The invention relates to the technical field of computer hard disks, and discloses a hard disk crushing device that automatically adjusts the degaussing speed based on the crushing speed. Iron, the bottom of the electromagnet is connected with a connecting shaft, the bottom of the connecting shaft is connected with a threaded rod, the threaded rod is provided with a slider, the slider is connected with a movable degausser, the top of the threaded rod is connected with a driving gear, and the bottom of the crushing device Set with rotating gears. The hard disk crushing device that automatically adjusts the degaussing speed based on the crushing speed is provided with a rotating gear under the crushing device, and the rotating gear is connected with the driving gear through a chain belt. When the crushing device rotates and drives the rotating gear to rotate, it passes The chain belt synchronously realizes the rotation of the drive gear, thereby realizing the motion degaussing of the movable degausser indirectly connected with it.
Description
technical field [0001] The invention relates to the technical field of computer hard disks, in particular to a hard disk shredding device that automatically adjusts the degaussing speed based on the shredding speed. Background technique [0002] The computer hard disk is the main storage device of the computer. Most of the software required for the normal operation of the computer is stored on the hard disk. It is composed of one or more aluminum or glass discs, and the discs are covered with ferromagnetic materials. . [0003] In today's highly developed informatization, for people whose hard disk contains sensitive information, if they directly discard or resell the hard disk, it is very easy to cause important data leakage. To completely delete, the hard disk needs to be completely shredded to ensure that the data in the hard disk can no longer be read, thus giving birth to the development of hard disk shredders. [0004] However, if you only use a hard disk shredder to...
