DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] Embodiment: A marker for making tables, such as Figure 1-Figure 4As shown, the whiteboard 1 includes a whiteboard 1 and legs 12 on both sides, the whiteboard 1 and the legs 12 are rotatably connected to each other, a marker 2 is arranged on the front of the whiteboard 1, the marker 2 includes a U-shaped frame 21 and a special-shaped square tube 26, a pad 25 is arranged between the special-shaped square tube 26 and the U-shaped frame 21, and the special-shaped square tube 26 and the U-shaped frame 21 are connected to each other at the connection point by bolts, the U-shaped frame 21 is slidably arranged on the top of the whiteboard 1, the special-shaped square tube 26 is installed on the front of the U-shaped frame 21 by bolts, and the special-shaped square tube 26 is located at the front of the whiteboard 1 and extends downward, a first connecting member 210 is arranged on the front of the special-shaped square tube 26, a second connecting member 211 is arranged on one side of the first connecting member 210, the first connecting member 210 and the second connecting member 211 are connected by bolts, a pen cover 214 is inserted in the second connecting member 211, a threaded groove is arranged on the front surface of the pen cover 214, and the pen cover 214 is threadedly connected to a threaded sleeve 212 through the threaded groove.
