[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] This invention utilizes an adjustment mechanism to rotate a threaded sleeve, leveraging its mirror-threaded connection with the first and second screws at both ends to precisely adjust the distance between the adjustment frame and the mounting plate. This makes the adjustment process intuitive and controllable, requiring only a simple rotation operation. Simultaneously, as the threaded sleeve rotates, the adjustment frame moves the limiting rod within the adjustment groove, thereby achieving precise adjustment of the hinge plate position. This adjustment method not only improves the hinge's adaptability, enabling it to accommodate doors and side panels of different sizes and shapes, but also greatly enhances the convenience of adjustment, simplifying the installation and maintenance process.
