The present invention relates to laser collimators, and particular to a laser collimator for calibrating collimation of laser beams of a golf bar, which emits laser light continuously without needing to press a switch continuously.
Currently, the laser beam from a laser collimator is a spot light, which is suitable for objects, such as laser beam or gun, for indicating a target. If the laser collimator is used in gun, not only the accuracy of the gun is increased greatly.
However, the prior art laser collimator is not effective as it is used in the golf bar, for example for the laser collimator used in a golf training field. In the prior art laser pen or laser collimator for calibrating the pose of a user, the button (for example, on an edge of a hat) for actuation a laser beam must be pressed continuously for emitting laser beam. However, the operation is inconvenient.

Thereby, the prior art has the following disadvantages.
The spot form the prior art laser collimator is spot light, which can not accurately indicate the object.
The switch must be pressed continuously. This will make the user feel ache and thus the work is affected. Especially as the laser collimator is used in a laser pen.
As the laser collimator is installed to a hat edge, the edge is buckled to a rod of the collimator so as to emit a laser beam. It is very possible that the switch is released due to the movement of the hat, and thus the laser collimator can not be work affectively.
Accordingly, the primary object of the present invention is to provide a laser collimator for calibrating collimation of laser beams of a golf bar wherein the laser collimator 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.
Another object of the present invention is to provide a laser collimator for calibrating collimation of laser beams of a golf bar, wherein a transparent sheet is installed in front of the laser light emitting body. One surface of the transparent sheet is 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.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
