is used for heat dissipation of the device. The anti-slip pad 20 is convenient for hand gripping. The operation switch 21 can control the opening and closing of the device. Both the contacts and the switch 21 are electrically connected to the controller 4 to realize the corresponding functions.

[0036] The working principle of this utility model is as follows: When the trigger unit 3 is pressed, the trigger unit 3 transmits a signal to the controller 4. The controller 4 controls the power assembly 5 to work. In the power assembly 5, the motor 8 drives the bevel gear 13 on the output shaft to rotate. Since the bevel gear 13 meshes with the bevel gear 14 on the rotating shaft 10, and the axis of the output shaft of the motor 8 is perpendicular to the axis of the rotating shaft 10, the rotation of the bevel gear 13 drives the bevel gear 14 to rotate, causing the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the drive gear 11 fixed at one end to rotate. The oscillating gear 12 meshing with the drive gear 11 oscillates accordingly, thereby driving the rotating blade 7 to rotate around the central axis 15 on the fixed blade 6, thus achieving the cutting of branches. The operation involves a fixed blade 6 fixed to the upper end of a mounting plate 9, which provides support for a rotating shaft 10. The fixed blade 6 and the rotating blade 7 extend through an opening 16 at the upper end of the housing 1 for shearing. A protective ring 17 protects the trigger unit 3. A rechargeable battery pack is inserted into the housing 1 through a battery clip 18. The contacts in the battery clip 18 are connected to the rechargeable battery pack to supply power to the controller 4, power assembly 5, etc. A heat dissipation vent 19 is used for heat dissipation of the equipment. An anti-slip pad 20 facilitates hand grip. An operating switch 21 controls the opening and closing of the equipment. Both the contacts and the switch 21 are electrically connected to the controller 4 to achieve the corresponding functions. The entire working process is completed by the controller 4 coordinating the trigger unit 3 and the power assembly 5.

[0037] In summary, the signal transmission and control functions of the device are realized through the cooperation of the outer casing 1, the trigger unit 3 and the controller 4.

[0038] The device achieves power transmission and shearing functions through the cooperation of the outer shell 1, controller 4, power component 5, fixed blade 6 and rotating blade 7. Anti-slip teeth are provided on the fixed blade 6 and rotating blade 7 to achieve stable clamping and shearing of branches, thus solving the problem of branch slippage during the shearing process.

[0039] By cooperating with bevel gear 13 and bevel gear 2, vertical transmission between the output shaft of motor 8 and rotating shaft 10 is achieved, solving the spatial layout problem and making the structure compact and the transmission precise.
