Because of the screw, the shoulder has a shoulder sleeve hole. Slightly larger retaining edge, so after the upper tube is locked, I borrow the screw to prevent the upper tube from being removed. Because of the need to process the screw in the upper mouth of the upper eye, the screw is screwed to the thread. The caps on the section must also be made of metal to resist the support, so it does not meet the economic benefits and processing costs. - In view of this, the creator has been engaged in the production, marketing, and reading of the bicycle fork for many years, and has been concerned with the lack of relevant structures in the current structure, and after the improvement and testing of the two sides, the people have finally created A bicycle structural improvement in front of the upper tube and the shoulder seat. [New Content] The main purpose of this creation is to provide a simple and firm structure improvement of the front and upper shoulders of the bicycle. In order to achieve the above purpose, the front of the bicycle is provided with the M324026 B /, and the structural improvement of the shoulder seat is mainly carried out on the sides of the shoulder seat for the upper fork tube. The outer flaring is formed at the convex end of the diameter, and the two front forks are arranged in a small section of the small-diameter class-like nozzle, which can be abutted by the white-level official password. Living under the convex shoulder, and extending beyond the convex f port, the graded tube mouth is formed into a flared shape and the mouth is expanded outside the sleeve hole, thereby making the front fork upper tube and shoulder The seat can be combined with a simple and firm fixture. II. Into-step--understand the characteristics of this creation, the technical means and the expected effect. I will use this method of creation to confuse it. I believe that we can have a deeper and more specific understanding of this creation, as follows: [Embodiment] First, refer to the first and second figures, which are the three-dimensional exploded schematic diagram of the creation and the schematic diagram of the anatomical surface. It can be seen that the creation is mainly in the shoulder seat! 〇 供 供 供 供 〇 〇 〇 〇 〇 〇 〇 〇 〇 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工 工The extraoral line is set to a small section of the smaller diameter of the class-like nozzle 2丄, just by the class-like nozzle 2 1 so that the upper tube 2 〇 can resist the convex wi 〇τ, and will protrude from the convex end 1 1 The extra-class tubular nozzle 2丄 is formed into an outwardly expanded shape and is tightly engaged with the outer flare 1 1 1 on the sleeve 1 1 and then placed in a class-like nozzle 2 1 a which is formed into a flared shape. The dust jacket 3 (as shown in the first figure) 〇, and by the composition of the above components, please continue to refer to the third figure, which is composed of the front fork upper tube 2〇 and the shoulder seat.

N In summary, the improved structure of the bicycle front fork upper tube and the shoulder seat is fixed, so that the upper fork upper tube and the shoulder seat can be extremely simple and firmly combined and fixed. Progressive practicability, and at the same time, the domestic technical information on such structures is not found in the literature. The same structure is not found in the literature. Therefore, this creation already has new patent requirements, and the law applies. However, the above-mentioned ones are only one of the preferred embodiments of the present invention, and therefore, the equivalent structural changes that are applied to the scope of the present application and the scope of the patent application are included in the scope of the patent. > [Simple description of the schema] The first diagram is a three-dimensional decomposition diagram of the creation.
