Since the first support structure 1111 is a fixed-position structure, and the movable member 21 is movable along the first direction D1. It is provided on the first side 111, so the returning elastic force of the elastic element 22 will push the movable member 21 to move along the linear path LR toward the first direction D1 to the first position. In practice, the elastic element 22 is in an elastically compressed state when it is disposed on the first side 111 and contacts the movable element 21 .

The bent extension is used to limit the rotation angle of the hinged fixed cantilever 24 relative to the movable buckle 23 . The second buckle end 242 is formed by bending and extending from the edge of the body of the hinged fixed cantilever 24 , and the second buckle end 242 is also provided with a second underhook structure 2421 .

Please continue to refer to Figures 6 and 7. Figure 6 shows the movable buckle of the cantilever-fixed expansion card tray provided by the preferred embodiment of the present invention. The first buckle end and the second buckle are rotated. A schematic three-dimensional view of the buckle ends respectively abutting the first buckle structure and the second buckle structure; the seventh figure shows the movable buckle component of the cantilever-fixed expansion card tray provided by the preferred embodiment of the present invention A schematic three-dimensional view of the first buckle end and the second buckle end being buckled in the first buckle structure and the second buckle structure respectively after being rotated to the buckling angle.

As shown in the first to seventh figures, when the hinged fixed cantilever 24 pivots along a first pivot direction R1 from the position in the second figure to the position in the fifth figure, the extending directions of the hinged fixed cantilever 24 are opposite to each other. The angle in the first direction D1 is a pressing angle, and when the hinged fixed cantilever 24 rotates in the first pivot direction R1, it also contacts the movable buckle 23 through the rotation stop piece 2411, thereby causing the hinge to rotate. The fixed cantilever 24 is maintained at the pressure angle.

Based on the above, when the hinged fixed cantilever 24 is at the position of the pressing angle, the user can press the hinged fixed cantilever 24 down along a second pivot direction R2, thereby driving the movable buckle 23 to pivot. The end 231 is the rotation axis, pivoting along the second pivot direction R2 from the position in the fifth figure; when the movable buckle 23 rotates along the second pivot direction R2 to the position in the sixth figure, the movable buckle The fastener 23 will drive the first barb structure 2321 of the first buckle end 232 and the second barb structure 2421 of the second buckle end 242 to abut against the first buckle structure 13 and the second buckle structure respectively. 14. At this time, if the movable buckle 23 continues to rotate along the second pivot direction R2, because the first buckle structure 13 is fixedly provided on the first side 111, the movable buckle 23 will move along the second pivot direction R2. The reverse retreat in one direction D1 drives the movable component 21 connected to the pivot end 231 to move in the reverse direction along the first direction D1, thereby further compressing the elastic component 22, and then when the movable buckle 23 continues to move along the When the movable buckle 23 is rotated in the second pivot direction R2 to a buckling angle as shown in the seventh figure, the first buckle end 232 and the second buckle end 242 will pass through respectively. The first buckle structure 13 and the second buckle structure 14. At this time, the elastic force accumulated by the elastic element 22 being compressed will drive the movable member 21 to move along the first direction D1, and then drive the first buckle end 232 and the second buckle structure. The buckle end portion 242 moves along the first direction D1 to buckle with the first buckle structure 13 and the second buckle structure 14 respectively.

In this embodiment, the buckling angle of the movable buckle 23 is 0 degrees, and the buckling angle specifically refers to the angle between the extension direction of the movable buckle 23 and the first direction D1. In addition, since the bracket body 1 of this embodiment is also provided with a stopper 15 on the first side 111, when the movable buckle 23 rotates along the second pivot direction R2, the stopper 15 can also be used to 15 abuts against the abutting side 234 to stop the rotation of the movable buckle 23, thereby keeping the movable buckle 23 parallel to the first direction D1 and maintaining the buckle angle.

As mentioned above, when the hinged fixed cantilever 24 rotates to the pressing angle along the first pivot direction R1, and the movable buckle 23 rotates to the buckling angle along the second pivot direction R2, due to the hinged fixed cantilever 24 will be fixed to the first side 111 and the second side 121, so an expansion card (not shown in the figure) disposed between the first side 111 and the second side 121 can be resisted by the hinged fixed cantilever 24 The first buckle end 232 and the second buckle end 242 are respectively buckled with the first buckle structure 13 and the second buckle because the elastic force of the elastic element 22 is pushed in this embodiment. Therefore, even if the entire cantilever-fixed expansion card tray 100 is shaken or impacted, the hinged fixed cantilever 24 will move along the first side 111 and the second side 121 . The kinetic energy of the reverse movement in the first direction D1 can also be absorbed by the elastic element 22, thereby continuously fixing the hinged fixed cantilever 24 to the first side 111 and the second side 121, effectively utilizing the hinged fixed cantilever. 24 Continue to press and hold the expansion card and the PCIe device installed on the expansion card.

In addition, when the user needs to unfasten the hinged fixed cantilever 24, the user can press the operating structure 235 to drive the movable buckle 23 to move in the reverse direction along the first direction D1, thereby causing the first buckle end to move in the reverse direction. 232 and the second buckle end 242 are respectively disengaged from the first buckle structure 13 and the second buckle structure 14, and then the movable buckle 23 can be further moved in the opposite direction of the second pivot direction R2. Rotate, and reversely rotate the hinged fixed cantilever 24 along the first pivot direction R1, so that the user can install or remove the expansion card.

To sum up, compared with the previous method of using screws to lock the support bracket to the expansion card rack, problems such as screw loosening or iron plate deformation may easily occur due to vibration or impact. The present invention uses elastic components to provide The elastic force used to fix the hinged fixed cantilever to the first side and the second side can indeed absorb the energy of vibration or impact through the elastic element, thereby effectively preventing the hinged fixed cantilever from detaching from the first side and the second side. The second side is used to fix the expansion card.
