Abstract:
A laser pointer comprising:a bottom cover shell shaped like a flat box;a top cover shell covered on said bottom cover shell, said top cover shell having a laser firing hole;battery means mounted inside said bottom cover shell, said battery means having a negative terminal at a bottom side thereof and a positive terminal at a top side thereof;a laser module mounted in said bottom cover shell and controlled to emit a laser beam out of the laser firing hole at said top cover shell, said laser module comprising a laser diode and lens unit, and a circuit board connected to said laser diode and lens unit and controlled to drive said laser diode and lens unit, said circuit board having a positive terminal and a negative terminal;a first metal contact plate fixedly mounted in said bottom cover shell, said first metal contact plate having a lead end connected to the negative terminal of said circuit board and a tail end disposed in contact with the negative terminal of said battery means;a second metal contact plate fixedly mounted in said bottom cover shell, said second metal contact plate having a lead end connected to the positive terminal of said battery means and a tail end; anda third metal contact plate fixedly fastened to said top cover shell, said third metal contact plate having a lead end suspended above the tail end of said second metal contact plate, and a tail end disposed in contact with the positive terminal of said battery means;wherein when the lead end of said third metal contact plate is forced downwards into contact with the tail end of said second metal contact plate, said circuit board is triggered to drive said laser diode and lens unit, causing said laser diode and lens unit to emit a laser beam out of the laser firing hole at said top cover shell.
