[0009] The rear positioning block has a lower convex portion at its base, which fits into a guide groove on the jig base. A guide sleeve is mounted on the lower convex portion. A guide rod is located at the bottom of the jig base, which engages the guide sleeve. Support bars are located on both sides of the base. Driven by the quick-action fixture, the lower convex portion moves back and forth along the guide groove, and the guide sleeve moves back and forth along the guide rod. The support bars prop up the jig base, providing space for the guide sleeve and guide rod.

[0010] The bottom of the jig base is equipped with a front plate and a rear plate. The front end of the guide rod is fixed to the front plate, and the rear end of the guide rod is fixed to the rear plate. The height of the front and rear plates is less than that of the support bar. The support bar provides space for the front and rear plates.

[0011] The push rod of the quick clamp is connected to the rear positioning block through a bolt and a nut. An external threaded part is fixed on the rear positioning block. The push rod is provided with a threaded hole. One end of the nut is provided with a limiting edge. One end of the bolt is screwed to the threaded hole. The nut fits on the bolt. The limiting edge is against the head of the bolt. The nut is screwed to the external threaded part. The nut presses the head of the bolt onto the external threaded part.

[0012] The worker loosens the nut, disengaging it from the externally threaded component. Then, the worker turns the bolt to adjust the length of the bolt's insertion into the push rod. The worker then tightens the nut, with its retaining edge pressing the bolt's head against the externally threaded component. As the combined length of the push rod and adjusting bolt increases or decreases, the initial position of the rear positioning block is adjusted to accommodate different hard drive models and sizes.
