Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, and in particular relates to a lightweight, detachable electric scissors. Background Technology

[0002] Electric shears are a type of cutting tool driven by an electric motor. Through mechanical transmission, they reduce the burden of manual operation and wrist fatigue. They also boast advantages such as powerful motors and long continuous working time, and can cut various materials including metal sheets, branches, and fabrics, meeting the needs of different scenarios. They are widely used in the automotive, shipbuilding, and horticulture industries.

[0003] However, most electric scissors on the market have their power system and operating system fixed together, making them quite heavy. Prolonged use can cause wrist and arm pain, affecting work efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing electric scissors by providing a detachable electric scissors that can effectively reduce the weight during use and decrease the workload.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A detachable electric shears unit includes a shears body and a power system, wherein the power system drives the shears body to move. The key feature is that the shears body and the power system are separately configured and connected via a flexible power transmission mechanism and a signal transmission cable. By separating the heavy power system from the shears body and transmitting power and control signals through the flexible power transmission mechanism and signal transmission cable, the operator only needs to hold the shears body for cutting operations, greatly reducing workload and improving work efficiency.

[0007] A further feature is that the scissors body includes a fixed blade, a movable blade, and a cutting control handle; the power system includes a battery, a controller, a motor, and a reducer; the cutting control handle is electrically connected to the controller via the signal transmission cable. The cutting control handle sends a cutting signal to the controller, which controls the battery to power the motor to rotate, and outputs rotational torque through the reducer, which then drives the movable blade to rotate through a flexible power transmission mechanism, working in conjunction with the fixed blade to achieve the cutting action.

[0008] One configuration: The power transmission mechanism consists of two steel wire conduits, or steel wires or hydraulic hoses, connected to a movable cutter head, driving the movable cutter head to open and close for shearing. The movable cutter head is driven to rotate through the differential action of the two steel wire conduits, or steel wires or hydraulic hoses.

[0009] Preferably, the reducer is connected to a bevel gear set, the first bevel gear is connected to the output shaft of the reducer, and one end of the power transmission mechanism is connected to the second bevel gear; a rotating wheel is provided on the scissor body, and the other end of the power transmission mechanism is connected to the rotating wheel; the rotating wheel drives the movable cutter head to rotate and open. Two steel wire conduits, or steel wires or hydraulic oil pipes, transmit the rotation of the second bevel gear to the rotating wheel, driving the movable cutter head to rotate.

[0010] Another form: the power transmission mechanism is a universal flexible shaft.

[0011] Preferably, the output shaft of the reducer is connected to one end of the universal flexible shaft, and the other end of the universal flexible shaft is connected to the first bevel gear of the bevel gear set on the scissor body; the second bevel gear is disposed on the movable cutter head, driving the movable cutter head to rotate and open.

[0012] This invention separates the heavy power system from the scissor body, and transmits power and control signals through a flexible power transmission mechanism and signal transmission cable. The operator only needs to hold the scissor body to perform the cutting operation, which greatly reduces the workload and improves work efficiency. Attached Figure Description

[0013] Figure 1 is a schematic diagram of Embodiment 1 of this utility model.

[0014] Figure 2 is a schematic diagram of Embodiment 2 of this utility model. Detailed Implementation

[0015] Example 1:

[0016] like Figure 1 As shown, a detachable electric scissors includes a scissor body and a power system, the power system driving the scissor body to move. The scissor body includes a fixed blade head 12, a movable blade head 10, and a cutting control handle 9. The power system includes a battery 1, a controller 2, a motor 3, and a reducer 4. The cutting control handle 9 is electrically connected to the controller 2 via a signal transmission cable 7. The reducer 4 is connected to a bevel gear set, a first bevel gear 5 is connected to the output shaft of the reducer 4, and two steel wire tubes 8 are connected to both sides of the second bevel gear 6. The movable blade head 10 is located on a rotating wheel 11, and the other ends of the two steel wire tubes 8 are connected to both sides of the rotating wheel 10.

[0017] When the electric shears are in operation, the shearing control handle 9 sends a shearing signal to the controller 2 via the signal transmission cable 7. The controller 3 controls the battery 1 to power the motor 3 to rotate, and outputs rotational torque through the reducer 4, driving the first bevel gear 5 and the second bevel gear 6 to rotate. The rotation of the second bevel gear 6 drives the two steel wires 8 to move differentially, synchronously driving the rotating wheel 11 to rotate, and driving the movable cutter head 10 to rotate, working together with the fixed cutter head 12 to achieve the shearing action.

[0018] Example 2:

[0019] like Figure 2 As shown, a detachable electric scissors includes a scissor body and a power system, the power system driving the scissor body to move. The scissor body includes a fixed blade head 12, a movable blade head 10, and a cutting control handle 9. The power system includes a battery 1, a controller 2, a motor 3, and a reducer 4. The cutting control handle 9 is electrically connected to the controller 2 via a signal transmission cable 7. The output shaft of the reducer 4 is connected to one end of a universal flexible shaft 13, and the other end of the universal flexible shaft 13 is connected to the first bevel gear 5 of the bevel gear set on the scissor body; the second bevel gear 6 is mounted on the movable blade head 10.

[0020] When the electric shears are in operation, the shearing control handle 9 sends a shearing signal to the controller 2 via the signal transmission cable 7. The controller 3 controls the battery 1 to power the motor 3 to rotate, and outputs rotational torque through the reducer 4. This torque is then driven by the universal flexible shaft 13 to rotate the first bevel gear 5 and the second bevel gear 6. The second bevel gear 6 drives the movable cutter head 10 to rotate, working in conjunction with the fixed cutter head 12 to achieve the shearing action.

[0021] This invention separates the heavy power system from the scissor body, allowing the operator to simply hold the scissor body for cutting operations, greatly reducing workload and improving efficiency.
