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.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of rotating cutting tool being conveniently replaceable, including
Cutter main frame body 3 offers bearing connection through-hole 4 inside cutter main frame body 3, be angularly fixed with outside cutter main frame body 3 to
Few 4 extension fixed frames 1, and extend 1 side of fixed frame and be connected with cutter support plate 9,9 bottom end of cutter support plate and cutter body frame
3 surface of body is fixedly installed togather, this structure enables user that can extend the fixed different number of fixed frame 1 according to the needs of use
Vane body 5, change the precision of the material of crushing to facilitate according to the quantity of vane body 5,9 top surface of cutter support plate with
Extend 1 side of fixed frame to be mutually perpendicular to, and 9 top surface of cutter support plate and 5 bottom surface of vane body are seamless applying, this structure makes knife
Tool 9 top surface of support plate can be against 5 bottom surface of vane body completely, be supported to 5 bottom surface of vane body, to avoid the occurrence of knife
5 bottom surface of piece main body and 3 cambered surface of cutter main frame body are only the case where line contacts, and enhance the bearing capacity of this cutter entirety, and bearing connects
Connection hole 4 is hexa-prism structure, and bearing connection 4 axis of through-hole is overlapped with 3 axis of cutter main frame body, this structure makes bearing
Connection through-hole 4 is in the center of cutter main frame body 3, and the rotation of bearing the connection through-hole 4 and hexa-prism of hexa-prism structure
Bearing can be reduced when linking together there is the case where cutter rotation, is fixed with outside cutter main frame body 3 and extends fixed frame 1,
Extend and be uniformly provided with 3 fixed frame mounting holes 8 inside fixed frame 1, extends and taken vane body 5, and blade on the right side of fixed frame 1
6,3 fixed frame mounting hole 8 and 3 knives of tool mounting hole corresponding with 8 position of fixed frame mounting hole are offered inside main body 5
Through being equipped with cutter standing screw 7 inside tool mounting hole 6, cutter standing screw 73 at the helicitic texture of extension end be interior
Helicitic texture, and the maximum gauge of extension end is equal to tool mounting hole 6 and fixed frame mounting hole 8 at the 3 of cutter standing screw 7
Diameter, this structure make at the 3 of cutter standing screw 7 extension end when through insertion tool mounting hole 6 and fixed frame mounting hole 8
Will not interference due to helicitic texture by tool mounting hole 6 and fixed frame mounting hole 8, and stretched out at the 3 of cutter standing screw 7
