Abstract: A telescope sight collimating device including a laser aimer, a longitudinal center axle at one end of the aimer sleeved with a split sleeve and threadably engaged with a lock nut at its free end for positioning the device in the barrel of the gun, a tapered tubular locating rod and a tapered tubular tightening up rod respectively mounted around the longitudinal center axle and engaging both ends of the split sleeve, and an adjusting nut mounted around the longitudinal center axle and turned in either direction to move the tapered tubular tightening up rod forward or backward, causing the sleeve to be fixed to or released from the inside wall of the barrel of the gun.

Abstract: A laser pointer is disclosed including a laser module fitted into a conductive cylindrical casing and attached with a laser firing lens assembly and connected to a battery set and controlled by a switch to fire a laser beam for pointing, the laser module including a focus adjusting element threaded into the inner thread on the cylindrical shell thereof, whereby rotating the focus adjusting element on the cylindrical shell in either direction causes change of distance between the lens of the laser firing lens assembly and the laser diode of the laser module so that the focus is adjusted. The switch has a switching control press rod for switch control, and for fastening to the pocket as the laser pointer is not in use.

Abstract: A laser pointer is disclosed consisted of a laser module, a housing, a toggle switch, a push button, a constant power output control circuit, a ballpoint pen, a battery set, and a rotary cap, wherein the housing has chambers to hold the laser module, the battery set, and the push button ballpoint pen, and a clip for hanging; the toggle switch has a press rod controlled by a button to press a leaf spring on a PC board so as to electrically connect the battery set to the laser module in driving the laser module to emit a laser beam for pointing to things.

Abstract: A laser sight mounting device fastened to the trigger guard of a gun to hold a laser sight. The mounting device includes a mount having a gap defined between an arched block and a L-shaped frame thereof for receiving the trigger guard of a gun, a connecting plate fastened between the arched block and the L-shaped frame to retain the mount to the trigger guard, tightening up screw rods threaded into respective screw holes on the L-shaped frame against the trigger guard and tightened by respective locknuts to fix the mount in position, and a laser holder having a channel fastened to the L-shaped frame by screws and a hollow split cylinder controlled by an adjusting screw for mounting a laser sight.
