A sliding groove 204 is provided at the right end of the handle 1, and the outer end of the operating rod 202 is fixedly connected to a limiting rod 205.

[0030] By setting up the disengagement component 2, after the sampling is completed, the two operating rods 202 are pushed from the right end of the handle 1 to the middle, which can drive the operating rod 202 to slide toward the middle along the connecting rod 201, thereby driving the spring 203 to be compressed, so that the limiting rod 205 is separated from the limiting groove 303, and then the handle 1 can be directly separated from the sampling rod 301 without the need for breaking and other operations. The separation is very simple and fast, and the liquid inside the sample bottle will not splash due to uneven force, making the sampling safer.

[0031] Reference Figure 1-Figure 3 A pair of operating rods 202 both penetrate the slide groove 204 and extend to the outside of the slide groove 204. The operating rod 202 is slidably connected to the slide groove 204. The front end of the spring 203 is fixedly connected to the front operating rod 202, and the rear end of the spring 203 is fixedly connected to the rear operating rod 202.

[0032] By setting the spring 203, when installing the sampling rod 301, first push the two operating rods 202 toward the middle to compress the spring 203, and after aligning the limit groove 303 of the sampling rod 301 with the limit column, release the operating rod 202, and the operating rod 202 and the limit rod 205 are reset to the outside under the action of the spring 203, so that the limit rod 205 is inserted into the limit groove 303, which is also very simple during installation.

The operating rod 202 and the limiting rod 205 extend into the interior of the sampling rod 301. The left end of the sampling rod 301 is fixedly connected with a sampling swab head 302. The sampling rod 301 extends into the interior of the handle 1, and the sampling rod 301 is movably connected to the handle 1.

[0034] By setting the sampling component 3, the sampling rod 301 cooperates with the sampling swab head 302 to be inserted into the oral cavity or nasal cavity of the patient and scrapes the respiratory tract to sample the respiratory virus.

[0035] Reference Figure 1 and Figure 4 The outer end of the sampling rod 301 is provided with a limiting groove 303, and the limiting grooves 303 are distributed in front and back.

[0036] Reference Figure 1 and Figure 4 The limiting rod 205 extends into the limiting groove 303 and is movably connected to the limiting groove 303 , and the limiting rod 205 is adapted to the limiting groove 303 .

The protection cover 403 covers the patient's mouth and nose to prevent saliva from splashing due to sneezes, etc., and the absorbent cotton 404 can absorb saliva.

[0041] Working principle: When installing the sampling rod 301, first push the two operating rods 202 toward the middle to compress the spring 203. After the limiting groove 303 of the sampling rod 301 is aligned with the limiting column, release the operating rod 202. The operating rod 202 and the limiting rod 205 are reset to the outside under the action of the spring 203, so that the limiting rod 205 is inserted into the limiting groove 303.

[0042] Then the sampling rod 301 cooperates with the sampling swab head 302 to be inserted into the oral cavity or nasal cavity of the patient and scrapes the respiratory tract to sample the respiratory virus;

[0043] Then unscrew the connecting sleeve 402 and the threaded sleeve 401, let the protective cover 403 move to the right, and then push the two operating rods 202 from the right end of the handle 1 to the middle, which can drive the operating rod 202 to slide toward the middle along the connecting rod 201, thereby driving the spring 203 to compress, so that the limiting rod 205 disengages from the limiting groove 303, and then the handle 1 can be directly separated from the sampling rod 301, allowing the sampling rod 301 and the sampling swab head 302 to fall into the sampling bottle, and the protective cover 403 can be directly discarded.
