[0023] Specifically, the switch assembly 3 includes a fixing slot 31, a fixing block 32, an auxiliary assembly 33, a transmission block 34, a screw 35 and a through slot 36. The inner side of the side panel 4 is provided with a fixing slot 31, and the interior of the cover 1 is provided with two through slots 36. The transmission block 34 is embedded in the through slot 36, and the outer side of the transmission block 34 is connected to the fixing block 32. The interior of the transmission block 34 is embedded with a screw 35, and the side end of the screw 35 is connected to the auxiliary assembly 33. The thread direction of the surface of the screw 35 inside the two through slots 36 is an idea, and the fixing block 32 and the fixing slot 31 are a plug-in structure.

[0024] By adopting the above technical solution, the rotating screw 35 is engaged with the transmission block 34, and the through groove 36 limits the transmission block 34. Since the thread directions of the two end surfaces of the screw 35 are opposite, the two transmission blocks 34 can respectively drive the fixed blocks 32 to move toward each other. After the fixed block 32 is separated from the fixing groove 31, the machine cover 1 can be removed, which can make the opening and closing operation of the machine cover 1 simpler and the structural stability higher.

[0025] Specifically, the surface of the transmission block 34 is tightly fitted with the inner wall of the through slot 36 , and the two transmission blocks 34 are centrally symmetrically positioned inside the cover 1 .

[0027] Specifically, the auxiliary component 33 includes a rotating block 331, a side block 332 and a control groove 333. The side end of the screw 35 is connected to the side block 332. The control groove 333 is opened inside the side block 332. The surface of the screw 35 inside the machine cover 1 is covered with a rotating block 331, and the rotating block 331 has a circular ring structure.

[0028] By adopting the above technical solution, the rotating block 331 plays a limiting role, which can limit the rotation of the screw 35 to facilitate the control of the movement of the fixed block 32. The rotation of the screw 35 can be controlled by the control groove 333 on the surface of the side block 332. The control groove 333 is a hidden control structure, which can make the use of the device better.

[0029] When this embodiment is in use, the air permeable plate 2 on the surface of the cover 1 can be used for rapid heat dissipation of this network firewall device. When the screw 35 is engaged with the transmission block 34, the through groove 36 limits the transmission block 34. Since the thread directions of the surfaces at both ends of the screw 35 are opposite, the two transmission blocks 34 can respectively drive the fixed blocks 32 to move toward each other. After the fixed block 32 is separated from the fixed groove 31, the cover 1 can be removed, which can make the switch operation of the cover 1 simpler and the structural stability higher. The rotating block 331 plays a limiting role, which can limit the rotation of the screw 35 to facilitate the control of the movement of the fixed block 32. The rotation of the screw 35 can be controlled by the control groove 333 on the surface of the side block 332. The control groove 333 is a hidden control structure, which can make the use of the device better.
