In other embodiments, the pressing portion is slidably disposed on the fixed seat through the cooperation of the gear and the rack.

For example, the two blocking blocks 535 are integrally formed with the fixing base 531 and protrude from the fixing base 531 to stop the two elastic portions 5321 of the two snap elastic pieces 532 , respectively.

The opposite ends of the elastic element 536 abut against the pressing portion 5330 and the fixing seat 531 respectively, and the elastic element 536 is, for example, a compression spring.

The operation process of the operating member 533 will be described below. See Figures 4 to 7. FIG. 5 is a schematic side cross-sectional view showing that the elastic portion of the buckle spring is shielded by the shielding structure of the fixing seat. FIG. 6 is a view before the shielding of the shielding structure showing that the elastic part of the buckle spring is separated from the fixing seat. FIG. 7 is a schematic side sectional view showing the shielding of the shielding structure in which the elastic portion of the buckle spring is separated from the fixing seat.

As shown in FIG. 4 and FIG. 5 , when the pressing portion 5330 of the operating member 533 is in the vacated position, the pressing portion 5331 of the operating member 533 is located on one side of the elastic portion 5321 of the buckle spring 532 so that the shielding structure 5313 shields the elastic The portion 5321 is away from the side of the fixing portion 5320 , and the body portion 5121 of the positioning post 512 is limited by the elastic portion 5321 . In this way, the body 5121 can be prevented from moving from the narrow diameter section 5311 of the positioning hole 5310 to the wide diameter section 5312 of the positioning hole 5310 . In addition, since the shielding structure 5313 shields the elastic portion 5321 away from the fixing portion 5320 , the shielding structure 5313 prevents technicians from accidentally touching the elastic portion 5321 and affecting the position of the elastic portion 5321 on the body 5121 of the positioning post 512 . In addition, as shown in FIG. 4 , the slider 534 is located on one side of the sliding groove 5314 of the fixing base 531 and the locking member 537 is located on one side of the sliding groove 5332 of the pressing portion 5330 .

As shown in FIGS. 6 and 7 , when the pressing portion 5330 of the operating member 533 moves to the pressing position, the pressing portion 5331 of the operating member 533 presses against the elastic portion 5321 of the buckle spring 532 so that the elastic portion 5321 is released from the fixed position The shielding structure 5313 of the seat 531 is shielded, and the body 5121 of the positioning post 512 is separated from the limit of the elastic portion 5321 . In this way, the body 5121 can be moved from the narrow-diameter section 5311 of the positioning hole 5310 to the wide-diameter section 5312 of the positioning hole 5310 to detach the fixing seat 531 of the second mounting bracket 530 from the body 511 of the first mounting bracket 510 , that is, the second mounting bracket 530 is detached from the first mounting bracket 510 . In addition, as shown in FIG. 7 , when the pressing portion 5330 of the operating member 533 is at the pressing position, the stopper 535 will stop on the elastic portion 5321 of the buckle elastic piece 532 to limit the movement range of the elastic portion 5321 . Furthermore, as shown in FIG. 6 , when the pressing portion 5330 of the operating member 533 is at the pressing position, the elastic element 536 will be compressed. The compressed elastic element 536 can assist the pressing portion 5330 to move back to the vacated position again. In addition, as shown in FIG. 6 , the slider 534 is located on the other side of the sliding groove 5314 of the fixing base 531 and the locking member 537 is located on the other side of the sliding groove 5332 of the pressing portion 5330 .

The elastic element 536 of the present invention is optional. In other embodiments, the second mounting frame does not need to include the elastic element 536 and manually assists the pressing portion to move from the pressing position back to the receding position.

In addition, the stopper block 535 of the present invention is optional. In other embodiments, the second mounting frame does not need to include the stopper block 535 to manually limit the range of movement of the elastic portion of the buckle spring.

Furthermore, the second mounting bracket 530 of the present invention is optional, that is, the first mounting bracket 510 is not limited to be fixed to the frame body 300 through the second mounting bracket 530 . In other embodiments, the adapter assembly does not need to include the second mounting frame 530, and the first mounting frame is directly fixed to the frame body.

According to the electronic device and the riser assembly disclosed in the above-mentioned embodiments, since the riser card is electrically connected to the main circuit board through a cable instead of a gold finger, the riser card is not limited to be vertically disposed on the main circuit board , so as to increase the flexibility of arranging the riser card on the main circuit board. Moreover, the riser card electrically connected to the main circuit board through the cable can be arranged in any unused space of the electronic device, so that the limited space in the electronic device can be used more effectively.

In an embodiment of the present invention, the server of the present invention can be used for artificial intelligence (AI) computing, edge computing (edge computing), and can also be used as a 5G server, a cloud server, or a car networking server use.
