Referring to fig. 3, in the present embodiment, the number of the ejection structures 300 is three, two of the ejection structures are respectively matched with the two first driving portions 112 of the first driving member 110, and the other ejection structure is matched with the second driving member 120; referring to fig. 5, the second driving member 120 further includes a second driving portion 122, and the second driving portion 122 is provided with a second driving surface 1221.

In this embodiment, two of the three ejection structures 300 are respectively used for contacting with two opposite ends of the slot 201, and the other ejection structure 300 is used for contacting with the middle of the slot 201, so that the display card device 10 can be more stably separated from the main board 20 by matching the three ejection structures 300 with the slot 201, thereby avoiding damaging the PCB 520, and having good use effect.

Further, referring to fig. 3 and 6, the graphics card apparatus 10 further includes a reset assembly 400, the reset assembly 400 includes a reset housing 410, a reset member 420 and a connecting member 430, the reset housing 410 is detachably connected to the fixing plate 510, the reset housing 410 is provided with a through hole 4111, the connecting member 430 is connected to the second driving member 120, the connecting member 430 is accommodated in the reset housing 410, the second driving member 120 is in sliding fit with the through hole 4111, and the reset member 420 is accommodated in the reset housing 410 and is respectively connected to the inner wall of the reset housing 410 and the connecting member 430.

Specifically, the second driving member 120 includes a second rod 121 and an operation portion 123, the connecting plate 130 is connected to the first driving member 110 and the second rod 121 respectively, the second rod 121 is in sliding fit with the connecting hole 610, the second rod 121 is in sliding fit with the fixing plate 510, the operation portion 123 is disposed on one side of the fixing plate 510 away from the heat dissipation fin set 600, the operation portion 123 is detachably connected to one end of the second rod 121, and the reset member 420 is configured to drive the second rod 121 to move along a direction from the operation portion 123 to the second rod 121; in the installation position, one end of the second rod 121 close to the operation portion 123 extends from the fixing plate 510, and drives the operation portion 123 to be spaced from the fixing plate 510. Referring to fig. 6, in the present embodiment, the restoring member 420 may be a coil spring, and in other embodiments, the restoring member 420 may also be an elastic member such as a plate spring or a spring plate, which is not limited herein.

In an embodiment, the operation portion 123 and the second rod 121 may be connected by a screw thread, so that the two are conveniently disassembled and assembled, and the operation portion 123 may limit the movement of the second rod 121, so as to prevent the second rod 121 from completely retracting into one side of the fixing plate 510 facing the heat dissipation fin set 600, and also facilitate a user to perform a corresponding operation on the operation portion 123, which is good in use effect.

Specifically, in one embodiment, the reset housing 410 includes a housing body 411 and a connecting portion 412, the connecting portion 412 is protruded on an outer wall of the housing body 411 and is used for connecting with the fixing plate 510; when assembling the reset assembly 400 of this embodiment, the connecting member 430 and the second rod 121 are first fixed, and then the reset member 420 is sleeved on the second rod 121, and opposite ends of the reset member 420 are respectively abutted against the connecting member 430 and the fixing plate 510, and then the reset shell 410 is connected to the fixing plate 510; by this arrangement, the reset piece 420 can be sealed in the reset housing 410, so as to prevent the reset piece 420 from contacting with dust or impurities to affect the reset effect.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
