Syringe Clamp

3 bolts and nuts (M4) are needed. The bolt conecting the two links can be turned tight to fix the piston position in the syringe chamber. Basically it is a priston rod construction where one degree of freedom can be taken away by tightening the joint. The wingnuts can be attached to those bolts to have a better grip. The bolt on the syringe side also serves as a rotational joint. At the same time it clamps the syringe chamber (18 mm diameter) with a circular clamp.
