Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1-4 As shown in , the resistance rope puller of this embodiment includes a frame, on which three guide wheels are provided in a triangular shape, and the three guide wheels rotate in conjunction with each other. The pull rope 1 is wound around the three guide wheels, and one of the guide wheels is mounted on the frame through a drive shaft 2. A large gear 3 is also provided on the drive shaft 2, and the large gear 3 is engaged with a small gear 4 for transmission. The small gear 4 is mounted on the frame through a rotating shaft 5, and a magnetic resistance mechanism is also installed on the rotating shaft 5.

[0026] refer to Figure 2In another embodiment, the three guide wheels include a driving wheel 6 and two driven wheels 7. The driven wheels 7 are mounted on the frame via a support shaft 8. The driving wheel 6 is mounted on the drive shaft 2. The outer edges of the driving wheel 6 and the driven wheel 7 are each provided with gear teeth. The two driven wheels 7 and the driven wheel 7 and the driving wheel 6 are respectively driven by gear teeth meshing. The gear teeth meshing between the two driven wheels 7 and between the driven wheel 7 and the driving wheel 6 ensure stability and synchronization during use of the rope puller, making the rope pulling exercise more smooth and fluent.

[0027] refer to Figure 2 In another embodiment, the driving wheel 6 is arranged below the frame, and two driven wheels 7 are symmetrically arranged on both sides above the driving wheel 6, and the pull rope 1 is wound around the driven wheel 7, the driving wheel 6, and the driven wheel 7 in sequence.

[0028] refer to Figure 4 In another embodiment, the magnetic resistance mechanism includes a large magnetic resistance wheel 9 arranged on the rotating shaft 5, and the frame is also provided with an A-axis 10. A magnetic resistance plate 11 is rotatably provided on the A-axis 10. A plurality of strong magnets 12 are provided on the side of the magnetic resistance plate 11 close to the large magnetic resistance wheel 9. The other end of the magnetic resistance plate 11 is connected to a tie wire 13, and the tie wire 13 is installed on the frame through a support 14. The other end of the tie wire 13 is connected to a fine-tuning controller 15 arranged on the frame, and a reset spring 16 is provided between the support 14 and the magnetic resistance plate 11.

[0029] refer to Figure 2-3 In another embodiment, the frame includes a base 17, a front plate 18 and a rear plate 19 are installed on one side of the base 17, and the rotating shaft 5 and the A-axis 10 are respectively installed between the front plate 18 and the rear plate 19; the rear end of the drive shaft 2 is installed on the rear plate 19, and its front end passes through the front plate 18 and is connected to the driving wheel 6; the support shaft 8 and the support 14 are respectively installed on the front and rear sides of the front plate 18.

[0030] refer to Figure 1-2 In another embodiment, a guard plate 20 is provided in front of the front plate 18. The upper side of the guard plate 20 is connected to the front plate 18 via two limiting sleeves 21 respectively provided above the two driven wheels 7. The limiting sleeves 21 can effectively prevent the pull rope 1 from falling out, and can also prevent the pull rope 1 from slipping or falling off during exercise, effectively preventing the trainee from suffering muscle strain caused by the pull rope 1 slipping or falling off.

[0031] refer to Figure 1-2 In another embodiment, two U-shaped fixing frames 22 are installed on the other side of the base 17, and the two U-shaped fixing frames 22 are connected to the base 17 by bolts respectively.

[0032] refer to Figure 2-3In another embodiment, a circle of side guard plates 23 is provided between the front plate 18 and the rear plate 19 ; the fine-tuning controller 15 is installed at the bottom of the side guard plates 23 .

[0033] refer to Figure 1-2 In another embodiment, the drawstring 1 is a closed drawstring.

[0034] When the trainee needs to exercise, he adjusts the gear of the fine-tuning controller 15 as needed: the multiple powerful magnets 12 on the magnetic resistance plate 11 adjust the distance with the magnetic resistance large wheel 9 through the fine-tuning controller 15, and the magnetic field strength near the magnetic resistance large wheel 9 is changed by adjusting the distance, thereby changing the resistance size; when the fine-tuning controller 15 is adjusted to a higher gear, the tie wire 13 is loosened, and the return spring 16 pushes the magnetic resistance plate 11 close to the magnetic resistance large wheel 9, thereby increasing the magnetic field strength and increasing the resistance accordingly. The magnetic resistance large wheel 9 drives the small gear 4 to rotate, and the small gear 4 is meshed with the large gear 3 for transmission, and the small gear 4 is meshed with the large gear 3 for transmission. The resistance is transmitted to the large gear 3 and the transmission from the small gear 4 to the large gear 3, which can significantly amplify the change in resistance intensity again. The large gear 3 drives the active wheel 6. Therefore, the trainee needs a greater pulling force to pull the pull rope 1 so that the pull rope 1 can pass through the driven wheel 7, the active wheel 6, and the driven wheel 7 in sequence for exercise; on the contrary, when the fine-tuning controller 15 is lowered, the tie wire 13 is tightened, the return spring 16 contracts, the magnetic resistance plate 11 moves away from the magnetic resistance large wheel 9, the magnetic field strength is reduced, and the resistance will be weakened accordingly. The trainee only needs a smaller pulling force to pull the pull rope 1. The distance between the magnetic resistance plate 11 and the large magnetic resistance wheel 9 is adjusted by the fine-tuning controller 15. The magnetic field strength near the large magnetic resistance wheel 9 is changed by adjusting the distance, thereby changing the resistance size. It can have multiple different resistance gears and a smoother resistance mechanism, which can adapt to a variety of training environments, diverse training needs and different training groups. In addition, the transmission structure in which the small gear 4 is engaged with the large gear 3 can significantly amplify the effect of changing the resistance intensity to meet the training needs of different intensities. The double amplification or reduction of resistance enables the resistance rope puller to achieve the advantages of small size and small footprint, and achieve the effect of resistance amplification in a smaller volume space. In addition, it can be fixed to a wall or the ground with bolts, and can also be installed on other multi-functional training racks through the U-shaped fixing bracket 22 for use in conjunction with exercise. At the same time, depending on the installation direction, it can meet the requirements of pulling in multiple directions such as downward, upward, and horizontal pulling.
