Handheld cutting tool

The invention discloses a handheld cutting tool, which comprises a machine body, a motor contained in the machine body, a cutting element, and a support element, wherein the cutting element is driven by the motor for cutting a work-piece and has a cutting direction; the support element is used for supporting the machine body and has a resisting surface which resists against the work-piece; a locating ruler is arranged on the support element; a scale extension direction of the locating ruler is parallel to the cutting direction; a stopper is also arranged on the locating ruler, and the stopper comprises a baffle surface which protrudes out of the resisting surface and is vertical to the resisting surface. A user just determines the length to be cut through the locating ruler, and the stopper immediately contacts the work-piece to prevent the cutting tool from further advancing when the cut length is just the fixed length. Compared with a fixed length cutting mode of drawing a fixed length line segment on the work-piece, the method disclosed by the invention is more convenient, the cutting precision is higher, and the work efficiency is improved.
