[0038] The connection mechanism further includes a limiting groove 302 provided on the inner side wall of the vertical hole, a connecting spring 303 fixedly connected to the inner side wall of the limiting groove 302, and a movable ring 304 fixedly connected to the end surface of the connecting spring 303;

[0039] The outer wall of the push-pull rod 301 is fixedly connected to the inner wall of the movable ring 304, wherein the outer diameter of the movable ring 304 is equal to the inner diameter of the limiting groove 302, and the central axis of the connecting spring 303 coincides with the central axis of the push-pull rod 301, wherein the connecting spring 303 is sleeved on the outer surface of the push-pull rod 301.

[0040] The connecting mechanism also includes an annular magnet 305 embedded in the inner wall of the vertical hole, the central axis of the annular magnet 305 coincides with the central axis of the push-pull rod 301, wherein the movable ring 304 is made of ferromagnetic material, and the movable ring 304 is adsorbed by the annular magnet 305, thereby compressing the connecting spring 303, and at this time, the top end of the push-pull rod 301 will be completely located inside the vertical hole.

[0041] When the dining chair is transported, the carrying plate 406 is moved to drive the permanent magnet 407 away from the seat surface 1, and then the end surface of the special-shaped rod 401 is conveniently pulled out of the locking groove 402 through the carrying plate 406, and then the special-shaped rod 401 is rotated and the end surface is inserted into the inside of the storage groove 409, so that the special-shaped rod 401 is fixed;

[0042] Then, the chair back 2 is rotated so that the engaging groove is directly opposite to the vertical hole, thereby making the chair back 2 perpendicular to the seat surface 1, and then the push-pull rod 301 is pushed to drive the movable ring 304 to move until the movable ring 304 is out of the adsorption range of the annular magnet 305, and the connecting spring 303 is restored to its original state, thereby driving the push-pull rod 301 to be inserted into the inside of the engaging groove, thereby fixing the chair back 2, and then rotating the bearing plate 406 to drive the support column 408 to move to the back of the chair back 2, so that the support column 408 can hang clothes, and its permanent magnet 407 can store objects made of magnetic materials such as keys;

[0043] During the movement of the chair back 2 , the push-pull rod 301 is retracted into the vertical hole under the action of the annular magnet 305 and the movable ring 304 , so as to prevent the push-pull rod 301 from interfering with the movement of the chair back 2 .
