[0016] Reference Figures 1-4 A novel external computer network security device includes: A fixed outer shell 1 is provided, and a support frame 5 is fixedly installed inside the fixed outer shell 1. A mounting plate 6 is fixedly connected to the top of the support frame 5. A safety device 3 is placed on the mounting plate 6. A connection port 19 is fixedly installed on the safety device 3. The safety device 3 is a publicly available technology. It is connected to a computer to monitor and manage the input and output data information. Its specific working principle will not be elaborated in detail. The safety device 3 is fixedly connected to the computer through the connection port 19. The heat dissipation structure includes a motor 9 fixedly connected to the inner wall of the fixed housing 1, a rotating rod 10 fixedly connected to the output end of the motor 9, a fan blade 11 fixedly installed on the rotating rod 10, ventilation holes opened on the side wall and top of the fixed housing 1, a filter screen fixedly installed at the ventilation hole, the fan blade 11 installed facing the ventilation hole on the side wall of the fixed housing 1, and a cleaning structure installed on the fixed housing 1. After the motor 9 starts, its output end drives the rotating rod 10 to rotate, which in turn drives the fan blade 11 fixedly installed on the rotating rod 10 to rotate, so that air enters from the vent hole on the side wall of the fixed housing 1 and exits from the vent hole at the top, which dissipates heat from the safety device 3. At the same time, the filter screen can block dust in the air, and the cleaning structure cleans this dust to prevent the filter screen from being blocked. The cleaning structure includes a mounting shell 14 fixedly connected to a fixed outer shell 1. The mounting shell 14 communicates with the interior of the fixed outer shell 1, and its position corresponds to the vent hole on the side wall of the fixed outer shell 1. A cleaning scraper 16 is slidably connected between the mounting shells 14. The cleaning scraper 16 is in contact with the filter screen on the side wall of the fixed outer shell 1, and the end of the cleaning scraper 16 in contact with the fixed outer shell 1 has a chamfer. A sliding block 17 is fixedly connected to the side wall of the cleaning scraper 16, and a sliding groove 15 corresponding to the sliding block 17 is formed on the mounting shell 14. A reciprocating lead screw 20 is rotatably connected to the lower inner wall of the fixed housing 1. A lead screw slider 21 is mechanically matched on the reciprocating lead screw 20. The lead screw slider 21 is fixedly connected to the corresponding sliding block 17. A fixed worm gear 12 is fixedly sleeved on the rotating rod 10. A connecting shaft 22 corresponding to the position of the fixed worm gear 12 is rotatably connected to the lower inner wall of the fixed housing 1. A fixed worm wheel 24 that meshes with the fixed worm gear 12 is fixedly sleeved on the connecting shaft 22. The connecting shaft 22 and the reciprocating lead screw 20 are connected by a belt drive assembly 23. When the rotating rod 10 rotates, the fixed worm 12, which is fixedly sleeved on the rotating rod 10, rotates accordingly, causing the fixed worm wheel 24, which meshes with the fixed worm 12, to rotate together, causing the connecting shaft 22 to rotate. Under the action of the belt drive assembly 23, the rotation of the connecting shaft 22 will cause the reciprocating screw 20 to rotate together. Since the screw slider 21 cannot rotate, the rotation of the reciprocating screw 20 will cause the screw slider 21 to move up and down reciprocally, causing the sliding block 17, which is fixedly connected to the screw slider 21, to move up and down together, causing the cleaning scraper 16 to move up and down reciprocally, cleaning the surface of the filter screen. The side wall of the fixed housing 1 has an opening, the position of which corresponds to the connection port 19. A fixing plate 13 is slidably installed on the inner wall of the opening, and the fixing plate 13 penetrates the inner wall of the opening. A threaded rod 18 is threadedly connected to the fixing plate 13. The threaded rod 18 penetrates the corresponding fixing plate 13 and is fixed together. The threads of the two threaded rods 18 are in opposite directions. The fixing plate 13 has an opening corresponding to each interface. The top end of the threaded rod 18 penetrates the inner wall of the fixed housing 1 and extends to the outer side of the fixed housing 1. A rotating block 4 is fixedly connected to the end of the threaded rod 18 located on the outer side of the fixed housing 1. The side wall of the rotating block 4 is engraved with anti-slip texture. When the threaded rod 18 with opposite threads rotates, the two fixing plates 13 will move in opposite directions. Rotating the rotating block 4 causes the threaded rod 18 to rotate, causing the fixed plate 13, which is threadedly connected to the threaded rod 18, to move in the opposite direction, thereby opening or closing the fixed plate 13. When the fixed plate 13 is opened, the optical fiber can be connected to the connector 19. When the fixed plate 13 is closed, the optical fiber can be clamped and the end of the optical fiber connected to the connector 19 can be fixed to prevent the optical fiber from separating from the connector 19. The support frame 5 adopts a telescopic structure, and a return spring is fixedly installed inside each support frame 5. A fixed spring 8 is fixedly installed on the upper inner wall of the fixed outer shell 1 through a damper. A fixed clamping block is fixedly connected to the bottom end of the fixed spring 8. The fixed clamping block presses on the top of the safety device 3. The damper and the fixed spring 8 work together to achieve the effect of buffering and shock absorption, reducing the impact of vibration on the device, which is conducive to the normal operation of the safety device 3. The top of the mounting plate 6 has a mounting groove 7, and the safety device 3 is fixedly placed in the mounting groove 7. The safety device 3 is positioned and installed through the mounting groove 7, which is beneficial for the installation and use of the device. The side wall of the fixed housing 1 is rotatably mounted with a fixed cover plate 2 via a rotating shaft. The position of the fixed cover plate 2 corresponds to the safety device 3, and a pull handle is fixedly installed on the fixed cover plate 2. Pulling the pull handle can open the fixed cover plate 2, thereby allowing maintenance and replacement of the equipment inside the fixed housing 1. The bottom of the fixed housing 1 is fixedly connected with multiple support legs, and each support leg is fixedly mounted with an anti-slip pad. The support legs and anti-slip pads support the fixed housing 1.

[0017] In this invention, when the device is in use, firstly, rotating block 4 is rotated to rotate threaded rod 18, causing fixed plate 13, which is threadedly connected to threaded rod 18, to move in the opposite direction, thereby opening fixed plate 13 and connecting optical fiber to connector 19. Then, rotating block 4 is rotated in the opposite direction to close fixed plate 13, clamping optical fiber and fixing the end of optical fiber connected to connector 19, preventing separation of optical fiber from connector 19. Safety device 3 is activated to manage the computer network security. Simultaneously, motor 9 is started. After motor 9 starts, its output end drives rotating rod 10 to rotate, thereby driving fan blades 11 fixedly mounted on rotating rod 10 to rotate, allowing air to enter through the vent holes on the side wall of fixed housing 1 and flow from the top. The air is vented to dissipate heat from the safety device 3. At the same time, the filter screen can block dust in the air. When the rotating rod 10 rotates, the fixed worm gear 12, which is fixedly sleeved on the rotating rod 10, rotates accordingly, driving the fixed worm wheel 24, which meshes with the fixed worm gear 12, to rotate together. This causes the connecting shaft 22 to rotate. Under the action of the belt drive assembly 23, the rotation of the connecting shaft 22 will drive the reciprocating screw 20 to rotate together. Since the screw slider 21 cannot rotate, the rotation of the reciprocating screw 20 will cause the screw slider 21 to move up and down, driving the sliding block 17, which is fixedly connected to the screw slider 21, to move up and down together. This causes the cleaning scraper 16 to move up and down accordingly, cleaning the surface of the filter screen and preventing the filter screen from being blocked.
