In an exemplary embodiment, the instrument  100  may include a writing tip  110  at one end of barrel  112 . The tip  110  may be a ball point, a pencil, a marker tip or other type of writing implement. In this embodiment, the instrument  100  includes a tool such as a light source  120  mounted to the barrel at the end opposite the writing tip. In other embodiments, the writing tip, the light source, or both, may be omitted from the tool  100 . 
     The touch tool  1  in this exemplary embodiment is a disc type touch tool, and includes a stylus disc  11  and a straight bar  12  connected with the center of the disc  11 . The disc  11  may be a plastic material. The straight bar  12  may include a flexible portion of a plastic material. 
     The upper ring  2  is a hollow cylinder structure, wherein its upper part forms a step  21  in which the cylinder can accommodate the disc  11  of the touch tool  1  in a retracted position ( FIG. 2 ). The upper ring  2  may be fabricated of ABS or other suitable material. The upper ring  2  with step  21  is supported on a rotating sleeve liner  6 , and symmetrical vertical guide grooves  22  are arranged in the lower cylindrical inner chamber of the upper ring. 
     A rotating wheel  3  ( FIG. 3 ) has an upper part, provided with a cylindrical hole  32  for accommodating the straight bar  12  of the touch tool  1 . The rotating wheel has an upper outer ring portion provided with guiding elements  31  matched with the guide grooves  22  of the upper ring  2 , and the lower part is provided with an inclined surface portion  33  corresponding to a deck structure  42  of the lower ring  4 . 
     The upper outer part of the lower ring  4  is provided with an annular spacing groove  41 . The inner chamber of the lower ring  4  is provided with a deck structure  42  corresponding to the incline surface portion  33 . The middle outer part of lower ring  4  is provided with a support ring or flange  43  which can be supported on the pen holder liner, and the lower outer part of the lower ring  4  is provided with threads  44 . 
     The lower part of the rotating sleeve liner  6  is provided with a projection  61  corresponding to the annual spacing groove  41 , and the projection  61  is spaced within the annular spacing groove  41 . 
     The rotating sleeve  8  is arranged between the outer step  21  of the upper ring  2  and support ring  43  of the lower ring  4 , and forms a tightening sleeve sheathed outside the rotating sleeve liner  6 . 
     Threads corresponding to the threads  44  of the lower ring are arranged inside the pen holder liner  5 , and the lower ring  4  is connected with the pen holder liner  5  through the threads. The outer part of the pen holder liner  5  is fixed to the inner chamber of the pen holder  7 . 
     The straight bar  12  of the touch tool  1  is connected with the cylindrical hole  32  of the rotating wheel  3  via threads, so that straight bar  12  can be readily assembled and disassembled. 
     The connection relationship between the upper ring  2 , the rotating wheel  3  and the lower ring  4  is shown in  FIGS. 1 and 2 , i.e. the upper ring  2  is sheathed outside the rotating wheel  3 , the guiding element  31  of the rotating wheel  3  is inserted into the guide groove  22  of the upper ring  2 , and the lower part of the rotating wheel  3  is inserted into the lower ring  4 . 
     A spring  9  ( FIG. 2 ) is also arranged between the inner surface of the step  21  of the upper ring  2  and the step  34  ( FIG. 3 ) of the rotating wheel  3 . The rotating wheel  3  is reset by the restoring force of the spring  9 , so that the touch tool  1  is retracted into the step  21  of the upper ring, as shown in  FIG. 1 . 
     After the touch tool  1 , the upper ring  2 , the spring  9 , the rotating wheel  4 , the rotating sleeve liner  6  and the rotating sleeve  8  are installed, the rotation of the rotating sleeve  8  relative to the pen body  7  can drive the rotating sleeve liner  6  and the rotating wheel  3  to rotate relative to body  7 . The rotating sleeve  8  and the rotating sleeve liner  6  are spaced by the annular spacing groove  41  of the lower ring  4  so that they cannot move up and down relative to the lower ring  4 , as shown in  FIG. 1 . When the incline surface  33  of the rotating wheel  3  butts against the deck  42  of the lower ring  4 , the rotating wheel  3  is spaced or constrained by its guiding element  31 , so that it cannot rotate and only can rise along the guide groove  22  of the upper ring  2 ; thereby, the touch tool  1  fixed to the rotating wheel  2  stretches or extends out of the upper ring  2 , and when it reaches the highest point of the disc  11 , the head of the surface  33  enters the groove  45  (formed in the lower ring  4 ) and is spaced as shown in  FIG. 4 , and the user can operate a touch sensitive surface of an intelligent device with the touch tool  1 . 
     After use, the user rotates the rotating sleeve  8  to drive the rotating wheel  3  to rotate, the incline surface  33  of the rotating wheel  3  surmounts the deck  42  and enter the space  46  of the lower ring  4 ; the incline surface  33  falls into the space  46  by the restoring force of the spring  9 , so that the entire rotating wheel is reset and the touch tool  1  is retracted into the step  21  of the upper ring. 
     Although the foregoing has been a description and illustration of specific embodiments of the invention, various modifications and changes thereto can be made by persons skilled in the art without departing from the scope and spirit of the invention.
