Problems solved by technology

[0009] However, in the invention described in Patent Document 1, the disconnector is opened when the pressing operation of the switch is released, so that the work efficiency may decrease.
In addition, in order to suppress the reduction in work efficiency, the operator needs to continue to press the switch until the cut-off operation is completed, which imposes a burden on the operator.
Furthermore, in the invention described in Patent Document 2, the forward switch handle and the reverse switch handle are separated, and after the cutoff operation is completed, the operator needs to reset the cutter every time in order to return the cutter to the standby position before the start of the cutoff operation. Set the reverse switch handle to the on state for the first time, thus placing a burden on the operator

Abstract

The electric tool (electric cable cutter (1)) according to the present invention includes: a cutter part (10) for performing a cutting operation; and a cutting operation operation part (20) for starting and stopping the cutting operation and passing the cutting When the operation operation part (20) is turned on, the cutter part (10) is moved toward the end position of the cutting operation, and the operation part (20) is turned off by the cutting operation part (20), so that the If the cutting operation has not been completed, the movement of the cutter part (10) is stopped, and when the cutting operation has been completed at the moment of breaking, the cutter part (10) is moved to the cutting operation. Move in the direction of the standby position before starting.

Description

technical field [0001] The present invention relates to an electric tool, and particularly relates to an electric tool for cutting an object. Background technique [0002] When cutting cables in electrical construction, or cutting steel bars in ironworks, construction sites, etc., hydraulic and battery-type electric tools, specifically electric cable cutters, are used. [0003] In such an electric cable cutter, after the cutting operation is completed, the cutter (blade) used for cutting needs to be returned to the standby position before the cutting operation was started. [0004] In response to this problem, a hydraulic cable cutter has been proposed, which is turned on only while the switch is being pressed, and when the switch is released, the switching valve is automatically switched and the cutter is opened. (For example, refer to Patent Document 1). In addition, a cable cutter with a dust-proof brush has been proposed, which is composed of a forward switch handle th...
