Segmented thread sections on the spindle allow coupling bodies to engage specific pitches, eliminating time-consuming rotation for different workpiece sizes.
A clamping tool damper absorbs push rod displacement through friction to prevent explosive release.
Vertically inclined hole spaces in mounting blocks enable half-turn locking of jawplates, eliminating time-consuming screw rotations.
Integrated base body contact surfaces eliminate complex support blocks, resolving the trade-off between centering precision and device complexity.
