In an embodiment of the present invention, the PCB fixing member 11 is connected to the fixing base 12 in a clamping manner. Specifically, referring to fig. 2 and fig. 3, the PCB fixing member 11 has a clamping portion 112, the fixing base 12 has 1 or more clamping interfaces 121, and the size of the clamping interface 121 matches with the size of the clamping portion 112. In specific application, the clamping portion 112 of the PCB fixing member 11 is clamped into the corresponding clamping interface 121, so that the PCB fixing member 11 and the fixing base 12 are clamped.

In an embodiment of the present invention, the PCB fixing member 11 has a supporting portion 113. When the PCB fixing member 11 is detachably disposed on the fixing base 12, the supporting portion 113 abuts against the fixing base 12 to enhance the connection strength between the PCB fixing member 11 and the fixing base 12. Preferably, the supporting portion 113 is a right triangle, and one right-angle side of the right triangle abuts against the fixing seat 12.
In a specific application, different expansion cards 2 may have different sizes, and in order to ensure that the split expansion card fixing device 1 is applicable to all expansion cards 2 as much as possible, so as to enhance the compatibility of the split expansion card fixing device 1, in an embodiment of the present invention, the fixing base 12 has a bottom plate 122; the bottom plate 122 is provided with a guide groove 123. The guide groove 123 is, for example, in the shape of an elongated hole. Preferably, the number of the guide grooves 123 is 3.

In an embodiment of the invention, the fixing base 12 further has a supporting wall 125, and two edges of the supporting wall 125 respectively abut against the side wall 124 and the bottom plate 122, so as to enhance the strength of the fixing base 12. Preferably, the support wall 124 is triangular.
In an embodiment of the present invention, the split-type expansion card fixing device 1 includes a PCB board fixing member 11 and a fixing base 12. The PCB fixing member 11 is used for fixing the PCB board 21 at the tail end of the expansion card 2.

Specifically, referring to fig. 5A, the bottom surface of the accommodating space in the electronic device 5 is provided with three screw hole groups 511, 512, and 513, wherein a distance between the screw hole group 511 and the connector 53 is L, and a distance between the screw hole group 511 and the connector 53 may be a distance between any positioning screw hole in the screw hole group 511 and the connector 53, for example, may be a distance between the positioning screw hole 5111 and the connector 53; the distance between the screw hole group 512 and the connector 53 is 3L/4, and the distance between the screw hole group 513 and the connector 53 is L/2; wherein, L is the standard size of the expansion card in the corresponding standard.
Further, the screw hole set 511 is matched with the screw connector, so that the split-type expansion card fixing device can be fixed near the screw hole set 511 (i.e. at a position corresponding to the screw hole set 511). In specific application, 3 threaded connectors are respectively screwed into corresponding positioning threaded holes in the threaded group 511 after penetrating through corresponding guide grooves on the split type expansion card fixing device, so that the split type expansion card fixing device can be fixed near the threaded group 511.
