Problems solved by technology

[0002] With the continuous development of modern society, more and more cars have entered our lives, almost becoming a necessity in people's lives. More and more people own private cars, but it also brings many problems. After the plate is made, after the collision, the sheet metal is easy to dent and form dents, but will not automatically recover. After the dents appear on the sheet metal, the replacement cost is high, the time is long, and it is prone to mismatching, so generally choose repair
[0003] Since the surface of the scar formed after the car is collided is irregular, the position and size after the collision are also different, which requires certain requirements for the installation position, and the existing bridge-type car dent repair tool cannot adjust the distance between the two legs. distance, it is very inconvenient to use, and tools of different sizes need to be selected according to the different positions of the depressions. It is very troublesome to load and unload, time-consuming and laborious, and when repairing the depression, the two legs are supported on both sides of the depression of the car, and the legs will cause damage to the car. The sheet metal on both sides produces a certain force to cause the sheet metal on both sides of the car to dent, resulting in the need for multiple trimming of the sheet metal, which wastes a lot of manpower, material resources and time. Another car dent repair tool uses a welding machine. The front end of the elongated welding needle touches the concave position of the car, and a large current is passed through instantly to spot weld the elongated welding needle on the concave position of the car. The impact drives the long welding needle to move, so that the long welding needle pulls up the concave position. This method of trimming the automobile sheet metal is easy to operate, and it is not easy to damage the surface of the automobile. Therefore, it is widely used by technicians in the automobile repair industry. However, there are still some problems in this method. The impact force of the hand hammer is not easy to control. Excessive force may cause the concave sheet metal to be pulled up excessively to form a convex hull.

Abstract

The invention discloses an automobile sag repairing tool. The automobile sag repairing tool comprises a pulling force part and a pair of adsorption chains; each adsorption chain is formed in the modethat at least four rectangular hinge blocks are hinged to one another, and the bottoms of the side faces, in the same direction, of the opposite faces of the rectangular hinge blocks are provided withhinge points used for allowing the adjacent rectangular hinge blocks to be hinged; hooks are arranged on the rectangular hinge blocks located at the corresponding ends of the sides, far away from thehinge points, of the adsorption chains; and the rectangular hinge blocks are provided with T-shaped fixing rods in a penetrating mode in the width direction, and suction cups are arranged at the ends, close to the hinge points, of the T-shaped fixing rods. According to the automobile sag repairing tool, in the repairing process, a pair of the adsorption chains are symmetrically adsorbed to the two sides of an automobile sag, a rotating handle is rotated to enable a rotating shaft to wind a first connecting rope and a second connecting rope, the first connecting rope and the second connectingrope pull the adsorption chains to rotate to repair the sag, no supporting point is needed in the repairing process, the condition that in the repairing process, counter-acting force is generated to act on an automobile to generate an adverse effect is avoided, labor is saved, operation is easy, and the automobile sag repairing tool is suitable for a green hand.
