Inventor: Xiongfei Zhao.
This utility model discloses a projection device that can change the length of the laser pattern based on the distance from the surface being measured. It includes a shell, a range measurement module, a laser marking module, an adjustment button, and a control circuit board.
The shell has a first light exit for the laser to exit and a second light exit. The range measurement module is used to detect the distance between the first light exit of the projection device and the measured position, and outputs the detected distance signal. The laser emitted by the laser marking module exits from the second light exit and is projected on the measured position.
The adjustment button is used to adjust the length of the laser pattern emitted by the laser marking module. This utility model can adjust the length of the laser pattern in the projected area on the projection plane according to the distance of the measured surface.
