[0025] In a preferred embodiment, the bottom of the connecting block 2 is movably connected to a first fixed point 201, a first mounting hole 202 is opened on the front side of one side of the connecting block 2, the inner surface of the first mounting hole 202 is movably connected to a movable shaft 203, and the outer surface of the movable shaft 203 is movably connected to the first mounting hole 202 and the first connecting rod 204.
[0026] In a preferred embodiment, a second mounting hole 302 is opened on the other side of the second connecting rod 3, the inner surface of the second mounting hole 302 is movably connected to the first connecting pin 301, and the outer surface of the connecting pin 301 is movably connected to the first connecting rod 204 and the second connecting rod 3 respectively.
[0027] In a preferred embodiment, the inner surface of the second slide groove 305 is movably connected to a round rod 4, the outer surface of the round rod 4 is fixedly connected to a driving rod 401, a retaining spring 402 is movably connected between the driving rod 401 and the push-pull block 404, and the bottom of the push-pull block 404 is fixedly connected to a second fixed point 403.
[0028] In a preferred embodiment, the bottom of the retaining spring 402 is movably connected to the outer frame 1 .
[0029] In a preferred embodiment, a straight groove 101 is provided on the front of the first slide groove 303 , and a concave groove 102 is provided on the front of the second slide groove 305 .
[0030] In a preferred embodiment, the outer surface of the round rod 4 is movably connected with a recessed groove 102 and a second sliding groove 305 .
[0031] The working principle of the utility model is as follows: when using the hinge, bolts are used to pass through the holes on the connecting block 2 and fix it to the door frame. When the cabinet door is opened, the connecting block 2 is folded outward with the first fixed point 201 as the origin. At this time, the first connecting rod 204 is dragged to one side by the setting of the movable shaft 203 and the cam on one side of the bottom of the connecting block 2. Since the connecting pin 301 connects the first connecting rod 204 and the second connecting rod 3, when the connecting block 2 is folded, the first connecting rod 204 and the second connecting rod 3 move in the outer frame 1, and when the second connecting rod 3 is When the connecting rod 3 moves, the round rod 4 moves to the bottom of the second slide groove 305 and the recessed groove 102. At this time, the push-pull block 404 is folded outward with the second fixed point 403 as the origin. When the cabinet door is closed, the connecting block 2 and the outer frame 1 are at a ninety-degree angle. At this time, the round rod 4 is affected by the second connecting rod 3 and flips over the raised block 304 to move to the first slide groove 303. The setting of the raised block 304 can limit the driving rod 401 from moving for the second time. At this time, the retaining spring 402 works to make the push-pull block 404 expand outward with the second fixed point 403 as the origin.
