A fixed block 508 is fixedly connected, and the outer sides of the fixed blocks 508 on the left and right sides are rotatably connected with a rotating shaft 509. A mounting sleeve 510 is arranged on the outer side of the rotating shaft 509. A collecting roller 511 is fixedly connected between the mounting sleeves 510 on the left and right sides. The left and right sides of the collecting roller 511 are provided with mounting grooves 513, and the mounting grooves 513 are threadedly connected to the mounting sleeves 510.
