Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Based on the description in the background art, it can be known that, after the existing sampling device such as cervical brush is provided with the shell 100, the inner wall of the shell 100 and the sampling member 200 generally do not have a connection structure, thereby avoiding affecting the movement of the sampling member 200, which makes the sampling member 200 not obtain good spacing in the shell 100, and the stability of the sampling member 200 in the sampling process is poor.

Referring first to fig. 1, 2 and 3, the sampling device with a housing provided in the present embodiment includes a housing 100 and a sampling member 200 inserted in the housing 100; the sampling member 200 of the present embodiment includes a sampling head 210, a rod 220 and an operating handle 230, which are connected in sequence, and the sampling head 210 and the rod 220 of the present embodiment may be integrally connected or integrally formed.

Different from the existing structure, the present embodiment has a fixing hole 121 in the housing 100, the fixing hole 121 has a certain axial width (i.e. left and right direction in fig. 3), and as shown in fig. 4, the middle portion of the rod 220 of the present embodiment is provided with a spiral part 221, the structural form of the spiral part 221 can refer to the screw structure on the bamboo dragonfly, the length of the spiral part 221 enables the sampling head 210 to complete the expansion and contraction with respect to the housing 100, and the preferred spiral part 221 can be lengthened according to the specific requirement, the radial dimension of the spiral part 221 of the present embodiment is larger than the radial dimension of the rod 220, the spiral part 221 is inserted in the fixing hole 121, and screwing the operating handle 230 of the present embodiment can move the spiral part 221 along the axial direction of the housing 100, so as to extend or retract the sampling head 210 into the housing 100 of the present embodiment.

Realize the spacing of sampling component 200 in radial ascending fixedly through the cooperation of spiral portion 221 and fixed orifices 121 to utilize the characteristic of spiral portion 221 internal rotation removal in fixed orifices 121 to realize the extension or the withdrawal of sampling head 210 for shell 100, not only simple structure does benefit to the operation, can improve the stability of sampling head 210 among the sampling process moreover, and then improve the security of sampling efficiency and the sampling process.

Referring to fig. 3 and 6, in order to prevent the spiral part 221 from falling off the fixing hole 121 of this embodiment to the right, in this embodiment, a first position-limiting ring 2211 is disposed at one end (the left end in fig. 3) of the spiral part 221 close to the sampling head 210, and the radial dimension of the outer wall of the first position-limiting ring 2211 of this embodiment is greater than the radial dimension of the fixing hole 121 of this embodiment, so that when the spiral part 221 moves to the right, the first position-limiting ring 2211 and the fixing hole 121 can be in position-limiting fit, and the spiral part 221 is prevented from falling off the fixing hole 121.

In order to insert the rod 220 of this embodiment, the radial dimension of the end (right end in fig. 3) of the spiral part 221 away from the sampling head 210 is smaller than the radial dimension of the fixing hole 121, so that the spiral part 221 can be inserted into the fixing hole 121 of this embodiment conveniently.

Referring to fig. 3 and 5, in order to achieve the automatic retraction of the sampling head 210 after extending out of the housing 100, in this embodiment, a second position-limiting ring 111 is disposed at one end of the housing 100 close to the sampling head 210, and in order to prevent the second position-limiting ring 111 from affecting the extension or retraction of the sampling head 210, the aperture of a position-limiting hole formed by the second position-limiting ring 111 of this embodiment is larger than the radial dimension of the sampling head 210.

In addition, the inventor finds that the sampling head 210 of the existing sampling device with a housing cannot automatically retract after being extended, and needs to be manually operated again, which is very inconvenient, therefore, based on the first and second limiting

rings

2211 and 111, the embodiment further installs a return spring 300 in the housing 100, one end of the return spring 300 is connected to the first limiting ring 2211, the connection mode can be an abutting or fixed connection mode, and the other end is connected to the second limiting ring 111, the connection mode can be an abutting or fixed connection mode, when the sampling head 210 extends out of the housing 100, the return spring 300 is compressed, when the operator releases the operating handle 230, the elastic force of the return spring 300 drives the rod 220 of the embodiment to move, so that the sampling head 210 retracts into the housing 100, and the collected cervical secretions and secretions in the vagina are prevented from mixing, ensuring the accuracy of subsequent pathological detection. In addition, the elastic member of the present embodiment connects the housing 100 and the spiral part 221, respectively, thereby further enhancing the effect of limiting and fixing the whole sampling member 200 of the present embodiment.

In addition, in order to prevent the fixing hole 121 and the spiral part 221 from being fitted too tightly and affecting the rotation and movement of the spiral part 221, the spiral part 221 and the fixing hole 121 are fitted with a gap, preferably smaller than 1mm, in the present embodiment, and in order to facilitate the rotation of the spiral part 221, the fixing hole 121 is designed to have an elliptical shape.
