摘要: A safety syringe cylinder has a structure for attaching a syringe needle precisely. The syringe needle can be retracted into the syringe cylinder for bending. A hook seat is formed at a lower end of the needle. An annular hook groove is formed at a top end of the push rod cap. The hook seat is engaged with the annular hook groove so as to control the displacement and bending process of the syringe needle. Thereby, the processing of undesired syringe needle is safe, reliable and convenient.
