Exercise device with swing function

An exercise device with a swing motion, comprising:

• a main body having a base which includes a front part and a back part;
• and
• a plurality of support mechanisms disposed on the front part and the back part respectively, each of the plurality of support mechanisms having a height and disposed upon a support surface to sustain the base;
• wherein each of the plurality of support mechanisms is changeable in height, and when the main body is controlled to drive the base, the base forces the plurality of support mechanisms to change in height respectively, so that the main body is inclined to any direction in a swing motion;
• wherein the main body includes a support frame having a handle, a seat and a rotating mechanism driven by treading
• wherein the support mechanism includes a fixed cylinder, a first elastic member, a support cylinder and a foundation, the fixed cylinder is fastened with the base, and the fixed cylinder includes a hollow space therein, the foundation is disposed upon the support surface, and the support cylinder is pivoted on the foundation and is extended into the hollow space, the first elastic member is disposed in the hollow space and abuts a top surface of the fixed cylinder at an end thereof and abuts the support cylinder at another end thereof, the motion of the base enables deformation of the first elastic member to change in height and thereby change the support mechanism in height.
