Described first contact surface is provided with the clamping raised line that cross section is circular arc, and the second contact surface is provided with the clamping groove that cross section is circular arc, the central angle f=130 ° that the circular arc of clamping groove is right, described clamping raised line and clamping groove matched in clearance;

The inwall of described first die sleeve and the second die sleeve is respectively provided with in one and regulates passage, and the outer wall of the first die sleeve and the second die sleeve is respectively equipped with two and regulates passage outward, and described interior adjustment passage and outer adjustment passage are interspersed.

The utility model beneficial effect is:

1. the utility model adopts split-type structural, can direct splicing formula be linked in die shank outside, in order to increase the external diameter of die shank, structure is simple, and highly versatile, has saved cost;

2. the first contact surface and the second contact surface be arranged in parallel, and the angle c=130 ° between the tangent line of the first contact surface and the first die sleeve, and when two contact surfaces contact with each other, laminating is relatively tightr, can not slippage easily, ensure that its stability;

3. the angle d=90 ° between the tangent line of the first clearance plane and the first clearance plane, angle e=90 ° between the tangent line of the second clearance plane and the second clearance plane, after can ensureing that two die sleeves are bonded to each other, clearance plane can not contact with each other, leave certain cushion space, therefore in use can not cause damage because of other factors such as vibrations, add service life;

4. the first contact surface is provided with the clamping raised line that cross section is circular arc, second contact surface is provided with the clamping groove that cross section is circular arc, and both cooperatively interact, and namely can ensure the flatness that both are bonded to each other, there is again certain surplus, the die shank of different size can be applicable to;

5. regulate being crisscross arranged of passage and outer adjustment passage in, add buffer capacity to a certain extent, add service life.
