After assembly, the two can be completely fitted together to form an "inverted buckle" to prevent the assembled support tube 3 from sliding out of the inner hole of the support 1; the outer wall of the mounting frame 4 It is provided with evenly distributed connecting holes 19. When in use, multiple bolts are respectively inserted into the multiple connecting holes 19 so that the fender of the car is bolted to the mounting frame 4. One side outer wall of the support 1 is provided with evenly distributed mounting holes 7. The bolts are inserted into the mounting holes 7 so that the support 1 is fixed to the frame of the car by bolts. The outer wall of the support 1 is integrally formed with evenly distributed reinforcing ribs 8. The reinforcing ribs 8 on the side wall of the support 1 are used to improve its strength in the up and down and front and back directions of the whole vehicle and improve the support 1's ability to resist extreme bursting. A slider 18 is fixed to the inner wall of the pipe fitting 13, and a slide groove 17 is provided on the outer wall of the support column 14. The slider 18 slides inside the slide groove 17, and the slider 18 cooperates with the slide groove 17 to prevent the support column 14 and the pipe fitting 13 from rotating.

[0027] Working principle: When the fender bracket needs to be assembled, first insert the pipe fitting 12 into the conical cavity 9 of the support 1, and press the rubber bushing 2 into the conical cavity 9, so that the positioning boss 5 cooperates with the positioning groove 6 on the inner wall of the conical cavity 9, and the non-return tooth boss 10 cooperates with the non-return groove 11 on the inner wall of the conical cavity 9, then sleeve the pipe fitting 2 13 on the outside of the screw 15, and make the part of the support column 14 exposed from the pipe fitting 12 inserted into the inside of the pipe fitting 2 13, and match the slider 18 on the inner wall of the pipe fitting 2 13 with the slide groove 17 on the outer wall of the support column 14, and then insert the sealing plug 16 into the pipe fitting 2 13. After that, it is threadedly connected with the screw rod 15 to complete the assembly between the fenders; when in use, the bolt is inserted into the mounting hole 7, so that the support 1 and the frame of the car are fixed by the bolt, and then multiple bolts are respectively inserted into multiple connecting holes 19 to fix the fender of the car to the mounting frame 4; when the fender of the car needs to be replaced, the sealing plug 16 is threadedly separated from the screw rod 15, and then the pipe fitting 13 is removed from the screw rod 15, so that the mounting frame 4 and the fender can be disassembled more conveniently as a whole, without removing multiple bolts between the fender and the mounting frame 4 one by one, making the replacement of the fender more convenient.
