When the pedal assembly 4 drives the crank assembly 5 to rotate, the connecting part can perform circular motion with the rotating shaft 51 as a center and the connecting piece 52 as a radius.

Optionally, the fastener 57 is a screw.

Alternatively, referring to fig. 17, the pedal assembly 4 includes a link 41, a cartridge 42, and a foot pedal 43. The length of the link 41 extends along the length of the exercise machine. The front end of the connecting rod 41 is hinged with the swing rod 21 of the swing arm assembly 2, and the clamping seat 42 and the foot pedal 43 are arranged at the rear end of the connecting rod 41. Foot pedal 43 is provided for the user to pedal, and foot pedal 43 is located on top of link 41. The clamping seat 42 is positioned below the pedal 43, and the sliding groove 44 and the clamping groove 45 are arranged on the clamping seat 42. The number of the clamping grooves 45 is two, the two clamping grooves 45 are respectively arranged on two sides of the width direction of the chute 44, the notch of the clamping groove 45 is communicated with the chute 44, and the notch of the two clamping grooves 45 are opposite. Both ends of the limiting plate 58 can be respectively inserted into the two clamping grooves 45.

In the first training state, the connecting shaft 53 of the crank assembly 5 is inserted into the chute 44, and the roller 54 is located between the two clamping plates 421. The circumference of the roller 54 is provided with a groove matching with the outer contour of the connecting rod 41, the roller 54 is abutted with the connecting rod 41 through the groove, and when the connecting part of the crank assembly 5 moves along the length direction of the chute 44, the roller 54 rolls along the length direction of the connecting rod 41, so that the roller 54 is in rolling connection with the connecting rod 41. The limiting plate 58 is inserted into the corresponding sliding groove 44 on the clamping plate 421. In the first training state, the limiting plate 58 does not need to have a connection relationship with the clamping seat 42, and therefore, the size of the limiting plate 58 is smaller than the size of the sliding groove 44, so that the limiting plate 58 is spaced from the groove wall of the sliding groove 44, and friction force between the crank assembly 5 and the clamping seat 42 is reduced. When the user steps on the pedal 43, under the rolling connection action of the connecting rod 41 and the roller 54, the clamping seat 42 drives the crank assembly 5 to rotate, the connecting part of the crank assembly 5 moves circularly, and meanwhile, the connecting part moves along the length direction of the sliding groove 44, and the pedal assembly 4 swings up and down around the hinging point of the pedal assembly and the swing arm assembly 2, so that the stepping up and down movement of the user is met.

In the second training state, the connecting shaft 53 of the crank assembly 5 is inserted into the slot 45, and the limiting plate 58 is inserted into the corresponding slot 45 on the clamping plate 421, so that the connecting portion of the crank assembly 5 cannot move along the length direction of the chute 44 under the limiting effect of the slot 45. At this time, the connecting portion of the crank assembly 5 can rotate relative to the holder 42. When the user steps on the pedal 43, under the rotation connection action of the clamping seat 42 and the connecting part, the clamping seat 42 drives the crank assembly 5 to rotate, and the connecting part of the crank assembly 5 performs circular motion. The front end of the connecting rod 41 swings back and forth along with the swing arm assembly 2, and meanwhile, the rear end of the connecting rod 41 moves circularly along with the crank assembly 5, so that the whole pedal assembly 4 moves in an elliptical shape to meet the elliptical stepping motion of a user.

When the exercise machine is required to be switched from the first training state to the second training state, the limiting plate 58 is pulled out towards the direction deviating from the roller 54 through the handle 59, then the limiting plate 58 is rotated to enable the limiting plate 58 to be opposite to the clamping groove 45, and then the limiting plate 58 is inserted into the clamping groove 45. When the exercise machine is required to be switched from the second exercise state to the first exercise state, the limiting plate 58 is pulled out by the handle 59 in a direction away from the roller 54, the limiting plate 58 is rotated to face the sliding groove 44, and then the limiting plate 58 is inserted into the sliding groove 44.

In this embodiment, referring to fig. 1, the front-rear direction of the exercise machine is the X direction shown in the drawing, and the left-right direction of the exercise machine is the Y direction shown in the drawing. During training, a user stands on the pedal assembly 4, and holds the swing arm assembly 2 by two hands. The front, back, left and right directions of the user are matched with the front, back, left and right directions of the exercise equipment.
