Electric fence shears with movable power components

This creation relates to an electric fence shear, in particular an electric fence shear with a mobile power assembly.

Currently, fence shears commonly found on the market generally include a power and cutting assembly and a grip assembly. The power and cutting assembly is mainly composed of a motor and a blade. The motor can drive the blade to vibrate back and forth, thereby achieving the purpose of trimming the fence through the vibration of the blade.

Please refer to the hedge trimmer of the application of the new style patent publication No. D112185. Referring to the first figure, a perspective view of a conventional fence shear. As shown in the first figure, in order to allow the user to operate the fence shear 1a stably while the fence shear 1a vibrates, the grip assembly generally includes the front grip portion 11a and the rear grip portion 13a for use. At the same time, the front grip portion 11a is fixed to the front end of the rear grip portion 13a so as to be perpendicular to the rear grip portion 13a, and the front grip portion 11a and the rear grip portion 13a are They are connected to the front side and the rear side of the motor 3a, respectively.

It should not be overlooked that the center of gravity and balance of the hedge shear 1a are constantly changing when flipping, so the operator must also struggle to maintain its center of gravity and balance, in case the operator does not actually hold the fence shear 1a, except for the fence shears. Damaged by impact on the ground is a major threat to personnel safety. Further, since the front grip portion 11a and the rear grip portion 13a are coupled to the opposite sides of the motor 3a, the operator must pay a horizontal force to bear the weight of the fence shear 1a and the center of gravity of the fence shear 1a.

In addition, the conventional grip member of the fence shear and the power and the cutting assembly are connected to each other only through a single rotating shaft, thereby not only greatly reducing the structure of the fuselage. Rigidity also reduces the stability of the fuselage due to the vibration generated by the motor when the fence shears operate.
