The specific manner in which screws can be used to penetrate the right through hole 2124 and screw into the right spiral hole 2112 is: the two right through holes 2124 are the right stair holes of the inward concave groove, and the right stair hole is the stair screw. It is inserted into the head of (24), and the stair screw 24 is movably connected with the right stair hole and forms a coupling structure for axial synchronization movement, and the stair screw 24 penetrates the right stair hole and forms a right helix Threaded into hole 2112.

Further, the specific manner in which a screw can be used to penetrate the left through hole 1124 and screw into the left spiral hole 1112 is: the two left through holes 1124 are the left stair holes of the inward concave groove, and the left stair hole The hole is inserted into the head of the stair screw 24, and the stair screw 24 is movably connected to the left stair hole and forms an axial synchronization coupling structure, and the stair screw 24 penetrates the right stair hole, threaded to the left threaded hole 1112;

The specific manner in which screws can be used to penetrate right through holes 2124 and threadedly connect to right threaded holes 2112 is: the two right through holes 2124 are the right stair holes of the long inward concave groove, and the screw 14 is used to pass through the right stair hole and spirally connect the right spiral hole 2112, and the right support frame 212 has a cavity of the right outer housing 211 and a gap in the longitudinal direction, so that the right outer housing 211 ) is accommodated in the cavity of

In the above embodiment, the left installation board and the right installation board may be fixedly connected to the door frame or the door leaf through screws. The hinge has a function that can be adjusted up and down, left and right, and can be installed in a mirror image, the left housing can be installed with a left and right movement function, the right housing can be installed with a vertical movement function, or the right housing can be installed with a left and right movement function. installed, and the left housing can be installed with a vertical movement function. In summary, on the one hand, it is installed in the housing as a vertical movement function, and on the other hand, it may have a left and right movement function. As described above, for example, the left stair hole is an elongated inward concave cavity, and the left large supporting frame is accommodated in the cavity of the left outer housing in such a way that there is a gap in the longitudinal direction with the cavity of the left outer housing. , This means that the left large supporting frame can move longitudinally with the cavity of the left outer housing, and the screw can still be screwed into the left stair hole, and the left stair hole inward concave groove allows the screw head to go into the left stair hole. It means that it can penetrate downward, and it does not need to be exposed, on the one hand it has a beautiful appearance, and on the other hand, the elongation of the screw head does not affect the smoothness of opening and closing of both housings and the gap after closing of both housings. don't Unscrewing can move the relative position of the left outer housing relative to the left large support frame, when the left outer housing is higher than the right outer housing in the longitudinal direction, the door leaf interconnected with the left outer housing rises in the vertical direction, and the left outer housing is higher than the right outer housing in the longitudinal direction.
