Specific embodiment
It is that the features described above of the present invention and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing, make in detail
Carefully it is described as follows, but the present invention is not limited to this.
With reference to Fig. 1 and Fig. 3, a kind of nut breaks and cuts device, including u-shaped bearing 1, on the medial surface of described u-shaped bearing one side
It is provided with the conical socket 11 for laying nut one side, described nut can be hex nut or tamper nut, described u-shaped props up
It is provided with the screwed hole contour with nut centrage, described screw thread in the hole is connected with horizontal swivel nut 2, described on the other side of seat
Horizontal cutter shaft 3 is installed in horizontal swivel nut, the movable end of described horizontal cutter shaft is provided with and cuts another side of nut for stirring
While can be with the blade of convenient replacing, the diameter 31 of described movable end is more than the diameter 32 of cutter shaft, and movable end is near knife
Plane Ball bearing 4 is provided with and horizontal swivel nut between on the side of axle connecting portion to prevent the outside side of horizontal cutter shaft from deviating from,
Reduce the frictional force between horizontal axle sleeve and horizontal cutter shaft, described horizontal cutter shaft stretches out and is provided with the peripheral part of horizontal swivel nut simultaneously
Screw thread, the stop nut be made up of through the locking nut 5 in horizontal swivel nut end face outside or two nuts and horizontal swivel nut
Realize axially position.
In the present embodiment, disassembling, assembling and replacing cutter head 6 for convenience, cutter head and horizontal cutter shaft are releasable connection, break sharpener simultaneously
Using carbide drill, can be by the replacing of cutting edge, for cutting plain nut and the anti-theft nut of various models.
The blade of cutter head is used for stirring cuts another side of nut, and the cutter head edge of described horizontal cutter shaft is placed in horizontal cutter shaft front end
In clip slot 33, described clip slot setting is tapered, and described taper is 1 ° ~ 2 °, so that dismounting cutter head, described clip slot periphery falls into and is placed in spiral shell
