With the structure of the above specific embodiment, the following benefits can be obtained:

(1) This creation can be achieved through the quick and simple adjustment of the relative rotation angle of the fixed disc 61 and the positioning member 63 of the stroke trajectory adjustment unit 60, and cooperate with the swing of the linkage unit 50 to achieve the adjustment of different body swing movements The movement track provides better movement effect and more exercise fun.

(2) The pulley 32 and the magnetron 31 of the resistance unit 30 are parallel to each other. Design, when the parallelogram linkage structure composed of the front swing lever 51, the rear swing lever 52, the upper link lever 53 and the lower link lever 54 needs to be deformed more, the lower fixing frame 19 can be lengthened forward, Then, the pulley 32 and the magnetron 31 are moved forward, and after passing through the stroke trajectory adjustment unit 60, the parallelogram linkage structure can be deformed at a greater angle, so that the variation of the stroke trajectory of the motion step valve is better and diversified.

(3) The stroke trajectory adjustment unit 60 of this creation is designed to be installed at the end of the front swing rod 51. When the buyer needs an elliptical fitness machine with a relatively low cost and a single motion step valve stroke trajectory without the trajectory adjustment unit 60, it is produced The manufacturer can ship the existing machine without assembling the trajectory adjustment unit 60, and no need to produce machines of other structures; that is, the structure design of this creation can be decided to install the trajectory adjustment unit 60 at any time according to the needs of the buyer. Otherwise, it can flexibly ship, reduce the accumulation of different component inventory, and reduce the pressure of inventory costs and backlog funds.

In summary, this creative department can effectively solve the deficiencies of conventional creation, and can be easily implemented by those with ordinary knowledge in the technical field. However, the above is only one of the preferred embodiments of this creation. However, it should not be used to limit the scope of the implementation of this creation; that is, all equal changes and modifications made in accordance with the scope of the patent application for this creation should still fall within the scope of this creative patent.
