A handwriting device includes a supporting device using two supporting arms. Each of the supporting arms is an elongated plate, includes a sliding end and an opposite pivoting end, and further includes an engaging surface. The sliding ends of the supporting arms are slidably engaged in two respective sliding channels defined in a supporting base. A cutout is defined in the engaging surface at the pivoting ends. A through hole is defined at each of the pivoting ends where the cutout is formed. The through holes of the supporting arms are aligned with each other. The supporting arms are rotatably connected with each other via a threaded bolt passing through the through holes of the supporting arms. As such, the height of a camera module supported by the supporting arms can be adjusted. |
