elastic force of the first spring 40, the, the limiting roller 30 can only be pushed forwards to leave the through cavity 28, when the body temperature of a user is normal, the signal lamp 55 is triggered to emit green light for a period of time, the stepping motor 69 works to drive the power shaft 67 and the second half gear 68 to rotate anticlockwise for a circle, the second half gear 68 rotates to drive the sliding toothed plate 57 and the third limiting pin 63 to move left, the second spring 56 is compressed, the third limiting pin 63 moves left to be separated from the third clamping groove 62 to remove the rotation limitation of the limiting wheel 61, the first clamping groove 64 moves left to a certain position, the first limiting pin 73 moves downwards under the elastic force of the third spring 71 to be clamped in the first clamping groove 64, so that the right movement of the sliding toothed plate 57 is limited, the second pull rope 49 is just in a tensioned state, the first stretching 59 still has a certain looseness, at the moment, the user pushes the limiting plate 27, the sixth rotating shaft 66, the limiting wheel 61 and the wire wheel 60 to rotate anticlockwise, and a channel of the through cavity 28 which the user moves backwards, the torsion spring between the sixth rotating shaft 66 and the lower inner wall of the second limiting cavity 65 and the upper inner wall of the open/close cavity 37 accumulates elastic potential energy, the sixth rotating shaft 66 rotates to wind the first tension 59 on the wire wheel 60, the first tension 59 is tensioned to drive the first sliding plate 72 to move upwards, the first sliding plate 72 moves upwards to drive the first limiting pin 73 to move upwards, the third spring 71 compresses, the first limiting pin 73 moves upwards to be separated from the first clamping groove 64, the right movement limitation of the sliding tooth plate 57 is released, the sliding tooth plate 57 moves right under the elastic force of the second spring 56, the third limiting pin 63 moves right to abut against the limiting wheel 61, when the user moves backwards, the third limiting plate 27 rotates clockwise to reset under the elastic force of the torsion spring between the sixth rotating shaft 66 and the lower inner wall of the second limiting cavity 65 and the upper inner wall of the open/close cavity 37, and when the limiting wheel 61 returns to the initial position, the third limiting pin 63 is re-clamped into the third clamping groove 62 to limit the rotation of the sixth rotating shaft 66, so that the limiting plate 27 cannot be pushed and the backward passage of the passage chamber 28 is closed again;

when the user is in the normal body temperature state, if the user does not push the limiting plate 27 to leave, in order to avoid the situation that the normal body temperature person is in the abnormal body temperature state, when the user with the normal body temperature moves forwards to push the limiting roller 30 to leave, the one-way wheel 17 and the first rotating shaft 18 rotate clockwise for one third of a circle along the same transmission route, the sliding tooth 16 in the right one-way wheel 17 rotates to drive the second straight gear 21, the cam 19 and the seventh rotating shaft 22 to rotate exactly for one circle, the cam 19 rotates to abut against the contact plate 20, the sliding rod 31 and the third sliding plate 32 to do reciprocating motion up and down under the elastic force of the sixth spring 35, when the third sliding plate 32 moves upwards, the second pull rope 49 is pulled, the second pull rope 49 is tensioned to drive the first sliding plate 72 to move upwards, the first sliding plate 72 moves upwards to drive the first limiting pin 73 to move upwards to separate from the sliding toothed plate 57, so that the sliding toothed plate 57 is reset under, the third stopper pin 63 is locked in the third locking groove 62 again to restrict the rotation of the sixth rotation shaft 66, and at this time, the rotation of the restriction plate 27 is restricted again, so that even if the user with normal body temperature moves forward and leaves, the user with abnormal body temperature cannot push the restriction plate 27 to move backward and leave.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
