The two limiting parts 114 on the upper expanding piece 11 act on the two side expanding pieces 13 respectively, so that the opening or closing of the side expanding pieces 13 is realized, the expansion linkage between the upper expanding piece 11 and the side expanding pieces 13 is realized by a simple structure, and the structure is simple and the stability is high. Specifically, the two limiting portions 114 are disposed along the side of the pressing portion 113, the side of the pressing portion 113 is the side when the pressing portion 113 cooperates with the transition plate 1123 and the two side plates 1124 to form the inspection opening 1121, the two limiting portions 114 are disposed on the surface of the pressing portion 113 facing the connecting plate 1231, one end of each of the two limiting portions 114 is close to the inner wall of the corresponding side plate 1124, and the other ends of the two limiting portions 114 extend in opposite directions.

When a force is applied to the pressing portion 113, in the process of driving the upper expansion section 111 and the lower expansion section 121 to open relatively, the pressing portion 113 acts on the limiting arc ends 1331 of the two sliding portions 133 through the two limiting portions 114 synchronously, so that the two sliding portions 133 slide on the two limiting portions 114 respectively in the opposite directions, and thus the two side expansion sections 131 are driven to open relatively, whereas, in the process of closing the upper expansion section 111 and the lower expansion section 121 relatively, the limiting arc ends 1331 of the two sliding portions 133 slide on the two limiting portions 114 respectively in the opposite directions, and the two side expansion sections 131 are closed relatively. The limiting portion 114 in this embodiment may be a sliding block. Preferably, an escape position 1143 is provided between the two stopper portions 114.

The avoidance space 1143 in this embodiment is specifically a U-shaped notch formed between the two limiting portions 114. Preferably, the stopper 114 is inclined from the outside of the inspection passage to the inside of the inspection passage. In the present embodiment, the stopper 114 is inclined from the outer side of the inspection hole 1121 toward the inner side of the inspection hole 1121. Thus, by the inclined arrangement of the limiting portions 114 from outside to inside, when the pressing portion 113 applies a force, the upper expanding section 111 and the lower expanding section 121 are driven to open relatively, so that the sliding motion of the limiting arc ends 1331 of the two sliding portions 133 synchronously acted by the two limiting portions 114 is smoother. In a specific application, the specific inclination angle of the limiting portion 114 may be set according to actual conditions, and the inclination angle of the limiting portion 114 from the outer side of the inspection hole 1121 to the inner side of the inspection hole 1121 is within 5 degrees.

The second surface 1142 is slidably connected to the limiting arc-shaped end 1331 of the sliding part 133. In this embodiment, the first end 11421 is an end of the second surface 1142 close to the integral connection between the position-limiting portion 114 and the side plate 1124, and the second end 11422 is another end of the second surface 1142 away from the integral connection between the position-limiting portion 114 and the side plate 1124. It can be understood that when a force is applied to the pressing portion 113, during the process of bringing the upper expansion section 111 and the lower expansion section 121 to open relatively, the second surface 1142 of the position-limiting portion 114 is in sliding contact with the position-limiting arc-shaped end 1331 of the sliding portion 133, and the second surface 1142 continuously acts on the position-limiting arc-shaped end 1331 of the sliding portion 133, so that the two side expansion sections 131 open relatively to form the examination channel, and during the formation of the examination channel, the vagina does not contract spontaneously and acts on the upper expansion section 111, the lower expansion section 121, and the two side expansion sections 131 in reverse, which causes the side expansion sections 131 to act on the two position-limiting arc-shaped ends 1331 in reverse, so that the two position-limiting arc-shaped ends 1331 have a tendency to slide in reverse, and in practical use, after the second surface 1142 is limited to extend from the first end 11421 to the second end 11422, and the second surface 1142 gradually approaches the first surface 1141, the degree of action of the second surface 1142 on the position-limiting arc-shaped end 1331 gradually increases, thereby limit spacing arc end 1331 reverse slip trend, and along with the in-process that second face 1142 drawn close gradually towards first face 1141, second face 1142 can increase gradually spacing arc end 1331 restriction angle, can be increasingly strong to the restriction of spacing arc end 1331 reverse slip trend, so not only can make two side expansion section 131 open the process smoothness, still can strengthen spacing portion 114 to the restriction degree of spacing arc end 1331 gradually, in order to counter the vagina contraction reverse action, thereby can avoid spacing arc end 1331 to appear reverse slip, the process smoothness of opening of upper expansion section 111, lower expansion section 121 and two side expansion section 131 has been guaranteed, can open formation inspection channel smoothly.

EXAMPLE six

The difference between the vaginal dilator in this embodiment and the second embodiment is that: when the upper expanding section 111 and the lower expanding section 121 are in the substantially closed state, the cross sections of the two sections are located on the same substantially circular circumference, and the diameter of the substantially circular shape is gradually increased from the direction away from the inspection hole 1121 to the direction close to the inspection hole 1121. It can be understood that when the expansion module 1 in the substantially closed state enters the vagina, the vagina needs to have a gradual receiving process, otherwise discomfort of a patient can be caused, and by defining the direction from the position far away from the examination opening 1121 to the position close to the examination opening 1121, the diameter of the substantially circular shape is gradually increased, so that when a doctor uses the expansion module 1 to enter the vagina, the doctor firstly enters the end, with the smaller diameter, of the substantially circular shape formed by matching the upper expansion section 111 and the lower expansion section 121, and then gradually increases the diameter of the substantially circular shape, discomfort of the patient can be reduced, and the discomfort of the patient can be more smooth.
