As a specific embodiment of the present invention, a friction block 333 is fixed to one end of the copper bar 33 in the shape of "L"; the connection stability of the copper bar 33 and the interface on the hard disk body 11 is enhanced through the friction block 333; during operation, when the interface of the hard disk body 11 extends into the first through hole 231, the friction block 333 on the copper bar 33 is attached and extruded at the interface of the hard disk body 11, at this time, the friction block 333 rubs with the interface of the hard disk body 11 once, the friction block 333 does not wear the interface of the hard disk body 11, and instead, the stability of the interface connection between the friction block 333 and the hard disk body 11 is enhanced.

When the hard disk drive works, after the interface of the hard disk body 11 is used for many times, the interface on the hard disk body 11 is abraded, so that the connection between the interface of the hard disk body 11 and the plug of the connecting wire is unstable, and therefore, an interface extension plate 23 is arranged at the interface of the hard disk body 11, so that the interface extension plate 23 replaces the interface of the hard disk body 11; when the hard disk body 11 is not placed in the protective shell 21, the dust blocking plate 3 in the first through hole 231 of the interface extension plate 23 is blocked at the hole of the first through hole 231, so that external dust is difficult to enter the first through hole 231; firstly, the hard disk body 11 is placed in the protective shell 21, in the placing process, the interface of the hard disk body 11 is inserted into the first through hole 231 of the interface extension plate 23, meanwhile, the end part of the interface of the hard disk body 11 is attached to and extrudes the dust blocking plate 3, then the dust blocking plate 3 extrudes the first spring 31 to be retracted into the first through hole 231, at the moment, the copper strip 33 is attached to the interface of the hard disk body 11, when the hard disk body 11 is used, only the plug of the connecting wire is inserted into the interface extension plate 23, and the interface of the hard disk body 11 is communicated with the plug of the connecting wire through the copper strip 33, so that the phenomenon that the interface connection of the hard disk body 11 is unstable after the interface of the hard disk body 11 is worn when the interface of the hard disk body 11 is directly connected with the; after the end of the interface of the hard disk body 11 extrudes the dust-blocking plate 3, the dust-blocking plate 3 slides to the middle position of the first through hole 231 along the inner wall of the first through hole 231, and simultaneously, the side wall of the third through hole 34 extrudes one end of the pressing plate 232 upwards to enable the pressing plate 232 to rotate around the hinge point of the pressing plate, then the other end of the pressing plate 232 moves downwards, then the pressing plate 232 presses the copper bar 33 downwards to enable the copper bar 33 to be pressed on the interface of the hard disk body 11, so that the stability between the copper bar 33 and the interface of the hard disk body 11 is enhanced, and the phenomenon that the copper bar 33 is separated from the interface of the hard disk body 11 after the hard disk body 11 is vibrated by the outside is avoided; in the process that the hard disk body 11 is placed into the protective shell 21, the hard disk body 11 presses the air bag 22 downwards, then the air bag 22 ejects air in the air bag 22 in the air nozzle 222 through the first pipeline 221, and then the air impacts at the hole of the first through hole 231 and the interface of the hard disk body 11, so that dust at the position of the first through hole 231 and dust at the interface of the hard disk body 11 are blown off, and the dust is prevented from being adhered to the copper bar 33 and the interface of the hard disk body 11 to influence the connection stability of the copper bar 33 and the interface of the hard disk body; in order to improve the stability of the hard disk body 11 in the protective shell 21 and facilitate the taking out of the hard disk body 11, when the hard disk body 11 is placed in the protective shell 21, the interface of the hard disk body 11 is inserted into the first through hole 231 of the interface extension plate 23, meanwhile, the threaded rod 42 is rotated, then the threaded rod 42 is rotated on the first plate 41 to move downwards, meanwhile, the threaded rod 42 presses the trapezoidal block 43 downwards, then the trapezoidal block 43 presses the push plate 44 downwards, then the push plate 44 presses the hard disk body 11, so that the hard disk body 11 is pressed in the protective shell 21 by the push plate 44, when the protective shell 21 is vibrated by the outside, the air bag 22 in the protective shell 21 buffers partial vibration to generate destructive force, and then the push plate 44 is matched to further press the hard disk body 11 in the protective shell 21, thereby preventing the occurrence of the disconnection phenomenon between the interface of the hard disk; after the copper bar 33 of the interface extension plate 23 is rubbed with the joint of the connecting line for multiple times, the copper bar 33 is abraded for multiple times, so that the copper bar 33 cannot be effectively connected with the joint of the connecting line, therefore, the abraded copper bar 33 needs to be sheared, and then the copper bar 33 extends out of the first through hole 231; when the push plate 44 extrudes the hard disk body 11, the end of the interface on the hard disk body 11 extrudes the receiving plate 331, and then the projection 332 on the receiving plate 331 slides along the inner wall of the first groove 233, so that the receiving plate 331 drives the copper bar 33 to extend out of the first through hole 231, at this time, the worn copper bar 33 is cut off, and the unworn copper bar 33 is attached and connected with the connector of the connecting line, so that the hard disk body 11 can be communicated with the connector of the connecting line; when the interface of the hard disk body 11 extends into the first through hole 231, the friction block 333 on the copper bar 33 is attached and extruded at the interface of the hard disk body 11, and at this time, friction occurs at the interface of the friction block 333 and the hard disk body 11 once, and the friction block 333 does not wear the interface of the hard disk body 11, but rather, the interface connection stability of the friction block 333 and the hard disk body 11 is enhanced.
