ELECTRIC TOOL
Document Type and Number:
WIPO Patent Application WO/2022/181041
Kind Code:
A1
Abstract:
The objective of the present disclosure is to improve the accuracy of control of an electric tool according to torque. An electric tool (1) is provided with a holding unit (11), a motor (15), a transmission mechanism (3), a torque detection unit, a clutch mechanism (C1), and a control unit. The holding unit (11) is configured to hold a tip tool (12). The transmission mechanism (3) transmits torque of the motor (15) to the holding unit (11). The torque detection unit detects the torque transmitted from the motor (15) to the holding unit (11). The clutch mechanism (C1) is switchable between a transmission state in which the torque of the motor (15) is transmitted to the holding unit (11), and a disengaged state in which the torque of the motor (15) is not transmitted to the holding unit (11). The control unit switches the clutch mechanism (C1) from the transmission state to the disengaged state when a predetermined condition related to the torque detected by the torque detection unit is satisfied.
