[0076] When the user has finished using the placement frame 29, the user can directly rotate the rotating rod 35 so that the placement frame 29 can enter the placement box 6, and then the user rotates the first baffle 25 to further place the first baffle 25 above the placement frame 29, so that the placement frame 29 can be limited.

[0077] The user can directly select different surfaces of the third table top 42 according to the temperature at that time, and then place the third table top 42 in the placement cavity 38, and then rotate the second baffle 27, so that the third table top 42 can be limited. When the user uses the hot surface, the external control switch can be turned on directly, and the semiconductor refrigeration plate 424 can be further operated, so that the third table top 42 can be heated up. At the same time, it is particularly noted that the first table top 7 is made of insulating material, thereby ensuring the safety of the user.

[0078] A puzzle board 82 is provided below the second desktop 81, and the puzzle board 82 is fixed to the second desktop 81 by a plurality of fixing screws 83. The puzzle board 82 can be a desktop for various puzzle games, or a Lego model base, further increasing the practicability of the device.
