Angle adjustable holder

Abstract

An angle adjustable holder comprises a base, a holding element, a first friction element, a second friction element, a springiness element, a bearing element, a first combination element and a second combination element. The base has a first connecting portion and a second connecting portion. The first friction element has a first friction surface, and the second friction element has a second friction surface. The second friction surface and the first friction surface are in contact. The first combination element passes through the first connecting portion, the second connecting portion, the pivotally connecting portion of the holding element, the bearing element, and the springiness element. The second combination element is combined with the first combination element such that the springiness forces the first friction surface to contact the second friction surface for providing a resistance when the holding element is pivotally rotated.

1 . An angle adjustable holder, comprising: 
 a base having a first connecting portion with a first through hole and a second connecting portion with a second through hole;    a holding element for carrying an external device, wherein the holding element comprises a pivotally connecting portion pivotally connecting to the first connecting portion and the second connecting portion of the base;    a first friction element having a first friction surface and installed inside the first through hole;    a second friction element having a second friction surface and installed inside the pivotally connecting portion, wherein the second friction surface and the first friction surface are in contact;    a springiness element disposed inside the pivotally connecting portion;    a bearing element disposed inside the second through hole;    a first combination element passing through the first connecting portion, the second connecting portion, the pivotally connecting portion, the bearing element, and the springiness element; and    a second combination element combined with the first combination element such that the springiness forces the first friction surface to contact the second friction surface so as to provide a resistance when the holding element is pivotally rotated.

         6 . The angle adjustable holder of  claim 4 , wherein the adhesive portion comprises a Velcro.  
     
     
         7 . The angle adjustable holder of  claim 1 , further comprising: 
 a covering element disposed on the outer sides of the first connecting portion and the second connecting portion of the base.    
     
     
         8 . The angle adjustable holder of  claim 1 , wherein the first combination element is a screw.  
     
     
         9 . The angle adjustable holder of  claim 1 , wherein the second combination element is a screw nut.  
     
     
         10 . The angle adjustable holder of  claim 1 , wherein the holding element further comprises: 
 a holding portion for carrying the external device.    
     
     
         11 . An angle adjustable holder, comprising: 
 a base having a first connecting portion with a first through hole and a second connecting portion with a second through hole;    a holding element for carrying an external device, wherein the holding element comprises a pivotally connecting portion pivotally connecting to the first connecting portion and the second connecting portion of the base;    a first friction element installed inside the first through hole, wherein the first friction element has a first friction surface;    a second friction element installed inside the pivotally connecting portion, wherein the second friction element has a second friction surface contacting the first friction surface;    a springiness element disposed inside the pivotally connecting portion;    a bearing element disposed inside the second through hole;    a screw passing through the first connecting portion, the second connecting portion, the pivotally connecting portion, the bearing element, and the springiness element; and    a screw nut combined with the screw such that the springiness forces the first friction surface to contact the second friction surface so as to provide a resistance when the holding element is pivotally rotated.    
     
     
         12 . The angle adjustable holder of  claim 11 , wherein the first friction element and the second friction element are ratchets.  
     
     
         13 . The angle adjustable holder of  claim 11 , wherein the springiness element is a spring.  
     
     
         14 . The angle adjustable holder of  claim 11 , further comprising: 
 an adhesive portion disposed on the base to adhere the angle adjustable holder onto a surface.
