Furthermore, the mobile bar side is uniformly provided with multiple location holes corresponding with the adjusting bolt.

Furthermore, the adjusting cavity bottom is equipped with bearing, and the lead screw bottom is connect with the bearing.

Furthermore, the limit plate and the piston plate two sides are equipped with the rubber with the sampling cavity interior contact Pad.

Furthermore, the sampler barrel is made of transparent plastics material, and the sampler barrel side is equipped with graduation mark.

Furthermore, the handle bottom is connect with the base top.

The utility model the utility model has the advantages that using when by the utility model be placed in experiment desktop on, sampling when operator Member can hold handle on the other hand, to keep the utility model relatively more firm, baffle can play protective action to operator's arm, The scale value that sampling is first determined when sampling, rotates first handle, makes nut seat vertical shift on lead screw, at this time L shape strut Drive limit plate vertical shift, make limit plate be located at than expectation sampling scale more than a piston plate thickness position, then draw Dynamic second handle, to be sampled by sampling head, final piston plate is limited plate limitation and no longer moves, and sampling is completed, this is practical The novel phenomenon that sampling pilot scale drop can be effectively prevented and drain on operator's arm, and sample can be quantitatively extracted roughly Product significantly facilitate the sampling process of operator.

Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

As shown in Figure 1-Figure 3, the utility model provides a kind of technical solution: a kind of pharmaceutical test sampler, including pedestal 1, it is equipped with support column 2 and baffle 3 at the top of the pedestal 1,3 side of baffle is equipped with handle 4,2 top opening of support column, And the 2 top nested encryptions of support column have mobile bar 5,2 side of support column, which is equipped with, adjusts bolt 6, the mobile bar 5 one Side is connected with cross bar 7, and sampler barrel 8 is fixedly installed on the cross bar 7, is equipped with sampling cavity 9 and adjusting cavity in the sampler barrel 8 10, it is vertically provided with lead screw 11 in the adjusting cavity 10, through the adjusting cavity 10 and is connected with first at the top of the lead screw 11 Handle 12,11 outside screw of lead screw are connected with nut seat 13, and 13 side of nut seat is connected with L shape strut 14, the L 14 bottom of shape strut is through the adjusting cavity 10 and is connected with limit plate 15, is equipped with piston plate 16, the work in the sampling cavity 9 It is connected with piston rod 17 at the top of seben 16, the piston plate 16, the sampling cavity 9, institute are sequentially passed through at the top of the piston rod 17 It states adjusting cavity 10 and is connected with second handle 18,9 bottom of sampling cavity is communicated with sampling head 19.
