A hinge base (A1) and a hinge. The hinge comprises a hinge body (B1) installed on a door plate (B) and the hinge base (A1) mounted on a door frame (A). The hinge base (A1) comprises a fixed plate (1), an eccentric cam, (4) and a base body (20) movably connected to the fixed plate (1). A first round convex body (42) of the eccentric cam (4) is fixed on the base body (20). A second round convex body (41) of the eccentric cam (4) penetrates the fixed plate (1) and is used to drive the base body (20) to move on the fixed plate (1) under the action of external torsion. The fixed plate (1) and the base body (20) are connected by means of the eccentric cam (4). During installation, only the fixed plate (1) needs to be installed on the door frame (A), and the base body (20) is connected to the hinge body (B1), which thereby achieves quick installation. Moreover, the eccentric cam (4) may adjust the base body (20), and under the action of external torsion, drive the base body (20) to move on the fixed plate (1), thereby adjusting the hinge base (A1) installed on the door frame (A) and the hinge body (B1) installed on the door plate (B) to facilitate the alignment and adjustment of the door frame (A) and the door plate (B).
