[0009] Through the above technical solution, the support frame is used to support the table top so that the table top can be parallel to the ground. Through the setting of multiple adjustment holes, the end of the support frame can be adjusted to adapt the angle of the table top. The structure is simple and easy to use.

[0010] In a preferred example, the present invention can be further configured as follows: a first sliding groove is provided in the table top, a sliding leg is provided at the connecting end between the support frame and the table top, and the sliding leg is slidably connected to the first sliding groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model utilizes the setting of two split expansion boards, which are respectively unfolded on both sides of the table board and fixedly supported by extension arms, thereby increasing the area of ​​the table board, so that more items can be placed on the table board, and larger items can also be placed, making this table board more convenient to use.

[0013] 2. The utility model utilizes a support frame to support the table top so that the table top can be parallel to the ground. Through the setting of multiple adjustment holes, the end of the support frame can be adjusted to adaptively adjust the angle of the table top. The structure is simple and easy to use.
