Flexible swing head device for anastomat

A flexible swing head device for an anastomat is characterized in that the flexible swing head device comprises a flexible mechanism (3) and a swing head pull rod (4); the flexible mechanism (3) comprises a flexible rope (31), a steering bulge (32), two fixed connection points (33) and a plurality of compensation action parts (34); working state, when the swing head pull rod (4) moves along the length direction of the pipe body part (1); the flexible rope (31) is pulled to move around the steering bulge (32); when the jaw part (2) is rotated, the jaw part (2) is driven to swing, when the jaw part (2) and the pipe body part (1) are in a straight line, the flexible rope (31) is in a tensioned state, and when the jaw part (2) is swung and bent, the compensation action part (34) abuts againstthe flexible rope (31) and acts on the flexible rope (31), and the flexible rope (31) is still kept in a tensioned state. The head swinging angle of the jaw part (2) is large and even reaches +/-120 degrees, and the swinging
