[0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the number of private cars has increased significantly to meet the needs of family travel, leading to traffic congestion and frequent vehicle collisions. Among these accidents, door deformation due to collisions or scratches is relatively common. Repairing deformed car doors typically involves welding washers to the damaged area using a mortise and tenon joint, followed by reshaping with a pull hammer. This method is effective for minor deformations. A search revealed a Chinese patent with authorization announcement number CN218692729U, which discloses a door reshaping tool that pushes from the inside out, assisting repair technicians in performing door reshaping operations more quickly and effectively. It mainly consists of a positioning screw, a top block, a bearing, a screw thrust flange, a screw handle, a screw, an internal threaded flange, adjusting shims, and a base plate. In use, the upper end of the screw is tightly fitted with the bearing, then combined with the internal threaded flange to form a helical pair, inserted into the bearing mounting hole of the top block, and the positioning bolt is tightened. Finally, the base plate is connected, assembling the reshaping tool. During repair, the shaping tool is placed inside the door, the top block is aligned with the deformed area, the base plate is fixed to the inner door panel, and the screw handle is turned. The screw pushes the top block outward to push the deformed area, assisting the repair technician in restoring the deformed area to its original shape. Its characteristics are: the screw and bearing are tightly fitted, the screw and the internal threaded tube flange form a helical pair, and the helical pair and the top block are movably connected through the bearing.
