[0042] like Figures 2 to 4 As an embodiment of the utility model, it also includes a support frame, which is connected to the support column 31. Further, the support frame at least includes a first support frame 32 and a second support frame 33, both of which are connected to the support column 31 and are staggered along the height direction of the support column 31; the first support frame 32 is symmetrically arranged with respect to the support column 31, and the second support frame 33 is also symmetrically arranged with respect to the support column 31.

[0043] The utility model utilizes the first support frame 32 and the second support frame 33 to simultaneously connect with two different fenders 5, so that the same fender 5 has multiple connection positions, which can share the supporting force and improve the connection reliability. The support frame includes but is not limited to the first support frame 32 and the second support frame 33, and more support frames can be set to improve the connection reliability with the fender 5. Different support frames are welded with the support column 31 after being connected. Since the first support frame 32 and the second support frame 33 are both axisymmetric structures, when both sides of the first support frame 32 and both sides of the second support frame 33 are connected and fixed with two fenders 5, the center of gravity can still fall on the support column, ensuring that the center of mass of the fender and the fixing center of the support device and the frame are in the same plane perpendicular to the ground, reducing the additional torque, so as to improve the reliability of the support device during the use of the fender 5. By setting the support column at the end of the first support frame 32 and the second support frame 33, it is possible to avoid interference with the leaf spring suspension.

[0044] As an embodiment of the present invention, the first support frame 32 and the second support frame 33 completely overlap in the projection direction.

[0052] Example 2

[0053] like Figure 5 and Figure 6 The second embodiment of a fender support device of the utility model is shown. This embodiment is similar to the first embodiment, except that the first support frame 32 and the second support frame 33 are arranged in a mirror image.

[0054] The first support frame 32 and the second support frame 33 that are arranged in a mirror image, and the first support frame 32 and the second support frame 33 that are arranged in the same direction, can both achieve better connection and support effects.

[0055] The first support frame 32 is composed of a support plate 321 in the middle and connecting plates 322 symmetrically arranged on both sides. The support column 31 is arranged through the end of the support plate 321 and welded to the support plate 321. The connecting plate 322 is provided with a plurality of mounting holes 4.
