[0021] See also Figure 1-Figure 3, a self-locking rotating shaft system with unlocking and self-spinning release, including a locking part 2, which is a long plastic part. The locking part 2 is arranged on the side of the casing 1 where the server is inserted into the functional module, generally distributed at the corner position of the server casing, for locking the inserted functional module, which can be a PCIE module, etc. One end of the locking part 2 is rotatably connected to the casing 1 through a first rotating shaft 3, and the other end of the locking part 2 is a locking end 21. In order to facilitate the fastening of the locking part 2, a handle 24 can be provided on the top of the locking part 2. To achieve automatic locking of the latch end 21, a locking member 5 is provided within the latch end 21. The middle portion of the locking member 5 is rotatably connected to the latch end 21 via a second rotating shaft 53. A locking hook 51 is provided at one end of the locking member 5, which is compatible with the locking rod 7. A pressing portion 52 is provided at the other end of the locking member 5. A locking torsion spring 54 is sleeved around the second rotating shaft 53. The locking torsion spring 54 has one arm secured to the latch end 21, while the other arm is secured to the locking member 5. A locking rod 7, compatible with the locking member 5, is provided at a position on the housing 1 corresponding to the locking member 5. When the latch 2 is engaged with the locking rod 7, the locking hook 51 of the locking member 5 is automatically lifted upward and engaged with the locking rod 7 under the action of the locking torsion spring 54. To unlock the latch, the pressing portion 52 is pressed downward to lift the locking hook 51, disengaging it from the locking rod 7.

[0022] A locking portion 22 for limiting the server insertion function module is provided in the middle of the locking member 2. A clamping cavity is formed between the locking portion 22 and the housing 1. A clamping portion adapted to the clamping cavity is provided on the server insertion function module.

[0023] A release torsion spring 4 is sleeved on the first rotating shaft 3. The force arm of one end of the release torsion spring 4 is fixed on the housing 1, and the force arm of the other end is fixed on the lock member 2. After the lock hook 51 is disengaged from the lock rod 7, the lock member 5 is unlocked, and the lock member 2 is released by self-spinning under the push of the release torsion spring 4. In order to limit the position of the lock member 2 when it is fastened, an upper limit mechanism is provided between the upper part of the lock member 2 and the casing 1, and the upper limit mechanism includes an upper limit column 61 and a limit groove 23 that are adapted to each other. The upper limit column 61 is fixedly arranged on the casing 1, and the limit groove 23 is arranged on the lock side of the lock member 2. In order to limit the position of the lock member 2 after it is released by self-spin, a lower limit mechanism is provided between the lower part of the lock member 2 and the casing 1, and the lower limit mechanism includes a lower limit column 62 and a limit protrusion 25 that are adapted to each other. The lower limit column 62 is fixedly arranged on the casing 1, and the limit protrusion 25 is arranged at the bottom of the lock member 2. When the lock member 2 is released by self-spin, the lower limit column 62 will block the limit protrusion 25, which is used to limit the self-spin release opening angle of the lock member 2.

[0024] The unlocked and self-released rotating shaft system of the utility model is self-locking, occupies a small space, and can realize the functional requirements of the assisted installation wrench under extremely small structural space requirements, and can ensure smooth and effective docking of the plug-in module operation process. The operation steps are simple and easy, which can significantly improve the quick maintenance operation experience and efficiency of the operation and maintenance personnel. The self-locking function can be completed during the operation process, and the unlocked state is automatically opened, which can significantly improve the quick maintenance operation experience and efficiency of the operation and maintenance personnel.

[0025] Specifically, when in use, first release the locking member 2 and put it in the open state, then insert the server insertion function module into the installation position, and then close the locking member 2, so that the locking part 22 of the locking member 2 limits and fixes the clamping part of the server insertion function module, thereby realizing the functional requirements of the assisted installation wrench, so that the plug-in module can be smoothly docked and fixed. When it is necessary to remove the insertion function module, it is only necessary to press down the pressing part 52 to release the lock of the locking member 5, and the locking member 2 will automatically spin to release and open. The operation steps are simple and easy, which can significantly improve the quick maintenance operation experience and efficiency of the operation and maintenance personnel.

[0026] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
