ABSTRACT:
A laser pointer includes a first metal barrel having a first end closed with a metal screw cap, and a second end, which is opened, the first metal barrel holding a battery set, a control circuit board, an axially extended spring member and a laser diode supported on the axially extended spring member and extended out of the second end of the first metal barrel; a second metal barrel having a first end opened and coupled to the second end of the first metal barrel by a screw joint, and a second end opened, the second metal barrel being moved axially relative to the first metal barrel upon a rotary motion; and a socket mounted in the first end of the second metal barrel and moved with the second metal barrel axially between a first position where the socket is coupled to the laser diode to compress the axially extended spring member and hold the laser diode in position, and a second position where the socket is released from the laser diode, enabling the laser diode to be oscillated with the axially extended spring member when the laser pointer is oscillated by hand.
