Under this structural design, guarantee that the installation of helmet is firm reliable.

Preferably, the positioning convex column on the end plate of the cap body is barrel-shaped, and a concave hole extending into the positioning convex column is formed on the outer end face of the end plate of the corresponding cap body. Under this structural design, the injection moulding of helmet of being convenient for.

The present invention will be further described with reference to the accompanying drawings.

Detailed Description

Referring to the accompanying drawings 1-4, the utility model discloses a liquid medicine mixes uses two-way, including L type main part 1, L type main part 1 includes intermediate junction seat 11 and two syringe connectors 12, is equipped with the L type of two syringe connectors 12 of intercommunication in the intermediate junction seat 11 and mixes liquid passageway 111, and two syringe connectors 12 all are furnished with helmet 2. The intermediate connection base 11 is a flat cylinder, and the two syringe connectors 12 are integrally formed on the circumferential surface side of the intermediate connection base 11. The middle connecting seat is flat, is convenient for handheld operation and is convenient for the disassembly and connection operation of the syringe and the syringe connector.
