Referring to FIGS. 1 to 4 at the same time, the control element 61 may include a rotating body 611 , a first fixing pin 612 , a first spring 613 , a pressing member 614 , a pin 615 , and a second spring 616 . The blocking element 63 may include a sheet body 630 , a first sleeve 631 , a second sleeve 632 , a button 633 , an element 634 , a third spring 635 , and a pressing piece 636 .

The first sleeve 631 and the second sleeve 632 are disposed on the sheet 630 . The first sleeve 631 passes through the standpipe set 4 and is fixed with the standpipe set 4 . In another embodiment, the first sleeve 631 and the second sleeve 632 can be regarded as elements of the riser set 4, wherein the first sleeve 631 is fixed to the corresponding perforation of the riser set 4, and the sheet 630 is then connected to the first The sleeve 631 or the riser set 4 is fixed, and the fixing method is, for example but not limited to, welding, screwing, tight fit and the like. One end of the rotating body 611 is against the pressing member 614 , and the first spring 613 is located between the pressing member 614 and the rotating body 611 . The first fixing pin 612 has an end 612 against the pressing member, and a second spring 616 sleeved on the other end. One end of the rotating body 611 , the first spring 613 , the pressing member 614 , and one end of the first fixing pin 612 are located in the first sleeve 631 passing through the standpipe set 4 . The first spring 613 can provide a force in the x direction to push the screw body 611 , and the second spring 616 can provide a force in the x direction to push the first fixing pin 612 . In addition, the rotating body 611 can have a groove 6110 , and the pin 615 is located in the groove 6110 , and the pin 615 can move in the groove 6110 . As shown in FIG. 2 , the peg 615 is located at the first end 6110A of the groove 6110 when the treadmill is in the use position.

See Figure 5. When the user wants to fold the treadmill, the rotating body 611 can be rotated until the pin 615 moves to the second end 6110B of the groove 6110 . At this time, the relationship between the control element 61 , the blocking element 63 and the riser set 4 is shown in the sectional view of FIG. 6 . The rotating body 611 pushes the pressing member 614 to press the first fixing pin 612 , so that a part of the first fixing pin 612 originally located in the standpipe set 4 is pushed out of the standpipe set 4 . In this way, the riser set 4 can rotate around the axis 22 (as shown in FIG. 5 ). At this time, as shown in FIG. 7 , the user can fold the riser set 4 in the direction of the arrow with the shaft 22 as the center. When the standpipe set 4 rotates, the first spring 631 gives a pushing force to the rotating body 611 , so that the rotating body 611 returns to its original position, so that the pin 615 returns to the first end 6110A of the groove 6110 . At the same time, the second spring 616 will give the first fixing tip 612 a pushing force in the direction x, and the plate body 630 of the blocking element 63 can prevent the first fixing tip 612 from being ejected due to the pushing force.
