[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0054] Reference Figure 1-5 A clinical microbiology detection sampler shown includes:

[0055] Housing assembly 100;

[0056] The force storage device 200 is installed inside the housing assembly 100 and is compressed to store force when subjected to force;

[0057] An adjusting member 300 , which is fixed to one end of the force storage device 200 and slides inside the housing assembly 100 under the push of the force storage device 200 ;

[0058] A plurality of clamping members 400 are provided and fixed to the adjusting member 300 in an annular array. The clamping members 400 release the clamping of the swab when the clamping members 400 extend out of the housing assembly 100.

[0059] The pushing device 500 is fixed to the other end of the force storage device 200 and squeezes the force storage device 200 under the action of external force, so that the force storage device 200 drives the adjusting member 300, the clamping member 400 and the swab to move.

[0060] During wiping, a thrust is applied to the pushing device 500, causing the pushing device 500 to squeeze the force storage device 200, causing the force storage device 200 to compress and store force, and pushing the adjusting member 300 and the clamping member 400 to move, thereby driving the swab to extend out of the housing assembly 100 and into the oral cavity to collect microorganisms, detached cells, or secretions. When the collection is completed, the thrust applied to the pushing device 500 is slowly released, and the force of the force storage device 200 is released, pushing the adjusting member 300 and the clamping member 400 back to their original positions, and driving the swab back into the interior of the housing assembly 100.

[0061] When replacing the swab, a thrust is applied to the pushing device 500, so that the force storage device 200 is compressed and stored, and the adjusting member 300 and the clamping member 400 are pushed to move, so that the clamping member 400 and the swab are moved out of the housing assembly 100. When the clamping member 400 moves out of the housing assembly 100, the adjusting member 300 applies a pulling force to the clamping member 400, so that the clamping member 400 is deformed and the clamping is released. Then the swab can be removed from the adjusting member 300, and then a new swab can be inserted into the adjusting member 300. When the thrust applied to the pushing device 500 is slowly released, the force of the force storage device 200 is released, so that the adjusting member 300 and the clamping member 400 return to their original positions, and the clamping member 400 clamps the swab.

[0062] The clamping member 400 can clamp and fix the swab during use, allowing the swab to penetrate the oral cavity normally to collect microorganisms, shed cells or secretions. During testing, the swab can be completely pushed out and the clamping of the swab can be released, so that the swab can be removed and replaced normally without disassembling the sampler.

[0063] The pulling assembly 330 can pull the clamping member 400 when the receiving plate 310 slides to the opening of the housing assembly 100 , causing the clamping member 400 to deform outward and release the clamping member 400 from fixing the swab.

[0064] In some embodiments of the present invention, in order to make the force storage device 200 drive the clamping member 400 to move, refer to Figure 3 As shown, the adjustment member 300 includes:

[0068] The receiving plate 310 is connected to the force storage device 200 and drives the clamping member 400 to move under the push of the force storage device 200;

[0069] The plug-in sleeve 320 can be used to insert the swab for temporary positioning, so that the swab can be replaced normally, and the clamping member 400 can be driven to move synchronously when the receiving plate 310 slides.

[0070] In some embodiments of the present invention, in order to pull the clamping member 400 to deform outward, refer to Figure 4 As shown, the pulling assembly 330 includes:

[0071] The sliding sleeve 331 is slidably mounted on the outer side of the receiving plate 310;

[0072] A plurality of pull ropes 332 are provided, and both ends of the pull ropes 332 are fixedly connected to the sliding sleeve 331 and the clamping member 400, and pull the clamping member 400 to move when the sliding sleeve 331 slides;

[0074] When the receiving plate 310 slides under the push of the force storage device 200, it drives the sliding sleeve 331 to move toward the limiting ring 333. When the clamping member 400 opens and extends out of the housing assembly 100, the sliding sleeve 331 and the limiting ring 333 come into contact and squeeze each other, causing the sliding sleeve 331 to slide relative to the receiving plate 310 and pull the clamping member 400 through the pull rope 332 to phase-change and store force.

[0075] The sliding sleeve 331 slides relative to the receiving plate 310 when the sliding sleeve 331 and the limiting ring 333 are squeezed against each other.

[0076] The pull rope 332 is arranged to pull the clamping member 400 to deform when the sliding sleeve 331 slides, and to pull the sliding sleeve 331 to return to its original position when the clamping member 400 recovers.

[0085] The receiving rod 240 is fixed to the left side of the sliding plate 230 and is fixedly connected to the receiving plate 310 through the compression spring 220 and the positioning ring 210. When the sliding plate 230 slides, the receiving rod 240 is driven to slide synchronously.

[0086] When the sliding plate 230 is pushed by the pushing force of the pushing device 500, the compression spring 220 is squeezed, so that the compression spring 220 is compressed and stored, and at the same time, the receiving rod 240 is driven to move synchronously; after the pushing force on the sliding plate 230 disappears, the pressure of the compression spring 220 is released, so that the compression spring 220 pushes the receiving rod 240 and the sliding plate 230 back to their original positions;
