Abstract
A handsaw (1) includes a handle (11), a blade (13) mounted on the handle (11), and a light emitting member (121) mounted on the handle (11) to produce a longitudinal light source (123) aligning with a lower edge (131) of the blade (13). Thus, the sawing line (21 ) of the workpiece (2) and the longitudinal light source (123) of the light emitting member (121) are directed in the same direction, so that a worker can drive the blade (13) to move in the common direction indicated by the sawing line (21) of the workpiece (2) and the longitudinal light source (123) of the light emitting member (121) to cut the workpiece exactly, thereby facilitating the worker sawing the workpiece, and thereby greatly enhancing precision of sawing the workpiece.
Description
HANDSAW HAVING SAWING GUIDE FUNCTION
The present invention relates to a handsaw, and more particularly to a handsaw having a sawing guide function.
A conventional handsaw comprises a handle, and a blade mounted on the handle. In practice, a worker can drive the blade to move in the direction indicated by a sawing line drawn on a workpiece so as to cut the workpiece according to the sawing line of the workpiece. However, the blade is easily vibrated or inclined during the sawing process due to an unevenly distributed force applied by the worker, so that the blade is easily deflected from the sawing line of the worlcpiece, thereby greatly decreasing precision of sawing the workpiece.
The primary objective of the present invention is to provide a handsaw having a sawing guide function.
Another objective of the present invention is to provide a handsaw, wherein the sawing line of the workpiece and the longitudinal light source of the light emitting member are directed in the same direction, so that a worker can drive the blade to move in the common direction indicated by the sawing line of the workpiece and the longitudinal light source of the light emitting member so as to cut the workpiece exactly, thereby facilitating the worker sawing the worlcpiece, and thereby greatly enhancing precision of sawing the workpiece.
