According to the general electric garden shears (fruit tree shears), the motor is used to control the cutting tool to open and close to achieve the purpose of cutting. However, the opening angle of the shearing tool of the electric shearing cutter is fixed. Therefore, if the opening angle of the shearing cutter is large, the user tends to damage the fruit because the opening angle is too large when the fruit is harvested; When the opening angle of the cutting tool is small, the branch trimming cannot be performed.
