A physical training device for physical education according to claim 7, characterized in that: The side ends of the supporting and limiting plate (29) and the connecting crossbar (30) are fixedly connected to the fixed bottom support block (21), and the upper end of the fastening connection frame (15) is fixedly connected to the fixed guide block (3).

9. A physical training device for physical education according to claim 8, characterized in that: A screw is provided on the side of the lower end of the displacement adjustment frame (9), and the displacement adjustment frame (9) is fastened and limited with the lifting handle (11) by means of the screw. The displacement adjustment frame (9) is adjusted laterally on the displacement limiting round rod (10) and the lifting handle (11), and the displacement adjustment frame (9) drives the guide wheel rod (7) and the limiting guide seat (8) to move laterally.

10. A method of a physical training device for physical education, according to claim 9, characterized in that: The following steps are involved: S1. First, a supporting longitudinal platform (35) is fixed on the push-adjusting block (31), and a guide plate (32), a flip seat (33) and a spring hinge rod (34) are arranged on the upper end of the supporting longitudinal platform (35). The user can change the positions of the guide plate (32), the flip seat (33), the spring hinge rod (34) and the supporting longitudinal platform (35) by pushing the push-adjusting block (31), so that the push-adjusting block (31) reaches the central position, and the user can sit on the flipped flip seat (33) to facilitate sitting stretching. The flip seat (33) and the spring hinge rod (34) are symmetrically arranged with respect to the guide plate (32), so that two people can sit at the same time to perform stretching training at both ends. S2. Afterwards, when the sitting pulling is not performed, the push adjustment block (31) can be dragged to both sides to facilitate the standing pulling process. Then, the user plugs the plug block seat (24) and the iron block (25) to adjust the appropriate weight. At the same time, the rope body is wound around the plug block seat (24). The change of the position of the plug block seat (24) can make the movable matching frame (23) move on the vertical pole (22). At the same time, the position of the plug block seat (24) and the movable matching frame (23) on the limiting guard plate (26) is changed. The rope body on the plug block seat (24) can be connected to the matching rotating wheel (5) through the wire wheel block (28); S3, after that, the rope body is connected to the guide wheel rod (7) through the matching rotating wheel (5), and a pulling rod is arranged at the top of the rope body, so that the user can adjust the pulling position, and the displacement adjustment frame (9) can be slidably adjusted on the displacement limiting round rod (10) and the pulling handle (11). After reaching the appropriate position, it can be tightened by the knob screw, so that the displacement adjustment frame (9) and the pulling handle (11) can be positioned, and the guide wheel rod (7), the limiting guide seat (8), the displacement adjustment frame (9), the displacement limiting round rod (10), and the pulling handle (11) are symmetrically arranged, so that the pulling work on both sides can be carried out simultaneously, which is convenient for two people to work together; S4. Finally, a lifting ring (111) is provided at the lower end of the reinforcing plate (6) to facilitate the user to perform pull-up exercises. The side end of the fastening connecting frame (15) is fixed to the fixed side plate (16). The fixed side plate (16) is fixed to the supporting round rod (18) via the supporting stand (17). The user can perform stretching exercises via the supporting round rod (18), which is convenient for performing pull-up exercises.
