1. A transfer pump for a fixed amount of fluid comprising:
a tube guide block into which a fluid transfer tube is inserted so that the fluid transfer tube is partially exposed;
a tube compression block arranged to be capable of reciprocating movement on the tube guide block and compressing an exposed portion of the tube inserted into the tube guide block to transfer fluid;
an air cylinder which has a rod connected to the tube compression block and reciprocates the tube compression block by reciprocating the rod in a linear direction using compressed air; and an elastic member which is externally connected to the air cylinder and applies elastic force to the air cylinder and causes the tube compression block to compress the tube.
