However, in the present embodiment, the rotation of the mandrel is realized by pushing the toggle rod 516 through the abutting rotation device, and the rotatable abutting relationship between the special-shaped groove and the abutting rotation device needs to be ensured, so that the abutting rotation device is rotatably abutted against the mandrel.
