ABSTRACT:
An opener head retainer comprises a handle held by users; a front end of the handle having a receiving groove; an operation portion capable of being inserted into the receiving groove; a receiving portion formed by a casing, an inserting disk, an elastomer, and a cover. An inner side of the casing has a receiving space for receiving the inserting disk and the elastomer. A periphery of the through hole has two lower inclined resisting sheets. A lower side of the inserting disk is enclosed by two upper inclined resisting sheets capable of resisting against the two lower inclined resisting sheets so to control the vertical orientation of the inserting disk in the casing. Each of the opener heads is placed between a corresponding one of the clamping groove and a corresponding one of the receiving openings.
