The top cover 21 has a "surface 212" and a pressing surface 213 opposite to the joint surface 212. In the present embodiment, the roof surface 213 is an 8 arc-shaped concave surface formed on the top cover. The cover 21 includes a cover portion 23 The basic rectangular rectangular receiving frame 215 is filled/valley; the receiving frame 215 is inside. The bottom cover 25 is substantially circular, wherein 邙=:::r corresponds to one. TM: can be replaced with i wear resistance respectively The top cover 21, the filling portion 23 and the bottom cover 25 are made of the same material. In the embodiment, the bottom cover 25 and the plastic material of the plastic cover are made of plastic, and the top cover 21 is formed by wear resistance. The top cover 21 and the filling portion of the bottom cover 25 are formed by two-color universal body molding. 『二参2 Read Fig. 2 to Fig. 4, the fixing bracket 3〇 includes two supporting portions 31, and one end is provided by one The connecting portion 34 and the four elastic portions 35. The elastic portion 35 of the supporting portion 31 of each connecting portion 34 is connected to the second reading portion (4) such that the two-shaped portion j, the connecting portion 34 and the four elastic portions 35 together form a substantially moment The elastic portion 35 is substantially of a type 2 such that the two connecting portions 34 are convexly fixed to the plane where the 呷=°Ρ31 is located. The fixing portion 32 is disposed at the middle of the frame. The opposite sides of the pair 32 are respectively fixedly connected to the middle of the two connecting portions 34. The through hole 321 is formed in the middle portion of the second portion. The present embodiment * Λ 胜. The middle portion, the first fixing member 40 and the second fixing member 5 The fixing member 40 has the same shape as the fixing portion 32 of the fixing bracket 30. The fixing member 50 has the same shape as the supporting portion 31 of the fixing bracket 30. The housing is provided with a receiving hole 1〇. 2. The top cover 21 of the button cap 20 can be [0012] [0014] sliding in the receiving hole 102 099129173 Form 鹄鱿Α〇 1 〇! Page 5 / Total 15 page 0992051189-0 201209870 [0015] Referring to FIG. 1 , FIG. 2 and FIG. 5 , when the button structure 103 is assembled, the first fixing member 40 is first adhered to the fixing portion 32 of the fixing bracket 30 near the surface of the supporting portion 31.
