Referring to fig. 4, the rotating assembly includes a mounting sleeve 21 fixed on the frame 100, a rotating shaft 22 fixed on the end of the driving bending member 1, and a driving motor 23 for driving the rotating shaft 22 to rotate; the rotating shaft 22 is fixedly connected with the output end of the driving motor 23; the driving motor 23 is fixedly installed on the frame 100, and the rotating shaft 22 is sleeved in the installation sleeve 21. When the driving bending member 1 rotates, the driving motor 23 is started, and the output end of the rotating driving motor 23 drives the driving bending member 1 to rotate by a predetermined angle through the rotating shaft 22 (the predetermined angle is limited as described below).

Referring to fig. 7 and 8, a plurality of accommodating grooves 11 for accommodating press blocks 2 are formed in the driving bending piece 1, and the press blocks 2 are hinged in the accommodating grooves 11; the pressing block 2 is of a fan-shaped structure.
