When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 6 together, the cantilever according to the present invention will now be described. The outrigger includes: a base 1, a first tube 21, a second tube 22 and a third tube 23; the base 1, the first pipe body 21, the second pipe body 22 and the third pipe body 23 are fixedly connected in sequence; the thickness of the first tube 21 is greater than that of the third tube 23; and the first pipe 21 is smoothly connected with the outer surface of the third pipe 23 through the second pipe 22, and the first pipe 21 is smoothly connected with the inner surface of the third pipe 23 through the second pipe 22.

Thus, the base 1 can be fixed on the frame body 31 (frame body 31: such as a vehicle beam), the object 32 to be installed (object 32 to be installed: such as a fender) can be fixed on the second pipe 22 (and/or the object 32 to be installed is fixed on the third pipe 23), the third pipe 23 transmits the received external force to the first pipe 21 through the second pipe 22 in sequence, and the first pipe 21 transmits the external force to the frame body 31 through the base 1; the first pipe body 21 has stronger bending resistance and is not easy to bend because the thickness of the first pipe body is larger than that of the third pipe body 23; the outer surfaces of the first tube 21, the second tube 22 and the third tube 23 are smoothly connected, and objects are not easy to scratch along the first tube 21 through the second tube 22 and the third tube 23; the inner surfaces of the first, second, and

third pipe bodies

21, 22, and 23 are smoothly connected, that is, the thickness from the first pipe body 21 to the third pipe body 23 is gradually reduced, so that the stress transfer between the first pipe body 21 and the third pipe body 23 through the second pipe body 22 is more gradual.

Optionally, in an embodiment, the base 1 is provided with an opening 11, and the first tube 21 is inserted into the opening 11; therefore, the first tube 21 is tightly contacted with the base 1, and the first tube 21 is not easy to loosen from the base 1.

Optionally, in an embodiment, in the extending direction of the first tube 21 to the second tube 22, the outer surface of the base 1 gradually approaches the first tube 21; thus, when the stress is transmitted from the second tube 22 to the base 1 through the first tube 21, the stress is transmitted to the portion of the base 1 with a thinner thickness from the first tube 21, and the thinner base 1 is beneficial to deformation and stress release. Alternatively, in one embodiment, the porthole 11 extends in a straight direction. Thus, the processing is easy, and the first pipe 21 is easily inserted into the duct 11 and connected to the base 1.

Optionally, in one embodiment, the base 1 has a recess 12 thereon; thus, the stress is released conveniently through the concave part 12 when the base 1 is subjected to an external force. Optionally, in one embodiment, the recess 12 is plural, and the plural recesses 12 are disposed around the first tube 21; in this way, the stress transmitted from the first pipe 21 to the base 1 can be released by the recessed portions 12 formed around the outside of the first pipe 21. Optionally, in one embodiment, the recess 12 is elongated; in this way, the stress is easily released along the extending direction of the recessed portion 12. Optionally, in one embodiment, the recess 12 is a rounded rectangle; thus, the corner deformation of the depressed portion 12 is not easily broken.

Optionally, in an embodiment, the first tube 21 is provided with a first fastening member 41, the third tube 23 is provided with a second fastening member 42, and the object 32 to be mounted is detachably fixed on the first tube 21 and the third tube 23 by the first fastening member 41 and the second fastening member 42.
