Title: Reading device for a tool

Description:
FIELD OF THE INVENTION  
       [0001] The present invention relates to a reading device for a torque tool and the device includes multiple reading windows and each mark is embedded under a surface of the handle of the tool.  
       BACKGROUND OF THE INVENTION  
       [0002] A conventional reading device for a torque tool is shown in FIG. 1 and generally includes a plurality of marks  30  which is located on the outer surface of the handle  3  of the tool and a reading window  2  is connected to the shank  1  of the tool. The handle  3  is rotatable so as to align one of the marks  30  with the index arrow. The reading window  2  allows the user to read the data of the output torque of the tool. As illustrated in the enlarged drawing, the marks are printed (or by any known method) on the outer surface of the handle  3  so that they are easily to be worn off. Besides, the number of the reading window  2  is only one and the position of the reading window  2  cannot be changed. The position of the reading window  2  could not be convenient for reading especially when the tool is used in a narrow space.  
       [0003] The present invention intends to provide a reading device for a tool wherein the number of the reading windows is multiple and the marks are embedded in the outer surface of the handle so that they are not worn off.  
       SUMMARY OF THE INVENTION  
       [0004] In accordance with one aspect of the present invention, there is provided a reading device for torque tool which includes a handle, a shank extending from the handle, and a function end. The reading device comprises a plurality of reading windows connected to the shank of the tool and a plurality of marks are located on an outer surface of the handle.  
       [0005] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0011] Referring to FIGS. 2 and 3, the reading device for a torque tool  10  of the present invention comprises a plurality of marks located on an outer surface of the handle  20  and each mark is composed of a notch  21  defined in the outer surface of the handle  20  and each notch  21  has a mark piece  22  received therein. The mark piece  21  is located below the outer surface of the handle  20  so that the mark piece  21  is not worn during using the torque tool. A window  30  is connected to the shank of the tool  10  and shows the torque that the tool outputs.  
     [0012]FIG. 4 shows that the number of the reading windows  30  is multiple and the positions of the reading windows  30  can be set to meet the needs of the way of use of the tool  30 . The positions of the reading windows  30  can be arranged as shown in FIG. 5 and the reading windows  30  can also be arranged at different horizontal planes such that the users read the data conveniently even if the tool is used in a deep or narrow space.  
     [0013] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
