Because the buckle 30 is hinged on the first clamping plate 10, the free end part of the buckle can be conveniently clamped on the clamping bolt 40 around the clamping bolt 40; simultaneously, buckle 30 free end tip tangential direction A and the relation between the thread clamping board separation tangential direction B for buckle 30 is difficult for the unblock after the joint is to joint bolt 40, and the joint is firm. As shown in fig. 10, the free end of the buckle 30 is designed to exceed the center line 308, and an inward convex angle is formed at the end to form an angle component opposite to the separation direction of the two clamps 10 and 20, so as to prevent the buckle 30 from being separated from the clamping bolt 40. And because the buckle 30 moves along the side surface of the clamping bolt 40, the arm of force of the user acting on the contact point 3-4 between the buckle 30 and the clamping bolt 40 is longer than the arm of force of the clamping bolt 40 acting on the contact point 3-4, therefore, the clamping is more labor-saving and more convenient.

As shown in fig. 2 and 8, the clip 30 is in the shape of a tab, and the radius of the arc of the tab 30 for engaging with the latch bolt 40 corresponds to the distance from the hinge of the clip 30 to the latch bolt 40 in the engaged state of the two clamps. I.e., the distance from the hinge of catch 30 to catch bolt 40 plus the radius of catch bolt 40.

To save labor during snapping, the free end of clip 30 is extended along rounded end 306 as shown in fig. 8. The extending edge 307 and its adjacent edge form a sharp corner 304, when clamping, the sharp corner 304 of the buckle contacts the clamping bolt 40 first, because of the lever principle, the arm of force of the buckle 30 is longer than that of the clamping bolt 40, so the buckle 30 can be pushed to the clamping direction with smaller force.
