Abstract:
A network camera holder includes an universal coupling for fixing a network camera and a clinch. The clinch is configured to hook a thin frame and, also, can reverse outward on a pivot in order to grip a thicker frame. The clinch can also be spread out to place the holder directly on a flat surface.

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a holding structure of a network camera, wherein a fixture fixed at one side of a holder pivots to control gripping thickness. 
   2. Description of the Prior Art 
   Direct network communication via video chat and conferencing using a network camera and the supporting computer software, is the most common communication method applied by current corporations. However, when conducting network video communication the positioning of a network camera is an important consideration. Usually, a network camera is positioned on a desktop or monitor of a computer by gripping and locking. However, it may be limited by shape and thickness due to the distance between the gaps of clips and locks. However, computer screens are increasingly produced in unique shapes and with geometrical curves. Therefore, the old positioning method for network cameras can not be applied to these variable products, so further improvement is needed. 
   SUMMARY OF THE INVENTION 
   I. Problem to Solve 
   Prior art network camera holders are inconvenient to assemble due to the fixed size of the clinching gap, so, such structure is not practical. 
   Due to great changes and innovations in the appearance of computers it is very difficult to apply only one fixing method to place or position a network camera, which may limit its application. 
   II. Solutions 
   a. Fixture producing counterforce by a compression spring is fixed at one side of the holder of this invention, and another side has a pivoting clinch which grips using both the block side of clinch, and the hook side of the clinch after this clinch reverses outward to spread out, so that it can grip onto objects of different thickness. 
   b. This invention can open the clinch to allow the fixture to be placed on a table, so, its application is convenient. 
   c. This invention includes a universal coupling to fix the network camera so as to adjust the angle of this network camera and expand the field of vision. 
   d. This invention can clip onto a LCD or Notebook computer and automatically adjust its griping according to different thickness, and it can even directly be placed on a thick CRT screen.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Please refer to  FIG. 1  and  FIG. 2 . Holder  1  is composed of upper and lower cover  11 ,  12 . Fixture  2  is assembled at one side and clinch  3  is pivoted at its opposite side, wherein universal coupling  111  is fixed onto upper cover  11 , fixing seat  112  on this universal coupling  111  locks the network camera so the field of vision can be adjusted. Pivot seat  123  is then fixed at one side to pivot clinch  3 . 
   Please refer to  FIG. 1 . Two ends of lower cover  12  includes set holes  121 , runner  1211  is set respectively at two sides, and spacing hole  122  is made between two holes  121 . Pivot seat  123  is set opposite to hole  121 . 
   Please refer to  FIGS. 1 ,  3  and  6 . Pull rod  21  is respectively fixed at two sides of fixture  2 , spacing fixture  20  is set between pull rods  21 , wherein one piece of compression spring  22  is respectively placed onto pull rod  21  to lock it at its end with screw  23  so as to block compression spring  22 . Pull rod  21  of fixture  2  and compression spring  22  are put into this runner  1211 , and one end of compression spring  22  leans against an internal edge of the above said hole  121 . Screw  23  leans against another end, so that, as fixture  2  is pulled out to press compression spring  22  to produce counterforce, the gripping side  24  of fixture  2  can impose gripping force on the object. 
   Please refer to  FIG. 1  and  FIG. 3 . A            -shaped heavy block  4  is assembled between two runners  1211 , and spacing board  20  of fixture  2  is embedded into gap  41  so as to prevent displacement when fixture  2  moves forward and backward. Therefore, holder  1  is more stable.
   Please refer to  FIG. 1 ,  FIG. 4 ,  FIG. 5  and  FIG. 7 . Pivot  31  is respectively fixed at two sides of one end of clinch  3 , and block  30  is assembled at a proper position between the two pivots  31  and may be embedded into block wall  124  of pivot seat  123  so as to limit the spreading out of clinch  3  when pivot  31  strides over pivot seat  123  of the above said lower cover  12 . Hook  32  with block side  321  and hook side  322  is set at one end of pivot  31  under lower cover, so that block side  321  is used to grip with gripping side  24  of the fixture  2 , and hook side  322  is used to grip with gripping side  24  of the fixture  2  as the clinch  3  is pivoted about the axis of pivot  31 . 
   Please refer to  FIG. 1  and  FIG. 4 . Pivot  31  can cover one piece of the soft sleeve  311 , which may produce a proper binding force on soft sleeve  311  when closing upper and lower cover  11 ,  12 . Pivot  31  thereby produces resistance so that clinch  3  can be positioned properly in any position while avoiding any shaking in adjustment accordingly. 
   Please refer to  FIG. 1 ,  FIG. 6  and  FIG. 8 . Fixture  2  of holder  1  applies block side  321  of clinch  3  to lean against an object A according to its thickness. Meanwhile, pull rod  21  presses compression spring  22  so as to produce a counterforce, and gripping side  24  of fixture  2  and block side  321  of clinch  3  grip object A. Hook  32  of clinch  3  is then used to support holder  1  so that it can be positioned onto object A, and universal coupling  111  is fixed at holder  1  to allow the adjustment of the angle of the network camera C so as to expand the field of vision accordingly. 
   Please refer to  FIG. 7 . Clinch  3  can reverse so that the hook side  322  of hook  32  strides over object A, and the gripping side  24  of fixture  2  and hook side  322  of hook  32  grips object A based on the pulling of fixture  2 , so that holder  1  is stably fixed on object A. 
   Please refer to  FIG. 7  and  FIG. 8 . The clinch  3  provides support to holder  1 , and the above said fixture  2  adjusts the thickness according to the gripped object A so that it is applicable to objects of different thickness. Furthermore, as clinch  3  reserves to spread out, it can be directly placed on a plane (such as table) using fixture  2  and hook  32  of clinch  3 , and the possible applications of this invention are thereby increased accordingly (shown as  FIG. 6 ).
