DETAILED DESCRIPTION

[0019] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Reference Figure 1-3A labor-saving writing board includes a desktop 1, an extension rod 3 is provided on one side of the desktop 1, one end of the extension rod 3 is fixedly connected to a connecting frame 4, one side of the connecting frame 4 is fixedly connected to a rotating frame 5, a telescopic rod 6 is provided in the rotating frame 5, the telescopic end of the telescopic rod 6 is rotatably connected to the rotating frame 5, one end of the telescopic rod 6 is fixedly connected to a mounting frame 7, and an adjustment mechanism for adjusting the extension rod 3 is provided on one side of the desktop 1, the adjustment mechanism includes an adjusting nut 2 rotatably connected to one side of the desktop 1, and the extension rod 3 is threadedly connected to the adjusting nut 2.
