Description:
BACKGROUND OF THE INVENTION 
     (a) Field of the Invention 
     The present invention is related to a pen with variable penholder styles, and more particularly, to one that can be applied to a ball pen, a steel ball pen, an automatic pen, a fountain pen or any other writing tool to allow the arrangement of the style, pattern or collar combination for the penholder as desired. 
     (b) Description of the Prior Art 
     A ball pen, steel ball pen or automatic pen generally available in the market is usually comprised of a hollow penholder, a pen clip and at least one refill; and a button one the top of the penholder in case of a mechanical pen. A hollow conic pen point cover is screwed to the upper end of the penholder with the pen point exposed out of the pen point cover. 
     However, the design for the appearance of the pen is pre-determined making the style of the penholder dull and monotonous, and is difficult to be identified among a bunch of pens. The user would have to bother to mark on the penholders one by one. In a time when people are pursuing demonstration of individual style, pen certainly is included as one of the objects to be given with the style the user thinks most fits for him. The prior art of the penholder fails the needs of the contemporary people. 
     SUMMARY OF THE INVENTION 
     The primary purpose of the present invention is to provide a pen with variable penholder styles, particularly on the innovative improvement for the penholder, which allows its user to arrange the style, color, or pattern of penholder as desired, and further to make the pen easier to identify while maintaining the effect of personal style 
     To achieve the purpose, the front of the penholder is made a hollow insertion tube in smaller diameter to accommodate a refill. Multiple decoration rings are inserted on the peripheral of the insertion tube of the penholder. Multiple grains and pits are respectively provided at the front and the rear end of each decoration ring to allow each ring to be turned around for adjustment or positioning. A special color, strip or pattern is provided on the circumferential surface of each ring. A pen point cover is screwed to the front end of the insertion tube and those multiple decoration rings are locked to one other by means of those grains and pits provided to each decoration ring under the compression of the pen point cover to demonstrate a pen holder with personal character from the combination of style, pattern or color as one chooses. 
     Another purpose of the present invention is to provide a pen with variable penholder styles that satisfy the demonstration of personal style and permit easy identification. To achieve the purpose, multiple troughs are provided on the peripheral of each decoration ring and each trough is planted in a silicon ornament piece to allow the user to decorate the penholder with different styles of ornament piece as desired and the overall appearance of pattern or letter can be adjusted by turning the rings whenever one feel likes to. 
     Another purpose yet of the present invention is to provide a pen with variable penholder styles that allows wide range of combination of the ornament pieces. To achieve the purpose, any letter, pattern, stripe or color can be provided on the surface of the ornament piece.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIGS. 1,  2 , and  3 , a pen with variable penholder styles of the present invention is essentially comprised of a penholder  1 , a refill  2 , multiple decoration rings  3  and a pen point cover  4 . Wherein, the penholder  1  as illustrated in FIG. 1 relates to a hollow tube having provided at its front section a hollow insertion tube  11  in smaller diameter that that of the remaining part of the penholder  1 . A threaded section  12  is provided at the front end of the insertion tube  11 , an upper section  13  of the penholder in larger diameter is connected to the rear of the insertion tube  11 , and multiple pits  14  are provided at equal distance on the front end surface of the upper section  13  of the penholder. In the present invention, the penholder  1  is provided to accommodate elements of the refill  2 , those decoration rings  3 , and the pen point cover  4  by the insertion tube  11 . However, other preferred embodiments of the present invention may further include a pen clip  15 , or have the penholder  1  made with a fixed refill, or a retractable refill by twisting or by compression. 
     The refill  2  as illustrated in FIG. 1 contains the ink or pencil lead and is placed into the hollow insertion tube  11  of the penholder  1  with the pen point exposed out of the front end of the insertion tube  11 . However, the refill  2  may be related to that for a ball pen, a steel ball pen, automatic pencil lead or any other type of refill. All these refills are of the prior art and will not be elaborated herein. 
     The decoration ring  3  as illustrated in FIG. 1 relates to a circular ring having at its center provided with an opening  31  and multiple ornament pieces  32  on the circumferential surface. Multiple pits  33  are provided on one end surface of the decoration ring  3  and multiple evenly distributed grains  34  to match those pits  33  are provided on the other end surface. The surface of each ornament piece  32  is provided with color, pattern, letter, stripe or other graphic design either by printing, coating or engraving method so that when multiple decoration rings  3  are abutted to one another, variable appearances are created on the penholder  1 . 
