ABSTRACT:
An automatic output shaft locking mechanism for electric tools, and particularly a locking mechanism in which the output shaft is driven by electric power and will automatically lock in position when it is turned by an external force, including a retaining end with three equi-angular projections at one end of the output shaft in the tool, and a rotary disk having three equi-angular notches at an outer side. The outer portion of the rotary disk is fitted with a securing ring, and its three notches receive lock rollers respectively. When the retaining end turns, the three projections will push the lock rollers to engage the securing ring so that the output shaft is locked in position.
