When it is necessary to disengage the first connecting shaft 209 and the second connecting shaft 214, the first connecting shaft 209 is manually pushed, and the first connecting shaft 209 overcomes the elastic force of the second spring 211 and moves, thereby disengaging the short shaft 215 from the circular groove 216. When it is necessary to merge the first connecting shaft 209 and the second connecting shaft 214, the first connecting shaft 209 is manually pushed to move it. At this time, the short shaft 215 is aligned with the circular groove 216, and the first connecting shaft 229 is released. The first connecting shaft 209 moves under the action of the second spring 211 and engages the circular groove 216 with the short shaft 215.

[0047] Example 3

[0048] This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0049] Referring to 6, two fourth grooves 305 are provided on one side of the first table top 301, and the first clamping block 303 is rotatably connected inside the fourth groove 305, and the length of the first clamping block 303 is smaller than the length of the fourth groove 305. The first table top 301 is provided with a second clamping groove 307 on the outside of the two fourth grooves 305, and a fifth groove 306 is provided on one side of the second table top 302, and the second clamping block 308 is rotatably connected inside the fifth groove 306, and the length of the second clamping block 308 is smaller than the length of the fifth groove 306. When the second clamping block 308 is rotated to be perpendicular to the fifth groove 306, the second clamping block 308 corresponds to the position of the second clamping groove 307. The board 302 is located inside the two fifth grooves 306 and has a first card slot 304. When the first card block 303 is rotated to be perpendicular to the fourth groove 305, the first card block 303 corresponds to the position of the first card slot 304. When the first table board 301 and the second table board 302 need to be spliced, the two card blocks are placed in a vertical state by pulling the first card block 303 and the second card block 308, and the first table board 301 and the second table board 302 are merged and the first card block 303 is aligned with the first card slot 304, and the second card block 308 is aligned with the second card slot 307, so that the card blocks and the card slots are plugged into each other and then put together, thereby connecting the first table board 301 and the second table board 302.

[0050] Referring to 1, 7, and 6, a support leg 311 is movably connected to the top of the fixed rod 106, and a connecting block 309 is fixedly connected to the top of the support leg 311, and a connecting groove 310 is opened inside the connecting block 309, and the connecting groove 310 is a right triangle, and the height of the connecting groove 310 is adapted to the thickness of the first table board 301 and the second table board 302. A support rod 312 is fixedly connected to the bottom of both ends of the connecting block 309, and the end of the support rod 312 is fixedly connected to one side of the support leg 311, and the connecting groove 310 is aligned with the corner position of the table board and connected together by plugging. Since the connecting groove 310 is a right triangle, and the height of the connecting groove 310 is adapted to the thickness of the first table board 301 and the second table board 302, the connecting groove 310 is stably connected to the table board.

[0051] In this embodiment, when folding is required, the first buckle 104 is manually pulled to rotate the second fixing plate 103 upward, and then the third fixing plate 201 is pushed inward to rotate it inward. At this time, the two third fixing plates 201 in relatively positions rotate relative to each other and pull the positions of the first fixing plates 101 on both sides closer. When the third fixing plate 201 rotates to fit with the second fixing plate 103, the third fixing plates 201 at both ends also remain in a fit state, and the folding is completed. When it is necessary to open, the connecting rods 117 at both ends are pulled apart to separate the first fixing plates 101 at both ends until the two third fixing plates 201 in relatively positions are flush. At this time, the second fixing plate 103 is lowered, and the second fixing plate 103 rotates downward until it contacts the first protrusion 105 and stops, and the opening is completed.

[0052] When it is necessary to unfold it into a table and chair state, the first table board 301 and the second table board 302 are taken out from the top of the two first fixing plates 101, and the sides of the two table boards with the blocks installed are aligned, and the first block 303 and the second block 308 are pulled to make the two blocks in a vertical state, and the first table board 301 and the second table board 302 are combined and the first block 303 is aligned with the first slot 304, and the second block 308 is aligned with the second slot 307, so that the blocks and the slots are plugged into each other and then put together, thereby the first table board 301 and the second table board are assembled. 302 connection, remove the support leg 311 from the top of the fixing rod 106, align the connecting groove 310 with the corner position of the table board and connect them together by plugging, so as to complete the table top unfolding work, manually push the first connecting shaft 209, the first connecting shaft 209 overcomes the elastic force of the second spring 211 and moves, so that the short shaft 215 is separated from the circular groove 216, at this time the two relatively positioned third fixing plates 201 are separated from each other, step on the raised side of the support leg 208, manually pull the second buckle 207, at this time the second buckle 207 drives the rack 205 to The rack 205 slides backwards under the elastic force of the first spring 206, thereby staggering the rack 205 and the teeth 204, and the third fixing plate 201 is pulled to adjust it to a suitable height, and the second buckle 207 is released. At this time, the rack 205 is engaged with the teeth 204 under the action of the first spring 206, so that the slide plate 203 remains stationary, thereby completing the unfolding of the chair. When the table and chair state needs to be folded, the first table plate 301 and the second table plate 302 are pulled apart, the support leg 311 is manually taken out and inserted back into the top of the fixing rod 106, and the first block 30 3 and the second clamping block 308 are respectively moved to the inner sides of the fourth groove 305 and the fifth groove 306, and the first table top 301 and the second table top 302 are respectively inserted back on the top of the two first fixing plates 101. The two second fixing plates 101 of the two chairs are aligned. The first connecting shaft 209 is manually pushed to move it. At this time, the short shaft 215 is aligned with the circular groove 216. The first connecting shaft 229 is loosened. The first connecting shaft 209 moves under the action of the second spring 211 and engages the circular groove 216 with the short shaft 215, thereby transforming into a cart state.

[0053] When the height needs to be adjusted, the gear 109 is driven to rotate by rotating the knob 116, and the gear 109 drives the sleeve 114 to rotate through the transmission chain 110. Since the sleeve 114 is threadedly connected to the threaded rod 112, and the threaded rod 112 is fixedly connected to the support frame 107 through the fixed rod 106, the sleeve 114 is raised and lowered, and the sleeve 114 drives the first fixed plate 101 to move through the first connecting plate 111 to complete the height adjustment.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
