At this time, the slide groove disk 9233 fixedly connected to the arc-shaped fixed frame 91 by the rotating connecting shaft 924 remains stationary, so that the inner side of the one-way limit plate 9232 pushes the ball 9236 to move inside the preset slide groove 9234, and the return spring 9235 pushes the ball 9236 to rebound and hit the one-way limit plate 9232 and the groove disk 9231, thereby generating vibration, and then the edge of the double-layer cloth is vibrated and smoothed, further increasing the smoothing effect.
