It is of the present utility model to have technical effect that：This extracting tool is without impulsive force, and dismounting is steady, safety labor-saving, Ke Yigen
According to the overhang of the adjustment wedge of different gap size, this instrument does not allow wedge-shaped block directly to be contacted with taper-shank cutter,
But allow above single wedge be in contact with it, worn and torn it is rear directly change wedge, and without changing entirety, reduce and use into
This；The outer-hexagonal nut of welding handle can be pulled easily with hand, easy to use without being pulled looking for spanner.
Brief description of the drawings
Fig. 1 is the structural representation of taper shank link；
Fig. 2 is the sectional view of taper shank extracting tool use state of the present utility model；
Fig. 3 is the dimensional structure diagram of drive block of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, a kind of extracting tool of taper shank 5, includes the drive block of a tabular, and the drive block has half
Cylindrical side 41, and the cammed surface 42 set with the semi-cylindrical side 41 into angle；The semi-cylindrical side 41 with
The mutually close one end of cammed surface 42, which is extended, a threaded rod 43, the axis of the threaded rod 43 and the axle of semi-cylindrical side 41
Line is parallel；Also include constituting the nut 3 that screw thread coordinates with the threaded rod 43；When dismantling taper shank 5, the drive block is interspersed in cone
In waist-shaped hole 11 in handle connecting rod 1, wherein the circle of the semi-cylindrical side 41 and one end away from taper shank 5 in waist-shaped hole 11
Cambered surface is fitted, and the end that the cammed surface 42 is located at the taper shank 5 in waist-shaped hole 11 is pushed against, and the threaded rod 43 protrudes out to waist
Outside type hole 11, the aperture gear of the nut 3 and waist-shaped hole 11 connects.This extracting tool is without impulsive force, and dismounting is steady, and safety is saved
Power.This provision for disengagement is fitted by semi-cylindrical with the semicircular inner walls of waist-shaped hole 11, and produces using the binding face dismounting
The reaction force of taper shank 5, its contact area is big, and unit area pressure is smaller, is difficult to cause the inwall of waist-shaped hole 11 damage.
It is preferred that, the drive block includes tapered wedges 7 and wedge block 4, with the end of taper shank 5 on the wedge block 4
