Administration adjustment device for temporarily maintaining distortion of torsion spring applying rotational force

The drug administration adjusting device according to the present invention comprises: an injection amount setting module (100) for storing torque in a torsion spring (140) disposed in a housing (10) so as to set the amount of a drug to be injected; a drug discharge module (200) that moves by releasing a torque applied to the torsion spring (140) to discharge a set amount of drug to the outside from the cartridge housed in the cartridge holder (30), and includes a torsion spring (140), both ends of which are coupled to the housing (10) and the ratchet tube (120); and an anchor (170) slidably coupled to the inside of the housing (10) in a state of being rotatably coupled to the ratchet tube (120), the anchor (170) comprising: an anchor circumferential protrusion (171) formed on the inner surface so as to protrude in the circumferential direction, and a housing coupling protrusion (172) formed on the outer surface so as to protrude in the axial direction, the anchor circumferential protrusion (171) being formed
