The connecting end 336 extends out of the casing 31 after passing through the opening 312, and the positioning block 335 restricts the positioning of the connecting end 336 to the casing. In addition, in this embodiment, the fitness equipment 4 has an action end 41 , and the action end 41 is connected with the connection end 336 .

Referring to FIG. 2 and FIG. 3 , when the present embodiment operates, after the controller 322 controls the driving motor 321 to rotate, the driving motor 321 will drive the transmission belt 331 to link, and the transmission belt 331 will link the link wheel. 332 rotates, and the interlocking wheel 332 will link the force-bearing wheel 333 to rotate during the rotation process. At this time, the force-bearing belt 334 wound on the force-bearing wheel 333 will be affected by the force-bearing wheel 334. 333 is rotated and rolled down, and at the same time, because the end of the force-bearing belt 334 is restricted by the positioning block 335, the force-bearing belt 334 will be in a tensioned state, so that the force-bearing wheel 333 is fixed by the force-bearing belt 334, together with The interlocking pulley 332 , the transmission belt 331 and the driving motor 321 are in a stopped state. When the controller 322 continues to control the output torque of the driving motor 321 , the output torque of the driving motor 321 will be maintained constant, and the force will be The belt 334 is subjected to the pulling force of the driving motor 321 relative to the torque force, and the pulling force can be used as the negative gravity required for fitness. Therefore, the controller 322 controls the driving motor 321 to output the torque force, which can be easily and quickly . Accurately adjust the weight load required for fitness, without the need to adjust the conventional way of increasing or decreasing the weight block. Therefore, in addition to reducing the overall volume and use space of the weight load device 3, it can also avoid the known weight load during the action process. The noise of blocks rubbing against each other or being placed is generated.
