The outer wall of the rotating shaft 53 is installed with a driving sprocket 58 for driving the double-row sprocket 59 to rotate. The right end of the input shaft 514 is installed at the left end of the driving sprocket 58. The input shaft 514 can be driven to rotate by turning the handle 2. When the input shaft 514 rotates, it will drive the driving sprocket 58 to rotate synchronously. A fixing plate 513 for fixing the driving sprocket 58 is installed on the inner wall of the shell 1. The right end of the fixing plate 513 is rotatably connected to the left end of the driving sprocket 58. By using the fixing plate 513 to fix the driving sprocket 58, it can be prevented from deflecting during the rotation process. The left end of the mounting beam 8 is close to the front end of the rotating shaft 53. A rotating shaft 54 is penetrated and rotatably connected to drive the pulley 515 to rotate. A one-way bearing 56 is installed on the outer wall of the rotating shaft 54 for driving the rotating shaft 54 to rotate in one direction. When the one-way bearing 56 rotates clockwise, it can drive the rotating shaft 54 to rotate, while when the one-way bearing 56 rotates counterclockwise, it will idle and cannot drive the rotating shaft 54 to rotate. A one-way bearing 57 is installed on the outer wall of the rotating shaft 54 near the left end of the one-way bearing 56 for driving the rotating shaft 54 to rotate.

[0032] Reference Figure 1 - Figure 3The left end of the double-row sprocket 59 is fixedly connected with a driving wheel 512 for driving the passive wheel 511 to rotate. The driving wheel 512 and the passive wheel 511 are meshed with each other. When the driving wheel 512 rotates, it will drive the passive wheel 511 to rotate in the opposite direction. The right end of the second rotating shaft 54 is fixedly connected with a pulley 515 for driving the output shaft of the magnetic induction motor 52 to rotate. A magnetic induction motor 52 for generating resistance is installed near the top of the inner wall of the shell 1. When the output shaft of the magnetic induction motor 52 rotates, it will cut the magnetic flux lines inside it to generate electricity and generate resistance. The magnetic induction motor 52 and the pulley 515 are connected by a belt drive. When the pulley 515 rotates, it will drive the output shaft of the magnetic induction motor 52 to rotate through the belt.

[0033] Working principle: When the operator turns the handle 2 up and down, the input shaft 514 will drive the driving sprocket 58 to rotate. When the driving sprocket 58 rotates clockwise, it will drive the double-row sprocket 59 to rotate clockwise. At this time, the double-row sprocket 59 can drive the rotating shaft 2 54 to rotate clockwise through the one-way bearing 1 56. When the driving sprocket 58 rotates counterclockwise, it will drive the double-row sprocket 59 to rotate counterclockwise. At this time, the double-row sprocket 59 will not be able to drive the rotating shaft 2 54 to rotate through the one-way bearing 1 56, but the double-row sprocket 59 The chain can drive the passive sprocket 510 to rotate counterclockwise, the passive sprocket 510 will drive the active wheel 512 to rotate synchronously, the active wheel 512 will drive the passive wheel 511 to rotate clockwise, and the passive wheel 511 will drive the rotating shaft 2 54 to rotate clockwise through the one-way bearing 2 57. In this way, when the operator moves the handle 2 up and down, the pulley 515 can be driven to rotate in one direction all the time, and the pulley 515 will drive the output shaft of the magnetic induction motor 52 to rotate and cut the magnetic flux lines, so that resistance can be generated to achieve the training effect.
