Abstract
The utility model relates to a novel dual-pose locking mechanism comprising pedestals, a driving element, connecting rods and a pin shaft. All connecting rods are connected by the pin shaft and, together with the pedestals, form a two-level four-rod mechanism; the dead point pose of the four rod mechanism at each level corresponds to the locking pose of the provided mechanism. The driving element serving as the unlocking device of the mechanism under the locking pose enables the mechanism to move from one locking pose to the other locking pose. When the mechanism is located at the locking pose, the external loading force or loading moment is eliminated completely by the rigidity of the mechanism itself, so that there is no need for the driving element of the unlocking device to carry any force or moment. On the basis of dimension parameter changing of all connecting rods, the locking pose of the mechanism can be adjusted. The provided mechanism has the self-locking function under two different poses and rapid unlocking can be realized by using the simple device; and the mechanism can be driven to carry out switching between two different locking poses.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of novel two pose locking mechanisms, comprises I level linkage, II level linkage and tripper, pedestal.
Described pedestal comprises the first pedestal 1 and the second pedestal 8;
As shown in Figure 2, I level linkage comprises take-off lever 2, intermediate bar 3, connecting rod 4, the first rotating shaft 9, the second rotating shaft 10, the first public rotating shaft 11, the second public rotating shaft 12, and connecting rod 4 is the first driving lever in I level linkage;
