[0034] The use method is detailed as follows: first, pull up the ring 3 to make the inserting rod 713 of the ring 3 slide out of the positioning hole of the top rod 2, at this time, the distance between the two rings 3 can be adjusted, after the distance is adjusted, the ring 3 is reinserted into the positioning hole of the top rod 2 by the inserting rod 713. Then, the driving rod 705 is rotated, the driving rod 705 drives the block 706 to move by the thread at this time, the block 706 slides in the limiting frame 702, so as to realize the effect that the maximum stroke of the sliding block 711 in the limiting frame 702 is adjusted, when the appropriate position is adjusted, the rotation of the driving rod 705 is stopped, at this time, the preparation operation is completed, for different classes and different age groups of students, each class or each grade of students only needs to be adjusted once.

[0035] At this time, two students can use the equipment in cooperation, the student who needs to train pull-ups stands on the pedal 6, the anti-skid pad 714 on the pedal 6 prevents the student from slipping, then the student can directly hold the top rod 2 with both hands, the other student stands on the ground, the student on the ground can hold the handle 708 with both hands, when the student performs pull-ups, the student on the ground can pull down the pull rod 707 by force, and the direction of the pulling force is converted into the upward stretching of the pedal 6 by the fixed pulley 4, so as to assist the student in pull-ups, when the pulling rope 5 slides through the fixed pulley 4, the pulling rope 5 drives the positioning block 703 to slide in the limiting frame 702, when the student on the ground unloads, the arms of the student who performs pull-ups begin to stretch, the positioning block 703 slides upward along the limiting frame 702, when the student on the ground suddenly releases his hand because of lack of strength, at this time, the positioning block 703 quickly slides in the limiting block 712, and the positioning block 703 collides with the block 706, so as to limit the falling stroke and also can brake in an emergency.

[0036] In view of the fact that the ground students are physically weak, the hook 81 can be hung on the pull rod 707, and then the pressing rod 82 is rotated and screwed into the inner side of the hook 81, and then the cover plate 84 is pulled open, the counterweight is put into the storage box, and then the cover plate 84 is closed. At this time, when the ground students pull the pull rod 707 to assist the students doing pull-ups, the gravity of the counterweight can be used to assist the assistance.
