In the preferred embodiment, a support bar 11 is provided on the frame 10, the support bar 11 extending in the same direction as the sliding direction of the tightening machine. Since the tightening machine has a small bottom space and it is difficult to directly mount the friction wheel 30 on the bottom of the tightening machine, the link frame 40 is mounted on the bottom of the machine frame 10. The friction wheel 30 is hung below the support bar 11 through the connecting frame 40, and the friction block 20 is arranged corresponding to the extending direction of the support bar 11. This link 40 is square frame, and the first end of link 40 is articulated with support bar 11, and the second end of link 40 freely extends, and the second end of link 40 is articulated with the both ends of friction pulley 30, and link 40 can drive friction pulley 30 towards or keep away from support bar 11 free movement like this.
