[0002] The clamping device for car grille paint spraying is a tool or equipment designed specifically for car grilles to ensure uniformity and quality of spraying. During the spraying process, the grille needs to be fixed in a stable position to prevent it from moving or shaking, thereby avoiding uneven paint spraying or defects.

[0003] Chinese patent publication number CN209156195U discloses a clamping device for spraying automotive parts, including a No. 2 support leg, which is connected to one end of a first electric telescopic rod through a No. 2 hinge. The end of the first electric telescopic rod away from the No. 2 hinge is connected to a slider through a No. 3 hinge. The slider is arranged in a slide rail. The first electric telescopic rod can be shortened by an external switch to place the carrier plate to a nearly horizontal position. During this process, the length of the first electric telescopic rod is shortened, causing the slider to slide toward the support in the slide rail. Since the distance between the No. 1 hinge and the No. 2 hinge remains unchanged, the inclination slope of the carrier plate will decrease. This design allows the user to very conveniently adjust the inclination angle of the carrier plate.

[0004] The automobile parts spraying clamping device of the above patent needs to be clamped from the outside of the automobile parts during the clamping process. Clamping from the outside of the automobile parts will affect the spraying at the clamping position and affect the effect of a single spraying. Utility Model Content
