Abstract: A laser collimator for calibrating collimation of laser beams of a golf bar comprises a discharge circuit including a capacitor and a resistor for controlling the discharging time; a switch; a digital circuit for generating preset and clearing actions so as to control the conduction and disconnection of current; the digital circuit being controlled by the switch; a boot type driving circuit for driving a following element; and a laser light emitter driven by the boot type driving circuit so as to illuminate; a transparent sheet being installed in front of the laser light emitting body; one surface of the transparent sheet being installed with a plurality of strips so that the laser beam from the laser light emitting body being as a straight beam. In using, as the switch is actuated, the laser light emitting body emits a straight beam for guiding a path of the golf ball so as to calibrate the pose of the user.

Abstract: A mount for attaching a laser aiming device to a golf putter comprises a laser bracket for housing a laser aiming device and a golf-club holder. The laser bracket is provided with a sliding recess on a lateral side thereof, being tapered off upwardly. The golf-club holder has a flat portion for being embedded into the sliding recess on the laser bracket and a circular portion for holding a golf club. Thereby, the laser bracket can be fastened together with the golf-club holder as the flat portion is inserted along the sliding recess. At least one non-slip rubber pad is disposed on the inner wall of the circular portion of the golf-club holder, and a retaining screw is installed on the outer side of the circular portion of the golf-club holder. The rubber pad and the retaining screw further enhance the golf-club holder's grip on a golf putter.

Abstract: A circuit device dedicated in a remote control switch comprises the following elements. A voltage conversion circuit serves for converting AC input current to DC current. A photo sensor serves for sensing a laser light and receiving the DC current from the voltage conversion circuit. A switch button generates a trigger signal as the photo sensor senses an input laser light. A signal integrated circuit is turned on as the signal integrated circuit receives the trigger signal from the switch button. A flip-flop is capable of changing state as the signal integrated circuit is turned on. A relay serves for changing the operation state when the relay receives an input signal from the signal integrated circuit, thereby, the electric device connected to the flip-flop can be switched on or off when the flip-flop changes state.

Abstract: The present invention relates to an improve structure of the aiming device of a golf putter, more particularly to an improved structure of “golf putter” as disclosed in the R.O.C. Patent Publication No. 388,289 that requires less mechanical components and has simple shape and easy-to-design mold for mass production to effectively lower the manufacturing cost of the laser aiming device of the club head of a golf putter. It primarily comprises a base with a laser emitting module being coupled by a buried head screw to a bottom chassis or two bottom chassis, wherein the laser emitting module further comprising a press button being coupled to a laser emitter and a conductive plate, which are disposed in two different sized holes and a battery accommodation cavity on the same surface of the base.
