Embodiment Construction
[0025] Please refer to FIG. 1 , which is a schematic structural diagram of the system of the present invention. The system structure includes: a driving motor 110 disposed on the mobile terminal 10 , a lens moving mechanism 120 , and a lens device 130 . When the mobile user uses the laser pointer, the key on the mobile terminal 10 activates the drive motor 110 to rotate, and then the drive motor 110 drives the lens moving mechanism 120 to work, and the lens device 130 for adjusting the laser pointer laser beam spot size is due to the lens moving mechanism 120 The driving effect of the laser beam starts to adjust the focal length of the laser beam, thereby adjusting the size of the laser beam spot.
[0026] The driving motor 110 may be a stepping motor.
[0027] Working mechanism of the present invention is as follows:
[0028] 1. When the mobile terminal phone is turned on, the software is initialized, and the stepping motor drives the lens moving mechanism to work to drive ...
