The control component controls the force of the swinging member 1 during the swinging, thereby controlling the swinging force and ensuring the normal exercise effect. The control component includes: an end portion rotatably connected to the rotating shaft 4 A control member 3 is provided at the front end of the control member 3, and a push rod 6 is provided. The control member 3 controls the position of the push rod 6, so as to further control the swing force of the swing member 1 through the push rod 6; a resistance member 5 abuts against the side wall of the push rod 6 and passes through the rotating shaft 4, and one end of the resistance member 5 abuts against the push rod 6 and the other end abuts against the inside of the swing member 1. The position of the push rod 6 controls the force of the resistance member 5 abutting against the swing member 1, so that the resistance of the swing member 1 is adjustable, that is, the output force of the operator exercising can be adjusted, the intensity of the exercise can be adjusted in a targeted manner, and the applicable population of the device is increased.
[0021] Preferably, a rotating sleeve 11 is provided at the top of the swinging member 1 of the utility model, and an arc-shaped plate which fits with the inner wall of the rotating sleeve 11 is provided at the end of the resistance member 5, so as to ensure that when the resistance needs to be increased, the resistance of the rotating sleeve 11 during rotation is increased through the fitting force between the arc-shaped plate and the inner wall of the rotating sleeve 11, thereby realizing that the swing resistance of the swinging member 1 is provided through the resistance of the arc-shaped plate, and a sliding sleeve 7 which is slidingly sleeved on the sliding column 7 of the resistance member 5 is provided between the resistance member 5 and the push rod 6, and a thrust spring 8 is provided between the sliding sleeve 7 and the sliding column 7, and by providing the sliding sleeve 7 structure, it is ensured that the push rod 6 slides against the sliding sleeve 7, thereby compressing or releasing the elastic force of the thrust spring 8, and by changing the elastic force of the thrust spring 8, the pressure of the arc-shaped plate on the inner wall of the rotating sleeve 11 is adjusted, and the swing resistance of the swinging member 1 is further adjusted, thereby realizing the adjustment of the force of the swinging member 1.
[0022] See also Figure 2 , Figure 3 and Figure 5 In addition, a mounting hole 10 is provided on the rotating shaft 4 of the utility model, and the push rod 6 is slidably connected to the inside of the mounting hole 10. The side wall of the mounting hole 10 is provided with a limiting convex edge 9, and the side wall of the push rod 6 is provided with a limiting groove 64 that cooperates with the limiting convex edge 9. The limiting groove 64 cooperates with the limiting convex edge 9 to ensure that the push rod 6 only slides but does not rotate inside the mounting hole 10, thereby ensuring that when the control member 3 rotates, the push rod 6 can rotate relative to the control member 3, thereby achieving the technical effect of rotating the control member 3 to adjust the position of the push rod 6.

The other end is provided with a guide bevel 63 and a force-bearing portion 62 cooperating with the sliding sleeve 7. When the sliding sleeve 7 abuts against the force-bearing portion 62, the resistance of the resistance member 5 to the sliding sleeve 7 is the largest, and the force required for the swinging member 1 to swing is also the largest at this time. The guide bevel 63 acts on the sliding sleeve 7, so that the sliding of the sliding sleeve 7 is in a smooth linear process, thereby ensuring that the adjustment of the resistance is in a linear change, and realizing a stepless change of the resistance.
[0024] Better yet, the control member 3 of the utility model includes a limiting flange 32 for limiting the position of the control member 3, a rotating disk 31 is provided at one end of the control member 3 located outside the rotating shaft 4, and a handle is provided on the rotating disk 31 to ensure that the control member 3 can be rotated more conveniently, a spherical head is provided at the end of the sliding sleeve 7, and a limiting portion is provided on the inner side of the opening of the sliding sleeve 7 to limit the sliding column 7 from sliding out, the spherical head reduces the friction between the push rod 6 and the sliding sleeve 7, and at the same time the limiting portion limits the position of the sliding column 7 to prevent the sliding column 7 from falling off and affecting the control effect.
[0025] In this embodiment, before use, the force that the swinging member 1 needs to overcome when swinging is first adjusted by operating the rotating handle. When the rotating handle is rotated, the threaded sleeve 33 and the push rod 6 rotate relative to each other. At this time, the position of the push rod 6 moves along the axial direction of the mounting hole 10, thereby adjusting the position of the sliding sleeve 7. The movement of the sliding sleeve 7 realizes the adjustment of the clamping force of the thrust spring 8. At this time, the clamping force between the arc plate and the rotating sleeve 11 changes, thereby changing the friction force, thereby realizing the adjustment of the force of the swinging member 1.
