     BACKGROUND 
     1. Technical Field 
     This disclosure relates to a stylus for portable electronic devices. 
     2. Description of Related Art 
     Styluses are often used with touch screens of electronic devices. A stylus may include a main body and a nib portion formed at one end of the main body, and be configured for comfortably held and used by an average user. However, the typical pen-like configuration is often difficult for certain types of users to accurately use, such as users with vision deficiencies. 
     Therefore, there is room for improvement within the art. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Many aspects of the stylus can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the multifunctional case. 
         FIG. 1  is an integral assembled schematic view of a stylus according to an exemplary embodiment. 
         FIG. 2  is an exploded schematic view of the stylus shown in  FIG. 1 . 
         FIG. 3  is similar to  FIG. 2 , but viewed from a different angle. 
         FIG. 4  is a schematic view of the stylus shown in  FIG. 1  in use. 
     
    
    
     DETAILED DESCRIPTION 
       FIG. 1  shows an exemplary stylus  100  for a touch screen of a portable electronic device. The stylus  100  includes a bar portion  10 , a nib portion  13  formed at an end of the bar portion  10 , and a lens member  15  rotatably assembled on the nib portion  13 . 
     Referring to  FIGS. 2 and 3 , the bar portion  10  includes a main section  101  and a connecting section  102  formed at an end of the main section  101 . The main section  101  functions as a grip for users. The connecting section  102  tapers to transitionally connect the main section  101  to the nib portion  13 . 
     The nib portion  13  includes a nib section  132  and a connecting seat  134  firmly positioned on the nib section  132 . The nib section  132  integrally connects to and extends along the connecting section  102 , and the nib section  132  has a nib end  135  for touching the screen of the electronic device. The connecting seat  134  is used to rotatably connect the lens member  15  to the bar portion  10 . The connecting seat  134  is sleeve shaped and perpendicularly positioned on the nib section  132  to form a first connecting end  1341  and an opposite second connecting end  1342 . Understandably, the connecting seat  134  can be integrally formed with the nib section  132  by injection molding, or can be a simple unit detachably assembled with the nib section  132 . In the exemplary embodiment, the connecting seat  134  is integrally formed with the nib section  132 . The connecting seat  134  has a central hole  1343  extending along an axis O-O and running through the first connecting end  1341  and the second connecting end  1342 . A latching rib  137  is axially formed on the exterior surface of second connecting end  1342  to engage with the lens member  15 . 
     The lens member  15  includes a lens portion  150  and a connecting portion  153  set at a side of the lens portion  150 . The lens portion  150  is generally a semi circular shaped lens, and the lens portion  150  can be a concave lens and acts as a magnifying lens for the user when viewing through it. The connecting portion  153  made of elastic materials and includes a first connecting unit  155  and a second connecting unit  157  arranged oppositely with the first connecting unit  155  to form a clamp space  159 . The first connecting unit  155  include a clamp plate  1551  and a protrusion post  1552  formed on the clamp plate  1551 . The protrusion post  1552  has the same diameter as the central hole  1343  and can engage in the central hole  1343 . The second connecting unit  157  can be an annular member and has a hinge hole  1570 . The hinge hole  1570  has the same diameter as the connecting seat  134 , and allows the connecting seat  134  to pass through. The second connecting unit  157  defines a plurality of axially parallel latching recesses  1575  in the inner circumference surface. The latching recesses  1575  can latch to the latching rib  137 . The clamp space  159  is configured to receive the connecting seat  134 . 
     Referring to  FIG. 4 , to assemble the lens member  15  into the connecting seat  134 , the first connecting unit  155  is deviated by an outer force to enlarge the clamp space  159 . The first connecting end  1341  is inserted into the hinge hole  1570 , and the latching rib  137  engages in one of the latching recesses  1575 . Then, the outer force is released, and the first connecting unit  155  returns to original position and the protrusion post  1552  engages in the central hole  1343 . Thus, the lens member  15  is assembled with the connecting seat  134 . The stylus  100  is substantially assembled. 
     In use of the stylus  100 , the lens member  15  can be adjusted and rotated to an optimum angle for viewing. The latching rib  137  slides from one of the latching recesses  1575  into another latching recess  1575 . After rotating a predetermined angle, the latching rib  137  is latched with one of the latching recesses  1575 , and the lens member  15  is secured relative to the nib portion  13 . The user can view magnified images on the screen through the magnifying lens member  15 , the magnified view aiding in more accurate touching of the touch screen with the stylus  100 . 
     It is to be understood that, the connecting seat  134  can be fabricated separately, and the connecting seat  134  can be made of elastic material such as thermo plastic urethane (TPU). The connecting seat  134  defines a radial engaging hole (not shown) to receive a through passing of the nib section  132 , securing the connecting seat  134  on the nib section  132 . Thus, the nib portion  13  may include only the nib section  132 , and the lens member  15  can further include the connecting seat  134 . In assembly, the connecting seat  134  is assembled to the connecting portion  153 , and then the connecting seat  134  is engaged with the nib section  132 . 
     It is to be understood that even though numerous characteristics and advantages of the present exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
