Because the threaded hole and the limit groove are in a determined position relationship, when the cutter handle is initially processed, the cutter point of the boring cutter is arranged at an ideal position corresponding to the limit groove in advance, so that the position of the cutter point can be determined by limiting the cutter handle body, the positioning accuracy of the cutter point is not required to be additionally adjusted to the cutter handle, and the efficiency is high.
The axis of the threaded hole is perpendicular to the axis of the cutter handle body.
By adopting the technical scheme: the axis of the threaded hole is perpendicular to the axis of the cutter handle body, so that the force exerted by the fastening screw can be ensured to act on the boring cutter vertically, and the optimal positioning effect is ensured.
The threaded holes are arranged in at least two groups.
By adopting the technical scheme: the boring cutter can be prevented from loosening in the cutter handle by arranging at least two groups of threaded holes, and the positioning effect is prevented from being influenced.
The diameter of the threaded hole is 6mm.
The one end that the handle of a knife body was kept away from the screw hole is equipped with the cylinder, the main shaft hole runs through the cylinder, be equipped with the external screw thread on the cylinder and be used for connecting the screw thread adapter.
By adopting the technical scheme: the water jacket can supply water to the spindle hole to cool the boring cutter.
In summary, the utility model has the following beneficial effects:
1. the relative positions of the main shaft hole and the boring cutter can be determined after the main shaft hole and the boring cutter are assembled, and the positions of the limiting grooves are determined on a machine tool in advance by arranging the limiting grooves to form 180 degrees with the threaded holes, so that the positions of the cutting edges of the boring cutter are ensured.
2. The axis of the threaded hole is perpendicular to the axis of the cutter handle body, so that the optimal positioning effect of the boring cutter is ensured.
3. By arranging at least two groups of threaded holes, the boring cutter is prevented from loosening in the cutter handle, and the positioning effect is prevented from being influenced.

Detailed Description
The utility model is described in further detail below with reference to fig. 1-3.
The embodiment of the utility model discloses a side-fixed boring cutter handle.
Examples:
referring to fig. 1 and 2, the side-fixing boring cutter handle comprises a handle body 1, a main shaft hole 4 for connecting a boring cutter is arranged in the handle body 1, the cross section of the main shaft hole 4 is in a flat circular shape, the main shaft hole 4 is convenient to position after being matched with the boring cutter, a threaded hole 3 communicated with the main shaft hole 4 is further formed in the handle body 1, the threaded hole 3 is used for positioning the boring cutter after being installed in the main shaft hole 4 through a fastening bolt, a limiting groove 2 connected with a machine tool is formed in the handle body 1, and the limiting groove 2 and the threaded hole 3 are arranged at 180 degrees. The boring cutter is arranged in a main shaft hole 4 of a cutter handle body 1 and then is connected with a threaded hole 3 through a fastening bolt, so that the boring cutter is fixed in the main shaft hole 4 by abutting the fastening bolt on the top end of the boring cutter, then is connected with a limiting piece on a machine tool through a limiting groove 2, and the cutter handle is fixed on the machine tool, so that the cutter point of the boring cutter can be rapidly positioned.
As shown in fig. 3, the main body of the main shaft hole and the cutter body of the boring cutter are of flat cylindrical structures, when the main shaft hole and the boring cutter are assembled, the relative positions of the main shaft hole and the boring cutter can be determined, and then the position of the boring cutter can be determined along with the position of the main shaft hole by arranging the limiting groove to form 180 degrees with the threaded hole, so that the position of the cutting edge can be accurately ensured.
The threaded hole 3 and the limit groove 2 are in a determined position relationship, and when the cutter handle is processed initially, the cutter point of the boring cutter is arranged at an ideal position corresponding to the limit groove 2 in advance, so that the position of the cutter point can be determined by limiting the cutter handle body 1, the positioning accuracy of the cutter point is high, and the cutter handle is not required to be additionally adjusted.
