[0035] See also Figures 1 to 9, a groove 218 is set on the side of the first table board 21, and a protrusion 228 is set on the side of the second table board 22. When the first table board 21 and the second table board 22 are in the same horizontal plane, the three ridges 2161 are just inserted into the three first engaging grooves 541 and engaged, and the protrusion 228 is inserted into the groove 218, so that the first table board 21 and the second table board 22 form a rectangular table board. In this state, the first table board 21 and the second table board 22 are used as a whole. When a certain weight is placed on the second table board 22, it will not be easily crushed or forced to rotate relative to the first table board 21; when the second table board 22 needs to be tilted, the user presses the button 217 or pulls the second table board 22 away from the first table board 21, and the shaft 32 compresses The spring 31 drives the second table board 22 away from the first table board 21 through the third step 52 and the fourth step 54. The three ridges 2161 are pulled out from the three first engaging grooves 541 and disengaged, and the protrusion 228 is pulled out from the groove 218. At this time, there is a certain distance between the second table board 22 and the first table board 21. The second table board 22 can be tilted upward or downward with the shaft 32 as the center. After tilting into place, release the button 217 or release the second table board 22, so that the three ridges 2161 are inserted into the second engaging grooves 542 to achieve engagement, so that the angle between the second table board 22 and the first table board 21 can be fixed at a certain angle, so that the user can place a mobile phone, tablet or book on the second table board 22 and support it on the first support plate 4 or the second support plate 224.
