One end is equipped with two secondary resilient stays, has fixinig plate and spring steel plate, the spring steel plate of two secondary resilient stays per pair resilient stay
Relatively, the tail end of two secondary resilient stays is connected on the both side plate of first section bar respectively by two screws, first section bar
Two secondary resilient stay heads are inserted into two link slots of second section bar and connect two section bars respectively, are furnished with per pair resilient stay
Locking member, locking member have cam, camshaft and handle, and camshaft is supported by fixinig plate, and handle is stretched from the window of fixinig plate
Go out, lock the connection of two section bars when cam promotes spring steel plate to be close on corresponding side plate.
Fixinig plate per resilient stay is equipped with arc axis hole with respect to the face of spring steel plate, and camshaft is placed in arc axis hole
In.
The locking member is integrated through injection molding part.
The utility model has following good effect：The utility model is inserted into respectively by two secondary resilient stays of corner pieces
Be connected in two link slots of section bar with section bar or a section bar on two secondary resilient stays be inserted into two connections of another section bar respectively
It is connected in slot with another section bar.The utility model locks the connection of corner pieces and section bar by locking member, passes through locking pair
The connection locking of two section bars.Locking member is cam structure, is rotated by handle band moving cam, when cam is tight against spring steel plate, spring
Steel disc deformation is close on corresponding side plate and realizes connection locking, thus it is simple in structure, it is easy to connect reliable, and process also side
Just.
