When the slide bar 46 is inserted into the card slot 47, the first spring 48 is in a stretched state, so the rebound elastic force of the first spring 48 acts on the slide bar 46 to strengthen the connection effect between the slide bar 46 and the card slot 47. When the limit block 45 is retracted into the clearance groove 43, the second spring 49 is in a twisted state. Therefore, in the process of sliding the rectangular block 42 to the limit groove 410, when the clearance groove 43 enters the limit groove 410, the second spring 49 is in a twisted state. After the sofa cushion 3 is placed, the two limiting blocks 45 rotate and unfold under the action of the rebound elastic force of the second spring 49, making the connection operation more convenient. When the sofa cushion 3 is placed, the four round rods 52 can be respectively inserted into the corresponding round grooves 51 to limit the sofa cushion 3 and prevent the sofa cushion 3 from slipping during use. The first magnetic block 53 and the second magnetic block 54 are in contact and are tightly attracted together under the action of magnetic force, which can enhance the limiting effect. The magic mother sticker 56 and the magic child sticker 55 are pasted together to further enhance the limiting effect.
