[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-3 and Figure 5 Existing folding chairs are inconvenient to carry when used outdoors. To solve this technical problem, this embodiment discloses the following technical content;

[0027] The left and right ends of the short support 2 are set inside the long support 1, and the middle of the long support 1 and the short support 2 are rotatably connected by the connecting rod 3. The left and right ends of the bottom of the long support 1 and the short support 2 are both connected with the support pad 4. The middle of the inner side of the long support 1 is fixedly connected with the crossbar 5. The top of the short support 2 and the outer side of the crossbar 5 are connected to the two ends of the seat cushion 6. The outer side of the top of the crossbar 5 and the top of the long support 1 are connected to the two ends of the back cushion 7. The seat cushion 6 and the back cushion 7 are an integral structure.

[0028] The seat cushion 6 and back cushion 7 are an integrated structure. The seat cushion 6 and back cushion 7 are made of soft material. The long support 1 and short support 2 can be rotated through the connecting rod 3. The long support 1 and short support 2 can be closed together. The folding chair has a simple structure and is portable.

[0029] Example 2: Existing folding chairs are inconvenient to secure when folded to prevent them from opening automatically, and when in use, it is inconvenient for the user to adjust or remove the headrest while leaning against the backrest. Therefore, this example uses the following technical solution, such as... Figures 1-4 As shown;

[0030] A connecting ball 8 is fixedly connected to the middle of the left side of the long bracket 1, and the connecting ball 8 is connected through the connecting holes 10 opened at the middle of both ends of the leather rope 9.

[0031] After the long bracket 1 and the short bracket 2 are closed together, wrap the outer end of the leather rope 9 around the left side of the long bracket 1 and the short bracket 2, and then connect the connecting hole 10 at the outer end of the leather rope 9 to the connecting ball 8. This can fix the long bracket 1 and the short bracket 2 in place and prevent the long bracket 1 and the short bracket 2 from unfolding automatically.

[0032] The headrest mechanism is composed of a connecting ring 11, a stabilizing bolt 12, a long frame 13, and a headrest body 14. The lower surface of the long frame 13 is fixedly connected to the left and right ends of the stabilizing bolt 12. The middle rear side of the connecting ring 11 is threaded with the stabilizing bolt 12, and the upper end of the inner side of the connecting ring 11 is in contact with the outer side of the top of the long frame 1. The front side of the stabilizing bolt 12 is connected through to the rear side of the top of the long frame 1. The middle upper surface of the long frame 13 is fixedly connected to the headrest body 14.

[0033] When using the folding chair, a headrest mechanism can be installed at the top of the long support 1. After placing the connecting ring 11 at the top of the long support 1 and adjusting the angle of the headrest, the connecting ring 11 is fixed to the top of the long support 1 with the stabilizing bolt 12, so that the user can rest their head on the headrest body 14.
