The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, including arc 1 that the nock is down, fixed slot 2 has been seted up on the arc 1, it has casing 3 to articulate in the fixed slot 2, link up about having seted up on casing 3 and open up U-shaped hole 4 forward, there is ratchet 5 of left and right sides direction respectively sliding connection in casing 3, the looks remote site of two ratchet 5 is equipped with splint 6 that is located U-shaped hole 4 respectively, but the casing 3 in the left and right sides be equipped with respectively the fore-and-aft swing and can with ratchet 5 meshed pawl 7, set up the waist groove 8 of left and right sides direction on the pawl 7, there is the pin 9 of fore-and-aft direction and being located the pawl 7 top left and right sides sliding connection respectively on casing 3, pin 9 rear end is equipped with the pull post 10 of axial about and inserting its corresponding side waist inslot 8, open-backward spacing groove 11 has been seted up respectively to the left and right sides on the fixed slot 2 preceding lateral wall, pin 9 front end can insert in spacing groove 11.

In order to enable the pawls 7 to swing back and forth, the opposite ends of the two pawls 7 are respectively hinged with the shell 3, the left side and the right side of the shell 3 are respectively provided with an arc-shaped groove 12 positioned above the pawls 7, the arc openings of the two arc-shaped grooves 12 are opposite, the upper end of each pawl 7 is provided with a pull hook 13 extending out of the arc-shaped groove 12, and the rear end of each pawl 7 is connected with the shell 3 through a pressure spring 14.

In order to facilitate the resetting of the splint 6, pull grooves 15 in the left and right directions are respectively formed in the left and right sides of the shell 3, pull rods 16 extending out of the pull grooves 15 in the up-down direction and the upper ends of the ratchet bars 5 are arranged on the ratchet bars 5, and the opposite ends of the two ratchet bars 5 are respectively connected with the shell 3 through tension springs 17.

In order to make the housing 3 rotatable, a torsion spring 18 is provided between the housing 3 and the fixing groove 2.

In order to prevent the arc plate 1 from turning over excessively, the left side and the right side of the rear end of the arc plate 1 are respectively provided with a baffle plate 19, and the baffle plates 19 can be in contact with the shell 3.

For the convenience of fixing the arc plate 1 and the mouth of the patient, the left end and the right end of the arc plate 1 are respectively provided with a binding belt 20, the lower surface of the left binding belt 20 is provided with a first magic tape 21, and the upper surface of the right binding belt 20 is provided with a second magic tape 22 which can be bonded with the first binding belt 20.

When the utility model is used, after the trachea cannula of a patient is finished, a medical staff places the free end of the trachea between two clamp plates 6 and extends out of a U-shaped hole 4, aligns the arc plate 1 with the mouth of the patient and fits with the skin on the face, enables the restraining belt 20 to cling to the neck of the patient and enables the first magic tape 21 to be bonded with the second magic tape 22, fixes the arc plate 1 with the mouth of the patient, at the moment, the medical staff pulls the pull rod 16 relatively, the pull rod 16 drives the ratchet bar 5 on the corresponding side to move, the two ratchet bars 5 move relatively, when the ratchet bars 5 move relatively, the ratchet bars 5 stretch the tension springs 17 on the corresponding side to enable the two tension springs 17 to have opposite tension, the ratchet bars 5 drive the clamp plates 6 on the corresponding side to move, the two clamp plates 6 move relatively and extrude the trachea, after moving for a certain distance continuously, the clamp plates 6 completely fix the trachea and then loosens the pull hook 13, at the moment, due to the forward elasticity of the pressure spring 14, the opposite ends of the two swing rods are driven to realize the matching with the ratchet racks 5 on the corresponding sides of the two swing rods again, so that the position of the clamping plate 6 is limited, and the trachea is prevented from falling off from the oral cavity of a patient;

when the two ratchet bars 5 move relatively, the pawls 7 on the corresponding sides of the ratchet bars are upwards extruded, after a certain angle of extrusion is achieved, the pawls 7 are disengaged from the ratchet bars 5, the limit on the clamping plate 6 is released, the pawls 7 swing backwards, and simultaneously the compression springs 14 are compressed backwards, so that the compression springs 14 have forward elasticity, after the ratchet bars 5 move for a certain distance, the pawls 7 are driven to swing forwards due to the forward elasticity of the compression springs 14, and after the pawls swing for a certain angle, the pawls are re-engaged with the ratchet bars 5 on the corresponding sides of the pawls, so that the limit on the ratchet bars 5 is achieved, and the clamping plate 6 is prevented from loosening to cause the trachea to fall off;

after the fixing for a period of time, when the oral cavity of the patient needs to be nursed, the medical staff pulls the pulling hook 13 backwards, the pulling hook 13 drives the pawl 7 on the corresponding side to swing backwards, after swinging for a certain angle, the opposite ends of the two pawls 7 are respectively separated from the matching with the ratchet bars 5 on the corresponding sides, the limiting on the splint 6 is released, at this time, due to the pulling force of the tension spring 17, the ratchet bars 5 drive the splint 6 to move, after moving for a certain distance, the splint 6 releases the fixing on the trachea, when the pawls 7 swing backwards, the pawls 7 drive the stop lever 9 to move backwards through the pull column 10 and leave the limiting groove 11, the fixing on the shell 3 is released, at this time, the shell 3 is driven to swing backwards due to the torsion of the torsion spring 18, after swinging for a certain angle, the upper end of the shell 3 contacts with the front end of the baffle plate 19, so as to prevent the shell 3 from turning over excessively, thereby affecting the use effect, at this time, the pulling hook 13 is released, the oral cavity of the patient can be nursed;

after the oral care of the patient is finished, the medical staff pulls the pull hook 13 backwards to drive the stop lever 9 to move backwards, after the oral care is finished for a certain distance, the front end of the stop lever 9 returns to the shell 3, the shell 3 swings forwards at the moment, the shell 3 returns to the initial position after swinging for a certain angle, the pull hook 13 is loosened at the moment, the stop lever 9 is driven to move forwards due to the forward elasticity of the pressure spring, after the stop lever 9 moves for a certain distance, the front end of the stop lever 9 is reinserted into the limiting groove to limit the shell, at the moment, the two pull rods 16 are pulled oppositely, the pull rods 16 drive the splint 6 to move through the ratchet 5 to fix the trachea, when the ratchet 5 moves, the pawl 7 is upwards extruded, after the pawl 7 is separated from being matched with the ratchet 5 after the extrusion for a certain distance, after the ratchet 5 continues to move for a certain distance, the pawl 7 is pressed by the pressure spring 14 to drive the pawl 7 to realize the matching with the ratchet 5 again, the clamping plate 6 is fixed;

after the patient no longer need fix trachea cannula, medical personnel detain backward and pull hook 13, pull hook 13 and drive pawl 7 swing backward, swing certain angle after, pawl 7 breaks away from the cooperation with ratchet 5, remove the spacing to splint 6, this moment because the pulling force of extension spring 17, ratchet 5 drives its splint 6 that corresponds the side and removes, two splint 6 move one section distance back on the back, remove tracheal fixed, make first magic subsides 21 and second magic subsides 22 break away from the bonding this moment, keep away from U-shaped hole 4 with trachea cannula and make arc 1 take off from patient's oral area can.
