In addition, since the first end 124a of the cantilever 124 is the hook portion 122, the second end 124b is suspended. After the cantilever 124 passes through the through hole 114 of the body 110, the second end 124b is slightly tilted to abut against the through hole 114. The body 110. As a result, the hook portion 122 of the fixing member 120 abuts against the second bent portion 12 a of the interface card bracket 12 , and the second end 124 b of the cantilever 124 of the fixing member 120 abuts against the body 110 . That is to say, the casing 20, the interface card bracket 12, the present The relative position between the body 110 and the fixing member 120 can be fixed. At this time, the fixing member 120 is located at a locking position P1 with respect to the body 110. As shown in FIG. 2, the hook portion 122 of the embodiment includes a notch 122c. When the fixing member 120 is located at the engaging position P1 with respect to the body 110, the notch 122c is adapted to avoid the interface card 14 to avoid the interface card 14 or The other electronic components are blocked from being fixed to the engagement position P1.

When the user wants to remove the interface card module 10, firstly, the second end 124b of the cantilever 124 can be pressed to move the second end 124b away from the body 110 and retreat to the through hole 114. At this time, the fixing member 120 is removed. It is movable relative to the body 110. Then, the fixing member 120 is rotated in a second rotation direction R2 to allow the cantilever 124 to withdraw from the through hole 114. In the process, the fixing member 120 is rotated relative to the body 110 from the engaging position P2 to a disengaging position P1. Figure 3 is a schematic view of the fixing member of the fixing device of Figure 1 in a disengaged position. Referring to FIG. 3, since the cantilever 124 of the fixing member 120 is withdrawn from the through hole 114, the second bent portion 12a of the interface card holder 12 is no longer subjected to the first surface 122a and the second surface 122b of the hook portion 122 of the fixing member 120. The abutment can be separated from the first bent portion 22 of the casing 20.

In addition, in order to make the body 110 of the fixing device 100 more stably disposed on the casing 20, in the embodiment, the fixing device 100 further includes a screw 130, and the casing 20 includes a second screw hole 26 corresponding to one of the screws 130.

And the screw 130 is fixed to the casing 20 in a locking and locking manner to ensure that the body 110 is fixed to the casing 20 .

In addition, it can be seen that the hole 128a of the card holder 128 corresponds to the first screw hole 118 of the body 110. The hole 128a can be screwed into the second screw hole 26 and the first screw hole 118. Of course, if the length of the screw 130 is short, the hole 128a may not be worn. In addition, in the embodiment, the first pivoting portion 116 of the body 110 and the first screw hole 118 are located on different planes, but in other embodiments, the relative positions of the first pivoting portion 116 and the first screw hole 118 may be It varies depending on factors such as the shape of the interface card 14.

Moreover, the fixing device 100 of the embodiment is pivotally connected to the body 110 by the fixing member 120, and the interface card bracket is moved by rotating the fixing member 120 relative to the body 110 between the engaging position P1 and the disengaging position P2. 12 is pressed against the casing 20 or releases the interface card holder 12. Therefore, the interface card holder 12 of the interface card module 10 can be fixed to the casing 20 without being locked, and only the fixing member 120 needs to be rotated, which is more convenient and simple to disassemble.

In addition, in the embodiment, the card holder 128 of the fixing member 120 is located between the second pivoting portion 126 and the hook portion 122. When the fixing member 120 is rotated to the engaging position P1, the card holder 128 of the fixing member 120 is As shown in FIG. 1, the body 110 is restrained to restrict the rotation of the fixing member 120 in the first rotational direction R1. Therefore, the fixing member 120 can be restricted by the body 110 through the card holder 128 to auxiliaryly limit the range of rotation of the cantilever 124 of the fixing member 120 after passing through the through hole 114 of the body 110.

Figure 4 is the fixing device of the fixing device of Figure 1 in the engaged position to be introduced A schematic view of another aspect of the face card module fixed to the casing. Referring to FIG. 4, since a plurality of interface card slots (not shown) are provided on a general motherboard (not shown) for interposing the interface card 14 of the plurality of interface card modules 100, the user can A fixing device 100 is disposed on each of the casings 20 adjacent to the interface card module 100 to fix the interface card bracket 14 of the interface card module 10. As shown in FIG. 4, three sets of fixing devices 100 are disposed on the casing. Of course, the number of the fixing devices 100 disposed on the casing 20 is not limited thereto. The number of the interface card slots of different motherboards is different, and the user can set the fixing device 100 of the embodiment to the interface card according to the needs of the user. On the casing 20 next to the slot.

In summary, the fixing device of the present invention is mounted on the casing through the hook of the main body, and the second bending portion of the interface card bracket is pivoted to the first bending portion of the casing. The fixing member of the body passes through the through hole, and the first surface and the second surface perpendicular to the hook portion abut against the second bending portion to fix the relative position between the interface card bracket and the casing . Moreover, since the second end of the cantilever also passes through the through hole and abuts against the body, the relative position of the body and the fixing member can be fixed. When the engagement between the interface card bracket and the housing is to be released, the second end of the cantilever is pressed to move the second end away from the body and moved to the side of the through hole, and the fixing member is rotated to allow the hook portion and the cantilever to exit The through hole and the fixing member can be rotated from the engaged position to the disengaged position with respect to the body. At this time, the second bent portion of the interface card bracket can be separated from the first bend of the casing without being abutted by the hook portion. unit.
