A head pad 8 is installed on one side of the second connecting plate 7.
[0023] In this embodiment, the combination of a fixing plate and a bracket forms a stable operating platform, effectively preventing potential damage from vibration and displacement when removing the read / write head assembly. The rotating design of the ring structure enhances operational flexibility, allowing the device to adapt to different hard drive models and their specific head positions, reducing the complexity and time consumption of the adjustment process. The sliding connection structure enables precise movement of key components, avoiding operational failures due to errors in traditional fixed designs, while also enhancing operational accuracy. The shims provide additional cushioning protection, preventing deformation or damage to the hard drive head due to external forces during disassembly.
[0024] Preferably, the first fixing plate 1 includes a first mounting plate 101, and a first side plate 102 is fixedly connected to both sides of the first mounting plate 101. A first mounting hole 103 is opened on the upper surface of the first side plate 102. The second fixing plate 2 includes a second mounting plate 201, and a second side plate 202 is fixedly connected to both sides of the second mounting plate 201. A second mounting hole 203 is opened on the upper surface of the second side plate 202. The two ends of the first bracket 3 and the second bracket 4 are respectively fixedly connected to the inner walls of the first mounting hole 103 and the second mounting hole 203.
[0025] The multi-layered mounting plate and bracket connection design enhances the overall stability of the device, and the various snap-fit methods enable quick assembly and disassembly of the read / write head assembly, improving operational efficiency. The mounting holes at both ends of the bracket provide excellent assembly flexibility, allowing for rapid adjustments to accommodate different hard drive models, significantly improving adaptability.
[0026] Furthermore, a slot 9 is provided on one side of the second connecting plate 7, and a buckle 10 is engaged with the inner wall of the slot 9. The buckle 10 is fixedly connected to one side of the magnetic head pad 8. A sliding groove 11 is provided inside the first connecting plate 5, and multiple limiting grooves 12 are provided inside the sliding groove 11. The limiting grooves 12 are semi-circular in shape.

The top of the spring block 15 is semi-circular in shape, and the outer wall of the spring block 15 is slidably connected to the inner wall of the limiting groove 12.
[0027] The combination structure of the slide groove 11 and the limiting groove 12 enables precise sliding and positioning of the operating components, enhances the control capability of the hard disk head disassembly and replacement process, and reduces operation failures caused by displacement errors. The slide groove 11 and the spring block 15 are designed together to provide stable rebound force using the spring 14 structure, making the operation process smoother and avoiding sudden vibrations caused by external forces, thereby protecting the head and disk.
[0028] The working principle and usage process of this utility model are as follows: The combination of the sliding groove 11 and the limiting groove 12 provides smooth sliding and positioning of the operating components.

The snap-fit structure further improves the efficiency of disassembly and assembly of the magnetic head assembly, while protecting the magnetic head and platter from external interference and damage. Through the organic coordination of sliding, positioning, support, and snap-fit functional modules, a precise, efficient, and stable hard drive magnetic head disassembly and assembly process is formed.
[0029] The procedure is as follows: Select the appropriate bracket according to the hard drive model, adjust and fix the positions of the mounting holes at both ends to ensure a stable connection between the extractor and the hard drive. Install the head assembly into the slide groove 11 on the device, and use the limiting groove 12 for precise positioning. At the same time, check whether the latch 10 is tightly engaged to ensure that the assembly is in a stable state. Slowly move the head assembly to the predetermined position through the sliding structure of the slide groove 11. Use the spring 14 and the spring block 15 to provide stable support to complete the operation and avoid displacement errors caused by external forces. During the head removal process, monitor the stability and positioning accuracy of the sliding process to ensure that the entire removal operation does not cause any damage to the head and the disk. After removal, use the snap-fit method to assemble or replace the head assembly to ensure that the new head assembly is securely fixed. After completing the disassembly and assembly work, clean the equipment and check the operating status of the slide groove 11 and the snap-fit structure to prepare for subsequent operations.
