Therefore, the handrail frame 30 is fastened at the using position by the fastening mechanism 40, and the user can exercise using the treadmill 10.

After the exercise is completed, the user can fold the treadmill 10 by folding the handrail frame 30 and the two support posts 25. To fold the armrest frame, the user pulls the handle of the release handle 60 upward, so that the release handle 60 drives the fastening member 50 to rotate counterclockwise and leave the fastening position, and the fastening portion 54 of the fastening member leaves and no longer fastens the fastening portion 84 of the fastening piece 80, based on the direction of fig. 10 and the fastening mechanism 40 of fig. 10. Thus, the buckling state of the buckle 50 and the buckle piece 80 of the buckling mechanism 40 is released, the armrest frame 30 is not buckled any more and is in a rotatable state, and the user can rotate the armrest frame 30 clockwise as shown in fig. 11, and fold the armrest frame 30 to the folding position shown in fig. 12 and 13, so that the concave surface 34 of the armrest frame 30 faces the rear end of the treadmill 10, and then step on the release member 26 at the front end of the running platform 20, so as to release the buckling state of the two support columns 25 and the running platform 20, and fold the support columns 25 and the armrest frame 30 towards the running platform 20, as shown in fig. 14, the running platform 20 is flatly attached to the concave surface 34 of the armrest frame 30 and the instrument panel 35; finally, as shown in fig. 15, the treadmill 10 is lifted up to be stored in the upright state.

Thus, as shown in fig. 14 and 15, the design of the concave surface 34 of the connecting rod 33 of the handrail frame 30 enables the handrail frame 30 to be completely flush with the running platform 20, and the frame 22 of the running platform 20 is accommodated between the two handrails 31, so that the running platform 20 and the handrail frame 30 are perfectly overlapped, and the most compact folding volume is achieved.

Referring to fig. 13, when the armrest frame 30 is folded, although the elastic member 70 drives the fastening member 50 to rotate clockwise, the connecting block 58 of the fastening member 50 abuts against the bottom edge 411 of the base 41, so that the fastening member 50 and the release handle 60 are positioned and still positioned in the locked position.

To use the treadmill 10, the treadmill 20 is first unfolded, as shown in fig. 12; then, the armrest frame 30 is rotated counterclockwise from the folded position to the use position. As shown in fig. 11, in the process of rotating the armrest frame 30, the body 83 of the buckle piece 80 pushes the buckle 50, so that the elastic element 70 stores elastic energy, and when the armrest frame 30 reaches the use position shown in fig. 9, the buckle 50 is driven by the elastic element 70, and the buckle portion 54 thereof automatically buckles the buckle portion 84 of the buckle piece 80, thereby completing the positioning of the armrest frame 30. It can be seen that when the armrest frame 30 is unfolded, the user does not need to pull the release handle 60, but only needs to rotate the armrest frame 30, and the engaging mechanism 40 will automatically engage the armrest frame 30, so as to achieve the effects of simple operation, easy positioning of the armrest frame, and easy engagement.

Through the technical scheme of the utility model, fold up easily the handrail frame and expand, when folding up the handrail frame, can reduce the volume of treadmill, and handrail 31 folds up into upright form, leans on the pillar to do not stretch protruding, avoid the danger that the user collided the handrail.
