Claims

[Scope of Claim for Utility Model Registration] 1. The hose band is created by rotating a tightening bolt into which a nut that is attached to the movable end of the hose band is screwed so that the nut is threaded toward the head side of the tightening bolt. In a socket for a tightening tool for tightening a bolt, a guide tube slidable in the axial direction of the socket body is provided on the outer periphery of the socket body that can fit into the head of the tightening bolt, and a tail end of the guide tube is provided. An engaging ball is provided on the outer periphery of the socket body, and the engagement ball is biased radially inward by an O-ring attached to a concave groove formed on the outer periphery of the tail end. a first engaging groove that receives the engaging ball when it is in a pulled out position where it protrudes forward; and a first engaging groove that receives the engaging ball when the guide tube is in a pushed-in position where its tip does not protrude forward of the socket body. A socket for a hose band tightening tool, characterized in that a second engagement groove for receiving the hose band is formed. 2. A socket for a hose band tightening tool according to claim 1, wherein the first engagement groove is formed in multiple stages in the front and rear.
