One end of the connecting rod 4 is hinged to the connecting sleeve 3, and the other end is hinged to the bottom end of the chair leg, and at least two chair legs and the connecting sleeve 3 are respectively provided with a positioning assembly for fixing the position of the connecting sleeve 3.

[0026] The four chair legs in the embodiment include two adjacent front chair legs 1 and two adjacent rear chair legs 2, the front chair legs 1 are the two chair legs in the front part of the picnic chair, and the rear chair legs 2 are the two chair legs in the rear part of the picnic chair, and the two rear chair legs 2 and the connecting sleeve 3 are respectively provided with a positioning assembly.

[0027] The positioning assembly comprises a spring positioning bead 5 arranged on the rear chair leg 2, the round tube of the spring positioning bead 5 is fixed in the chair leg, the steel ball thereof is out of the peripheral wall of the chair leg, a positioning hole 6 is formed in the connecting sleeve 3, when the connecting sleeve 3 slides to align with the positioning hole 6 and the spring positioning bead 5, the spring positioning bead 5 will be inserted into the positioning hole 6, so as to fix the position of the connecting sleeve 3. The positioning hole 6 penetrates through the peripheral wall of the connecting sleeve 3, when the picnic chair needs to be folded, the user presses the spring positioning bead 5 inward, so that the spring positioning bead 5 is separated from the positioning hole 6, the connecting sleeve 3 can slide again, and the picnic chair can be folded.

[0028] The connecting rod 4 is connected between the connecting sleeve 3 on the rear chair leg 2 and the front chair leg 1, and the front chair leg 1 cannot be retracted inwardly by fixing the connecting sleeve 3 on the rear chair leg 2, so that the positioning assembly is not arranged on each chair leg, and the positioning assembly arranged on the two rear chair legs 2 can be directly operated by the user's hands. The front chair leg 1 is not provided with a positioning assembly, and the connecting sleeve 3 on the front chair leg 1 is shorter than the connecting sleeve 3 on the rear chair leg 2.

[0029] The positioning hole 6 is arranged on the side of the connecting sleeve 3 away from the front chair leg 1, that is, on the back side of the picnic chair, and penetrates through the peripheral side wall of the connecting sleeve 3.
