A resistance block 34 is provided below the transmission shaft 32, and an inner circle is provided in the resistance block 34 (not shown in the figure). The transmission shaft 32 is slidably connected to the inner circle provided in the resistance block 34, and a spring 35 is provided below the resistance block 34. A fixing block 36 is provided below the spring 35, and the fixing block 36 is fixedly connected to the ring sleeve 39. A locking block 38 is slidably installed on the lower end of the ring sleeve 39, and a locking groove 381 is provided on the upper end of the locking block 38. The interior of the locking groove 381 is circular and the shape and size of its opening are consistent with the shape of the lock head 322. A limiting block 382 is provided at the lower end of the locking block 38, and the upper end of the limiting block 382 contacts the bottom end of the ring sleeve 39;

[0025] The lower end of the upper bracket 31 is provided with a second protrusion 312, and a second arc groove 311 is provided on the right side of the second protrusion 312. The second protrusion 312 is connected to the second arc groove 311 and is evenly distributed in four groups;

[0026] The lower end of the lower bracket 33 is provided with a first protrusion 332, and a first arc groove 331 is provided on the right side of the first protrusion 332. The first protrusion 332 is connected to the first arc groove 331 and is evenly distributed in four groups.

[0027] The upper bracket 31 and the lower bracket 33 slide up and down along the ring sleeve 39 via the sliding shaft 37, the transmission shaft 32 slides up and down along the empty groove inside the transmission block 313, the locking block 38 slides up and down along the ring sleeve 39, and the resistance block 34 slides up and down along the ring sleeve 39;

[0028] For ease of description, the mechanism has an initial state. In the initial state, the spring 35 is in an extended state, the abutment block 34 always abuts against the transmission shaft 32, and the abutment head 321 is always located in the empty slot between the upper bracket 31 and the lower bracket 33 and in the first arc slot 331.

[0029] When installing the hinge, first fix the left hinge 2 and the right hinge 1 in the specified position, splice the left hinge 2 and the right hinge 1 to leave a position for the rotating shaft 3, put the locking block 38 into the ring sleeve 39 installed inside the rotating shaft 3, until the upper surface of the limit block 382 contacts the lower surface of the ring sleeve 39, press the transmission block 313 to drive the upper bracket 31 and the lower bracket 33 to slide downward along the ring sleeve 39 through the sliding shaft 37, because the interference block 34 is slidably connected to the transmission shaft 32, the transmission shaft 32 slides through the inner circle of the interference block 34, and when the transmission block 313 is pressed down, the transmission shaft 32 is always downward under the influence of gravity until the interference head 321 always contacts the first arc groove 331, the transmission block 313 continues to press down, and the lower bracket 33 and the interference block 34 When the cam 35 is in the closed position, the spring 35 is pressed against the locking member 322 and the locking member 321 is pressed against the locking member 322. When the cam 35 is pressed against the locking member 322, the locking member 322 is pressed against the locking member 321. When the cam 35 is pressed against the locking member 322, the locking member 322 is pressed against the locking member 322 and the locking member 322 is pressed against the locking member 321.

[0030] When the hinge is disassembled, the transmission block 313 is pressed again, and the locking head 322 continues to move downward in the locking groove 381 until it contacts the bottom of the locking groove 381. The continued downward pressure of the transmission block 313 causes the contact head 321 to enter the first arc groove 331 along the inclined surface of the first protrusion 332 from the second arc groove 311. The transmission block 313 is released, and the spring 35 returns to its initial state, pushing the lower bracket 33 to move upward. The contact head 321 enters the second arc groove 311 along the inclined surface of the second protrusion 312 from the first arc groove 331. The locking head 322 turns ninety degrees and exits the notch on the locking groove 381. The locking block 38 is released and removed, and the left hinge 2 and the right hinge 1 of the hinge are completely disassembled.

[0031] To sum up, the hinge presses down the transmission block 313, so that the lock head 322 continues to move downward in the lock groove 381 and contacts the bottom of the lock groove 381, driving the contact head 321 to move in the empty groove left between the upper bracket 31 and the lower bracket 33, completing the tightening or withdrawal of the lock head 322 to the lock groove 381, and realizing the locking and opening of the lock block 38, making it easy to disassemble and install the left hinge 2 and the right hinge 1 of the hinge.
