When the running platform is rotated to the end of the stroke, it indicates Has reached the collapsed position, and the treadmill 2 is in a collapsed state. In addition, the optional unit 80 is installed between the base unit 20 and the running platform 40 to prevent the The 4G running platform can fall down when touched by an external force to avoid accidental effects. As shown in Figs. 6, 8, and 5 and in conjunction with Fig. 3, when the inclination of the running platform 40 is increased, the driving motor 96 of the lifting unit 9G starts to rotate, and the driving rod 95 can be driven to extend and Drive the two guide rods Η to swing. At the same time, the two rollers 63 will slide in the two tank chamber 24 from the first end portion b 2-11 toward the second end portion 212, which will relatively increase the running speed. The distance between the first segment section 4U and the branch floor F achieves the effect of raising the running disturbance. Conversely, as shown in FIGS. 8 and 6 and in conjunction with FIG. 3, when the slope of the running star 40 is to be reduced, the driving horse 彡 μ of the lifting unit 90 is rotated in the reverse direction, and the driving rod 95 can be driven Retract and drive the two guide rods to produce: swing, at the same time, the two rollers 63 will slide in the two tank 24 and from the second to: 212 toward the first end 211, relatively reducing the running The distance between the platform buckle W 411 and the support surface F achieves the effect of reducing the running platform 40. In addition, as shown in FIG. 9, the eccentric rotary unit 7G of the second embodiment of the folding treadmill 2 according to the present invention includes a two-connected eccentric rotary unit 7G having two connecting portions 741 and fixed-portion portions 742 arranged in opposite directions. The rods 74 are respectively fixed to the connecting portion 741 # turntable base 75, and the two eccentric turntables 76 are eccentrically arranged on the two connecting blocks 64 and placed in the two turntable bases 75, and are respectively fixed to The two end portions 212 of the two side rods 21 and two fixing blocks 77 located in the groove chamber 24 are locked between the two fixing portions m and the two fixing blocks 77 by two locking members 78 respectively. , So that the two connecting rods 74 can be fixed.
