The invention aims to provide an auxiliary paint spraying device for a front cover of a sedan, which can lighten the labor intensity of operators and prevent the paint on the inner surface of the front cover from being bumped so as to improve the production efficiency and paint spraying quality and reduce the production cost. The device comprises a main rod, the front end of the main rod is provided with a fixed part matched with a circular hole at the rear end of the front cover of the sedan, the rear part of the main rod is provided with a handle extending backwards, and the rear end of the main rod is downwards bent to form a support part. During use, the auxiliary paint spraying device for the front cover of the sedan can be fixed with the front cover of the body, and then the front cover of the body is easily lifted by using the handle to spray paint; and after the paint spraying is finished, the front cover of the body is suspended above a front bumper beam of the sedan by using the support part of the auxiliary paint spraying device for the front cover of the sedan so as to avoid paint bumping caused by the contact between the inner surface of the front cover of the body and the front bumper beam. The auxiliary paint spraying device for the front cover of the sedan has the advantages of greatly reducing the labor intensity of workers, improving the production efficiency and paint spraying quality, saving the production cost, along with simple structure and convenient operation.
