You can sit on the seat cushion 1051 for tension training. If you need to adjust the height of the pull ring 3046, rotate the crank 3027. The crank 3027 rotates under force to rotate the bevel gears B3025 on both sides, and the outer wall of the bevel gear B3025 The gear on the top is meshed with the gear on the outer wall of the bevel gear A3024. Therefore, the rotation of the bevel gear B3025 will drive the bevel gear A3024 to rotate. The rotation of the bevel gear A3024 drives the top threaded rod B3021 to rotate, and the outside of the outer wall of the threaded rod B3021 An external thread is provided, and the external thread on the outer wall of the threaded rod B3021 is engaged with the internal thread in the threaded hole wall on the end face of the moving block 3023. Therefore, when the threaded rod B3021 rotates, the moving block 3023 will be driven upward or downward. movement, which can drive the pull ring 3046 to move upward or downward to achieve the purpose of adjusting the position and height of the pull ring 3046, and adjust it according to the height of the user. After the adjustment is completed, use both hands to pull the pull rings 3046 on both sides, and exert force Pull outward and repeat this to exercise your arm strength. If you need to adjust the pulling strength, insert the limit rod 3034 on the outside of the fixed block 3033 into the channel 3047. At this time, the end of the limit rod 3034 will contact the limiter. The inclined surface of the block 30512 contacts and continuously exerts force on the limit block 30512. The limit block 30512 is forced to move into the channel 3047 and compresses the spring 30511. When the limit block 30512 is completely moved upward, the limit rod 3034 is inserted, and then The force of the limit block 30512 disappears, and the spring 30511 rebounds to eject the limit block 30512 and insert it into the slot 3035 on the limit rod 3034, so that the strong tension spring 3032 can be fixed on the pull plate 3045, thereby achieving increased For the purpose of tensile strength, if you need to reduce the tensile strength, press the pressure plate 3056 inward, and the pressure plate 3056 will move inward under the force, thereby driving the rocker 3055 to move inward, and rotate under the action of the rotating shaft 3053, which will also compress the torsion spring. 3054, then the other end of the rocker plate 3055 is lifted up to pull up the limit plate B3058 through the pull rope 3057, and the limit plate B3058 is connected to the limit block 30512 through the connecting rod C30510, so when the limit plate B3058 moves up, the connection Rod C30510 drives the limit block 30512 to move and compresses the spring 30511, so that the limit block 30512 moves out of the slot 3035, and the limiting effect disappears. Then pull out the limit rod 3034 to remove the strong tension spring 3032. In order to reduce the tensile strength, during the training process, both hands pull the pull ring 3046 to drive the pull plate 3045 to move outward. The pull plate 3045 is forced to drive the strong tension spring 3032 at the rear to extend, and at the same time, the connecting rod B3044 is driven inwards of the U-shaped tube 3041. Move outward, and the pull plate 3045 is connected to the rubber plug 3043 through the connecting rod B3044. Therefore, when the pull plate 3045 is stressed, the rubber plug 3043 will move outward with the connecting rod B3044, and the outer wall of the rubber plug 3043 is in contact with the U-shaped tube. The inner wall of 3041 is tightly fitted. Therefore, in order to ensure the air pressure balance in the U-shaped cylinder 3041, the air in the external environment will enter the U-shaped cylinder 3041 through the trachea 3042. When the force is stopped, the strong tension spring 3032 Under the action of the pulling force, the pulling plate 3045 will be driven back to the original position, and during the pulling process, the rubber plug 3043 will be driven to move to the inside of the U-shaped cylinder 3041 through the connecting rod B3044, and the air inside the U-shaped cylinder 3041 will be compressed. Therefore, like this The setting can slow down the pulling force of the strong tension spring 3032 after people's force disappears and act as a protective device. At the same time, it can also play a protective role to prevent the strong tension spring 3032 after people suddenly lose strength due to fatigue. If the pulling force is large, it will suddenly retract. After training, ice packs and cushions 1051 can be used to dissipate heat and rest.
