The invention provides a furniture hinge comprising a stationary box body (11, 111), and the stationary box body is designed into a structure that the central part (21, 121) is contained in a hole (18, 118) of a piece of furniture. The box body comprises two pins (16, 17, 116, 117) which can axially rotate, and the rotatable pins are designed to be assembled in the hole (18, 118) together with the central part of the box body. Each pin (16, 17, 116, 117) has at least a transverse protruding tongue (19, 20, 119, 120). Working levers (14, 15, 114, 115) enable the pins to rotate, so as to lead the protruding tongues to outwards protrude from the box body, thereby interfering with the wall of a receiving hole, and preventing the box body from being drawn out from the hole.
