About the manufacturing principle of the page turning laser pointer
Laser pointers are widely used in conferences and classroom teaching presentations. Currently, the page turning buttons of the commonly used laser pen are separated. For example, at least three buttons are provided on the pen body, namely, a page-up button, a page-down button, and a laser button. The operator needs to look down at the position of the laser pointer button in his hand each time before performing corresponding control. Because the controller will adjust the position of the hand autonomously at any time during a long lecture on a certain page to avoid local stiffness, so when you want to manipulate the laser pointer buttons, you need to look at the buttons before you can find the corresponding buttons.
