Abstract

An improved structure of a mobile phone hand-free holder, includes a holder, an upper casing, a lower casing, a resilient locking seat and a press lever; a cross link pivoted to the center; an insertion protruding from end of the pivot to slide in a lateral slide way in the upper casing, both ends of the cross link being connected respectively to both sides of the holder; one side of the holder is serrated at the edge; the locking seat being provided by the serration to have two stoppers protruding into the serration to force the holder to only press inwardly to be held in position; an earphone socket also functioning as a switch to control transmission of an incoming call to be received by a cordless earphone or an external speaker or a car radio; the lateral displacement of the cross link in the slide way to deflect the center to hold a mobile phone with its plug socket not provided at the center.
