Abstract
An electric power tool includes: a housing; a motor that rotates about a first axis to generate a driving force; an output shaft connected to a working attachment, where the output shaft is drivable by the motor to drive the working attachment to rotate; a shaft locking mechanism operable to lock the output shaft when the motor is stopped; and a switch assembly operable to start the motor, where when the switch assembly is operated to start the motor, an operation acting on the switch assembly can release locking of the output shaft by the shaft locking mechanism.

An electric power tool, comprising:
- a housing;
- a motor that rotates about a first axis to generate a driving force;
- an output shaft connected to a working attachment, wherein the output shaft is drivable by the motor to drive the working attachment to rotate;
- a shaft locking mechanism operable to lock the output shaft when the motor is stopped;
- and
- a switch assembly operable to start the motor;
- wherein when the switch assembly is operated to start the motor, an operation acting on the switch assembly to start the motor releases locking of the output shaft by the shaft locking mechanism.
An electric power tool, comprising:
- a motor that rotates about a first axis to generate a driving force;
- an output shaft connected to a working attachment, and the output shaft is drivable by the motor to drive the working attachment to rotate;
- a shaft locking mechanism operable to lock the output shaft when the motor is stopped;
- and
- a switch assembly operable to start the motor;
- wherein the shaft locking mechanism is configured to unlock the output shaft in at least two ways.
An electric power tool, comprising:
- a motor that rotates about a first axis to generate a driving force;
- an output shaft connected to a working attachment, and the output shaft is drivable by the motor to drive the working attachment to rotate;
- a shaft locking mechanism operable to lock the output shaft when the motor is stopped;
- a switch assembly operable to start the motor;
- and
- a connecting member that connects the switch assembly and the shaft locking mechanism, wherein when the switch assembly is operated to start the motor, the connecting member drives the shaft locking mechanism to unlock the output shaft.
