The top edge of the second core board 102b has an extended structure 〇 2e. In the prior art, the positioning tabs 06a are typically bolted to the extensions 10 2 e of the second housing panel 2b. 200924611 In order to achieve the purpose of disassembling the expansion board 1 〇6 without any use of hands (without tools), an expansion board fixture 120 (shown in Figure 2) is added to the computer system. The user only needs to apply the wrench portion 126 of the expansion board fixing member 12〇 to fix the positioning piece 〇6a to the extension structure 102e of the second casing plate 丨〇2b without any additional tools. Before the extension piece fixing member 120 is used to fix the positioning piece 106a to the extending structure 102e of the pupil of the second casing plate 1, the opening of the positioning piece 106a is first placed on the extending structure. The positioning post 102c on the top serves as a preliminary alignment. Next, the expansion plate fixing member fixes the positioning piece 10a to the extension structure 1〇2e of the second casing plate 1〇2b. Please refer to Figures 2 and 3 at the same time, which show two views of the expansion board fixture. The expansion plate fixing member 12A includes a pair of substantially parallel connecting pieces 121, a pressing piece 124, and a wrench portion 126. The pressing piece 124 is perpendicularly connected to the pair of connecting pieces 12, and the pressing piece 124 is provided with an opening 12 乜 and a groove 12 牝 to increase the degree of elasticity thereof. Further, the pressing piece 124 has an approximately "v"-shaped cross section, and the bottom end of the "V" shape is pressed against the positioning piece 1?6a. The wrench portion 126 extends outward from the pressing piece 124 to form a groove-like groove together. Referring to Figures 4A and 4B, the expansion plate fixing members of the second drawing of Figure 2 are assembled to the computer system of Figure 1. State. The expansion board fixing member 120 is pivotally connected to the rotating shaft of the extension structure 1Q2e by its shaft hole 122, so that the expansion board fixing member 120 can be rotated relative to the extension structure 1〇2e. The shaft hole 22 is a smear-shaped clip, and is divided into a first half hole 122a and a second half hole (the first half hole 122a and the second half hole (four) are the same size). Between the first half hole coffee and the first half hole 122b has a pair of common touch points n2e and, and the distance D between the conjugate card points is slightly smaller than the first half hole 122 & or the second half hole 200924611 (four), Therefore, the shaft can be snapped into the first half hole (four) or the hole. When the hinge coffee is snapped into the second half hole (10), the expansion plate fixing member m can be rotated in the direction 13G with respect to the extension structure as shown in Fig. 3B. When the expansion board fixing member 120 is in the state shown in Fig. 4B, the user can remove the expansion board 1〇6 from the main board 1〇4. When the expansion board is fixed! When the 2G is pressed down from the state of Fig. 4A in the direction (e.g., applied to the wrench portion 126), the hinge coffee is snapped into the first half hole 122& (as shown in Fig. 5). At this time, the pressing piece m of the expansion-plate fixing member 12〇 repeatedly catches the positioning piece 106a, so that the positioning piece i〇6a is sandwiched between [the piece 124 and the extension structure 1〇2£” and the expansion board The upper surface 126a of the wrench portion 126 of the fixing member no is cut to the top edge of the second body plate_.
