This utility model is had the advantages that by the operation to push rod, the compression between axle sleeve and ringfeder
Spring a can partial offset push rod thrust upwards it is ensured that ringfeder produces suitable thrust to squeeze pin, it is to avoid because thrust is excessive
And cause to clamp the phenomenon of the quality of excessive influence workpiece；Slided by the drive end of the inwall of extruded sleeve and elastic jacket and join
Close, and compression spring b between extruded sleeve and elastic jacket, during moving on extruded sleeve, extruded sleeve passes through pressure
Contracting spring b produces thrust upwards to elastic jacket, due to the shaft shoulder located at elastic jacket bare terminal end and located at pedestal upper surface
The cooperation of limiting plate limit moving up of elastic jacket, but due to being applied to the continuous action of the thrust of extruded sleeve, from
And producing the radial thrust to elastic jacket, elastic jacket is realized inwardly tightening up, thus realizing the clamping to workpiece centre position；
In the case that the thrust being applied to extruded sleeve is excessive, compression spring b is in compressive state, the therefore compression spring under this state
B equally can offset the thrust of part, prevents the extruding force that extruded sleeve bare terminal end applies to elastic jacket bare terminal end excessively, this clamping
Device has the characteristics that clamping effect is good and clamping force is moderate.
