ABSTRACT:
A hand developing device comprises two handles, one elastic element and one adjusting member. The two handles are so pivoted together at one end thereof as to form a pivoting point serving as a fulcrum on which the two handles turn. The elastic element is disposed between the two handles such that the elastic element can be forced out of shape by the pressing portions of the two handles so as to bring about a damping effect. The elastic element is capable of returning mildly to its original form after being forced out of shape by the two handles. The adjusting member is disposed between the two handles such that the adjusting member facilitates an adjustment of the distance between the center of the elastic element and the pivoting point of the two handles, thereby resulting in a change in the damping magnitude of the hand developing device.
