[0031] By adopting the above technical solution, when in use, the produced anhydrous hydrogen fluoride will enter the air guide inner tube 63 when being transported from the first transport pipeline 1 to the connecting frame 3, and then the transported anhydrous hydrogen fluoride will be guided by the air guide inner tube 63 to the driven groove 66 on the driven rotating plate 65, so as to drive the driven rotating plate 65 to rotate, and then drive the fixed ring 64 to rotate, and further drive the speed measuring rotating rod 61 to rotate, so as to drive the two return springs 68 to rotate through the mounting ring 67, and then drive the two mounting discs 69 to rotate, and further drive the two knocking balls 611 to rotate through the side cross bar 610. When the knocking balls 6 When the knocking ball 611 collides with the bell body 612, it will vibrate, and the rotation of the knocking ball 611 will be limited under the limitation of the corresponding bell body 612, so that the corresponding reset spring 68 can be deformed, and when the knocking ball 611 is separated from the bell body 612, the reset spring 68 will drive the corresponding knocking ball 611 to reset, and then the above steps will be repeated, so that the two knocking balls 611 can intermittently hit the two bell bodies 612, and then the two bell bodies 612 can intermittently emit an impact prompt sound, which is further convenient for the user to timely understand the delivery speed of the produced anhydrous hydrogen fluoride according to the interval of the impact prompt sound.

[0032] Working principle: When in use, the produced anhydrous hydrogen fluoride will be introduced into the first delivery pipe 1 for delivery, and then the produced anhydrous hydrogen fluoride will be delivered through the connecting frame 3 and the second delivery pipe 2 in sequence. During this period, the user can start the sampling motor 41, thereby driving the driving gear 43 to rotate, and then driving the driven gear ring 44 to rotate, and further driving the rotating sleeve 42 to rotate, thereby driving the four sampling main pipes 45 and the corresponding sampling bottle body 410 to rotate, and when the rotating sleeve 42 rotates forty-five degrees, the sampling motor 41 is paused, and at this time one of the connecting through holes 46 will be connected to the connecting through hole 11, and then Part of the delivered anhydrous hydrogen fluoride will be introduced into the corresponding sampling main pipe 45 through the connecting through hole 11 and the corresponding connecting through hole 46, and then the anhydrous hydrogen fluoride introduced into the sampling main pipe 45 will be respectively introduced into the corresponding two L-shaped sampling sub-pipes 47, and then the sampled anhydrous hydrogen fluoride will be introduced into the corresponding two sampling bottles 410 through the corresponding connecting sleeve 48 and the one-way sampling valve body 411, and when a proper amount of sample is introduced into the sampling bottle 410, the sampling motor 41 is started again and drives the rotating sleeve 42 to rotate forty-five degrees again, at which time the connecting through hole 11 will be blocked, and during the subsequent use, the user can perform the staged sampling operation according to the above steps;

[0033] When the sample needs to be tested, the user needs to close the first valve 413 corresponding to the sample to be tested, and then the user needs to rotate the two corresponding L-shaped limit rotating tubes 51 in sequence, so as to drive the two corresponding arc-shaped limit clamping blocks 54 to rotate and twist the corresponding limit torsion springs 53, and stop rotating when the L-shaped limit rotating tube 51 rotates ninety degrees. At this time, the arc-shaped limit clamping block 54 will move to the gap between the two corresponding arc-shaped limit clamping plates 52, and the limiting force of the arc-shaped limit clamping block 54 on the corresponding arc-shaped limit clamping plate 52 disappears. Then the user can remove the corresponding sampling bottle 410 and transfer it to a suitable position for sample analysis, and when the sampling bottle 410 needs to be reset and fixed in the later stage, the L-shaped limit rotating tube 51 needs to be rotated ninety degrees again, and then it needs to be The end of the one-way sampling valve body 411 corresponding to the sampling bottle 410 is inserted into the connecting sleeve 48 again, and the limiting guide rod 55 is inserted into the limiting guide hole 56. At this time, the arc-shaped limiting clamping block 54 will pass through the gap between the two corresponding arc-shaped limiting clamping plates 52, and when the arc-shaped limiting clamping plate 52 is again fitted with the connecting sleeve 48, the corresponding L-shaped limiting rotating tube 51 is released, and then the corresponding limiting torsion spring 53 will drive the corresponding L-shaped limiting rotating tube 51 to reverse and reset, thereby driving the corresponding arc-shaped limiting clamping block 54 to reverse and reset, and then the corresponding arc-shaped limiting clamping plate 52 can be conveniently limited and fixed, and further the corresponding sampling bottle 410 can be conveniently limited and fixed, and after the corresponding two sampling bottles 410 are fixed, the first valve 413 can be opened again;

[0034] At the same time, the produced anhydrous hydrogen fluoride will enter the air guide inner tube 63 when being transported from the first transport pipeline 1 to the connecting frame 3, and then the transported anhydrous hydrogen fluoride will be guided by the air guide inner tube 63 to the driven groove 66 on the driven rotating plate 65, so as to promote the driven rotating plate 65 to rotate, and then drive the fixed ring 64 to rotate, and further drive the speed measuring rotating rod 61 to rotate, so as to drive the two return springs 68 to rotate through the mounting ring 67, and then drive the two mounting discs 69 to rotate, and further drive the two knocking balls 611 to rotate through the side cross bar 610. When the knocking balls 611 and the bell are touched, When the body 612 collides and contacts, it will vibrate, and the rotation of the knocking ball 611 will be limited under the restriction of the corresponding bell body 612, so that the corresponding reset spring 68 can be deformed, and when the knocking ball 611 is separated from the bell body 612, the reset spring 68 will drive the corresponding knocking ball 611 to reset, and then the above steps will be repeated, so that the two knocking balls 611 can intermittently hit the two bell bodies 612, and then the two bell bodies 612 can intermittently emit an impact prompt sound, which further facilitates the user to timely understand the delivery speed of the produced anhydrous hydrogen fluoride according to the interval of the impact prompt sound.
