[0009] Further, the clay body shaping device includes a shaping cutter, a cutter holder for fixing the shaping cutter, and a second drive device for controlling the movement of the cutter holder.

[0010] The utility model has the advantages of:

[0011] First: the application is installed on the card jaw slip, forming a high, wide arc of the clamping surface, the rotation of the tubular clay forming protection, to avoid the tubular clay is thrown off or bending deformation.

[0012] Second: the rubber buffer layer is arranged on the inner wall of the slip, so that the slip is not too hard when contacting with the clay, and the clay is not damaged.

[0013] Third: the application sets up the clay shaping device, which cooperates with the clay clamping device to shape the tubular clay in vertical or horizontal state, and the structure is flexible. BRIEF DESCRIPTION OF DRAWINGS
