1. An electric circular saw, comprising
a housing; a switch trigger arranged on the housing; a switch controlling rod for limiting the travel range of the switch trigger, wherein the switch controlling rod is pivotally mounted to the inner wall of the housing through a pin shaft, a stopping member for limiting the travel range of the switch trigger is arranged between the switch controlling rod and the switch trigger, and the rotation of the switch controlling rod forces the stopping member to get out of the travel range of the switch trigger so as to control the operation of the switch trigger, the switch controlling rod further comprises an elastic member for causing the switch controlling rod to force the stopping member to restore towards the switch trigger, and the switch controlling rod is more connected with a pushing button protruding out from the housing in a normal state; a base plate; a depth support arranged on the base plate; a first connecting rod for limiting the travel range of the depth support; a rotary plate arranged in the housing, the rotary plate comprising a first convex portion protruding outwards from a side of the rotary plate for driving the first connecting rod, and a second convex portion protruding outwards from the side of the rotary plate in the front of the first convex portion in a first direction for limiting the switch controlling rod, and the moving distance between the first convex portion and the first connecting rod being larger than or equal to that between the second portion and the switch controlling rod.
