Referring to fig. 1 to 4, the fixing device 100 of the present embodiment is suitable for being disposed on a board 10 for fixing an object 20 detachably disposed on the board 10. In the present embodiment, the plate 10 includes a plate 12 and a nut seat 14 (fig. 4) fixed on the plate 12. Specifically, the board 12 is, for example, a circuit board, and the object 20 is, for example, an m.2 expansion card, but the kinds of the board 12 and the object 20 are not limited thereto. The securing device 100 is removably disposed on the nut seat 14 (fig. 4) of the plate body 12. The board 10 further includes a slot 18 (fig. 1) disposed on the board body 12, where the slot 18 is, for example, an m.2 slot, but the type of slot 18 is not limited thereto. One end of the object 20 (e.g., an m.2 expansion card) is inserted into the slot 18, and the other end of the object 20 (e.g., an m.2 expansion card) is fixed by the fixing device 100, so that the object 20 (e.g., an m.2 expansion card) can be firmly fixed to the board 12 (e.g., a circuit board).

The fixing device 100 of the present embodiment can be easily and conveniently fixed to the nut seat 14 (fig. 4) on the plate 12, and can achieve the effect of quick fixing or releasing by a bare-handed operation. The fixture 100 and related components will be described below.

As shown in fig. 4, the fixing device 100 includes a base 105, and the base 105 includes a main body 110, a fixing portion 135 and a positioning portion 130 extending from a bottom surface 112 of a bottom plate 111 of the main body 110. The fixing portion 135 is adapted to be fixed to the board 10. The nut seat 14 includes a screw hole 15 and a positioning groove 16. The fixing portion 135 is, for example, a stud, and can be screwed into the screw hole 15 of the nut seat 14, but the manner in which the fixing portion 135 is fixed to the plate 10 is not limited thereto.

Fig. 5 is a partial schematic view of the fixing device of fig. 1 before the positioning portion enters the positioning groove of the nut seat. Referring to fig. 5, the positioning portion 130 includes a stop surface 131 perpendicular to the bottom surface 112 and a first inclined surface 132 inclined with respect to the bottom surface 112, and the positioning groove 16 includes a second inclined surface 17 corresponding to the first inclined surface 132. In this embodiment, when the fixing portion 135 is screwed to the screw hole 15, the main body 110 gradually approaches the nut seat 14.

Fig. 6 is a schematic view of the positioning portion of the fixture of fig. 1 entering the positioning groove of the nut seat. Referring to fig. 6, in the present embodiment, the nut seat 14 is positioned on the plate 12 in a specific direction, the screw hole 15 of the nut seat 14 has a predetermined internal thread start point, and the fixing portion 135 also has a predetermined external thread turn number. Therefore, when the fixing portion 135 is completely screwed into the screw hole 15 of the nut seat 14, the positioning portion 130 is located in the positioning groove 16.

At this time, the first inclined surface 132 of the positioning portion 130 faces the second inclined surface 17 of the positioning groove 16. The stop surface 131 of the positioning portion 130 is limited by the vertical wall surface of the positioning groove 16, so that the fixing portion 135 cannot rotate downward, and the main body 110 can be accurately positioned, so that the main body 110 can face a specific direction when being fixed on the board 10. Such a design may enable the subsequent fixture 100 to be oriented in a particular direction toward the article 20 to hold the article 20 well.

In the present embodiment, the height H1 (fig. 8) of the positioning portion 130 protruding from the bottom surface 112 is smaller than or equal to the pitch H2 (fig. 8) of the fixing portion 135, so as to avoid interference between the positioning portion 130 and the board 12. In addition, when the fixing portion 135 is to be separated from the nut seat 14, since the first inclined surface 132 faces the second inclined surface 17, the first inclined surface 132 can follow the second inclined surface 17 as long as the base 105 is reversed, so that the fixing portion 135 can smoothly rotate upwards.

In addition, referring back to fig. 4, in the present embodiment, the bottom plate 111 of the main body 110 includes a first portion 114, a second portion 115, and a hollowed-out area 116 between the first portion 114 and the second portion 115. The fixing portion 135 protrudes from the first portion 114, and the positioning portion 130 protrudes from the second portion 115, where the thickness of the second portion 115 is smaller than that of the first portion 114. The hollowed-out area 116 may provide a space for the first portion 114 to collapse, so that the first portion 114 may be easier to deform, and the positioning portion 130 on the first portion 114 may also be more elastically moved when entering or exiting the positioning groove 16.
