ABSTRACT:
A securing mechanism for securing a drive shaft of a rotating tool member of a working tool against rotation includes a securing member fixedly connected to the drive shaft. The securing member has at least one engagement opening. A lock bolt for engaging the at least one engagement opening is provided. The lock bolt is axially displaceably positioned in the housing of the working tool. A spring for biasing the lock bolt into engagement with the at least one engagement opening is provided. An actuating element for displacing the lock bolt from an engaged position, in which the lock bolt engages the at least one engagement opening, into a disengaged position, in which the lock bolt is removed from the engagement opening, is provided. The actuator element is positioned adjacent to the lock bolt and has a cam member extending into the travel path of the lock bolt. The cam member has a securing position in which the cam member is locked at the housing for securing the lock bolt against the force of the spring in the disengaged position.
