[0003] Chinese patent CN214831182U discloses a dye jigger, which includes a dye jigger body, a dye jigger trough is provided in the dye jigger body, a first cloth guide roller and a second cloth guide roller are fixedly connected in the dye jigger trough, a first cloth pulling rod is rotatably connected to the two inner side walls of the dye jigger trough, two second cloth pulling rods are connected between the two first cloth pulling rods, and a positioning member for positioning the inclination angle of the first cloth pulling rod is provided on the dye jigger body. The tension state of the cloth can be controlled by rotating the first cloth pulling rod. However, the dye jigger still has the following problems: The dye in the dye tank will be concentrated at the place where the dye is added.
