For example, a circuit board that is easy to disassemble as recorded in publication number CN218277276U relates to the technical field of circuit boards, including a board body, a movable ring is arranged at one end of the board body, and a second slider is connected to the outer wall of the movable ring, a second reserved groove is opened on the inner wall of one end of the board body, and a first reserved groove is opened on the inner wall of the other end of the board body, and a fastening component is installed on the other end of the board body;

[0003] In the above scheme, people can quickly complete the disassembly of the circuit board by disassembling the two bolts threadedly connected to the connecting ring, but it is still necessary to rotate the threaded assembly, which makes disassembly inconvenient, and the installation structure lacks position adjustment, resulting in the position of the installation structure itself being relatively fixed, resulting in the specifications of the replaced new circuit board must be consistent with the original circuit board before it can be replaced after disassembly, resulting in low adaptability of the installation structure.
