The purpose is that the small stepped hole is a guide hole and plays a role in guiding the stud pull rod (5), and the big stepped hole is a gas channel; the sliding key groove (12a) and the rotating key groove (12b) are used for axial sliding and circumferential rotation of the cylindrical sliding block (10); the tower-shaped structure is in interference fit with the inner diameter of the medical rubber tube (14) to achieve the sealing and anti-falling functions.
The outer surface of one end of the transition joint (15) is of a tower-shaped structure, the interior of the transition joint is of an internal thread structure, the other end of the transition joint is of an external thread structure, and a through hole is formed in the middle of the transition joint. The anti-drop medical hose aims to achieve the sealing and anti-drop effects of the interference fit of the tower-shaped structure and the inner diameter of the medical hose (14); the internal thread is used for connecting a stud pull rod (5); the through hole is an installation process hole (15a), and when the through hole is installed with the handle ball-shaped nut (17), the wrench pin is inserted into the through hole to have a rotation stopping effect.
The dumbbell-shaped handle (8) is dumbbell-shaped in appearance. Its purpose is that the appearance design dumbbell type accords with human engineering, promotes use comfort.
