Further, a concave hole 603b is formed in the movable inner core 603, and a stress column 603c is fixed on the inner side of the concave hole 603b of the movable inner core 603; the first contact rod 706 is further provided with a through slot 707.

Further, a third elastic member 708 is further disposed between the leg 201 and the positioning seat 601.

In order to facilitate unlocking of the positioning seat 601 and the pre-installation seat 500, the length of the through groove 707 is larger than the length of the force bearing column 603c, the width of the through groove 707 is larger than the width of the force bearing column 603c and smaller than the length of the force bearing column 603c, the synchronization member 703 can be driven to rotate by rotating the outer ring 701, the synchronization member 703 can drive the first abutment rod 706 to rotate, the maximum angle that the synchronization member 703 can rotate is 90 degrees, when the synchronization member 703 is located at one end of the circular arc groove 201a, the force bearing column 603c and the through groove 707 are misplaced, the abutment head 601b-2 and the detachment groove 705 are misplaced, the force bearing column 603c cannot enter the inner side of the through groove 707, at this time, the first abutment rod 706 can push the movable inner core 603 through the force bearing column 603c, when the synchronization member 703 is located at the other end of the circular arc groove 201a, the force bearing column 603c is aligned with the through groove 707, the abutment head 601b-2 is aligned with the detachment groove 705, at this time the force bearing column 603c can enter the inner side of the through groove, and the legs 201 and the outer ring 701 can be separated from the limit of the elastic abutment member 601 b.

Therefore, when connecting the positioning seat 601 and the pre-installation seat 500, the force bearing column 603c and the through groove 707 are dislocated by rotating the synchronizing member 703, the first abutting column can push the movable inner core 603 through the force bearing column 603c, and after the connection state is reached, the first abutting column can keep the state of abutting the force bearing column 603c because the leg 201 and the positioning seat 601 are connected by the adjusting mechanism and cannot be separated, so that the unlocking problem caused by the detachment of the movable inner core 603 to the first direction is avoided.

When the unlocking is needed, only the outer ring 701 is required to be rotated, the outer ring 701 drives the inner disc 702 to rotate through the synchronizing member 703, so as to drive the first contact supporting rod 706 to rotate, when the synchronizing member 703 reaches the other end of the circular arc groove 201a, the stress column 603c is aligned with the through groove 707, the contact supporting head 601b-2 is aligned with the disengaging groove 705, the pressing force of the first contact supporting rod 706 on the stress column 603c disappears, the inner core 603 is moved to the first direction under the pushing of the first elastic piece 506, in the process, the rotating fastener 602 can be driven to rotate, and the rotating fastener is separated from the pre-installed seat 500 from the inlet port 504, so that the quick unlocking can be completed only by rotating the outer ring 701 when the unlocking is performed.

The stress column 603c and the pressing rod 202a-1 are opposite in cross section, and the cross section is uniform in size and shape.

After unlocking, the folding accommodating mechanism 200 needs to be folded, when the folding accommodating mechanism 200 is folded, the cross rod 202d is folded, in the folding process, the inner sliding member 202a moves towards the second direction, penetrates through the through groove 707 and is abutted against the stress column 603c, so that the stress column 603c is pressed to move towards the second direction, in the process, the end ring 602b separated from the inner side of the pre-installed seat 500 drives the hook 602c on the outer side of the pre-installed seat to rotate reversely, along with the folding of the cross rod 202d, the two legs 201 on the same side are close, the rotating hooks 602c on the two legs 201 are close to each other until buckling, and after the folding accommodating mechanism 200 is folded, the hooks 602c can position the legs 201 together, so that the problem that the folding accommodating mechanism 200 is unfolded by mistake is avoided.

When the folding containing mechanism 200 needs to be unfolded again, only the four movable inner cores 603 on the four legs 201 are required to face the ground and then pushed, the movable inner cores 603 are subjected to force in the first direction, and move in the first direction, the movable inner cores 603 drive the hooks 602c to rotate positively, and the two hooks 602c which are buckled are separated in a rotating mode, so that the folding containing mechanism 200 can be unfolded.

In order to enable the movable core 603 to be able to move in the first direction after being forced in the case where the two hooks 602c are buckled, the pressing rod 202a-1 is pressed against the movable core 603, a fourth elastic piece 202a-2 is provided between the pressing rod 202a-1 and the inner slide member 202a, and the fourth elastic piece 202a-2 is provided between the pressing rod 202a-1 and the inner slide member 202a, so that even in the case where the pressing rod 202a-1 keeps pressing against the movable core 603, the pressing rod 202a-1 can be pushed in the first direction to move a distance in the first direction to unlock the hooks 602 c.

The first elastic member 506, the second elastic member 601b-3, the third elastic member 708, and the fourth elastic member 202a-2 are all springs.

The rest of the structure is the same as in embodiment 2.
