[0032] Working principle: In the initial state, the rack 410 is arranged inside the bottom column 40. The connecting plate 30 is clamped through the clamping block 32, the clamping groove 412 and the limiting plate 411. The abutting block 413 is arranged inside the first through groove 300. The side plate 33 shields the gap between the connecting plate 30 and the ventilation plate 414. At this time, the two connecting plates 30 and the protection device 4 protect the two side surfaces of the computer mainframe 1 and shield the computer mainframe 1 from the side at the same time, preventing dust from entering the inside of the computer mainframe 1. When the computer mainframe 1 needs to be used, manually rotate the connecting plate 30 counterclockwise by 180 degrees and manually fix the protection plate 460. The rotation of the connecting plate 30 causes the clamping block 32 to separate from the clamping groove 412. At this time, after the limiting plate 411 is no longer restricted by the clamping block 32 and the clamping groove 412, the first elastic member 41 inside the bottom column 40 elastically deforms and resets to drive the rack 410 to move upward. The movement of the rack 410 drives the limiting plate 411 to move upward. The movement of the limiting plate 411 exposes the ventilation plate 414 that was shielded by the connecting plate 30 and the limiting plate 411, so as to increase the ventilation effect when the computer mainframe 1 is running. The movement of the four racks 410 drives the four first gear discs 420 to rotate. Since the number of teeth of the rack 410 is greater than the number of teeth of the first gear disc 420, the first gear disc 420 needs to rotate several circles for the rack 410 to move once. The rotation of the first gear disc 420 drives the first movable wheel 421 to rotate through the first shaft rod 42. The rotation of the first movable wheel 421 drives the second movable wheel 440 to rotate through the movable belt 43. The rotation of the second movable wheel 440 drives the first bevel gear 441 to rotate through the second shaft rod 44. The rotation of the first bevel gear 441 drives the second bevel gear 442 to rotate. Since the number of teeth of the first bevel gear 441 is greater than the number of teeth of the second bevel gear 442, the second bevel gear 442 needs to rotate several circles for the first bevel gear 441 to rotate one circle. The rotation of the second bevel gear 442 drives the first screw rod 444 to rotate. The rotation of the first screw rod 444 drives the first through rod 445 to move in a straight line close to the computer mainframe 1. The movement of the four first through rods 445 drives the two protection bins 46 to move in a straight line close to the computer mainframe 1. Since the protection plate 460 has been manually fixed, at this time, the movement of the protection bin 46 causes the clamping member 463 to separate from the clamping column 461. The elastic deformation reset of the second elastic member 462 causes the protection plate 460 to pop out of the protection bin 46 and extend to the outside of the end of the protection device 4 away from the computer mainframe 1. At this time, there are two connecting plates 30 at the installation bottom plate 3 to support the computer mainframe 1 together, increasing the contact area with the ground so that the device is less likely to tip over. The protection plate 460 and the second elastic member 462 can buffer the left and right sides of the computer mainframe 1, preventing the computer mainframe 1 from being damaged when the user accidentally kicks the computer mainframe 1 with their feet or when an external force directly collides with the side of the computer mainframe 1 during use. The device has two different protection effects when closed and unfolded, improving the safety protection performance of the device and facilitating user use; In the initial state, the third gear disk 501 and the fourth gear disk 531 do not contact each other. When a user uses the computer host 1 under normal circumstances, the rotation drive assembly 53 is turned on. The rotation drive assembly 53 drives the rotation shaft 530 to rotate when it is turned on. The rotation of the rotation shaft 530 drives the fourth gear disk 531 and the rotating disk 532 to rotate. The rotation of the rotating disk 532 drives the rotating rod 533 to rotate. The rotation of the rotating rod 533 drives the return groove plate 534 to perform a reciprocating linear motion. Since there is a fourth shaft rod 535 at the return groove plate 534 for limiting, the return groove plate 534 can only perform a reciprocating swinging motion in this case. The movement of the return groove plate 534 drives the fifth gear disk 536 to move. The movement of the fifth gear disk 536 drives the toothed plate 54 to perform a reciprocating linear motion. The movement of the toothed plate 54 drives the slide rod 540 and the processing plate 541 to perform a linear reciprocating motion inside the two protection devices 4 through the second movable groove. The processing plate 541 performs a linear reciprocating motion to cool the computer host 1. At this time, the ventilation plate 414, the processing plate 541 and the computer host 1 form a complete air duct, making it easier for hot air to be discharged from the ventilation plate 414, improving the heat dissipation effect of the device. The linear reciprocating motion of the ventilation plate 414 can also perform air blowing treatment on the ventilation holes inside the ventilation plate 414, avoiding the dust adhering to the ventilation holes from reducing the ventilation effect of the device, thereby improving the stability of the normal operation of the computer host 1 and facilitating the user to use; When it is necessary to protect the USB interface of the computer host 1, the linear drive assembly 50 is turned on. The linear drive assembly 50 is turned on to push out and move the output rod 500. The movement of the output rod 500 drives the third gear disk 501 and the third bevel gear 502 to move until the third gear disk 501 meshes with the fourth gear disk 531 and the third bevel gear 502 meshes with the two fourth bevel gears 51. At this time, similarly to the above steps, the rotation of the third gear disk 501 drives the fourth gear disk 531, the linear drive assembly 50 and the output rod 500 to rotate. The rotation of the output rod 500 drives the third bevel gear 502 to rotate. The rotation of the third bevel gear 502 drives the two fourth bevel gears 51 to perform rotational movements in opposite directions. The rotation of the fourth bevel gear 51 drives the second screw rod 510 to rotate. The rotation of the two second screw rods 510 drives the two movable plates 52 to perform a linear motion of approaching each other. The movement of the movable plate 52 drives the shielding plate 520 to move through the first movable groove until the two shielding plates 520 shield the top of the computer host 1, thereby shielding the USB interface of the computer host 1 and preventing outsiders from directly stealing the user's personal information through the USB interface, improving the security protection function of the device and facilitating the user to use.
