when the sampling brush 320 needs to be replaced, the lower half part of the installation body 310 is pinched by a hand, then the installation body 310 is rotated, then the steel balls 430 on the connecting column 410 are separated from the clamping grooves 3111 on the connecting groove 311, then the installation body 310 is pulled upwards, further the installation body 310 is separated from the connecting column 410, further the installation body 310 is separated from the rotating disc 250, then a new installation body 310 is replaced, the connecting groove 311 on the installation body 310 is inserted into the connecting column 410, then the lower half part of the installation body 310 is pinched by a hand, the installation body 310 is rotated, further the clamping grooves 3111 on the installation body 310 rotate along with the installation body 310, when the clamping grooves 3111 are aligned with the steel balls 430 on the connecting column 410, the steel balls 430 are clamped into the clamping grooves 3111 under the elastic force of the elastic members 420, further the fixed connection between the installation body 310 and the connecting column;
can adjust the length of stretching out of sampling component 300 wantonly through above-mentioned device, facilitate the use, sampling component 300 is to retracting back to in the installation cover 110 after having got the appearance in addition, taking out from the vagina, taking out in-process installation cover 110 and keeping apart sampling brush 320 with the vagina, avoid the sample on the sampling brush 320 to lead to the sample to drop with the vagina wall friction, avoid other secretions in the vagina to pollute the sample simultaneously, play isolation, guard action simultaneously.
It should be noted that the specific model specifications of the motor 220 and the battery 230 need to be determined by model selection according to the actual specification of the device, and the specific model selection calculation method adopts the prior art, so detailed description is omitted.
The power supply of the motor 220 and the battery 230 and the principle thereof will be apparent to those skilled in the art and will not be described in detail herein.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
