Novel collapse-proof tooth shell device

The utility model discloses a novel collapse-proof tooth shell device which comprises a U-shaped clamp and a tooth shell clamp body, the tooth shell clamp body is an H-shaped steel plate, a fixed plate is arranged on the upper end face of the tooth shell clamp body, the two sides of the fixed plate are provided with threaded connecting holes, and the tooth shell clamp body is fastened on a ceiling beam through the U-shaped clamp. The novel collapse-proof tooth shell device solves the problem of collapse of a ceiling beam tooth shell and is simple in design, reasonable in structure and capable of being directly installed on the ceiling beam with the tooth shell collapsed to replace a previous tooth shell, the ceiling beam is not required to be replaced, and therefore the working intensity of workers is lowered.
