ABSTRACT:
Disclosed is a folding knife with laser indicator mainly including two cases, a blade, and a laser indicating means. The laser indicating means includes a supporting plate pivotally connected to and between the two cases. A long recess is formed in the supporting plate to receive a springy conductive plate, a laser emitter, and a series of cells therein. The laser emitter has a laser diode and a focusing lens in it and has a spring provided to its inner end to contact with one pole of the cells. The conductive plate extends along an inner wall of the recess and has one end contacting with another pole of the cells and the other end extending to a point near an electrical contact of the laser emitter, such that a depression of a push button provided on an outer wall of the supporting plate shall press the conductive plate against the electrical contact of the laser emitter, electrically connecting the laser diode to emit light beam which passes through a hole formed at an outer end of the supporting plate.
