Turbulent flow inner plate pre-tightening tool

The utility model discloses a pre-tightening tool for a spoiler inner plate, and relates to the technical field of automobile parts. Comprising a fixed clamp arm with a hollow structure, a first pressing plate arranged at the front end of the fixed clamp arm and perpendicular to the fixed clamp arm, a limiting knob screwed to the rear end of the fixed clamp arm, a movable clamp rotationally connected with the fixed clamp arm, a second pressing plate arranged at the front end of the movable clamp and matched with the first pressing plate, and a pressing handle connected with the lower portion of the movable clamp. The two ends of the connecting rod are connected with the front portion of the pressing handle and the front end of the limiting rotary knob respectively, and the two ends of the reset spring are connected with the fixed clamp arm and the movable clamp respectively. Compared with an existing manual pressing mode, the risk that the turbulent flow inner plate is crushed due to personnel factors is redu
