In this embodiment, the inclined surface 4211 is disposed on the same side as the unlocking button 4231, and the limiting surface 4212 is disposed opposite to the unlocking button 4231, that is, when the upper expanding section 111 and the lower expanding section 121 are opened from the substantially closed state with respect to the pressing portion 13, the first locking position 411 slides relatively from the inclined surface 4211 of the second locking position 421, whereas if the upper expanding section 111 and the lower expanding section 121 are to be changed from the relatively opened state to the substantially closed state, the first locking position 411 interacts with the limiting surface 4212 of the second locking position 421, and the limiting surface 4212 has no relative sliding angle, so as to limit the first locking position 411. Therefore, through the matching arrangement of the inclined surface 4211 and the limiting surface 4212, the first locking position 411 only passes through the second locking position 421 from the inclined surface 4211 of the second locking position 421, but cannot pass through the second locking position 421 from the limiting surface 4212 of the second locking position 421, so that when a force is applied to the pressing part 13, the upper expansion section 111 and the lower expansion section 121 can be relatively opened, and after the force applied by the pressing part 13 disappears, the opening state of the upper expansion section 111 and the lower expansion section 121 can be still maintained, and the upper expansion section 111 and the lower expansion section 121 cannot be reversely closed, so that the upper expansion section 111 and the lower expansion section 121 are conveniently opened, and the state that the upper expansion section and the lower expansion section cannot be reversely closed is stably maintained, thereby forming a point that the inspection channel is conveniently opened, stably and stably maintained, and cannot be reversely reduced.

In this embodiment, when the upper dilator 1, the lower dilator 2 and the two side dilators 3 are all in the open state, that is, when the upper dilating segment 11, the lower dilating segment 21 and the two side dilating segments 31 are in the open state, the four form an examining channel, the cross sections of the four are located on the same circumference of a basic circle, and the cross section of the examining channel is approximately located on the same circumference of the basic circle, and the diameter of the basic circle gradually decreases from the direction away from the microscopic end to the direction close to the microscopic end, that is, from the direction away from the examining port 121 to the direction close to the examining port 121, that is, the cross section of the examining channel at the vaginal opening is smaller, and the section of the examination channel is gradually increased along with the extension towards the deep part of the vagina, so that the examination space inside the vagina is enlarged, so can be convenient for the doctor to carry out all-round inspection to vagina inside, avoid the inspection to omit, strengthened the accuracy of inspection. In addition, the end with the larger cross section of the examination channel formed by the upper expansion section 11, the lower expansion section 21 and the two side expansion sections 31 is positioned in the deep vagina, and the end with the smaller cross section of the examination channel formed by the upper expansion section, the lower expansion section 21 and the two side expansion sections 31 is positioned at the vaginal opening, so that the dilator is prevented from falling out in the detection process.
