The memory card of the M.2 module necessarily has a gap 232. However, the card 230 of the present invention is not limited to the memory card of the M.2 module. The card 230 also includes a first positioning portion 234 that surrounds the inner wall of the gap 232. The buckle structure 130 further includes a second positioning portion 140 connecting the body 132, and the second positioning portion 140 has a screw hole 142. When the second positioning portion 140 abuts the notch 232, the first positioning portion 234 is located above the second positioning portion 140, and is locked into the screw hole 142 by the screw 600 to lock the first positioning portion 234 to the second positioning portion. 140, whereby the card 230 is securely locked to the buckle structure 130.

In the embodiment, each of the first fastening members 114 is a female snap member, and the second latch member 136 is a male snap member. The method of designing the first fastening member 114 as a concave fastening member can be achieved only by punching the substrate 110, and it is not necessary to add a convex portion, so that the card fixing device 100 is very simple to manufacture.

In the present embodiment, the sliding portion 112 is located on the side edge of the substrate 110. The joint 134 includes a bent portion 138 and a grip portion 139. The bent portion 138 is coupled to the body 132. The holding portion 139 is connected to the bent portion 138 and clamps the substrate 110 together with the body 132 to thereby restrain the degree of freedom of the buckle structure 130 in the first direction D1 such that the buckle structure 130 cannot be separated from the substrate 110 by the first direction D1. The engaging direction of the second fastening member 136 and one of the first fastening members 114 is parallel to the first direction D1, and the degree of freedom of the buckle structure 130 in the second direction D2 and the third direction D3 is restricted. The first direction D1, the second direction D2, and the third direction D3 are linearly independent from each other, whereby when the second fastening component 136 is engaged with one of the first fastening components 114, the buckle structure 130 is fixed to the substrate. 110 , and the card structure 230 is fixed to the substrate 110 by the buckle structure 130 .

The operation unit 152 is connected to the connection unit 150. Therefore, the user can apply the force to the first direction D1 by pulling the operation portion 152 to move the extension portion 135 to move in the first direction D1, so that the second fastening member 136 located at the extending portion 135 can be disengaged. The first fastening member 114 is thereby used for the purpose of unlocking. The operation portion 152 and the substrate 110 have a spacing d (see FIG. 3), which allows the user to extend the finger between the operation portion 152 and the substrate 110 to facilitate the user to apply force in the first direction D1.

In the present embodiment, the extending direction of the extending portion 135 is parallel to the sliding portion 112. When the user moves the buckle structure 130, the operating portion 152 needs to be pulled to apply a force to the second direction D2. Since the extending direction of the extending portion 135 is parallel to the sliding portion 112 (that is, the second direction D2), when the user pulls the operating portion 152, the pulling force applied to the second direction D2 can be directly transmitted by the extending portion 135 to move. The structure 130 is deducted to achieve the purpose of smoothly moving the buckle structure 130.
