Inside the hole. By the above-mentioned technical means, the creation and the steering tube are mutually forcedly fastened by the interference fit before the creation, so that it is not necessary to manufacture the same for the relatively fixed knot, such as thread. Moreover, it is also possible to utilize a large and rapid assembly of machine equipment to effectively achieve an increase in production efficiency. [Embodiment] Referring to the first figure, the front fork and steering tube coupling device includes a front fork (10) and a Steering tube (20), wherein: Referring further to Figures 2 and 3, the front (10) is made of a magnesium alloy material, which includes a shoulder (11) and two outer tubes (12), the shoulder The two opposite sides of the portion (11) are a bottom side and a top side, and an assembly hole (13) is formed between the bottom side and the top side, and the two outer tubes (12) are respectively disposed on the shoulders ( 11) opposite ends, and bent toward the bottom side of the shoulder (11); 3 its diameter is not steering tube (20) is made of aluminum alloy or magnesium alloy material M345765 larger than the front and (10) assembly hole (13) an aperture, one end of the steering tube (20) is provided An assembly portion (21) having a diameter larger than an aperture of the assembly hole (13) of the front fork (1), and a stop portion (22) formed at a free end of the assembly portion (21) . For the cooperation, as shown in Figures 3 and 4, when the steering tube (2〇) is to be mounted on the uranium fork (10), the steering tube (2〇) is made of the front (丨〇) shoulder ( u) 'The bottom side of the tooth is placed into its assembly hole (1 3 ), and protrudes from the top side of the front (1 〇) shoulder (1 ^). Then the steering tube (20) is applied The thrust force is such that the diameter of the assembly portion (21) is larger than the diameter of the assembly hole (13) of the front fork (10), so that the assembly portion (21) can be tightly fixed to the front fork by interference fit (1)组装) in the assembly hole (13), and the stop portion (22) is supported on the bottom side of the front (1〇) shoulder (ii) to make the front fork (1〇) and the steering tube (20) Can be assembled relative to the positioning. As described above, with the design of the present invention, the front fork (1 〇) and the steering tube (2 〇) are manufactured without additional processing for relatively fixed structures, such as threads, and can also utilize a large number of machines and fast Assembled, effectively achieving the goal of increasing production efficiency.
