A laser beam fired by a teaching laser pointer
Low-energy, monochromatic lasers are commonly used to indicate objects near or far, neon lights, signaling devices, etc. Laser pointer is a common carrier of low energy monochromatic laser. It involves a laser pointer. The problem of single shape of laser beam projected onto the screen by laser pointer is solved. On the basis of the existing green laser pointer, increased the light adjusting component, the laser adjustment component of bracket set in circular laser template, the template on the laser setup with N, the laser adjustment in the component ring set in the outer shell, its inner wall set limited slot and N positioning groove, shell wall and limit groove corresponding to the location of the set limited projections, The outer side wall of the shell is provided with a positioning protuberance corresponding to each positioning slot. In the actual use of this implementation, the position of the laser template is changed by rotating the adjustment ring, so that the laser beam passes through a pattern in the laser template, and then the laser beam is reshaped to form the corresponding pattern of the laser beam.

A laser pen comprises a pen case and a laser module, the laser module is arranged in the pen case, the front end of the laser module is provided with a first grating plate and a second grating plate, the first grating plate and the second grating plate are arranged in the light path center of the laser module, and the motor, the motor is connected with the first grating plate, driven by the motor rotation, The button on the surface of the pen shell is set to control the opening and closing of the high powered laser module and the motor. The technical solution adds the electric adjustment function to enhance the function of the laser pen, and the pattern change of the electric adjustment is continuous, and the change speed is uniform, which greatly increases the function and entertainment of the laser pen. The laser pointer still has the function of manual adjustment, users can actively choose electric adjustment or manual adjustment according to the need, the assembly of structural parts and structural parts can adopt interference fit or screw fit, very easy to assemble.
