Jigsaw cutting direction positioning system, has luminescence device that is positioned above jigsaw on fixing seat such that plane of light beam emitted from device coincides exactly with plane of blade mounted on saw

摘要

The system has a luminescence device (3) that emits light beam and is connected to a power supply through a wire (4). The luminescence device is positioned above a jigsaw on a fixing seat (2) such that plane (of light beam emitted from the device coincides exactly with the plane of a saw blade (6) mounted on the jigsaw for cutting wood. The seat is placed on an upper case (1) of the jigsaw.
