The specific embodiment

As shown in Figure 1, the present invention rotates Shave tool, comprises the BT handle of a knife 2 of taper, and the rear end of BT handle of a knife 2 is fixedly installed blind rivet 1, and the front end of BT handle of a knife 2 is fixedly connected with adapter sleeve 3;

BT handle of a knife 2 is the conical surface with the mating surface of adapter sleeve 3, and the inner cone of BT handle of a knife 2 matches with the outer cone of adapter sleeve 3;

Adapter sleeve 3 is realized locking with BT handle of a knife 2 by attaching nut 6 and is connected;

In adapter sleeve 3, be movably set with ER standard knife bar 4; Adapter sleeve 3 is realized and being flexibly connected of ER standard knife bar 4 by sliding bearing 5; The cylindrical of sliding bearing 5 matches with the endoporus of adapter sleeve 3; The end face of adapter sleeve 3 is fixedly connected with and is integral by attachment screw 7 with sliding bearing 5;

The front end of ER standard knife bar 4 stretches out from regulating sleeve 9, and the front end of ER standard knife bar 4 is provided with ER elastic clip cylinder 10; ER elastic clip cylinder 10 is for clamping revolving scraper 14 as shown in Figure 2; By ER locking nut 11, realize being fixedly connected with of ER standard knife bar 4 and revolving scraper 14;

The rear end of ER standard knife bar 4 is radially fixedly equipped with slidiing pin 12, and the two ends of slidiing pin 12 prop up the inner hole wall of adapter sleeve 3; Slidiing pin 12 can be in the interior activity of adapter sleeve 3;

ER standard knife bar 4 can drive the slidiing pin 12 on it to slide vertically in sliding bearing 5; The stroke that endwisely slips of ER standard knife bar 4 is determined by the axial scope of activities of slidiing pin 12;
