In cap 52, so the collet 51 can be allowed when tightening the external screw thread chuck nut 52 along 312 small-bore of the first taper guide hole
Direction moves, while can also reach the effect for locking the collet 51.
By 51 one end taper of collet and 312 taper of the first taper guide hole be arranged to identical, identical taper can carry out it is good
Good assembling, so as to improve the concentricity of assembling.The cap aperture of external screw thread chuck nut 52 is the second taper guide hole 522, this second
Taper guide hole 522 is more than the aperture far from 10 one end of main shaft mounting portion close to the aperture of 10 one end of main shaft mounting portion, and collet 51 is another
One end taper is identical with the second taper 522 tapers of guide hole, which has certain guiding role, convenient
The installation of the collet 51, and identical taper can further improve the concentricity of assembling.
Guide groove 3111 is set in 311 bottom surface of internal thread hole, which is located on the first taper guide hole 312, outside
Screw thread chuck nut 52 is provided with the guide ring 521 coordinated with the guide groove 3111 close to one end of main shaft mounting portion 10, passes through
The cooperation of the guide ring 521 and the guide groove 3111 can cause external screw thread chuck nut 52 to be more easy to assemble.By in the first cone
312 bottom of shape guide hole setting endoporus clearance position 313, which is provided with internal thread (not shown), the internal thread spiral shell
Line is connected with limiting head part 314；The limiting head part 314 is used for limiting and withstanding cutter 9 so that the cutter 9 is installed tighter
Gu by controlling the position of the limiting head part 314 in endoporus clearance position 313, the cutter 9 can be adjusted and stretch out grinding engraving handle of a knife
Length, the use for the person of being convenient to use.
In addition, grinding engraving handle of a knife can also install multi-disc grinding wheel 8, such as install a piece of rough grinding wheel 8 and a piece of essence
Grinding abrasive disk 8 can be carried out at the same time corase grinding and fine grinding in this way, reduce processing step, improve production efficiency；Grinding wheel 8 it
Between the gasket 91 of high flatness and cylindricity is set, it is different for carrying out more 8 stations of grinding wheel press fittings and separating, and pass through to replace
Thickness and the gasket of size 91 can be adapted to all kinds of abrasive wheels 8, and the nut 41 that is preferably locked of grinding wheel 8 can be enable to lock.
Special spanner 7 as shown in Figure 5, including handle 71 and annular surface 72, which fixes with the annular surface 72
Connection, is provided with several raised 721 to match with several blind holes 523 on the annular surface 72, and the annular surface 72 is for allowing cutter 9
It is pierced by, convenient for the dismounting of external screw thread chuck nut 52；Directly being engaged with several raised 721 by several blind holes 523 just can be right
External screw thread chuck nut 52 is dismounted, and several blind holes 523 and several raised 721 making are all very convenient, can reduce system
Cause this.
The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
