When the user is physically overdrawn and unable to pull the weight block 6 during training, the stopping mechanisms provided at both ends of the weight block 6 for protecting the user are utilized to prevent the weight block 6 in the limiting frame 5 from falling rapidly, thereby causing the user's legs to be pulled up. This solves the problem that in the use of traditional physical training equipment, beginners cannot have a clearer understanding of their own physical fitness, and are prone to overdrawing their physical strength during training, resulting in the training equipment losing its strength support and falling rapidly, causing physical harm to the user.

[0029] In this embodiment, a cable 12 is arranged on the top of the weight block 6, so that the cable 12 passes through the roller 11 arranged on the top of the limiting frame 5 and is inserted to the other side. A connector 13 is arranged at one end of the cable 12 away from the weight block 6. When it is necessary to perform double-arm stretching exercises, a traction rope is installed on the connector 13, and the traction rope is pulled to drive the cable 12, thereby pulling the weight block 6 arranged at one end for exercise. When it is necessary to perform leg stretching exercises, a forked cable 14 is arranged at one end of the connector 13, so that the forked cable 14 can be pulled to move the weight block 6 arranged at one end. One end of 14 is connected to the leg stretching plate 4, so that when the user sits on the folding chair 3, the legs are continuously opened and closed, thereby pulling the forked cable 14, driving the weight block 6 set at one end of the cable 12 for training.

[0030] Example 4
[0031] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, a limiting groove 17 is opened at the center of the top of the base 1, and a support plate 18 is inserted into the inner wall of the limiting groove 17, and one end of the support plate 18 is rotatably connected to the bottom of the folding chair 3.
[0032] In this embodiment, the folding chair 3 is pulled to pull out the support plate 18 provided at the bottom of the folding chair 3 , and a limiting groove 17 is provided at the center of the top of the base 1 , and the support plate 18 is inserted into the limiting groove 17 , thereby adjusting the angle of the folding chair 3 .
[0033] The following is a detailed description of the working principle of the stretching equipment used for physical training.
[0034] like Figure 1-4As shown, by arranging a cable 12 on the top of the weight block 6, the cable 12 passes through the roller 11 arranged on the top of the limiting frame 5 and is inserted to the other side. By arranging a connector 13 at one end of the cable 12 away from the weight block 6, when it is necessary to perform double-arm stretching exercises, by installing a traction rope on the connector 13, the traction rope is pulled to drive the cable 12, thereby pulling the weight block 6 arranged at one end for exercise. When it is necessary to perform leg stretching training, a forked cable 14 is arranged at one end of the connector 13, and one end of the forked cable 14 is connected to the leg stretching plate 4. By arranging a rotating shaft 2 at one end of the top of the base 1, A folding chair 3 is arranged on the top of the rotating shaft 2. By pulling the folding chair 3, the support plate 18 arranged on the bottom of the folding chair 3 is pulled out. By arranging a limiting groove 17 at the center of the top of the base 1, the support plate 18 is inserted into the limiting groove 17 to adjust the angle of the folding chair 3. When the user sits on the folding chair 3, the forked cable 14 is pulled by the legs to drive the weight block 6 arranged at one end of the cable 12 for training. By arranging a limiting box 15 at the center of the bottom of the base 1, a limiting block 16 is arranged on the inner wall of the limiting box 15, and the inner wall of the limiting block 16 is aligned with the outer wall of the forked cable 14. The invention relates to a method for connecting a weight block 6 to a wall, which solves the problem that the bifurcated cable 14 is deviated due to the uncoordinated legs of the user during training, thereby causing unnecessary safety hazards. By arranging blockers 7 at both ends of the weight block 6, and the limit rods 10 arranged at both ends of the inner wall of the limit frame 5 slide on the inner wall of the blocker 7, when the user is physically exhausted and the weight block 6 falls rapidly, since the blocker 7 is made of silicone rubber, which has strong elasticity and toughness, the inner wall of the blocker 7 wraps the outer wall of the limit rod 10. Since the inside of the blocker 7 is filled with a non-Newtonian fluid, when the inner wall of the blocker 7 is twisted, the limit rod 10 is twisted. When the rod 10 is wrapped, the non-Newtonian fluid is stimulated to harden, thereby achieving support for the weight block 6. At the same time, the weight block 6 is started to move away from the electric telescopic rods 8 arranged at both ends of the blocker 7, so that the neoprene block 9 arranged at the output end of the electric telescopic rod 8 clamps the limit rod 10, thereby further increasing the friction between the weight block 6 and the limit rod 10, solving the problem that in the process of using traditional physical training equipment, beginners cannot have a clearer understanding of their own physical fitness, and thus easily overdraw their physical strength during training, causing the training equipment to lose strength support and fall rapidly, causing physical harm to the user.
[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
