When the telescopic frame is specifically implemented, the telescopic adjusting effect of the telescopic frame can be realized through the following scheme: the square tube with smaller size is selected as the telescopic frame for installing the hook foot assembly, the square tube with larger size is installed on the main support frame 11 as the telescopic frame base of the positioning telescopic frame, one end of the telescopic frame is inserted into the telescopic frame base, and the telescopic frame can be movably adjusted forwards and backwards. Offer the expansion bracket bolt hole of in-band screw thread on the expansion bracket base, correspond the expansion bracket bolt hole and be equipped with the expansion bracket bolt of outband screw thread, accomplish the adjustment back of colluding foot subassembly position through adjustment expansion bracket 10 position, screw up the expansion bracket bolt in the expansion bracket bolt hole, thereby expansion bracket 10 is blocked by the expansion bracket bolt and can not remove and be fixed on the main tributary strut. The position of the foot hooking component 1 is adjusted according to different statures of users, so that the rotation angle of the back cushion component 5 in the training process can be controlled in a proper range.

In order to avoid leading to drawing the subassembly to cause uncontrollable influence because collude foot subassembly 1 back-and-forth adjustment, optimize the relevant position of drawing the subassembly: the telescopic rod 10 is provided with a first pulley 22, a second pulley 23 is arranged in the main support frame 11 at a position adjacent to the telescopic rod 10, a third pulley 24 which forms a triangular structure with the first pulley 22 and the second pulley 23 is arranged between the first pulley 22 and the second pulley 23, the first pulley 22 and the third pulley 24 are connected through a first adjusting plate 25, the second pulley 23 and the third pulley 24 are connected through a second adjusting plate 26, and the traction rope 8 is sequentially wound on the first pulley 22, the third pulley 24 and the second pulley 23. When the hook foot component 1 is adjusted back and forth, the first pulley 22 fixed on the telescopic rod 10 will move back and forth along with the first pulley and cause the third pulley 24 to move, as shown in fig. 4, wherein a in fig. 4 represents the state before adjustment, and b the telescopic frame extends forwards and is adjusted. However, during the moving process, the length of the part of the traction rope 8 wound on the first pulley 22, the third pulley 24 and the second pulley 23 is always kept to be approximately equal to the sum of the lengths of the first adjusting plate 25 and the second adjusting plate 26, so that the adverse effect of the front and back adjustment of the foot hooking assembly 1 on the traction assembly is avoided.
