Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to an electric fish-killing toothed knife with a mechanical button protection device. Background Technology

[0002] Electric fish knives are electrically powered tools for cutting and processing fish, improving processing efficiency and allowing for faster cutting or processing of large fish. They are widely used in Europe and America. However, existing electric fish knives lack a safety locking function, leading to accidental activation during storage and transportation. This can waste energy, damage the knife, or, in severe cases, cause safety accidents.

[0003] Currently, there are many types of electric fishing knife protection devices. Common electric fishing knife protection devices include telescopic or fixed protective covers, and those that use spring structures to lock the blade at the end when the power is off. Although these devices can all protect the electric fishing knife from accidental activation in a certain way, their structures are relatively complex. Therefore, there is an urgent need to research an electric fishing knife with an anti-accidental activation function to improve safety during storage, transportation and use, and avoid safety accidents caused by accidental activation. Utility Model Content

[0006] The left and right housings are assembled together with M4 Phillips head screws to form the handle frame of the electric fish-killing knife. A motor module and a circuit module are installed inside the handle frame. The input end of the motor module is connected to the circuit module, and the output end is equipped with a transmission device. The blade is mounted on the transmission device, which drives the two blades of the blade to reciprocate, achieving the cutting function. The battery is connected to the circuit module to provide power. The button device is connected to the circuit module to control the operation of the motor module. The button device is equipped with a mechanical button protection device to lock the button device.

[0007] The left and right casings are respectively provided with a left leather sleeve, a left heat dissipation mesh, a left heat dissipation mesh fixing aluminum sheet, a left front fixing aluminum sheet, a right leather sleeve, a right heat dissipation mesh, a right heat dissipation fixing aluminum sheet, and a right front fixing aluminum sheet. An upper rubber sheet is provided above the connection between the left and right casings. The left leather sleeve, right leather sleeve, and upper rubber sheet are ergonomically designed.

[0008] Furthermore, the motor module includes a worm gear, an M3 screw, a motor connector, a brushless motor, and a turbo fan;

[0009] The turbine fan is connected to the brushless motor to provide airflow for cooling the brushless motor; the worm gear is installed at the output end of the brushless motor and connected to the transmission device to provide power to the transmission device; the motor connector is fixed to the brushless motor with M3 screws to install the transmission device and the motor module together.

[0010] Furthermore, the transmission device includes a left bending spring latch, a right bending spring latch, a left sliding groove housing, a right sliding groove housing, a helical gear, a fixed shaft, and a transmission fixed housing;

[0011] The left and right sliding groove shells are slidably installed in the slots on the left and right sides of the transmission fixed shell, respectively. The left and right bending spring locks are installed in the slots of the left and right sliding groove shells, respectively. A helical gear is installed at the center of the fixed shaft. Eccentric wheels with a 180° difference in eccentricity are set on both sides of the helical gear. The two ends of the fixed shaft are installed in the slots on the motor connecting seat. The two eccentric wheels with a 180° difference in eccentricity are respectively engaged in the slots of the left and right sliding groove shells, driving the left and right sliding groove shells to move relative to each other, thereby realizing the reciprocating motion of the blade.

[0012] Furthermore, the cutting edge includes a left blade, a right blade, a left fixing block, a right fixing block, and a sliding screw;

[0013] The left and right fixing blocks are respectively installed on the left and right blades for installing and removing the left and right blades, avoiding scratches caused by direct contact between the blades and the hands; the left blade is provided with a mounting hole for a sliding screw, and the right blade is provided with a corresponding slide rail, using the sliding screw to slide the left and right blades together, so as to realize relative movement between the left and right blades in the same slide rail.

[0016] Furthermore, the latching device includes a latch and a spring;

[0017] One end of the spring is fixed to the left housing, and the other end is hooked in the slot of the buckle. When the buckle device is pushed to the rear of the handle, the buckle device presses the bending spring lock downward, causing the oblique groove on the blade to disengage from the slot on the bending spring lock, thereby realizing the disassembly function; the blade is directly inserted into the slot on the bending spring lock through the oblique groove on the bending spring lock, thereby installing the blade onto the transmission device.
