Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example 1, as shown in figures 1, 2, 3, 4 and 5, fig. 6 shows, a novel quick groove connector, including two connector body 6, 6 one end of connector body is equipped with first bolt head 4, the other end is equipped with second bolt head 5, be equipped with connecting device between connector body 6 and first bolt head 4 and the second bolt head 5 respectively, connecting device is including setting up external corner 1 and the reentrant corner 2 of setting at 6 opposite sides of connector body in connector body 6 one side, the external corner 1 at 6 both ends of connector body, reentrant corner 2 corresponds along the center pin of connector body 6 and sets up and external corner 1, the shape of reentrant corner 2 is corresponding, be equipped with supporting shoe 3 on the connector body 6 between external corner 1, the reentrant corner 2, the upper surface of supporting shoe 3 has an contained angle with the center pin of connector body 6, 3 opposite and two complementary contained angles of the supporting shoe of the slope direction of connector body 6 both ends.
