When air is supplied by an air pressure regulation part to bellows 211 through 213 of finger joint motion facilitation parts 110j (where j=1, . . . , 5), the bellows 211 through 213 expand approximately in the shape of circular arcs, since annular grooves on the side of the bellows 211 through 213 opposing a joint are elastically restrained by elastic members 241 through 243. Due to this, the bellows 211 through 213 cooperate, and exert force in the rotational direction to flex the first through the third joints of a finger from their extended states. Next, when air is exhausted from the bellows by the air pressure regulation part, the bellows 211 through 213 contract. Due to this, the bellows 211 through 213 cooperate, and exert force in the rotational direction to extend the first through the third joints of a finger from their flexed states. The forces generated in this manner are transmitted to the joints by transmission members 231 through 234. As a result mounting becomes simple, and also it is possible to facilitate sufficient joint movement for each joint.

The invention relates to the technical field of knitwear treatment equipment, in particular to a knitting open-width continuous ultrasonic scouring system which comprises a pretreatment box, a tail treatment box is arranged on one side of the pretreatment box, a scouring box is connected between the pretreatment box and the tail treatment box, a conveying mechanism is arranged in the pretreatment box, and a loosening mechanism is arranged at the bottom end of the conveying mechanism. A heating mechanism is arranged at the bottom end of the relaxation mechanism; through the arrangement of the conveying mechanism, the staying time of the cloth in the pretreatment box can be prolonged, and more redundant treatment time is provided for the relaxation mechanism and the heating mechanism; by arranging the loosening mechanism, the knitted fabric can be conveyed without tension, and the cloth seal and gram weight of the finished cloth are guaranteed; through the arrangement of the boiling mechanism and the wriggling mechanism, the wriggling effect is simulated while the knitted fabric is conveyed, the chemical reaction effect between liquid and the fabric is better, the reaction can be more effectively promoted in cooperation with the ultrasonic assembly, and the quality of the finished fabric is improved.
