Description

Technical Field

[0001] The present invention relates to the field of automobile maintenance auxiliary equipment, in particular to an automobile maintenance auxiliary device. Background Art

[0002] Automobile maintenance is a general term for automobile care and repair. It involves using technical means to troubleshoot faulty automobiles, identify the causes of the faults, and take certain measures to eliminate the faults and restore the vehicle to a certain performance and safety standard. Automobile maintenance includes major overhaul and minor overhaul. Major overhaul refers to restorative repairs that repair or replace any parts of the automobile to restore the vehicle to its original technical condition and restore its lifespan. Minor overhaul refers to operational repairs that replace or repair individual parts to ensure or restore the vehicle's working ability. After a car is hit or struck by a heavy object, a dent will appear on the car plate. A sheet metal repair pulling tool is a tool used to repair a car. It is mainly used to repair sheet metal dents caused by general car collisions, scratches, etc. However, the suction cup in the prior art is generally a plane, so it cannot fit well with the dent in the car during use, and the suction cup moves with the same amplitude, which may cause the shallower dent at the edge to be pulled too much and bulge out. Subsequently, the bulging part needs to be squeezed inwards back into place, which is troublesome. It is necessary to design an automobile repair auxiliary device that can assist in returning the dent to the original position. This is the shortcoming of the prior art. Summary of the invention

The swing of the T-shaped rod drives the swing of the straight groove rod. According to the limiting effect of the straight groove rod on the square rod, the different movement amplitudes of the square rods at different positions are realized. The closer the square rod is to the telescopic rod of the electric push rod, the larger the movement amplitude is. The sunken part of the automobile plate is more deeply sunken in the center. In this case, the larger the movement amplitude of the square rod is, the larger the square rod is. The square rod is radiated outward along the telescopic rod of the electric push rod as the center. The movement amplitude of the square rod decreases successively, which can match the situation that the sunken amplitude of the automobile plate decreases from the center to the periphery, so as to facilitate recovery.

The position and angle of the top block are easy to adjust, which can play an auxiliary fixing role for the device. When in use, the person controls the top block to firmly support the car, so that the telescopic rod of the electric push rod can be retracted to apply pulling force to the car.
