Problems solved by technology

[0004] The joystick exhibits an oscillating motion about its hinge axis, thus creating an unpleasant relative movement between the user's fingers and the joystick
Furthermore, relatively imprecise, unstable control is obtained by means of the actuation via the sensor integrated in the transmission element, so that the user feels that the actuation of the scissors is clumsy

Embodiment Construction

[0022] exist figure 1 The electric scissors shown in are configured as pruning shears, pruning shears, garden shears or similar; such scissors 1 are used, for example, in gardens or vineyards. The scissors 1 essentially comprise a housing 3 which is simultaneously designed as a handle. Scissors blades 5 and 6 are arranged in the region of the head 4 . In the embodiment shown, the blade 6 is fixed; the blade 5 pivots relative to the blade 6 about a blade axis 7 .

[0023] The shears 1 or pruning shears 2 are electric shears, suitably powered by a battery pack not shown. as from according to figure 2 As can be seen in the side view of the scissors 1 , an electric drive motor 8 is accommodated in the housing 3 of the scissors 1 , which is controlled by a control unit 9 . The motor shaft 10 drives a main shaft, on which a transmission element 11 is screwed. The transmission element 11 is connected to the movable blade 5 so that the blades 5 and 6 open in one direction of rot...

Abstract

The invention relates to electric shears, and particularly to electrical shears have a housing (3) and an electric drive motor (8). The electric drive motor operates at least one blade (5,6) of branch trimming shears (2) through a motor shaft (10) for closing and opening. The electric drive motor (8) is controlled by an electric adjusting signal of a control unit (9), wherein the electric adjusting signal describes a mechanical position of a manual operating component (12) of the branch trimming shears (2). For opening and closing the blades by a user flexibly, a control unit (12) is arranged for guiding and is provided with a guiding member (22) that extends along a straight adjusting path.

Description

technical field [0001] The invention relates to an electric scissors, in particular pruning scissors, pruning scissors, garden scissors, etc., according to the preamble of claim 1 . Background technique [0002] From document EP 0 291 431 B1 a pruning shear is known, in whose housing an electric drive motor is arranged. The blades of the scissors are actuated for closing and opening via the motor shaft of the drive motor, for which the drive motor is actuated in dependence on the electrical regulation signal of the control unit. [0003] The drive shaft connected to the blade is driven by the motor shaft. An actuation lever is pivotally articulated on the drive shaft, wherein a position sensor is arranged between the drive shaft and the actuation lever. If the user depresses the joystick, the position sensor is deflected from its rest position, and to compensate for the deflection, the electric motor is run in such a direction of rotation that the transmission element on t...
