     PREFERRED EMBODIMENT  
      The current invention shall be further described in combination with the attached figures of the preferred embodiment.  
      As shown in  FIG. 1 , the current invention of a dual-purpose pen for painting comprises a hollow penholder  10 , a watercolor pen  20 , a, separator  40 , a crayon  30 , a crayon holder  50  and a crayon cap  60 ; said watercolor pen  20  comprises a pen tip  21  and a core  22  holding ink. Said separator  40  is set inside the penholder  10  and separates the penholder  10  into two sections: one section holing the watercolor pen  20 , one end of said tip  21  is connected with said core  22  holding ink and the other end of said tip  21  extends out of the other end of said penholder  10 ; one end of said crayon  30  is inserted into said crayon holder  50  to be accommodated into the other section of said penholder  10 , said crayon cap  50  is connected to the other end of said penholder  10  and the tip of said crayon  30  extends out of said crayon cap  50 . In this invention, said crayon  30  can be replaced by a color pencil at the same size.  
      As shown in  FIG. 1 , said penholder has a shoulder  11  at the border of the two sections and said separator  40  has a “ ” shaped longitudinal section and said separator  40  is anastomotic with said shoulder  11 . As shown in  FIG. 1 , the section of said penholder  10 , which accommodates said crayon  30 , has interior screw  11  set on its inner wall while said crayon holder  50  has exterior screw  51  on its outer wall to match said interior screw  11 ; said crayon cap  60  is articulated to the penholder  10  and this crayon holder  60  has a thin and long strip-shaped toggle rod  61  close to the end of the penholder  10 . Furthermore, the toggle rod  61  is inserted between said crayon holder  50  and the inner wall of the penholder  10 ; in case that said crayon cap  60  is turned clockwise or counter-clockwise, said toggle rod  61  will make the crayon holder  50  rotate to move in or out of said penholder  10 , thus making said crayon  30  contract into or extend out of the cap  60 . As the crayon will become shorter in use owing to wear and loss, the structure of the above mentioned crayon holder  50 , crayon cap  60 , toggle rod  61  and interior and exterior screws makes it possible to make the crayon extend out of the penholder  10  and cap  60  even it becomes short, thus for full use of crayons. And when the crayon  30  is not in use, it can be contracted into the penholder  10  and cap  60 , protecting it effectively from breakage. Besides, if the crayon  30  is substituted by a color pencil, such color pencils can be free from sharpening.  
      As shown in  FIG. 1  and  FIG. 2 , the articulation method for said crayon cap  60  and penholder  10  in the current invention can be in this way: a ring-shaped groove  12  is set on the inner wall of the penholder  10  close to the exit of the crayon  30  and a positioning projection  62  is set on said crayon cap  60  at the location where it is inserted into the penholder  10  correspondingly, and said positioning projection  62  is inserted into said groove  12 .  
      The tip  21  of the watercolor pen  20  in the current invention is of fibers or cast part and the core  22  of said watercolor pen is made of strong absorbent materials with strong storage ability. Said watercolor pen  20  is also equipped with a cap  80  to protect the watercolor pen  20 .  
      The section of said penholder  10  accommodates said crayon  30  may design or use the other
