s1, when the box is used, the motor is controlled to drive the gear to rotate anticlockwise, so that the rack moves to the rightmost end of the sliding groove, at the moment, the right end of the limiting part is flush with the right side wall of the box body, namely, the leftmost end of the separating part is flush with the right side wall of the box body;
s2, placing a plurality of tongue depressors into the box body, wherein the top ends of the tongue depressors positioned at the top are supported on the bottom end surface of the limiting part under the elastic force of the top plate spring to complete the installation of the tongue depressors;
s3, the shell is stretched into the mouth of a patient, the motor is controlled to drive the gear to rotate clockwise, the rack moves rightwards, the separating part separates the upper and lower adjacent and close-fitting tongue depressors, and the uppermost tongue depressor enters the notch and moves rightwards along with the rack; meanwhile, the wedge block also moves along with the rack, in the moving process, the wedge block can be contacted with the extrusion wheel, the upper top plate rotates around a hinge point, the return spring is stretched, the angle between the upper top plate and the lower top plate is increased and acts on the upper tooth and the lower tooth respectively, and the mouth is expanded and the opening degree is kept; at the moment, the tongue depressor extends out of the chute to complete the pressing of the tongue;
s4, after throat examination is finished, controlling the motor to rotate anticlockwise to enable the rack to move rightwards; when the rack moves rightwards, the tongue depressor cannot move rightwards along with the rack and is left outside the shell, and a worker takes down the tongue depressor; when the rack moves, the upper top plate rotates to the initial state under the action of the elastic force of the return spring; along with the movement of the rack, the rack returns to an initial state, the next tongue depressor is supported at the bottom end of the limiting part under the action of the top plate spring, the automatic replacement of the tongue depressor is completed, and at the moment, one-time inspection is completed;
and S5, repeating the steps S1-S4 to finish the next throat check.
