Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment one：
As depicted in figs. 1 and 2, the supporting construction between two folding rods in the present embodiment includes the first folding rod 1, second
Folding rod 2, first support bar 3 and second support bar 4, the first folding rod 1 are mutually rotated with the second folding rod 2 and are connected, first
The rear end of strut 3 is articulated with the first folding rod 1, and the rear end of second support bar 4 is articulated with the second folding rod 2, the first support
The front end of bar 3 is located to be hinged with the leading head of second support bar 4 rearward, the leading head of first support bar 3 and second
Place is provided with locking structure rearward for the front end of strut 4.It is mutually locked under state in first support bar 3 and second support bar 4, the first folding
Folded bar 1, the second folding rod 2, first support bar 3 and second support bar 4 collectively form the triangular support configurations of stabilized structure, first
Folding rod 1, the second folding rod 2, first support bar 3 and second support bar 4 can not be rotated mutually.
In the present embodiment, the front end of first support bar 3 forms U-type groove 5, and the first bearing pin is fixed with the afterbody of U-type groove 5
