It should be noted that the fastening portion 213 is an extension rod, and the bending portion 222 is fastened to the fastening portion 213, that is, the extension rod is abutted to the inner wall of the mounting bracket 120 facing the bending portion 222 to form a fastening fit. After the oil tank cap is fixed a position through locating pin 230, articulated portion 212 rotates relative first pin joint, drives base member 211 and oil tank cap butt, and pole body 221 uses the second pin joint to rotate as the rotation center for kink 222 and joint portion 213 joint, and then obstruct base member 211 to keeping away from the motion of oil tank cap place direction, have guaranteed the spacing reliability of gag lever post 220 to locating lever 210.

The bent portion 222 is provided with a paddle 223. The lever body 221 is provided with the one-touch switch 223 mainly for facilitating the operation of the lever body 221 which is more convenient for the operator through the one-touch switch 223.

As shown in fig. 1 and fig. 3, the fixing bracket 110 is further provided with a positioning rack 111, a positioning column 112 is provided on the positioning rack 111, and the vehicle body is provided with a positioning groove matched with the positioning column 112. Set up reference column 112 and constant head tank and cooperate, through the radial positioning of constant head tank to reference column 112 to avoid fixed bolster 110 to take place relative motion along the relative automobile body of the direction of motion of automobile body, and then improve positioning fixture 1 and to the stability of fuel tank cap centre gripping, thereby guarantee that the fuel tank cap sprays paint evenly, improve the paint spraying quality of fuel tank cap.

Wherein the positioning frame 111 is provided with a lightening hole 113. The weight of the positioning frame 111 can be effectively reduced by arranging the lightening holes 113 on the positioning frame 111, and meanwhile, the production cost of the positioning frame 111 can also be reduced.

As shown in fig. 1 and 2, at least two spring pieces 116 are provided at intervals along the extending direction of the catching groove 115. Through setting up two at least spring pieces 116 along the extending direction interval of draw-in groove 115, compare in two spring piece 116 relative interval settings, can be favorable to improving the stability of fixed bolster 110 after on the automobile body through draw-in groove 115 joint more to ensure that the fuel tank cap that is located on installing support 120 can guarantee a stable state, it can not produce when guaranteeing to spray paint the fuel tank cap and greatly rocks the influence quality of spraying paint. According to the utility model discloses an embodiment, the draw-in groove 115 joint of fixed bolster 110 is on the door, and the quantity of spring leaf 116 is two, and is located the both sides of fixed bolster 110 respectively, and one of them spring leaf 116 welds on fixed bolster 110, and two spring leaves 116 set up along the extending direction interval of fixed slot.

And, at least two spring pieces 116 are detachably connected to the fixing bracket 110. The spring pieces 116 are detachably connected with the fixed support 110, the fixed support 110 is installed at different positions on the automobile body by replacing the spring pieces 116 with different sizes or materials, so that the adaptation range of the fixed support 110 is increased, meanwhile, the elasticity of the spring pieces 116 is guaranteed by replacing the spring pieces 116, and the stability of the fixed support 110 fixed on the automobile body is further guaranteed.
