Improved bidirectional cantilever clamp

The utility model relates to an improved bidirectional cantilever clamp. The device comprises a rod-type connecting body, a supporting cantilever and a net-shaped base, the supporting cantilever is U-shaped and is arranged on the second abutment tooth; the front tooth and the rear tooth are respectively a third abutment and a first abutment, the high points of the cheek side appearance of the support cantilever respectively extend towards the first abutment and the third abutment to form a distal retention arm and a proximal retention arm, and the tail ends of the distal retention arm and theproximal retention arm enter the inverted concave areas of the corresponding abutment to form retention; a rod-type connecting body is arranged at the buccal mucosa of the second abutment, the supporting cantilever is connected with the rod-type connecting body, and the lower end of the rod-type connecting body transversely extends and is connected with the adjacent net-shaped base plate. According to the improved two-way
