Abstract
A false triggering prevention device for a spindle self-locking mechanism of an electric tool, includes a blocking member and an elastic element, where the blocking member includes a rotating portion, a connecting portion and a blocking portion that are sequentially connected to one another; one end of the elastic element is connected to a gear; the other end of the elastic element is connected to the connecting portion; the rotating portion is rotatably connected to a self-locking surface of the gear, such that the blocking member has a rotating state and a static state; when the blocking member is in the rotating state, the blocking portion covers a self-locking hole to prevent insertion of the self-locking pin into the self-locking hole; and when the blocking member is in the static state, the blocking portion does not cover the self-locking hole.
