ABSTRACT:
A locating and clamping apparatus can prevent spatter from entering the clamp body through a spatter discharge hole. A longitudinal groove is formed in a side surface of the clamp body so as to communicate with both a spatter discharge hole and a hole for supporting a fulcrum pin. A spatter protecting cover having an upper cover member and a lower cover member is fitted in the longitudinal groove. The upper cover member of the spatter protecting cover prevents the fulcrum pin from coming off, and the lower cover member of the spatter protecting cover opens or closes the spatter discharge hole.
