The number of the first adjusting rod 32, the second adjusting rod 33 and the connecting shaft 34 is two. A groove 31 is provided on one side of the front and rear ends of the door frame 1. The two first adjusting rods 32 and the second adjusting rod 33 are rotatably arranged in the groove 31 through the connecting shaft 34. The adjusting mechanism 3 can make the fire door body 2 rotate to any angle in the door frame 1, thereby adjusting the opening and closing angle thereof, so that people can enter and exit in an orderly manner. The first adjusting rod 32 and the second adjusting rod 33 cooperate with each other to rotate to adjust the opening and closing angle of the fire door body 2, and the first adjusting rod 32 rotates on the first rotating post 35 and the second adjusting rod 33 rotates on the second rotating post 36, so that the rotation angle of the fire door body 2 is limited, thereby avoiding excessive angle adjustment and affecting people entering and exiting, thereby improving the practicality of the fire door. A first rotating post 35 is fixedly provided inside the door frame 1 and located in the corresponding groove 31. The ends of the two first adjusting rods 32 away from the connecting shaft 34 are rotatably set on the first rotating post 35. By rotating the ends of the first adjusting rod 32 away from the connecting shaft 34 on the first rotating post 35, the rotation angle of the first adjusting rod 32 can be limited. Second rotating posts 36 are fixedly provided on both sides of the upper end of the fire door body 2. The ends of the two second adjusting rods 33 away from the connecting shaft 34 are rotatably set on the second rotating post 36. By rotating the ends of the second adjusting rods 33 away from the connecting shaft 34 on the second rotating post 36, the second adjusting rod 33 can be affected by the first adjusting rod 32 to limit the rotation angle of the fire door body 2. A support rod 37 is fixedly provided on the inner side of the door frame 1, and a rotating hole 38 is opened in the middle part of the fire door body 2. The fire door body 2 is rotatably set inside the door frame 1 through the rotating hole 38.
