There is a self-locking mechanism 3 which cooperates with locking teeth 16 .

The preferred but not absolutely limited structure of the aforesaid self-locking mechanism 3 is as follows: comprise a pair of pin shaft seats 31, a pin shaft 32, a ratchet plate 33 and a torsion spring 34, and a pair of pin shaft seats 31 are directly formed on the On the front side wall of the middle part of the rear duckbill seat 2, the middle part of the ratchet plate 33 corresponds to between a pair of bearing pin seats 31. The left end of the ratchet plate 33 forms a ratchet 331, and the right end forms a finger pressing plate. 332, the pin shaft 32 passes through the shaft hole 311 on a pair of pin shaft seats 31 and the pin shaft hole 333 on the pawl plate 33, the torsion spring 34 is sleeved on the pin shaft 32, the first torsion spring of the torsion spring 34 The foot 341 is against the pawl 331 , and the second torsion spring foot 342 of the torsion spring 34 is positioned on the rear duckbill seat 2 .

As shown in Figure 1, on the aforementioned rear duckbill seat 2 and at the position corresponding to the second torsion spring foot 342 of the torsion spring 34, a torsion spring foot socket 25 is offered, and the end of the second torsion spring foot 342 is inserted into the torsion spring foot. In the spring pin jack 25.

What the applicant needs to explain is: if the aforementioned locking teeth 16 are transferred to the rear side wall of the middle part of the front duckbill seat 1, and the self-locking mechanism 3 is transferred to the rear side wall of the middle part of the rear duckbill seat 2 at the same time, Then it should be regarded as an equivalent replacement and still belongs to the scope of the technical content disclosed by the utility model.

Application example 1:

Please refer to Fig. 2, Fig. 2 shows the state that the front duckbill 11 and the rear duckbill 21 are closed, at this moment, a pair of guide plates 14 in the middle of the front duckbill seat 1 are in the state of leaving the guide plate cavity 23 (also called in the free state), while the position of the shaft head 22 on the shaft head matching groove 131 is at the left end of the shaft head matching groove 131, the aforementioned self-locking mechanism 3 releases the cooperation with the locking tooth 16, and in this state, the front, The rear duckbills 11, 21 are inserted into the examinee's vagina at the same time. When the front and rear duckbills 11, 21 are inserted deep into the vagina, when the aforesaid wings 26 are in contact with the labia majora, they prevent the The rear duckbills 11 and 21 are then inserted deep into the vagina so as not to damage the uterus.

Application example 2:

Please refer to Fig. 3, when the front and rear duckbills 11, 21 in the state shown in Fig. 2 are located in the vagina, the medical personnel only need to use their fingers (usually thumbs) to apply thrust to the push plate cavity 151 to make the front duckbill seat 11 is displaced to the left, and the front duckbill 11 is in the state of repelling the rear duckbill 21, so that the vagina is expanded. At this time, the pair of guide plates 14 correspond to the guide plate guide grooves 231, and are limited by the pair of guide plates 14. Flange 141 cooperates with the bottom wall on both sides of guide plate guide groove 231 and locks on duckbill seat 1, and simultaneously axle nose 22 matches with a axle nose matching groove of the rightmost end of a group of axle nose matching grooves 131, and by free The pawl 331 on the pawl plate 33 of the locking mechanism 3 locks the locking teeth 16 . In this state, it shows that the front duckbill 11 is at the maximum opening position, and the medical personnel can observe the situation in the vagina through the peeping cavity 12 . When the front and rear duckbills 11 and 21 are to be withdrawn from the vagina, one only needs to gently press the finger plate 332 of the ratchet plate 33 of the self-locking mechanism 3 so that the ratchet 331 is released from the engagement with the locking teeth 16, and the The front duckbill seat 1 is shifted to the right, so that a pair of guide plates 14 withdraw from the guide plate guide groove 231, that is, the lock is released.

In summary, the technical solution provided by the utility model overcomes the deficiencies in the prior art, completes the invention task, and objectively embodies the technical effect described by the applicant in the above technical effect column, which is an ultimate achievement.
