- the cutting operation operation unit 20B is turned off, and when the cutting operation is completed at the time of turning off, the cutting operation is performed on the cutter unit 11 with a movement amount selected from a plurality of movement amounts set. Move toward the standby position before starting.
- the electric cable cutter 1B can perform the cutting operation of the cutter unit 11 even if the cutting operation operating unit 20B is turned off before the cutting operation of the cutting object 2A is completed. Since the movement in the direction of the end position stops and the cutter unit 11 does not move in the direction of the standby position before the start of the cutting operation, the above-described reduction in work efficiency can be suppressed. In addition, since the electric cable cutter 1B automatically moves toward the standby position before the cutting operation starts after the cutting operation is completed, the operator returns the cutter to the standby position before the cutting operation starts. Therefore, it is not necessary to turn the reverse switch lever on every time. Therefore, the burden on the operator can be reduced.
- the electric cable cutter 1B which concerns on the 3rd aspect of the electric tool of this invention is set with two or more said return amounts so that switching is possible, it selects a preferable return amount according to the cutting condition of the cutter part 11. FIG. Can do. Therefore, since the electric tool can be provided with versatility, it is possible to further suppress a decrease in work efficiency. In addition, it is not necessary for the operator to return to the optimum position every time with the reverse switch lever or the like and to return automatically to the optimum position, so that the burden on the operator can be further reduced.
- the drive mechanism by turning on (preferably pushing) the cutting operation operation unit 20B, the drive mechanism is driven, and the cutter unit 11 moves toward the end position of the cutting operation. Further, by turning off the cutting operation operation unit 20B (preferably releasing the push-in operation), if the cutting operation is not completed at the time of turning off, the driving of the drive mechanism is stopped (specifically, the storage battery cartridge 60A). Is stopped), the movement of the cutter unit 11 toward the end position of the cutting operation is stopped. Further, when the cutting operation is finished when the cutting operation operation unit 20B is turned off, the cutter unit 11 is moved in the standby position direction before the cutting operation is started by rotating the electric motor of the driving mechanism in the reverse direction.
- a plurality of movement amounts to be moved and moved in the standby position direction B are set to be selectable.
- the cutter is rotated with the movement amount selected from a plurality of movement amounts by reversely rotating the electric motor of the drive mechanism.

Note that various controls relating to the cutting operation of the electric cable cutter 1B described below are performed, for example, according to instructions from a control unit (control circuit, processor, etc.) (not shown) provided in the electric cable cutter 1B.
- a control unit control circuit, processor, etc.
- the cutter unit 11 moves from the standby position before starting the cutting operation toward the end position of the cutting operation, and is to be cut.
- the product 2A is cut (S701).
- the end of the cutting operation of the cutting object 2A is detected (S702).
- the movement of the cutter unit 11 toward the end position of the cutting operation is stopped (S703).
- it is determined whether or not the cutting operation unit 20B (the switch unit in FIG. 13 is the same hereinafter) is turned off (S704).
- an amount (movement amount) for moving the cutter unit 11 toward the cutting operation standby position is selected (S705). Based on the selected movement amount, the cutter unit 11 is moved toward the standby position before the start of the cutting operation (S706). Further, when it is determined that it is not turned off in S704 (in the case of “No” in FIG. 13), S703 (stopping the movement of the cutter unit 11) is continued until the cutting operation unit 20B is turned off. On the other hand, if the end of the cutting operation of the cutting object 2A is not detected in S702 (in the case of “No” in FIG.
- S707 it is next determined whether or not the cutting operation operation unit 20B is turned off (S707). ) In S707, when it is determined that the cutting operation unit 20B is turned off (in the case of “Yes” in FIG. 13), the movement of the cutter unit 11 toward the end position of the cutting operation is stopped (S708). If it is determined in S707 that the cutting operation unit 20B is not turned off ("No" in FIG. 13), the cutting of the cutter unit 11 is detected until the end of the cutting operation in S702 is detected. Continue moving toward the end position of the motion.
- FIG. 14 is a conceptual diagram illustrating an example of detection of the end of the cutting operation of the electric cable cutter 1B according to the present embodiment.
- the end of the cutting operation of the electric cable cutter 1B is detected by operating the electric motor by detecting the start of cutting and the end of cutting of the cutting object 2A by the cutter unit 11. This is done by detecting the value of the motor load current, which is a current. That is, the cutting start is detected when the cutting of the cutting object 2A by the cutter unit 11 is started when the motor load current is equal to or greater than a predetermined value (or within a predetermined range) at the start of cutting or after the start of cutting. To do.
- the end of cutting is detected when the cutting of the cutting object 2A by the cutter unit 11 is completed when the motor load current is equal to or less than a predetermined value (or within a predetermined range). Then, when the end of the cutting operation is detected, it is determined that the end of the cutting operation is detected in S702 of FIG. 13 when both the start of cutting and the end of cutting are detected.
- the amount of movement (movement amount) for moving the cutter unit 11 of the present embodiment toward the cutting operation standby position is selected when the cutting operation operation unit 20B (switch unit in FIG. 13) is turned off. As described above, the movement amount may be selected before the cutter unit 11 moves toward the cutting operation end position (S701).
