In this embodiment, as shown in FIG. 5, when the expansion card 200 is inserted at least partially into the accommodating space S through the opening O of the bracket 110, the fixing portion 130 rotates about the axis X relative to the pressing portion 120, and the second buckle The portion 131 enters the accommodating space S of the bracket 110, and the protrusion 131b presses against the inner wall of the bracket 110 and slides against the inner wall, so that the elastic piece 131a is elastically deformed and stores a certain amount of elastic potential energy. When the protrusion 131b of the second buckle portion 131 reaches the second through hole H2 of the bracket 110, the protrusion 131b no longer presses against the inner wall of the bracket 110, and the elastic piece 131a releases the stored elastic potential energy and makes the protrusion The output piece 131b may be located in the second through hole H2 of the bracket 110. At this time, the locking between the second locking portion 131 of the fixing portion 130 and the first locking portion 111 of the bracket 110 is also completed. Since the process of buckling between the second buckling portion 131 of the fixing portion 130 and the first buckling portion 111 of the bracket 110 is simple and easy, and no additional tools are required, it can bring convenience to the user. In this situation, as described above, the protruding structure 132 of the fixing portion 130 faces and presses the buckle piece 210 of the expansion card 200 to fix the relative position of the expansion card 200 and the bracket 110.

On the contrary, when the user presses the protruding part 131b of the fixing part 130 to make the protruding part 131b leave the second hole H2 of the bracket 110, the user can rotate the fixing part 130 relative to the pressing part 120 around the axis X, and make the fixing part 130 no longer covers the opening O of the bracket 110 at least partially. In this way, the user can take the expansion card 200 out of the bracket 110. Since the process of releasing the buckle between the second buckle portion 131 of the fixing portion 130 and the first buckle portion 111 of the bracket 110 is simple and easy, and no additional tools are required, it can bring convenience to the user.

In addition, as shown in FIGS. 4 to 5, the fixing portion 130 has at least one recessed portion R, and the recessed portion R at least partially extends along the second direction D2. When the locking structure 100 is installed in the housing 310 along the second direction D2, the structure (not shown) next to the computer device 300 can be at least partially accommodated in the recess R of the fixing portion 130 to avoid position and Space saving effect.
