Being set with sealing ring on groove, described sealing ring uses axle YX shape sealing ring.
Described crust of the device includes that shell body, the center of described shell body are machined with through hole, the lateral symmetry of described through hole
Being machined with a piston hole and No. two piston holes, the both sides of described through hole are machined with valve mounting apertures, described support piston rod set
Being contained in inside a piston hole and No. two piston holes, described valve mounting apertures is communicated with oiling passage, described oiling channel connection
A number piston hole and No. two piston holes.
Hydraulic oil is had by piston rod packing inside a described piston hole and No. two piston holes.
This utility model has the advantages that:
By promoting two support piston rod effects with tool rest rear portion thus to fix cutter toward the internal hydraulic oil that injects of device
Sheet, in work produce pulling force when piston compression make interior oil pressure raise thus absorb in work produce pulling force protection
Bolt will not loosen or break.
