摘要： An improved wand for connecting a vacuum cleaner and power nozzle is disclosed. The wand includes a sheath, an upper wand assembly received in the sheath and detachably connected to the vacuum cleaner hose handle, and a lower wand assembly received in the sheath and releasably connected therein to the upper wand assembly. A resilient plug body is provided for attachment to the hose handle to be connected to the cord of the sheath. The plug body contains at least two electrical connectors separated by a slit to provide a limited degree of flexibility in the plug body to insure a good connection despite any possible minor misaligment with the opposing connectors on the cord. The upper end of the lower wand assembly has a leaf spring with a button on its underside protruding through a hole in the lower wand assembly to engage a similar hole in the upper wand assembly. The sheath has an axially slidable cam element for sliding under and raising the free end of the spring another version, the wand assemblies are connected by means of an omega spring in the upper assembly having a button protruding through holes in both assemblies. In this version, the sheath has a depressable release element having an S-spring on its underside to depress the omega spring and release the lower assembly.
