[0002] The functions of an invisible hinge mainly include enabling the smooth opening and closing of a door, maintaining the beauty of the interior, and having a certain adjustment function. An invisible hinge is a common door hardware fitting used in modern home decoration. It is mainly used to connect a door leaf and a door frame, enabling the door to open and close smoothly. At the same time, due to its structural design, it can be hidden inside the door without affecting the overall beauty.

[0003] Publication No.: CN218347164U discloses a hinge structure, including a receiving box and a functional shaft disposed in the receiving box. The feature is that it further includes a connecting shaft. One end of the connecting shaft is connected to the functional shaft, and the other end is provided with a plurality of jacks along its circumferential direction for an external tool to be inserted to drive the connecting shaft to rotate. A notch for the external tool to enter and exit the receiving box is opened at a position corresponding to the jacks on the receiving box. With the above technical solution, the utility model provides a hinge structure that is convenient for the insertion of an external tool, and is convenient and fast when rotating the adjustment shaft, and is not easy to slip. However, this technology requires speed adjustment through tools, which has the problems of inconvenient speed adjustment and slow speed adjustment. When the hinge needs to be speed-adjusted, tools need to be found first to perform the speed adjustment. At the same time, using tools for speed adjustment is easy to collide with the hinge and cause wear to the hinge, reducing the service life of the hinge. Therefore, there is still room for improvement in this technology. Summary of the Invention
