[0015] The spindle fastener device for computer optical drives proposed in this utility model allows for the downward movement of a retaining frame at one end of the spindle by pressing a fixed rod inside the spindle. This downward movement causes a movable rod on the side of the retaining frame to extend and retract inward, locking onto the lower end of a movable component. Applying an upward pulling force to the fixed rod then causes the movable rod to move the movable component upward, locking it onto one end of the retaining rod. Continuing to apply an upward pulling force causes the movable rod to retract inward, bringing one end of the movable rod to the same plane as the inner wall of the retaining frame. Further applying an upward pulling force at this point causes the retaining frame to disengage from the retaining rod, allowing the entire disc to be removed for easy replacement and maintenance. This avoids the problem of not being able to replace damaged parts individually, thus increasing maintenance costs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-5 The present invention provides a technical solution: a shaft fastener device for a computer optical drive, the shaft fastener device for a computer optical drive includes: an optical drive motor 1, a placement disk 2 mounted on the surface of the optical drive motor 1, and a spindle 3 disposed on the surface of the placement disk 2;

[0024] Fixed rod 4, a clip frame 5 is fixedly installed at the lower end of fixed rod 4, a movable rod 8 is installed on the side of clip frame 5, clip rod 6 is set inside clip frame 5, and a movable part 7 is sleeved on the surface of clip rod 6;

[0025] In use, by pressing the fixed rod 4 inside the main shaft 3, the retaining frame 5 at one end of the fixed rod 4 is moved downward. The downward movement of the retaining frame 5 causes the movable rod 8 on the side of the retaining frame 5 to extend and retract inward and lock into the lower end of the movable part 7. Then, an upward pulling force is applied to the fixed rod 4, which will cause the movable rod 8 to drive the movable part 7 to move upward, so that the movable part 7 is locked into one end of the retaining rod 6. The upward pulling force is then continued to be applied, causing the movable rod 8 to retract inward, so that one end of the movable rod 8 is on the same plane as the inner wall of the retaining frame 5. At this time, the upward pulling force is continued to be applied, which will cause the retaining frame 5 to break free from the restriction of the retaining rod 6, thereby allowing the entire placement tray 2 to be removed for easy replacement and maintenance. This avoids the problem of not being able to replace damaged parts individually, which increases maintenance costs.

[0026] Example 2: Based on Example 1, a fixing rod 4 is provided to facilitate the disassembly of the component. A spring 15 is sleeved on the surface of the fixing rod 4. The spring 15 is locked between the surface of the connecting plate 14 and the top of the fixing rod 4. A spindle 3 is fixedly installed on the surface of the connecting plate 14. A magnet 16 is inserted into the surface of the spindle 3.

[0027] A limiting hole 17 is provided on the side of the card frame 5. The limiting hole 17 penetrates the tube wall on one side of the card frame 5. A movable rod 8 is provided in the limiting hole 17. A telescopic spring 18 is fixedly sleeved on the surface of the movable rod 8. The end of the movable rod 8 near the card rod 6 is stuck below the card cap 12. The end of the movable rod 8 near the card rod 6 can extend and retract into the limiting hole 17.

[0028] The lever 6 is fixedly installed on the surface of the drive block 9. A cap 12 is fixedly installed on the end of the lever 6 away from the optical drive motor 1. An overlapping groove is opened on the end of the cap 12 near the movable part 7, and the movable part 7 can be inserted into the overlapping groove.

[0029] To facilitate the disassembly of damaged parts of the device, the operator can press the fixing rod 4 to move the retaining frame 5 at one end of the fixing rod 4 downwards. Before the device is disassembled, the movable rod 8 on the inner side of the retaining frame 5 is locked at the lower end of the retaining cap 12 by the telescopic spring 18 in the limiting hole 17. When downward pressure is applied to the fixing rod 4, the movable rod 8 will move away from the retaining cap 12 towards the movable part 7. When one end of the movable rod 8 moves to the surface of the movable part 7, if it continues to move downwards, it will retract into the limiting hole 17. When the movable rod 8 moves below the movable part 7, the movable rod... Step 8 will reset, at which point the fixing rod 4 will be released. Under the action of the spring 15, the fixing rod 4 will have an upward pulling force. At this time, the retaining frame 5 will reset, and the movable rod 8 will drive the movable part 7 to move upward together. When the movable part 7 moves upward into the overlapping groove in the retaining cap 12, an upward pulling force is applied to the entire placement plate 2. The movable rod 8 located below the movable part 7 will retract into the limiting hole 17 until the movable rod 8 is completely retracted into the limiting hole 17. At this time, if the upward pulling force is continued, the part can be easily disassembled, thus facilitating the disassembly and replacement of the part.

[0030] Example 3: Based on Example 2, in order to enable the device to drive the optical disc to rotate, a placement disk 2 is provided. The surface of the placement disk 2 is provided with a locking hole 13, which passes through the fixing groove 11. A connecting plate 14 is fixedly installed on the surface of the placement disk 2. A circular groove is provided on the surface of the connecting plate 14 near the locking hole 13. A hole is provided at the top of the circular groove, and a fixing rod 4 is inserted into the hole. One end of the locking frame 5 abuts against the top surface of the circular groove. The locking frame 5 is located in the circular groove and the locking hole 13.

[0031] A fixing block 19 is fixedly installed on the surface of the drive block 9, and a placement plate 2 is connected to the surface of the drive block 9. A fixing groove 11 is opened on the surface of the placement plate 2 near the drive block 9, and a fixing block 19 is inserted into the fixing groove 11.

[0032] A drive board 10 is installed below the optical drive motor 1. Several mounting holes are opened on the surface of the drive board 10, and a drive block 9 is provided on the surface of the optical drive motor 1.

[0033] During installation, the fixing block 19 on the surface of the drive block 9 needs to be locked into the fixing groove 11 at the bottom of the placement disc 2, so that when the optical drive motor 1 rotates, it can drive the placement disc 2 and the spindle 3 to rotate, thereby enabling the device to drive the optical disc to rotate.

[0034] In actual use, by pressing the fixed rod 4 inside the main shaft 3, the retaining frame 5 at one end of the fixed rod 4 can be moved downward. The downward movement of the retaining frame 5 causes the movable rod 8 on the side of the retaining frame 5 to extend and retract inward and lock into the lower end of the movable part 7. Then, an upward pulling force is applied to the fixed rod 4, which will cause the movable rod 8 to drive the movable part 7 to move upward, so that the movable part 7 is locked into one end of the retaining rod 6. The upward pulling force is then continued to be applied, causing the movable rod 8 to retract inward, so that one end of the movable rod 8 is on the same plane as the inner wall of the retaining frame 5. At this time, the upward pulling force is continued to be applied, which will cause the retaining frame 5 to break free from the restriction of the retaining rod 6, thereby allowing the entire placement tray 2 to be removed for easy replacement and maintenance. This avoids the problem of not being able to replace damaged parts individually, which increases maintenance costs.
