TW201932253A - Release valve tool and kit thereof that comprises first and second connectors that are connected to each other in cascade and are received in a rotating member - Google Patents

Abstract

The present invention provides a release valve tool, which allows a first connector and a second connector that serves as a connection tube between an external tube and a release valve to extend, in a condition of being connected to each other in cascade, into a rotating member. It also allows the rotating member to rotate relative to the first connector and the second connector without causing interference with the first connector and the second connector. As a result, when the rotating member is applied to rotate the release valve, in addition to not causing the first connector and the second connector to move together, the first connector is elastically wrapped around the circumference of the release valve between the first connector and the release valve that are connected to each other in cascade due to the elasticity of the first connector that allows for deformation. When the release valve is caused to simultaneously rotate with the rotating member, the circumference of the release valve and the inner circumference of the first connector slide relative to each other without allowing the first connector to rotate with the release valve for preventing the external tube from twisting.

The first connecting member has an elastically deformable tubular first body for maintaining the tightness between the first connecting member and the mouthpiece and allowing relative rotation therebetween. The first body portion can be movably penetrated into the rotating member, so that the mouthpiece and the first body portion are not blocked by the rotating member when performing relative rotating activities with each other. Further, a suitable gap may be formed between the first body and one of the tubular positioning portions of the rotating member of the wearing sleeve, except that the first body portion is allowed to be adapted to the enlarged deformation generated when the mouthpiece is worn. It is also possible to ensure a margin of rotation of the mouthpiece relative to the first body.

Furthermore, in order to prevent interference between the first connecting member and the second connecting member and the rotating member, the second connecting member and the rotating member are loosely movable and movable, and are loosely matched. The combined structure can be achieved by the size design. In a specific implementation, the second connecting member can have a tubular second body and the outer diameter of the second body is smaller than the positioning. An inner diameter of one end of the tube shaft, so that the second body portion is formed between the outer wall of the second body portion and the inner wall of the positioning portion when extending through the end of the tube shaft of the positioning portion The gap is such that the second body portion and the positioning portion are not connected to each other.