     The pen point cover  4  as illustrated in FIG. 1 relates to a conic hollow object having at its center provided with a through hole  41  to permit the exposure of the refill  2  out of the front end of the insertion tube  11 . Multiple decoration rings  3  are inserted side by side in the same direction onto the peripheral of the insertion tube  11  with the pen point cover  4  having its threaded section  42  at the rear to be engaged with the threaded section  12  at the front end of the insertion tube  11 , and the tip of the refill  2  exposed out of the front end of the insertion tube  11 . Upon loosening the pen point cover  4 , any of those decoration rings  3  can be turned around to change for another style for the appearance of the penholder  1  while upon tightening up the pen point cover  4 , all those decoration rings  3  are packed to hold steady the style of the penholder  1 . 
     As illustrated in FIGS. 4 and 5, each decoration ring  3  is related to a circular ring  35  having at its center provided with an opening  31 , multiple pits  33  being evenly provided on one end surface and multiple corresponding grains  34  being provided on the other end surface of the decoration ring  3 . Furthermore, multiple troughs  36  having wider interior and narrower exterior are provided on the circumferential surface of the decoration ring  3  to be respectively planted an arc ornament piece  32  provided with an insertion bit  321  at the bottom. Now referring to FIGS. 6 and 7, a decoration ring  3  of the present invention is related to a circular ring  35  having at its center provided with an opening  31 , and multiple dovetail grooves  37  being evenly distributed on one end surface to respectively receive their corresponding arc ornament pieces  32  each provided with at its bottom a dovetail tongue  332 . However, the ornament piece  32  may be made of rubber, silicone, plastic or other material in once piece and either printed, coated or engraved upon its surface any color, letter, stripe as illustrated in FIG. 8 or pattern as illustrated in FIG.  9 . Once multiple decoration rings  3  are abutted and inserted onto the peripheral of the insertion tube  11 , creating an appearance in special style by the color, letter, stripe, or pattern for the penholder  1 . Furthermore, to suit personal like and improve the identity of the pen, those multiple decoration rings  3  may be turned around or replaced with other types of ornament pieces  32  for demonstrating other styles as desired. 
     Referring to FIG. 11 for the adjustment modes by turning around each decoration ring  3 , the pen point cover  4  is loosened first to permit slight spacing between two abutted decoration rings  3  while those grains  34  on one end of a decoration ring  3  are disengaged from those pits  33  from another decoration ring  3 . By turning around any decoration ring  3  or multiple decoration rings  3 , effects of color, letter and pattern are displayed according to personal favors. Upon completing the adjustment, tighten up the pen point cover  4  again to compress all the decoration rings  3  to abut to one another as illustrated in FIG. 10 with those grains  34  to be engaged to their respective pits  33  on the other decoration ring  3 , thus to secure the color, letter, or pattern as adjusted. 
     The threaded section  12  at the front end of the insertion tube  11  is provided for engaging to another threaded section  42  provided at the rear end of the pen point cover  4  as illustrated in FIGS. 1 and 10. In practice, an externally threaded section  12  is provided to the peripheral of the front end of the insertion tube  11  and an internally threaded section  42  is provided in the hole at the rear end of the pen point cover  4  for fastening the insertion tube  11  to the pen point cover  4 . However, as illustrated in FIGS. 12 and 13, the same fastening effect is also achieved by having an internally threaded section  12 ′ provided on the inner wall of the hole at the front end of the insertion tube  1 , a protruded shaft  43  provided at the rear end of the pen point cover  4 , and an externally threaded section  42 ′ provided to the peripheral of the protruded shaft  43 . 
     It should be noted that the pen of the present invention comprised of the penholder  1 , the refill  2 , multiple decoration rings  3  and a pen point cover  4  may be applied to a ball pen, a steel ball pen, an automatic pen or any other type of pen simply by replacing the refill  2 ; and the preferred embodiment of the present invention also include the structure of a fixed refill, and a retractable refill either by twisting or compressing. Whereas all these preferred embodiments are related to the prior art and incorporated into the characteristics of the present invention as described above, the preferred embodiments of the present invention certainly are not limit to those disclosed herein.
