Bolt 6 2 (nut), lacks the convenience of assembly, and because the seat cover 6 is clamped on the handle 9 of the bicycle with a rigid structure, it is easy to form a wear part of the jacket - for tens of thousands of dollars For high-priced bicycle owners, „ does not want to use this kind of easy to damage the body after the mirror junction At the same time, the flexible tube 3 0 3 itself cannot withstand the large vibration when the bicycle is running, and it is easy to have the rear view mirror body 3 0 2 displacement or drooping, and it is difficult to perform the normal rear view function. [0003] The bicycle rear view mirror structure shown in FIG. 2 is provided with a vertically protruding shaft (not shown) on the outer side of an open curved sheet-shaped seat cover 10, for inserting a combination. A form number A0101 is formed in the piece 1 0 1 and a M369278 is pivoted. The joint member 1 Ο 1 can be pivotally connected to the rear view mirror body 3 via a horizontal pivot 3 Ο 1 . The mirror body 30 is formed with a pivoting structure having two degrees of freedom with the seat cover 10, and the seat cover 10 is provided with a side recess 1 0 2 on one side of the opening. A buckle 1 〇 3 is arranged on the other side of the opening, and an elastic band 20 of telescopic bending elasticity is provided, and a 镂-shaped hollow groove 20 2 is provided on one end side thereof, and the other end side is provided on the other end side. The buttonhole group consisting of a plurality of buttonholes 2 0 1 ; as shown in Figures 3 and 4, it can be seen that the assembly is carried out by an elastic band 2 0. 2 sets are engaged with the side recesses 1 0 2, and the seat cover 10 is attached to the handle 90 of the bicycle, and the elastic band 2 is appropriately stretched to be sleeved on the handle 90, and the other end is The buttonhole of the side of the buttonhole group 2 Ο 1 is sleeved in the buckle 1 to form a positioning, so that the seat cover 10 (the mirror body 30) can be fixed to the handle 90, The elastic band of the soft (rubber) material is used, and the seat cover of the plastic material is clamped to the 90 side of the handle 90, so that the surface of the handle 90 can be effectively prevented from being broken, and the rear view mirror body 30 is coupled by the member. 1 0 1 is short-distance and tightly combined with the seat cover 10, which can effectively slow down the displacement or drooping of the rear view mirror body due to vibration.

Since the distance between the rear view mirror body 30 and the seat cover 10 is extremely short, even if the seat cover 10 is positioned on the side of the handle 90, it is still easy for the rider to The hand is blocked, which affects the overall rear view effect. [0005] 2. Since the joint stability between the seat cover 1 〇 and the handle 90 is ensured, the elastic band 20 must be strongly stretched (to have the maximum binding elasticity) when assembled, so It is easy to have the 镂-shaped hollow groove 20 Form No. Α0101 Page 4 of 22 M369278 2 Deformation expands and detaches from the undercut 1 Ο 2 (or cannot be stably embedded in the undercut 102, as shown in Fig. 5), resulting in Poor combination strength or even loosening occurs. [〇〇〇6] 3. Since the elastic band 20 is an elastically deformable material, it must be stretched hard during assembly, so that the button holes of the buttonhole group 2 Ο 1 are also prone to expansion deformation. Therefore, the single hook 1 0 3 is combined with any button hole, and it is easy to cause looseness.
