Further, the termination of the taper shank is provided with safe blind rivet.
Further, the taper shank is standard BT50 Morse taper shanks.
Further, multiple annular grooves are offered in the side wall of the clamping hole.
Further, axially equidistantly arrangement of the annular groove along the clamping hole.
Further, it is described extend handle of a knife length for 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm or 500mm.
Further, any one in a diameter of φ 3mm- φ 32mm of the clamping hole.
Compared with prior art, advantageous effects of the present utility model are as follows:
The utility model drives hydraulic cavities piston to move inwards, extrudes hydraulic oil, increase oil by screwing hydraulic pressure jackscrew Pressure, so as to which clamping cutter, clamping power are big;Conversely, unscrew hydraulic pressure jackscrew, then loosening cutter;It convenient and swift can operate and change cutter, The elastic of hydraulic pressure jackscrew need to be only twisted with die nut, you can realize release and the locking function of cutter, greatly reduce behaviour Make person works' intensity, greatly improve operating efficiency, shock resistance and can improve work pieces process quality;
Hydraulic pressure handle of a knife head coordinates with extending handle of a knife, can change random length, realizes that overlength handle of a knife is processed;Hydraulic pressure handle of a knife head with Extend cooperation of the handle of a knife by key and keyway, prevent hydraulic pressure handle of a knife head from being relatively rotated with extending handle of a knife, and by bolt from ladder It is tightened onto in hole in screwed hole, prevents hydraulic pressure handle of a knife head from axially being disengaged with extending handle of a knife, stable connection.
