Hard disk tester

The utility model relates to a hard disk tester, which comprises a testing jig and a testing cylinder and also comprises a shockproof rubber pad and a testing cylinder bracket. The shockproof rubber pad is a circular cylinder, and a central open pore is arranged in the axial direction of the shockproof rubber pad. An annular waist open groove is arranged in the direction perpendicular to the axial direction on the outer surface of the shockproof rubber pad. The width of the open groove equals the thickness of a switching card clamped and fixed at the testing cylinder bracket on the testing cylinder. The testing jig is right-angle bend-shaped. A section of the testing cylinder bracket is fixed on and in parallel with the testing cylinder side face through the shockproof rubber pad and screw bolts inlaid on the section of the testing cylinder bracket. The end face of the inner side of the shockproof rubber pad is in contact with the switching card. The other section of the testing cylinder bracket is fixed on and in parallel with the testing jig through the shockproof rubber pad and screw bolts inlaid on the other section of the testing cylinder bracket, and extends toward the direction of the outside of the opening of the testing cylinder. The end face of the inner side of the shockproof rubber pad is in contact with the testing jig. The design for earthquake proof of the utility model can all fully reduce the influence of the ambient vibratory on the hard disk in test.
