Fig. 12 is a schematic perspective view of a tension adjusting member according to another embodiment of the present invention. As shown in fig. 12, the difference between this embodiment and the first and second embodiments is the tension adjusting member, and other components are the same as the corresponding components mentioned in the above embodiments, which are not described herein again, and the following describes in detail the different tension adjusting members in this embodiment.

Referring to fig. 12, the tension adjusting member includes a clutch, the clutch includes an outer ring 411 and an inner ring 412, a hydraulic cylinder is connected to an outer periphery of the inner ring 412, the hydraulic cylinder includes a hydraulic cylinder 414 and a piston 417 located in the hydraulic cylinder 414, an outer end of the piston 417 is connected to a spring 416, an outer end of the spring 416 is connected to a clutch ball 413, and the clutch ball 413 abuts against an inner end of the outer ring 411.

The hydraulic cylinder 414 is filled with hydraulic oil from an external hydraulic oil supply device, a spring 416 is connected between a hydraulic piston 417 and a clutch ball 413, the clutch ball 413 and the piston 417 are both arranged inside the hydraulic cylinder 414, the tail of the hydraulic cylinder 414 is communicated to a hydraulic oil loop 415 in the inner ring 412, and the hydraulic oil loop 415 is communicated to the external hydraulic oil supply device.

The hydraulic oil pushes the piston 417 to move along the hydraulic cylinder 414, when the pressure of the hydraulic oil supplied from the outside is increased, the hydraulic oil pressure in the hydraulic cylinder cavity is increased, the piston 417 is pushed to move towards the outer ring 411, the spring 416 is squeezed, the spring 416 squeezes the piston 417 connected to the tail of the clutch ball 413, and the outer edge of the clutch ball 413 squeezes the outer ring 411 to play a supporting role.
