By adopting further arrangement, the protective sleeve can effectively prevent the needle heads of the first, second and third puncture needles from being exposed to hurt operators; meanwhile, the protective sleeve is composed of the upper sleeve and the lower sleeve, so that when the reagent bottle puncture needle is punctured, the upper sleeve is pressed down firstly to coincide with the lower sleeve, the axial length of the protective sleeve is shortened, the head of the reagent bottle is favorably aligned with the puncture needle to be placed in, and then the upper sleeve is pulled upwards.

The utility model discloses still can further set up as the upper end of going up the cover is threaded connection still and is supported the pressure cover that leans on the lower cover, and the lower extreme of going up the cover still is provided with the packing ring that supplies the reagent bottle head to pass.

Adopt further setting, press the cover through setting up, not only effectively enlarged the area of contact of upper end of the cover and staff, be convenient for the upper cover and reagent bottle push down together, press the cover through the spiro union rotating moreover, can also realize the regulation control to the upper cover stroke of pushing down. Through setting up the packing ring, can avoid leading to reagent bottle and chassis directly to take place the striking because of pressing force is too big to play the buffer protection to the reagent bottle at the in-process of pressing.
