High-cutting-force electric scissors

Abstract

The invention discloses high-cutting-force electric scissors, which comprise a shell. A power supply device and a motor in electrical connection with the power supply device are arranged in the shell,and a shearing mechanism is arranged on the right side of the shell. The electric scissors are characterized in that the shearing mechanism comprises a transmission shaft, a fixed blade and a movableblade, the transmission shaft is connected with the motor, and the movable blade is hinged to the fixed blade which is fixed to the shell; the left side end of the blade is provided with a slide groove, the right side end of the transmission shaft is provided with a gear group, and a connecting rod is fixedly mounted in the center of the gear group and penetratingly inserted in the slide groove through a movable pin. The high-cutting-force electric scissors have advantages that automatic shearing can be realized, the arm of force for driving the movable blade can be gradually increased by means of combination of the connecting rod and the slide groove and reaches a maximum value at the middle position, and the cutting performance is improved.

Description

technical field [0001] The invention relates to agricultural and forestry tools, in particular to electric scissors with high cutting force. Background technique [0002] Electric scissors are relatively common electric tools, which are widely used in garden maintenance, industrial production and other fields. Generally, electric scissors with high cutting force are equipped with battery components and motors electrically connected to the battery components, and the motors are driven by transmission. The shaft is connected with a gear set, and then the fixed blade and the movable blade are connected through the gear set. However, every time the motor rotates forward and reversely, the movable knife performs a shearing operation, but the shearing operation must rely on the repeated positive and negative rotation of the motor. This leads to the phenomenon that the work is not stable enough. Therefore, at this stage, a crank linkage mechanism is used to connect the gear set and...

[0002] Electric scissors are relatively common electric tools, which are widely used in garden maintenance, industrial production and other fields. Generally, electric scissors with high cutting force are equipped with battery components and motors electrically connected to the battery components, and the motors are driven by transmission. The shaft is connected with a gear set, and then the fixed blade and the movable blade are connected through the gear set. However, every time the motor rotates forward and reversely, the movable knife performs a shearing operation, but the shearing operation must rely on the repeated positive and negative rotation of the motor. This leads to the phenomenon that the work is not stable enough. Therefore, at this stage, a crank linkage mechanism is used to connect the gear set and the moving blade. However, during the driving process of this structure, the driving arm is not maintained. change, which also leads to the defect of limited cutting ability
