When the distance between the two pulley bodies 58 needs to be adjusted, the rotating wheel 53 is first rotated. The rotation of the rotating wheel 53 drives the threaded rod 52 to rotate. Since the threads on the surface of the threaded rod 52 are reverse threads with the rotating wheel 53 as the center, when the rotating wheel 53 drives the threaded rod 52 to rotate, the two displacement plates 55 threadedly connected on the surface of the sliding rod 54 move in the direction of moving away from or approaching each other on the surface of the sliding rod 54. The two displacement plates 55 move in the direction of moving away from or approaching each other on the surface of the sliding rod 54, driving the two pulley bodies 58 to move in the direction of moving away from or approaching each other.

[0034] Working principle: by setting the auxiliary device 4, when it is needed to use the device, first push the T-plate 46, the movement of the T-plate 46 drives the hinged plate 45 to move, the movement of the hinged plate 45 drives the two slide plates 43 to move in the direction away from each other in the inner box of the slide groove 42, the movement of the slide plate 43 in the direction away from each other in the inner part of the slide groove 42 will drive the spring 44 to stretch, and at the same time, the movement of the T-plate 46 also drives the insertion rod 47 to move, when the insertion rod 47 moves to a suitable position, then the shaft 41 is inserted into the interior of the mounting ring 3, when the shaft 41 and the mounting ring 3 are plugged in, release the T-plate 46, use the resilience of the spring 44 to reset the insertion rod 47, the insertion rod 47 resets and then inserts itself The rod 47 is inserted into the insertion hole 48, and the insertion hole 48 is plugged into each other to limit the rotating shaft 41 inside the mounting ring 3. Then, the entire device is installed through the mounting plate 1. When in use, the pull rope is passed through the inner hole of the rotating shaft 41 and through the hole surrounded by the two pulley bodies 58. When the pull rope is pulled, the pull rope is slidably connected to the pulley body 58 to reduce the friction between the pull rope and the rope outlet position. Through the cooperation of the above-mentioned structure, when the pull rope is pulled at an angle, the pulley frame 2 can rotate 360 ​​degrees in the pulling direction of the pull rope, thereby realizing a large-angle bending movement of the pull rope, and the pull rope is slidably connected to the pulley body 58, which can reduce friction, thereby giving the fitness person a more comfortable fitness experience. When the distance between the two pulley bodies 58 needs to be adjusted, the rotating wheel 53 is first rotated. The rotation of the rotating wheel 53 drives the threaded rod 52 to rotate. Since the threads on the surface of the threaded rod 52 are reverse threads with the rotating wheel 53 as the center, when the rotating wheel 53 drives the threaded rod 52 to rotate, the two displacement plates 55 threadedly connected on the surface of the sliding rod 54 move in the direction of moving away from or approaching each other on the surface of the sliding rod 54. The two displacement plates 55 move in the direction of moving away from or approaching each other on the surface of the sliding rod 54, driving the two pulley bodies 58 to move in the direction of moving away from or approaching each other. The two pulley bodies 58 move in the direction of moving away from or approaching each other, driving the two sliding plates 57 to move in the direction of moving away from or approaching each other on the surface of the cross bar 56. When the two pulley bodies 58 move to the appropriate position, stop rotating the rotating wheel 53. Through the cooperation of the above structure, the position between the two pulley bodies 58 can be adjusted, so that the hole surrounded by the two pulley bodies 58 can be changed, and further can adapt to stretching of different sizes, thereby improving the adaptability of the device.
