Crescent connecting assembly
The invention discloses a crescent connecting assembly. The crescent connecting assembly comprises a connector, a connecting base and a locking clamp. One end of the connector is in the shape of an arc with convex grooves in two sides. The other end of the connector is a plane provided with one or more positioning convex stands. The angle-adjustable locking clamp is arranged in the middle of the connector. One end of the connecting base is in the shape of an arc with convex grooves in two sides. The other end of the connecting base is a plane provided with one or more positioning concave stands. An arc-shaped cavity which can contain the locking clamp is formed in the middle of the connecting base. The locking clamp is fixed to the middle of the connector. The head of the locking clamp is pulled to rotate by rotating an internal hexagonal hole in the tail end of the locking clamp by means of an internal hexagonal wrench, so that the connector is connected with or separated from the connecting base. The crescent connecting assembly is ingenious and novel in structural design; disassembly and assembly of a plate are achieved through the locking clamp, the surface of the assembled plate is complete, disassembly is free, no processing mark is left, and operation is easy and convenient.
