System hard disk anti-interference device for network security

The invention discloses a system hard disk anti-interference device for network security, which comprises a hard disk frame for limiting and fixing a system hard disk to improve the anti-interference performance of the system hard disk, and the hard disk frame comprises a first hard disk frame and a second hard disk frame which are arranged in a mutually paired manner, two symmetrically-distributed mounting rods are fixedly mounted at the position, close to the butt joint position of the first hard disk frame and the second hard disk frame, of the first hard disk frame, first wedge blocks are fixedly connected to the ends of the mounting rods, and inserting grooves are formed in the position, close to the butt joint position of the second hard disk frame and the first hard disk frame, of the second hard disk frame. And two second wedge blocks which are symmetrically distributed and used for limiting and fixing the first wedge blocks are slidably installed in the inserting groove, reset assemblies matched with
