There is advantages that the present invention when die sinking, namely when lock tooth because of rotation lock die sleeve
Cylinder and when departing from lockhole, the oblique top portion that locked mode sleeve is arranged slips into described planar portions along the skewback portion of gland,
And then make locked mode sleeve rearward displacement one distance receive the instantaneous impulse of lockhole to reduce the lock tooth when die sinking, with
Time the application promote two locked mode sleeves by locked mode cylinder, save the usage amount of cylinder, and lock
The concordance rotated between die sleeve cylinder is more preferable.
