The following detailed description will be further explained with reference to the above drawings the utility model.
Specific embodiment
Referring to Fig. 1, in a kind of better embodiment of the utility model, a kind of excrement sampling rod, including stretch and adopt
Sample bar 1, press component 2 and hair brush structure 3, the flexible thief rod 1 are hollow structure, and one end is sample suction port, and the other end is set
There is end cap.Further, the flexible thief rod 1 includes the first rod piece 11 and the second rod piece 12, under first rod piece 11
End is sample suction port, and the inner sidewall of the upper end is equipped with internal thread segment；The lower end outside of second rod piece 12 be provided with it is described interior
The external thread section that thread segment matches, second rod piece 12 and first rod piece 11 pass through the thread segment activity being mutually matched
Connection reaches first rod piece 11 and second rod piece 12 generation relative movement by rotation and stretches described in elongation or contraction
The effect of contracting thief rod 1, the end cap are set to the upper end of second rod piece 12.
The press component 2 includes piston rod 21, piston 24, press head 22 and return spring 23, and the piston rod 21 is worn
If the end cap, and be flexibly connected with the end cap, the piston 24 is set on the piston rod 21 close to the sample suction port
One end, the edge of the piston 24 combines closely and is flexibly connected with the inner sidewall of the flexible thief rod 1, in order to avoid described
Flexible thief rod 1 is when drawing just sample since gas leakage effect draws effect.The press head 22 is set on the piston rod 21
One end far from the sample suction port, one end of the return spring 23 connect the press head 22, and the other end connects the end cap,
The elastic direction of the return spring 23 is parallel with the activity direction of the piston rod 21, so that the piston rod 21 is unclamping
It is returned under the action of 23 elastic force of return spring after the press head 22 in situ.Further, 23 sets of the return spring
On the piston rod 21, so that the return spring 23 is generated in stress is parallel to 21 activity direction of piston rod
Elastic force.When drawing just sample, piston 24 is pushed by pressing the press head 22 so that sky in the flexible thief rod 1
Gas discharge, then unclamping press head 22 makes to generate negative pressure in sampling rod, thus can successfully draw just sample, improves and inhales sample just sample
Success rate, therefore, completing exhaust-absorption of sampling rod by pressing-release to press head 22-pressing, just sample-release is just
The process of sample.
The hair brush structure 3 is set to the side on the piston 24 close to the sample suction port, and the hair brush structure 3 has
Brush head 32, the brush head 32 stretch out the sample suction port by the telescopic action of the flexible thief rod 1 or are placed in described flexible
In thief rod 1, reaches first rod piece 11 and second rod piece 12 generation relative movement by rotation and stretched described in contraction
The effect of contracting thief rod 1, so that the hair brush structure 3 is caused to stretch out sample suction port, with uniform for applying the just sample booth on slide,
It does not need by external tools, it is simple and convenient.Further, described when the elongation of flexible thief rod 1 to its maximal tensility
Hair brush structure 3 is less than the maximal dilation amount of the flexible thief rod 1 to the distance of the sample suction port, to ensure the hair brush structure
3 by shortening the flexible extended sample suction port of thief rod 1.Further, the hair brush structure 3 includes brush handle 31 and institute
State brush head 32, one end of the brush handle 31 connects the piston 24, and the other end is arranged the brush head 32, at the return spring 23
In nature and when the flexible thief rod 1 is not shunk, the hair brush structure 3 is placed in the flexible thief rod 1, and institute
It states brush head 32 and stretches out second rod piece 12 close to the port of described sample suction port one end, to ensure that the hair brush structure 3 passes through contracting
The short flexible extended sample suction port of thief rod 1.The size of the brush head 32 is less than the size of the sample suction port, to guarantee
The brush head 32 can stretch out the sample suction port.
Working principle:
Air when drawing just sample, when by pressing the press head 22 to push piston 24 in flexible thief rod 1
Discharge, then unclamping press head 22 makes to generate negative pressure in sampling rod, thus complete by pressing-release-pressing to press head 22
At the process of exhaust-absorption just sample-release just sample of sampling rod.After inciting somebody to action on just sample addition slide, make described first by rotation
Rod piece 11 and second rod piece 12 occur relative movement and have the function that shrink the flexible thief rod 1, to cause hairbrush
Structure 3 stretches out sample suction port, with uniform for that will apply after just sample is added on slide to just sample booth.
Above description is the detailed description for the preferable possible embodiments of the utility model, but embodiment is not limited to
The patent claim of the utility model, the same changes or modifications completed under technical spirit suggested by all the utility model
Change, should belong to the covered the scope of the patents of the utility model.
