Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of cutter for avoiding inner hole fillet from interfering, packet Include knife handle 1, link block 2, mounting groove 3, mounting rod 4, handle 5, connection knife bar 6, the knife edge 7, buffer stopper 8 and convex block 9, the knife handle 1 side is provided with connection knife bar 6, and the buffer stopper 8 is set to the connection one end of knife bar 6 far from knife handle 1, wherein

The knife handle 1 is fixed with link block 2 far from the vertical plane of connection knife bar 6, and the link block 2 is set to the company of knife handle 1 End is connect, the shape of the link block 2 is equilateral triangle structure, and the middle line of link block 2 is overlapped with the central axes of knife handle 1, even It connects block 2 to be directly connected with external equipment, at work, cutter passes through high speed rotation to cutter, and link block 2 is in external equipment Inside will not rotate, and guarantee the phenomenon that cutter will not be not in loosening with the connection of external equipment；

The mounting groove 3 is located at the same side of knife handle 1, the inside dimension and mounting rod 4 of the mounting groove 3 with link block 2 External dimensions match, and mounting rod 4, altogether there are two settings, and mounting rod 4 is symmetrically disposed on the two sides of knife handle 1, installation Mounting rod 4, is directly directly buckled in 3 inside of mounting groove for mounting rod 4, and mounting groove 3 directly overlays mounting rod 4 far from handle 5 Lower surface, hand, which exerts a force to handle 5, can drive the direction of rotation of the cutter, facilitate force, easy to operate, the installation Slot 3 is set to knife handle 1 close to the side of connection knife bar 6, and the mounting groove 3 is equipped with mounting rod 4, institute far from the side of knife handle 1 It states mounting rod 4 and is connected with handle 5 far from one end of mounting groove 3；

The knife edge 7 is that helicitic texture is looped around connection vertical plane of the knife bar 6 far from knife handle 1, and the section of the knife edge 7 is " recessed " type structure, " recessed " the type structure of the knife edge 7 reduce the thickness of the cutting edge of the knife edge 7, increase directly by 7 surface of the knife edge to point The cutting tooth bud quantity of the knife edge 7, will not influence the hardness of the knife edge 7, increases the sharpness of cutting, accelerates the speed of cutting, subtracts The small working time increases working efficiency, is fixedly connected between the connection knife bar 6 and the knife edge 7, the convex block 9 is fixed on slow The one end of block 8 far from connection knife bar 6 is rushed, the buffer stopper 8 is frustum cone structure, and the axis of the central axes of buffer stopper 8 and convex block 9 Line is overlapped, and convex block 9 is cylindrical structure, and buffer stopper 8 is different from the smoothing tool used originally, in the process of work, Buffer stopper 8 will not be contacted with the equipment cut is needed, and directly reserved the region of inner hole fillet interference, made the cutter in cutting The case where avoiding the occurrence of the interference of inner hole fillet in the process.

Working principle: when using the cutter for avoiding inner hole fillet from interfering, firstly, the outside that the cutter is mounted directly When on device, the link block 2 of knife handle 1 is directly connect with external equipment, link block 2 is directly buckled in external equipment when installation Jointing on, due to link block 2 be equilateral triangle structure, when in use, cutter pass through high speed rotation, knife Tool will not be loosened with external equipment, when arranging maintenance cutter, when can not find cutter, can directly drag handle 5, will The mounting rod 4 of handle 5 is directly buckled in 3 inside of mounting groove and more convenient can dismantle in the two sides of cutter while rotating handle 5 Or the cutter is installed, when cutter work, connection knife bar 6 drives the knife edge 7,9 high speed rotation of buffer stopper 8 and convex block, knife Cutting edge of a knife or a sword 7 at work, since the knife edge 7 is " recessed " type structure, reduces the thickness of the cutting edge of the knife edge 7, increases the cutting of the knife edge 7 The speed of tooth bud quantity, cutting is accelerated, and working efficiency is increased, and simultaneous buffering block 8 will not directly be set with what needs were cut with convex block 9 Standby contact will not carry out large area work to the equipment that needs are cut, directly reserve the region of inner hole fillet interference, make the knife Tool avoids the occurrence of the case where inner hole fillet interference during cutting, and the content being not described in detail in this explanation belongs to ability The prior art well known to the professional technician of domain.
