Adjustable Supporting Device

Abstract

A supporting device includes a supporting foot, and a clip module for fixing the supporting foot. The clip module includes a base, a push button affixed in a slidable manner to the base, and two sliding blocks affixed in a slidable manner to the base for clipping the supporting foot while the push button moves to a predetermined position relative to the sliding blocks.

1 . An adjustable supporting device comprising:
 a supporting foot;   a clip module for fixing the supporting foot, the clip module comprising:
 a base; 
 a push button affixed to the base in a forward-and-backward slidable manner; and 
 a sliding block affixed to the base in a leftward-and-rightward slidable manner and utilized for clipping the supporting foot while the push button moves to a predetermined position relative to the sliding block. 
   
   
   
       2 . The adjustable supporting device of  claim 1  further comprising:
 a first spring for pushing the supporting foot; and   a sleeve for positioning the first spring and the supporting foot to move the first spring and the supporting foot along an axial orientation of the sleeve.   
   
   
       3 . The adjustable supporting device of  claim 2  wherein the clip module further comprising:
 a cover, one terminal of the cover being affixed to the sleeve while another terminal of the cover being affixed to the base and for hedging a maximal movement of the supporting foot.   
   
   
       4 . The adjustable supporting device of  claim 2  further comprising:
 a damper for providing a resistance to slowly push the supporting foot while the supporting foot is pushed by the first spring .   
   
   
       5 . The adjustable supporting device of  claim 4  wherein the clip module further comprising:
 a cover, one terminal of the cover being affixed to the sleeve while another terminal of the cover being affixed to the base and utilized for hedging a maximal movement of the supporting foot;   a second spring utilized for pushing the push button to a predetermined position relative to the sliding block; and   a third spring utilized for pushing the sliding block to clip the supporting foot with a predetermined force;   wherein the supporting foot has threads, and the sliding block has corresponding threads; when the sliding block clips the supporting foot, the supporting foot fine-tunes a relative position between the supporting foot and the sliding block in a rotatable manner; and the adjustable supporting device is for adjusting an angle of inclination of a projector.   
   
   
       6 . The adjustable supporting device of  claim 1  wherein the clip module further comprises:
 a second spring for pushing the push button to the predetermined position relative to the sliding block.   
   
   
       7 . The adjustable supporting device of  claim 1  wherein the clip module further comprises:
 a third spring for pushing the sliding block to clip the supporting foot with a predetermined force.   
   
   
       8 . The adjustable supporting device of  claim 1  wherein the supporting foot has threads, and the sliding block has corresponding threads; when the sliding block clips the supporting foot, the supporting foot fine-tunes a relative position between the supporting foot and the sliding block in a rotatable manner. 
   
   
       9 . The adjustable supporting device of  claim 1  wherein the adjustable supporting device is utilized for supporting a projector. 
   
   
       10 . An adjustable supporting device comprising:
 a supporting foot;   a spring for pushing the supporting foot;   a sleeve for positioning the spring and the supporting foot to move the spring and the supporting foot along an axial orientation of the sleeve; and   a clip module affixed to the sleeve for fixing the supporting foot.   
   
   
       11 . The adjustable supporting device of  claim 10  further comprising:
 a damper for providing a resistance to slowly push the supporting foot when the spring pushes the supporting foot.   
   
   
       12 . The adjustable supporting device of  claim 10  wherein the supporting foot has threads, and the clip module has corresponding threads; when the clip module fixes the supporting foot, the supporting foot fine-tunes a relative position between the supporting foot and the clip module in a rotatable manner. 
   
   
       13 . The adjustable supporting device of  claim 10  wherein the adjustable supporting device is for supporting a projector. 
   
   
       14 . A clip module comprising:
 a base;   a push button affixed to the base in a forward-and-backward slidable manner; and   a sliding block affixed to the base in a leftward-and-rightward slidable manner for clipping an object when the push button moves to a predetermined position relative to the sliding block.   
   
   
       15 . The clip module of  claim 14  further comprising:
 a first spring for pushing the button to the predetermined position relative to the sliding block.   
   
   
       16 . The clip module of  claim 14  further comprising:
 a second spring for pushing the sliding block to clip the object with a predetermined force.
