Adjustable clamp device

Abstract

An adjustable clamp device for adjusting a length to clamp positioning is disclosed. The adjustable clamp device has a chassis, an adjusting element and an elastomer. The chassis has a pressing portion on a side thereof and a limiting portion on another side thereof. The limiting portion has a sliding space for mounting adjusting element, and the adjusting element comprises a sliding base and a buckling portion correspondingly positions on the two sides of the adjusting portion. The elastomer is positioned in the buckling portion for elastically moving in the sliding space.

         2 . The adjustable clamp device according to  claim 1 , wherein said sliding space further comprises a plurality of gear-like buckling grooves and a long track groove at two sides respectively. 
     
     
         3 . The adjustable clamp device according to  claim 2 , wherein said sliding base comprises a bent hook-shaped clamping portion at one side and a buckling block formed on a surface thereof, said buckling portion comprises an inlaying hole for engaging with said buckling block and a sliding block formed on an outer side adjacent to said inlaying hole for sliding in said long track groove of said sliding space. 
     
     
         4 . The adjustable clamp device according to  claim 2 , wherein said elastomer is bent to form a tip; said buckling portion comprises a chamber for receiving said elastomer and a slot formed on a side in said chamber for protruding said tip against said gear-like buckling grooves of said sliding space. 
     
     
         5 . The adjustable clamp device according to  claim 1 , wherein said chassis comprises a receiving space adjacent to said pressing portion for receiving said sliding base of said adjusting element. 
     
     
         6 . The adjustable clamp device according to  claim 1 , wherein said chassis comprises a positioning element, a recess set adjacent said limiting portion for mounting said positioning element in position and two tracks positioned at two lateral sides of said recess, and each of said tracks has a partition; said sliding base of said adjusting element comprises a inlaying space and two fitting blocks in said inlaying space for engaging with said partitions in said tracks. 
     
     
         7 . The adjustable clamp device according to  claim 1 , further comprises a positioning set having two jointing portions and a elastic element; said chassis comprises two receiving portions at back side of said pressing portion assembled with said jointing portions of said positioning set for mounting said elastic element between said positioning portions and said jointing portions. 
     
     
         8 . The adjustable clamp device according to  claim 7 , wherein said positioning set comprises two axial portions for axially mounting a supporting rod; said chassis comprises a positioning element with at least one notch for lodging said supporting rod. 
     
     
         9 . The adjustable clamp device according to  claim 7 , wherein said jointing portions each have a axial hole for axially mounting an axle, and a stopper is positioned on a side adjacent to said jointing portions. 
     
     
         10 . The adjustable clamp device according to  claim 8 , wherein said axial portions each have a groove at an interior thereof, a positioning plate positioned on a side near said jointing portions, and a positioning hole on another side away from said jointing portions. 
     
     
         11 . The adjustable clamp device according to  claim 9 , wherein said receiving portions each have a axial hole corresponding to said axial holes of said positioning set and a stopper positioned between said two receiving portions. 
     
     
         12 . The adjustable clamp device according to  claim 1 , wherein said pressing portion comprises a plurality of protrusions for providing a skidproof effect. 
     
     
         13 . The adjustable clamp device according to  claim 7 , wherein said elastic element is a folded spring with two jointing holes and two holding portions extended from said jointing holes. 
     
     
         14 . The adjustable clamp device according to  claim 7 , wherein said positioning set can further be assembled with a case, and said case comprises an embedding portion on a side, a plurality of buckles on a flange of said embedding portion, an arch-shape limiting block formed adjacent to said embedding portion, and a receiving chamber formed apart from said embedding portion for receiving an electronic device. 
     
     
         15 . The adjustable clamp device according to  claim 14 , wherein said electronic device can be a mobile phone, a palm video game player, a PDA, a MP3 player and a portable video device.
