Described connection cover is to be connected through a screw thread with outer cylinder body.
Due to using above-mentioned technical proposal, the utility model has the advantages that：
1st, the utility model is when changing liquid transfer gun head, it is only necessary to which a hand depresses connection cover toward the direction of liquid transfer gun head,
Annular slab is set to promote liquid transfer gun head to depart from head of pipette, it is possible to liquid transfer gun head to be changed, it is not necessary to the hands operate, with existing need
The mode for wanting bimanualness to change liquid transfer gun head is compared, and the utility model changes liquid transfer gun head speed faster and can only use singlehanded
Operation, is operated more convenient.In addition, the process for removing liquid transfer gun head using the utility model is more steady, and need not
Liquid transfer gun head is contacted with hand, the generation of pollution can be effectively prevented.
2nd, connection cover of the present utility model is connected by removably with outer cylinder body upper end open, by connection cover and outer barrel
After body separation, it can repair or change spring etc. and more damage part, the service life of extension fixture.
Below, the technology in conjunction with the accompanying drawings and embodiments to the easy vavuum pump liquid-transfering device for changing pipette tips of the utility model is special
Levy and be further described.
