Abstract: An electric cutting device includes: a pair of cutting blades configured to clamp and cut an object; an electric motor configured to generate a driving force necessary for operating the cutting blades; and a guide plate formed with a recess configured to house the object in advance when the object is cut by the pair of cutting blades. The guide plate is formed such that a width of the recess decreases from an open end side toward an inner side of the recess.

Abstract: An electric cutting device includes: a pair of cutting blades for clamping and cutting an object; an electric motor; and a drive mechanism for operating the cutting blades. The drive mechanism includes a movement member movable in a predetermined direction by a driving force of the electric motor and converts movement of the movement member into an opening and closing operation of the cutting blades. The drive mechanism is configured to: when the movement member moves in the predetermined direction, cause the pair of cutting blades to move in a direction closer to each other; and after the pair of cutting blades come closest to each other, when the movement member further moves in the predetermined direction, cause the pair of cutting blades to move in a direction away from each other.

Abstract: An electric cutting device includes: a pair of cutting blades configured to clamp and cut an object; an electric motor configured to generate a driving force necessary for operating the cutting blades; a controller configured to control an operation of the electric motor; an operation device configured to be switched between an ON state and an OFF state by a user operation; and a detector configured to: enter into an ON state in a case where the object is present between the pair of cutting blades; and enter into an OFF state in a case where the object is not present. The controller is configured to execute an operation of closing the pair of cutting blades in a case where both the operation device and the detector are in the ON state.

Abstract: An electric cutting device includes a pair of cutting blades configured to clamp and cut an object, an electric motor configured to generate a driving force necessary for operating the cutting blades, a controller configured to control an operation of the electric motor, and a speed detector configured to detect a speed index, the speed index indicating an operation speed of the cutting blades. The controller is configured to brake the cutting blades based on the speed index.

Abstract: An electric cutting device includes: a pair of cutting blades configured to clamp and cut an object; an electric motor configured to generate a driving force necessary for operating the cutting blades; and a guide plate formed with a recess configured to house the object in advance when the object is cut by the pair of cutting blades. The guide plate is configured to be switched between: a first state where a front end of the guide plate protrudes further than a front end of each cutting blade; and a second state where the front end of the cutting blade protrudes further than the front end of the guide plate.

Abstract: An electric cutting device includes: a pair of cutting blades cutting an object by rotating about a rotation central axis; an electric motor for operating the cutting blades; and a guide plate having a recess in a manner of receding along a predetermined direction for housing the object in advance when cutting the object. An edge of the recess includes a pair of linear portions. When a position of the guide plate at a most front end along the predetermined direction is set as a first position, and a position in an operation range of each cutting blade at a most front end along the predetermined direction is set as a second position, a distance between the first position and the second position along the predetermined direction is one-fourth or less of the predetermined interval.

Abstract: An electric cutting device includes: a pair of cutting blades clamping and cutting an object; an electric motor generating a driving force for operating the cutting blades; a controller controlling the electric motor; and an operation device switched between an ON state and an OFF state by a user operation. After the operation device enters into the ON state and the pair of cutting blades start operating in a closing direction, the controller is configured to: open the pair of cutting blades when the cutting of the object is completed while the operation device is kept in the ON state; and stop closing the pair of cutting blades when the operation device changes from the ON state to the OFF state at a timing before the cutting of the object is completed.

Abstract: An electric cutting device includes: a pair of cutting blades having a first blade and a second blade, the pair of cutting blades being configured to clamp and cut an object; an electric motor configured to generate a driving force necessary for operating the cutting blades; a controller configured to control an operation of the electric motor; a first member provided with the first cutting blades; a second member provided with the second cutting blade; a restriction portion configured to come into contact with at least one of the first member and the second member to restrict an operable range of the pair of cutting blades; and a contact detector configured to detect that at least one of the first member and the second member comes into contact with the restriction portion.

Abstract: An electric tool includes a motor, an operation part provided to be operable by a user, a motor drive control unit configured to perform control of driving the motor in response to the operation part being operated, a temperature sensor, and a temperature determination unit configured to determine overheating of the motor. The temperature determination unit is configured to estimate a temperature of the motor based on a drive situation of the motor and a detection result of the temperature sensor, and to determine the overheating of the motor based on the estimated temperature.

Abstract: An electric tool includes an output part that comes into contact with a working target to process the working target, a motor that drives the output part, and a sensor that measures capacitance of a metal part comprising the output part. The electric tool detects a foreign object based on a change in the capacitance measured by the sensor.
