[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] It is found through research that, since the sampling forceps need to be deeply inserted into the human body for sampling when in use, and the sample needs to be kept in the closed state of the forceps to grasp the sample after being obtained, if the medical staff loses the sample in the middle of the operation, the forceps will be opened, which may lose the sample and increase the risk and uncertainty of the operation.

[0042] The above-mentioned defects are the results of the inventors' practice and careful research, and thus the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contributions of the inventors to the present disclosure.

[0043] Some embodiments of the present application will be described in detail with reference to the drawings below. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components can be exaggerated or reduced.

[0044] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, and thus once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0045] Based on the above research, the present disclosure provides a locking structure for a cable, referring to Figure 2 which comprises a positioning sleeve 1 and a matching sleeve 2 arranged separately, both the positioning sleeve 1 and the matching sleeve 2 are half-bowl-shaped, and the opening sides of the positioning sleeve 1 and the matching sleeve 2 are arranged oppositely, and the positioning sleeve 1 is rotationally connected with the matching sleeve 2. That is, in use, the cable can be positioned by the positioning sleeve 1, and at the same time, the matching sleeve 2 can be rotated. Further, the matching sleeve 2 has a plurality of locking partitions 21, which are distributed equidistantly along the axial direction of the matching sleeve 2. When the matching sleeve 2 is rotated, the locking partitions 21 can be clamped with a sampling tongs, thereby achieving the effect of positioning the matching sleeve 2. Since the positioning sleeve 1 and the matching sleeve 2 are assembled, after the matching sleeve 2 is positioned, the positioning sleeve 1 can be positioned, thereby achieving the effect of positioning the positioning sleeve 1 and the cable.

[0046] Referring to Figure 4 In at least one embodiment, in order to realize the function of the positioning sleeve 1 positioning the cable, the inner side of the positioning sleeve 1 is provided with a positioning block 12 along the axial direction, and at least one positioning groove 13 is formed in the axial direction of the positioning block 12. When two positioning sleeves 1 are provided, the planar sides of the two positioning sleeves 1 are spliced with each other, so that the two positioning blocks 12 are folded and the two positioning grooves 13 cover the protruding knot part on the cable, thereby positioning the cable. When the positioning sleeve 1 slides, since the protruding knot is in the positioning groove 13, the positioning groove 13 can push the protruding knot, thereby driving the cable to slide.

[0047] Referring to Figure 4 In at least one embodiment, the length of the locking partition 21 is greater than one half and less than four fifths of the length of the positioning block 12. This is to avoid that the locking partition 21 is too long to jam the cable, or that the locking partition 21 is too short to be clamped with the sampling tongs.

[0048] Referring to Figure 5 In at least one embodiment, in order to achieve the effect that the mating sleeve 2 can rotate relative to the positioning sleeve 1 after the positioning sleeve 1 and the mating sleeve 2 are assembled, a mating ring groove 11 is formed in the end face of the positioning sleeve 1 facing the mating sleeve 2. At the same time, a T-shaped ring block 22 is arranged on the end face of the mating sleeve 2 facing the positioning sleeve 1. The T-shaped ring block 22 corresponds to the mating ring groove 11. That is, the mating ring groove 11 is also T-shaped, and the T-shaped ring block 22 can be inserted into the mating ring groove 11, and when the mating sleeve 2 rotates, the T-shaped ring block 22 rotates circumferentially in the mating ring groove 11.

[0049] In addition, the disclosure also provides a sampling forceps comprising two cable locking structures described above, and the sampling forceps further comprises a handle 3, and the handle 3 is axially provided with a sliding hole 31. The two cable locking structures are respectively wrapped from two sides, and the positioning blocks 12 of the two cable locking structures are inserted into the sliding hole 31. At the same time, the two sides of the positioning sleeve 1 are respectively provided with a first mounting column 14 and a first mounting groove 15. The two sides of the mating sleeve 2 are respectively provided with a second mounting column 23 and a second mounting groove 24. When assembled, the positioning sleeves 1 and the mating sleeves 2 of the two cable locking structures are assembled, then the first mounting columns 14 and the first mounting grooves 15 of the two positioning sleeves 1 are aligned, the second mounting columns 23 and the second mounting grooves 24 of the two mating sleeves 2 are aligned, and the positioning blocks 12 of the two positioning sleeves 1 are aligned with the sliding hole 31, then the two cable locking structures are closed, and the installation is completed.

[0050] Referring to Figure 3 In at least one embodiment, the two sides of the sliding hole 31 are respectively provided with a plurality of locking grooves 32, and the locking grooves 32 correspond to the locking partitions 21. In use, after the positioning sleeve 1 clamps the sample by the cable control forceps, the mating sleeve 2 is rotated to make the locking partitions 21 clamped into the locking grooves 32, so as to position the cable, so that the forceps remain in the clamping state without loosening the sample.

[0051] In the several embodiments provided by the present disclosure, it should be understood that the disclosed system, apparatus, and method can be implemented in other ways. The apparatus embodiments described above are only schematic. For example, the division of the units is only a logical function division, and there can be another division manner in actual implementation, and a plurality of units or components can be combined or integrated into another system, or some features can be ignored or not executed. In the above description, the ideal implementation of the present disclosure is described with reference to the ideal embodiment. Based on the above description, those skilled in the related art can make various changes and modifications without departing from the spirit of the present disclosure. The technical scope of the present disclosure is not limited to the content of the specification, and should be determined according to the scope of the claims.
