Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Fig. 1 to 5, a kind of folding bracket of the present utility model, comprise the first travel(l)ing rest 1 and the second travel(l)ing rest 2 that position-limited lever 6, intersection are flexibly connected, the top of two travel(l)ing rests is equipped with chassis 3, the first travel(l)ing rest 1 both sides, top are respectively equipped with slide rail 4, the cross section of described slide rail 4 is inverted U, and the inner side surface of slide rail 4 and outer side surface are provided with symmetrical barb type sliding-rail groove, and sliding-rail groove comprises slide rail top 17, slide rail afterbody 16 and slide rail end 18; Described position-limited lever 6 one ends are connected with spacing angle bar 5, after position-limited lever 6 the other ends insert springs 11 and pass chassis 3, with first, handle knob and 7 are connected; Be provided with screw 20 in sliding-rail groove.

In the present embodiment, position-limited lever 6 is connected with an end of spacing angle bar 5 by lock screw 10 and, to spacing angle bar 5 lockings, spacing angle bar 5 also is connected and take connecting pin 9 as the axle rotation with the connecting pin 9 in insertion slide rail 4.Screw 20 comprises head, axial region and screw section, and screw section is riveted on the first travel(l)ing rest 1, and axial region is stuck in sliding-rail groove, the sliding-rail groove of head exposing inside thereof face.The second travel(l)ing rest 2 is provided with limiting board 13, and position-limited lever 6 is provided with the position limit pin 14 suitable with limiting board 13.Spacing angle bar 5 be shaped as circular arc.Four drift angle places on chassis 3 are provided with respectively beam 15, and 3 sides, chassis are provided with handle 12.

The utility model is in working order the time, screw 20 is in slide rail top 17, for preventing that screw 20 from skidding off from slide rail top 17, the spacing angle bar 5 of being furnished with herein arcuation, in any case to guarantee to move back and forth chassis 3, screw 20 can not slide into slide rail afterbody 16 from slide rail top 17, and now second handles knob 8 in locking state.
