ABSTRACT:
A coupling structure for self-destruction and safety syringe including a coupling member is formed on a front-end of a self-destruction and safety plunger. Upon the plunger being pushed in a hollow barrel until the plunger cannot be pushed any further, a lengthways long slit together with a coupling member are able to deform and thus provide for an allowance spacing when forcedly squeezed, and thereby enables the coupling member to easily and accurately form a complete coupling.
