Abstract

See full text

A lawnmower with operation protection and a safety switch mechanism. The safety switch mechanism include: an inner pipe and a pipe sleeve slidably connected with and enclosing the inner pipe, a safety switch with a contact tab mounted inside the pipe sleeve, a trigger configured to trigger the safety switch by contacting the contact tab when the inner pipe slides, and an elastomer configured to drive the trigger to keep from contacting with the contact tab. All of the safety switch, the trigger and the elastomer are arranged on the same side of the inner pipe. The safety switch mechanism functions to disable the motor upon accidental proximity of the operator to the cutter body to thereby lower the possibility of an accident.
