  In addition, when extracting two liquids by the same amount without mixing the liquids of the syringes 10 and 10 with the double syringe 1a according to the present invention, or when disassembling for member replacement, maintenance, etc., first, the locking The member 9 is pulled up in the opposite direction, the nozzle 7, the mixing element 8 and the locking member 9 are removed from the syringe cover 11, the locking member 9 is further removed from the nozzle 7 and the mixing element 8, and finally the mixing with the nozzle 7. The element 8 may be removed.

  As described above, when the nozzle 7, the mixing element 8, and the locking member 9 are removed and only the syringes 10, 10 and the syringe cover 11 are used, the spout 10g of the syringes 10, 10 inserted through the syringe cover 11, Since 10 g is also separated, each liquid does not come into contact with each other even after being pushed out by the plunger, and two different liquids can be extracted in the same amount.

  The double syringe according to the present invention can firmly and firmly connect the members, does not leak from other than the dispensing path when the two liquids are dispensed, and the components can be easily assembled and disassembled to replace parts. Can be used as an extractor that does not mix the two liquids and does not contact the two liquids, and requires a precise amount of the two liquids to be dispensed. A significant contribution to the industry.
