[0035] The structure of the first positioning member 201 and the second positioning member 21 can be set according to actual needs, and can be set to the cooperation between buckles, or can be set to the cooperation between threaded holes and screws, or can be set to the cooperation of magnetic structures. The installation positions of the first positioning member 201 and the second positioning member 21 can be selected according to actual needs, and it is only necessary to make the positions of the first positioning member 201 and the second positioning member 21 correspond to each other and be able to connect.

[0036] By setting the first positioning member 201 and the second positioning member 21, a mechanical interlock can be provided to fix the solid-state hard disk 200 in the placement slot 231, thereby improving the stability of the installation of the solid-state hard disk 200 and effectively preventing the solid-state hard disk 200 from moving when the tray assembly 20 is plugged in, thereby allowing the hard disk cabinet 100 to plug in the solid-state hard disk 200.

[0037] The technical solution of the utility model is to set a second positioning member 21 in the placement groove 231 of the tray assembly 20, and to provide a first positioning member 201 on the solid-state hard disk 200. The second positioning member 21 is connected to the first positioning member 201, so that the tray assembly 20 can carry and connect the solid-state hard disk 200.
