Therefore, by arranging the leveling component 3 on the unilateral extension table top, when the first table top 11 rotates relative to the second table top 12, the height of the first table top 11 relative to the second table top 12 can be adjusted through the rolling of the rolling piece 34 on the lifting track 33, so that the horizontal heights of the first table top 11 and the second table top 12 are kept consistent after the table top component 1 is unfolded, and the use comfort of the extension table is improved.

Further, a fixed seat 111 is disposed on a side of the first table top 11 facing the bearing member 31, the transmission assembly 2 is rotatably connected with the fixed seat 111, and the rotating member 32 is connected with the fixed seat 111; the fixing base 111 has an extension block 1111, the extension block 1111 extends away from the first table top 11, and the rolling member 34 is located at an end of the extension block 1111 away from the first table top 11 and is rotatably connected to the extension block 1111.

Therefore, the stability of the first tabletop 11 after being used can be improved, and the first tabletop 11 is ensured not to shake in the using process.

Further, the carrier 31 is also fixedly connected to the transmission assembly 2.

In this manner, stability of the second table top 12 is ensured, and stability of the table top assembly 1 during use is further improved.

When the novel tabletop is applied, a user rotates the first tabletop 11, the transmission piece 21 rotates along with the first tabletop 11, and the connection part of the transmission piece 21 and the first tabletop 11 moves relative to the second tabletop 12, so that the transmission piece 21 pushes or pulls the first tabletop 11 to be far away from or close to the second tabletop 12 under the pushing or pulling action of the transmission piece 21, the second tabletop 12 drives the first rail and the second rail to slide relatively, and the first tabletop 11 and the second tabletop 12 are gradually separated or contracted under the guiding action of the first rail and the second rail.

Further, the fixing base 111 is disposed near an end of the first table top 11.

In this embodiment, the first table top 11 is substantially square, and the fixing base 111 is disposed at one end of the first table top 11 in the length direction.

Therefore, after the tabletop assembly 1 is unfolded, the first tabletop 11 and the second tabletop 12 can be spliced, and the situation that a gap exists between the first tabletop 11 and the second tabletop 12 after the first tabletop 11 and the second tabletop 12 are unfolded to influence the comfort of a user is avoided.

Further, the lifting rail 33 is provided with a limit slot 333, and the limit slot 333 is located at the first end 331 and/or the second end 332.

Specifically, the limiting groove 333 limits the rolling element 34, in this embodiment, the limiting groove 333 is disposed at the first end 331, so that when the rolling element 34 rolls to the first end 331, that is, when the desktop assembly 1 is in the contracted state, the limiting groove 333 can limit the rolling element 34, that is, limit the first desktop 11, so as to avoid the first desktop 11 from rotating.
