Abstract: A work tool includes an an elongate outer housing, an elongate inner housing, a motor, a spindle, and a transmitting mechanism. The inner housing includes a first end part, a second end part, an extending part and an elastic connection part. The motor, the spindle and the transmitting mechanism are disposed in the first end part of the inner housing. The first end part is connected to the outer housing via a first elastic member. The second end part includes a power-source-related device configured to enable power supply from a power source to the motor. The elastic connection part includes second elastic members connecting the extending part and the second end part. The second elastic members are spaced apart from each other in a circumferential direction around the longitudinal direction.

Abstract: A power tool enabled to detect an inadvertent rotation at higher accuracy includes a first sensor that detects a first driving information corresponding to a kinetic movement state of the tool body when the tool body is rotated around a longitudinal axis of the tool bit in the event of a working operation of the power tool, a second sensor that detects a second driving information corresponding to an output torque of the tool bit driven by the motor, and a controller connected to the first sensor and the second sensor for controlling the power tool. The controller is configured to calculate holding information corresponding to a holding force of a user to hold the tool body based on the first driving information and the second driving information and control the driving of the power tool based on the holding information.
