The trigger lever with a pivoting point is capable of pivoting around the pivoting point, and the distance from a first contact point of the safety switch and the trigger lever to the pivoting point is longer than that from a second contact point of the trigger switch and the trigger lever to the pivoting point. The safety switch system is sensitive in trigger and labor-saving in operation.
