Title: Removing tool for car-window edge strips

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a removing tool for car-window edge strips, particularly to one convenient to use, possible to use different tool sets changeable, and quickly removing edge strips in the outer side of a car window. 
   2. Description of the Prior Art 
   Generally a car window is provided with an edge strip closely contacting the glass of the car window for preventing water from directly flowing into the door and also scraping off water drops off the glass in case of the glass is lowered down. However, dirt and water may accumulate in the gap between the edge strip and the glass over time, resulting in erosion and breakup of the edge strip after a certain period of use. Therefore, the edge strip sometimes has to be replaced with new one. At present, no special tools for removing the car-window edge strip, and a flat tool such as a flat-tip screwdriver is usually used for removing it. As the edge strip is closely contacting the glass, a worker without a time-tested experience may not be dexterous enough to do the work and hurt in plying off edge strips or harm the metal portion of a window. Even if edge strips are pried off, there remains dried glue in the edge, necessary to be taken off by a knife, resulting in potential cut in a worker&#39;s fingers or hand. 
   SUMMARY OF THE INVENTION 
   The purpose of the invention is to offer a removing tool for car-window edge strips. 
   The main feature of the invention includes a grip, a linking rod, a protective disc and a tool set. The grip is provided with a recessed chamber, and a female threaded hole formed in a lower portion of the recessed chamber. The linking rod is combined on the grip and provided with a post member at a lower portion thereof, a male threaded rod formed at a lower end of the post member to engage with the female threaded hole of the grip, a flat insert groove formed diametrically in a substantive portion of the linking rod and opening to an upper end, at least one through hole bored in a side of a wall of the linking rod and communicating with the flat insert groove, at least one threaded hole formed in an opposite side of the wall of the linking rod and corresponding to the at least one through hole and communicating with the flat insert groove, and at least one screw respectively passing through the at least one through hole and further engaging with the at least one threaded hole.
