A TAG FIXTURE FOR ASSEMBLING STRINGS IN BIDIRECTIONAL DIRECTIONS

摘要

PURPOSE: A tag ring is provided to allow a string to be inserted and assembled from both sides much faster and easier. CONSTITUTION: A tag ring (400) includes: a groove that has a cylinder shape and is penetrated from the both ends in a length direction; a stepped portion which is cut in the determined thickness by the determined section from the groove entrance of both sides toward the center portion of the length direction; a slit portion (430) which is formed at the determined intervals from the groove entrance of one side in which the stepped portion is formed toward the groove entrance in which the opposite stepped portion is formed; and at least one pair of protrusions (441,442) protruding on any one or both of slit surfaces of two slit surfaces which oppose each other in the slit portion. The stepped portion is cut so that the thickness of a cut portion is thicker than that of the remaining portion, the thickness of a cut portion is thinner than that of the remaining portion, or thickness of a cut portion is same as that of the remaining portion. The determined section that is cut from the stepped portion is within the section from the groove entrance before the protrusion, and is the remaining section except for the determined section forming the slit portion. The protrusion has a side that has a relatively gentle inclination so that when a string (410) inserted from a groove entrance enters the center portion, the string is not interrupted, and a side (431) that has the relatively steep inclination so that when the inserted string escapes to the groove entrance, the string is interrupted.
