30512 is stressed and then disappears, the spring 3051 rebounds to eject the limiting block 3052 and inserts the limiting block 3055 into the clamping groove 3035 on the limiting rod 3034, so that the powerful tension spring 3032 can be fixed on the pulling plate 3045, the purpose of increasing the tensile strength can be achieved, if the tensile strength is required to be reduced, the pressing plate 3056 is pressed inwards, the pressing plate 3056 is forced to move inwards, the rocker 3055 is driven to move inwards and rotate under the action of the rotating shaft 3053, the torsion spring 3054 is compressed, then the other end of the rocker 3055 is lifted to pull the limiting plate B3058 up through the pull rope 3055, the limiting plate B3058 is connected with the limiting block 30512 through the connecting rod C30510, therefore, the limiting block 3053 is driven to move through the connecting rod C30510 and compress the spring 3053 when the limiting plate B3058 moves upwards, the limiting block 3052 is moved out of the clamping groove 3035, the limiting effect is eliminated, the powerful tension spring 3032 is removed after the limiting rod 3034 is pulled out, the purpose of reducing the tensile strength is achieved, in the training process, the pull ring 3046 is pulled by both hands to drive the pull plate 3045 to move outwards, the pull plate 3045 is stressed to drive the rear powerful tension spring 3032 to extend, meanwhile, the connecting rod B3044 is driven to move outwards in the U-shaped cylinder 3041, the pull plate 3045 is connected with the rubber plug 3043 through the connecting rod B3044, therefore, when the pull plate 3045 is stressed, the rubber plug 3043 moves outwards along with the connecting rod B3044, the outer wall of the rubber plug 3043 is tightly attached to the inner wall of the U-shaped cylinder 3041, in order to ensure the air pressure balance in the U-shaped cylinder 3041, air in the external environment enters the U-shaped cylinder 3041 through the air pipe 3042, and when the force application is stopped, the pull plate 3045 is driven to be pulled back to the original position under the action of the powerful tension spring 3032, and in the pulling process, the rubber plug 3043 is driven to move inwards in the U-shaped cylinder 3041 through the connecting rod B3044, and the air in the U-shaped cylinder 3041 is compressed, so that after the force application of people is lost, the tension of the powerful tension spring 3032 can be slowed down, the effect of a protection device is achieved, meanwhile, the protection effect can be achieved after people lose force suddenly due to fatigue, the powerful tension spring 3032 is prevented from retracting suddenly when the tension is large, and after training is finished, the ice bag and the cushion 1051 can be used for heat dissipation and rest.

The foregoing is only a preferred embodiment of the present invention, and the present invention is not limited thereto, and any modification, equivalent replacement, and improvement of some of the technical features described in the foregoing embodiments are all within the scope of the present invention.
