1. A manually operated press, comprising:
a shaft;
an actuating member coupled to the shaft;
a press ram coupled to the shaft; and
a reset mechanism that is configured to reset the actuating member;
wherein an actuation of the actuating member is converted into a stroke movement of the press ram;
wherein the reset mechanism is configured to counteract the actuation of the actuating member and to cause a return movement of the press ram opposite the stroke movement,
wherein the reset mechanism comprises a spiral spring,
wherein a radially inner end of the spiral spring is attached to the shaft,
wherein the spiral spring comprises a first connecting link at the radially inner end,
wherein the first connecting link comprises a curved portion that is integrally connected to the spiral spring, and
wherein the shaft comprises a web that is oriented parallel to a longitudinal axis of the shaft, wherein a cavity is arranged between the web and an outer side of the shaft facing towards the web, and wherein the first connecting link engages in the cavity.
