[0030] One end of the connection strap 2 connected to the docking fixing mechanism is set as a Velcro, which is used to adjust according to the size of the patient's head so that the connection strap 2 fits the patient's head.

[0031] The two sets of fixing plates 18 of the docking fixing mechanism are connected to the connecting strap 2 on the outside, and are provided with a docking structure and an arc-shaped clamping pad 19 on the inside; the docking structure is used to dock the two sets of fixing plates 18; the arc-shaped clamping pad 19 is made of rubber, and the two arc-shaped clamping pads 19 can clamp the endotracheal tube after being combined to prevent it from slipping out of the patient's mouth. The docking structure of the two sets of fixing plates 18 is symmetrically arranged relative to the center of the endotracheal tube, and the docking structure includes an active docking unit and a passive docking unit, which are respectively arranged on both sides of the arc-shaped clamping pad 19 on the fixing plate; when the two sets of fixing plates 18 are docked, the active docking unit and the passive docking unit are engaged to achieve the docking of the two fixing plates 18.

[0032] The active docking unit includes a first semicircular plate 20 and a first lever 21. The first semicircular plate 20 is rotatably arranged inside the fixed plate 18, and a rotating track for the first semicircular plate 20 is arranged inside the fixed plate 18; the arc-shaped portion of the first semicircular plate 20 faces the side away from the arc-shaped clamping pad 19, one end of the first lever 21 is fixedly connected to the arc-shaped portion of the first semicircular plate 20, and the other end is arranged to extend out of the fixed plate 18.

[0033] The passive docking unit includes a second semi-circular plate 22 and a second lever 23; the second semi-circular plate 22 is rotatably arranged inside the fixing plate 18, and a rotating track for the second semi-circular plate 22 is arranged inside the fixing plate 18; the arc portion of the second semi-circular plate 22 faces the side close to the arc-shaped clamping pad 19; one end of the second lever 23 is fixedly connected to the arc portion of the second semi-circular plate 22, and the other end is connected to the inner wall of the fixing plate 18 through an elastic cord. When not docked, in the passive docking unit of the fixing plate 18 on one side, the elastic cord pulls one end of the second lever 23, causing a corner of the second semi-circular plate 22 to protrude from the fixing plate 18; during docking, the active docking unit and the passive docking unit are engaged, and the second semi-circular plate 22 is pushed to rotate when the fixing plate 18 moves. When it coincides with the first semi-circular plate 20, due to the action of the elastic cord, the second semi-circular plate 22 and the first semi-circular plate 20 rotate simultaneously, causing the second semi-circular plate 22 of the fixing plate 18 on one side to be embedded in the rotating track of the first semi-circular plate 20 of the fixing plate 18 on the other side, realizing the docking of the two fixing plates 18. When the two fixing plates 18 are separated, the first lever 21 protruding from the fixing plate 18 is toggled to make the second semi-circular plate 22 and the first semi-circular plate 20 rotate simultaneously, so that the two fixing plates 18 can be separated from each other.

[0034] A scale plate 24 for indicating the fine-tuning distance after the tracheal intubation is inserted is further arranged on the fixing plate 18, and one side of the scale plate 24 is fixedly connected to the side of the arc-shaped clamping pad 19 on the fixing plate 18; after the tracheal intubation is inserted, medical staff still need to fine-tune the insertion depth according to the specific situation of the patient and the tracheal intubation. The scale plate 24 is provided with a fine-tuning distance of 0-15 mm, and medical staff can perform fine-tuning according to the indication of the scale plate.

[0035] When the present invention is in use, medical staff move the patient's head and place it on the elastic band 3 above the bottom plate 1. After the patient undergoes tracheal intubation, medical staff unlock the clamping plates 4 by toggling the triangular drives 8 of the two groups of clamping plates 4, so that the clamping plates 4 fix the patient's head, and move the two fixing plates 18 to dock and fix the tracheal intubation from both sides of the tracheal intubation. Then, by adjusting the connecting strap 2, the connecting strap 2 is made to fit the patient's head. When removing the fixator, medical staff toggle the two first levers 21 to separate the two fixing plates 18 from each other, loosen the tracheal intubation, and toggle the triangular drives 8 of the two groups of clamping plates 4 to unlock the clamping plates 4, so that the clamping plates 4 move away from both sides of the patient's head, and the fixator can be detached.
