APPARATUS FOR COUPLING CLAMP AND HEAD

摘要

PURPOSE: A coupling apparatus for a clamp and a head is provided to easily couple the clamp to the head and to reduce the tolerance and gap formed between the clamp and the head. CONSTITUTION: Lockers(23,25) of a head(24) are meshed with a cap(22) of a clamp(21) in such a manner that the clamp(21) is detachably coupled to the head(24). The clamp(21) has a conical member(27), which is engaged with a taper surface(26) of the head(24). When the conical member(27) of the clamp(21) is engaged with the taper surface(26) of the head(24), the clamp(21) is automatically introduced into a central line(9) of the head(24), thereby reducing the tolerance and gap between the clamp(21) and the head(24). A spring is provided in the lockers(23,25) so that an opening is automatically opened or closed.
