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

By figure 1 to 4, including the fixed box 1 of left and right directions, the left and right sides articulates respectively has the pendulum rod 2 of upper and lower direction in the fixed box 1, two pendulum rods 2 can be relative or back of the body swing mutually, be equipped with the shape frame 3 that returns that is located between two pendulum rods 2 and left and right directions in the fixed box 1, both ends run through fixed box 1 respectively around returning shape frame 3, it has front and back axial and curved clamp plate 4 to return the shape frame 3 in left and right sides sliding connection respectively, two clamp plate 4 openings are relative, the end of backing mutually of two clamp plate 4 is equipped with the push rod 5 of left and right directions respectively, two push rod 5 back of the body end run through respectively back shape frame 3 and with return shape frame 3 sliding connection, the end of backing mutually of two push rods 5 respectively with its pendulum rod 2 contact that corresponds the side, fixed box 1 rear end is equipped with return shape frame 3 intercommunication and front and back direction.

In order to enable the two swing rods 2 to swing oppositely or oppositely, a pull rod 7 which is positioned right above the square frame 3 and can move up and down is arranged in the fixed box 1, and the left end and the right end of the pull rod 7 are respectively hinged with the free ends of the swing rods 2 on the corresponding sides through connecting rods 8.

In order to move the pull rod 7 up and down, the upper side of the pull rod 7 is rotatably connected with a screw rod 9 in the vertical axial direction, the screw rod 9 is in threaded connection with the fixed box 1, and the upper end of the screw rod 9 penetrates through the fixed box 1 and is coaxially provided with a knob 10.

In order to make the two clamping plates 4 slide left and right, the two push rods 5 are respectively sleeved with a tension spring 11 positioned between the corresponding clamping plate 4 and the clip frame 3.

For the convenience of fixing this device, fixed box 1 left and right sides be equipped with fixed band 12 respectively, be equipped with the female subsides 13 of magic on the surface of the 12 free ends of left fixed band, be equipped with on the internal surface of the 12 free ends of fixed band on right side and paste 14 with the female sticky magic that 13 is glued of magic.

In order to increase the friction, the opposite ends of the two clamping plates 4 are provided with rubber pads 15, respectively.

When the utility model is used, the initial state of the device is that the lower end surface of the pull rod 7 is contacted with the upper end surface of the clip frame 3, and the two tension springs 11 are in normal state;

after a tracheal catheter is inserted into the oral cavity of a patient, inserting the free end of the tracheal catheter into the fixed tube 6, extending the free end of the tracheal catheter out of the square frame 3, positioning the tracheal catheter between the two clamping plates 4, inserting the fixed tube 6 into the mouth of the patient, enabling the patient to bite the fixed tube 6 with teeth to prevent the patient from biting the tracheal catheter, rotating the knob 10 clockwise, driving the screw 9 to rotate clockwise by the knob 10, driving the knob 10 and the pull rod 7 to move upwards by the screw 9, driving the two swing rods 2 to swing relatively by the pull rod 7 through the connecting rod 8, driving the two push rods 5 to move relatively by the two swing rods 2, driving the two clamping plates 4 to move relatively and stretching the tension springs 11 on the corresponding sides of the two clamping plates 4, driving the two rubber pads 15 to move relatively by the two clamping plates 4, and gradually enabling the opposite surfaces of the two rubber pads 15 to be close;
