Bosses 14 are provided on both sides of the unit combination plate 12 at the rightmost end of the folding baffle 4, and the bosses 14 extend into the corresponding connecting grooves opened on the inner side of the placement opening 10. In order to facilitate the retraction and hiding of the sewing machine table 2, the length of the threaded rod 7 matches the expected stroke of the sewing machine table 2 to be hidden in the storage box 3. Among them, the boss 14 provided on the unit combination plate 12 at the rightmost end of the folding baffle 4 is mainly used for the rotation of the folding baffle 4 as a whole to achieve the purpose of convenient folding and storage. The principle of the sewing machine in this device is an existing known technology, and there are mature products, so its principle will not be further explained.

[0023] In one embodiment, elbows are provided at the four corners of the bottom of the frame 1, and a roller 9 is rotatably installed on the inner side of each elbow. The elbows and rollers 9 are arranged to facilitate the movement of the frame 1.
