## Background
BACKGROUND OF THE INVENTION
a) Field of the Invention
The present invention relates to a repairing kit for automotive dents, and more particularly to a repairing kit that can be used to completely repair auto body cavities by a DIY (Do It Yourself) method.
b) Description of the Prior Art
Dents are created on a general automobile when the automobile is hit by small rocks or foreign objects. An owner of the car cannot repair by to a DIY method, and has to rely on an auto repair shop to repair the dents. Nevertheless, the majority of repair procedures taken by the auto repair shop include first hammering out the automotive dent cavity to restore it to a smooth surface, and then implementing a baking finish on the surface of the car body, which is both time consuming and very troublesome.
There are a few USA patents that mention a repairing kit for automotive dents, including U.S. Pat. Nos. 1,457,570, 169,646, 5,203,196 and 5,934,139. Nevertheless, all the abovementioned patents are different from the present invention.

a pull seat 40, a threaded hole 41 in a center of the pull seat 40 providing for locking with the pole 22 of the draw bar 20, with that a bottom of the pull seat 40 is provided with a T-shaped slot 42;
a pull piece 50, the pull piece 50 being in a shape of a letter 1, with that the pull piece 50 can be a structure of all kinds of shapes and sizes, and a neck member 51 of the pull piece 50 is emplaced and fixed in the T-shaped slot 42 of the pull seat 40;
a grab bar 60, the grab bar 60 being emplaced in the hollowed-out member 13 of the body 10 from a side of the body 10, with that a shaft A penetrates a through-hole 61 at a front section of the grab bar 60 and is then locked in the shaft hole 14 of the body 10, a long hole 62 at a middle section of the grab bar 60 is penetrated by the draw bar 20 and the long hole 62 is abutted at the sleeve 23 of the draw bar 20 (as shown in FIG. 3);
a handle 70, an end of the handle 70 being provided with a screw 71, with that the screw 71 is locked in the bolt hole 15 of the body 10;
two foot stands 80, the foot stands 80 being installed at a bottom of the body 10 in a bilaterally symmetric way, and an end of the foot stand 80 being provided with a circular base 81, with that the circular base 81 is emplaced in the arc-shaped slot 16 of the body 10, the screw bolt 171 penetrates a through-hole 811 in a center of the circular base 81 and is then locked and positioned in the threaded hole 17, an interior of the circular base 81 is provided with a few locating holes 812 surrounding the through-hole 811, the locating holes 812 provide for latching selectively with the beads 183 for positioning, and a bottom of the foot stand 80 is provided with another through-hole 82; and
