A positioner of a chair adjusting device is disclosed. The positioner is formed by stacking a plurality of positioning plates together. Each of the positioning plates is formed with a positioning section, a combination section, and a penetration section. The combination section is formed of a recessed cavity recessed from one surface and a projecting peg projecting from an opposite surface, and an outside diameter of the projecting peg corresponds to an inside diameter of the recessed cavity, so that for two of the positioning plates that are stacked together to be respectively on an upper side and a lower side, the projecting peg of the positioning plate on the upper side is receivable into and fit in the recessed cavity of the positioning plate on the lower side to have the two positioning plates that are stacked together on the upper and lower sides combined together through tight fitting.

A dining chair includes: a pair of support legs having inner surfaces, the inner surfaces defining a pair of slide grooves, each of the slide grooves extending along a direction that is parallel to a surface; a seat having a front end, a rear end, and two opposite sides between the front end and the rear end, one of the sides including a first side, a second side, and a shoulder formed between the first and second sides, the first side slidably received in one of the slide grooves, and the shoulder abutting against a closed end of the one of the slide grooves; and a locking mechanism fixed to the seat adjacent to the one of the sides of the seat, the locking mechanism including a locking member that is to move past the second side and abut against a rear end face of one of the support legs.

The present invention discloses a foldable swing, including support frames and a swing seat, where the swing seat is connected to the support frames by hangers, the support frame includes a first support rod, a second support rod and a connecting rod, the two support rods are arranged one in front of the other in a cross-hinged manner, the connecting rod is located between the two support rods, and both ends of the connecting rod are respectively movably connected to the two support rods. The present invention can achieve folding or unfolding of the foldable swing.

A telescopic folding chair includes an upper mounting seat, a lower mounting seat and a cushion. The upper mounting seat is hinged with a plurality of support legs, and the lower mounting seat is hinged with a plurality of telescopic arm tube sets. The cushion is mounted on the telescopic arm tube sets. The lower mounting seat is provided with a plurality of inclined guide holes through which the support legs run. The upper mounting seat is rotatably provided with a rotary limiting mechanism, and the lower mounting seat is provided with an avoidance hole. A bottom of the rotary limiting mechanism is provided with a limiting head, and a bottom wall of the lower mounting seat is provided with a limiting portion corresponding to a periphery of the avoidance hole. The rotary limiting mechanism rotates to control the limiting head to be movably limited by the limiting portion.
