The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.It should be noted that at this, be used for helping to understand the utility model for the explanation of these embodiments, but do not form restriction of the present utility model.In addition,, in each embodiment of described the utility model, involved technical characterictic just can interosculate as long as do not form each other conflict.

In the utility model is described, term " on " and orientation or the position relationship of the indication such as D score be based on orientation shown in the drawings or position relationship, it is only the utility model rather than require the utility model with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model for convenience of description.

In description of the present utility model, term " first " and " second " be only for describing object, and can not be interpreted as indication or hint relative importance.

As shown in Figure 1 to 9, it is a kind of folding joint device, comprise upper cover 1 and the lower cover 4 of hinged setting, described upper cover is provided with the support 11 of axis hole 111, described lower cover arranges mount pad 41, described support 11 is corresponding with the position of described mount pad 41, described mount pad arranges bolt 6, described support is provided with rotating latch hook framework 2, described latch hook framework is provided with the breach 24 being interlocked with described bolt 6, the rotating rotating shaft 9 in both ends is set in described axis hole 111, an end in described rotating shaft is provided with eccentric wheel 91, the outer sheathed retracing spring 8 of described rotating shaft,

On the two side of described latch hook framework 2, have the first mounting hole 21 and the second mounting hole 22, be provided with the linked block 23 of outwardly convex in a sidewall of described latch hook framework or end, two side, described eccentric wheel 91 is arranged in the first mounting hole 21 rotatable, and the other end of described rotating shaft 9 is arranged in the second mounting hole 22 rotatable;
