Valve connector compatible with multiple valve types

Abstract

This invention relates to a nozzle connector applicable to various types of nozzles, comprising a housing and a clamping device. The housing includes an outer sleeve, a first lever, and a second lever. The outer sleeve has a through groove and is provided with an operating end and a sleeve end. The first lever and the second lever are pivotally mounted on the operating end. The clamping device includes a push seat disposed in the through groove. When the first lever and the second lever are in the released position, the distance from the push seat to the sleeve end forms a first depth. When the first lever is in the clamping position, the distance from the push seat to the sleeve end forms a second depth, which is less than the first depth. When the second lever is in the clamping position, the distance from the push seat to the sleeve end forms a third depth, which is less than the second depth. The nozzle connector, through the above structure, can be used for various types of nozzles.
