Folding knife with laser indicator

A folding knife with laser indicator, comprising an upper and a lower cases, a blade pivotally connected to and between said cases, and a laser indicating means pivotally connected to and between said two cases;

• said lower case being formed on an inner surface with an inclined brake plate, said upper case being formed at one side with a dent to expose a small part of said brake plate so that said brake plate may be depressed with a finger via said dent;
• said blade being allowed to be pivotally turned into and between said two cases or be pivotally turned out of said cases with said brake plate abutting a distal edge against a rear edge of said extended blade to prevent said blade from moving at the extended position;
• and
• said laser indicating means further comprising a supporting plate pivotally connected to and between said two cases and formed with a long recess, a laser emitter disposed in said long recess of said supporting plate and having a laser diode, a controlling circuit, and a focusing lens mounted therein, a series of cells disposed in said long recess opposite to said laser emitter, a spring provided to an inner end of said laser emitter to contact with said series of cells, and a springy conductive plate disposed in said long recess along an inner wall thereof with a bent end contacting with said cells and an extension part extending to a point near a conductive contact of said laser emitter;
• said supporting plate being provided at an outer side with a push button slightly projected from an outer periphery of said supporting plate, and depression of said push button allowing said push button to press said extension part of said springy conductive plate against said contact on said laser emitter and thereby electrically connects said laser diode in said laser emitter for said laser emitter to emit light spot from a through hole provided to an outer end of said supporting plate.
