The injection needle is placed on the syringe by rotating inside the spiral part of the syringe and is locked in its spiral grooves. In these syringes, due to the screwing of the needle head on the syringe, the percentage of leakage or jumping of the needle head from the syringe during injection is very small and zero. On the other hand, it is easily possible to change the needle head on such syringes when the needle head needs to be changed.
