         4 . The cuffing tool holding device of  claim 1 , wherein the arc receiving post has an arc lead angle of an end. 
     
     
         5 . The cutting tool holding device of  claim 1 , wherein the guiding block has at least one guide slant surface, the guide slant surface corresponding to the cutting tool. 
     
     
         6 . The cutting tool holding device of  claim 5 , wherein the guiding block has a plurality of guide slant surfaces, the guide slant surfaces are gradually reducing heights from an inside of the guiding block to an outside of the guiding block. 
     
     
         7 . The cutting tool holding device of  claim 6 , wherein the guiding block is a triangular prism-shaped. 
     
     
         8 . The cutting tool holding device of  claim 1 , wherein each of the embedding portion and the embedding concave is a triangular ingot-shaped. 
     
     
         9 . A cutting tool holding device for holding a cutting tool, the cutting tool holding device comprising:
 a base having a front rake wall, a back rake wall, and a positioning hole, the front rake wall having an embedding portion, and the back rake wall connected to the front rake wall, wherein the back rake wall has an arc, receiving hole and the positioning hole is communicated with the arc receiving hole, and the arc receiving hole has two abutted surfaces;   a holder mounted on the base for receiving the cutting tool, the holder having a main body, an arc receiving post, and a guiding block, the main body having a first abutting portion and a second abutting portion, the first abutting portion having a first abutting surface and an embedding concave, the first abutting surface abutted against the front rake wall, and the embedding portion detachably embedded into the embedding concave, the second abutting portion having a second abutting surface, and the second abutting surface abutted against the back rake wall, the arc receiving post extending projecting from the main body, wherein the arc receiving post is correspondingly set into the arc receiving hole, and a position limiting groove is formed on the arc receiving post corresponding to the positioning hole, and the arc receiving post has at least two side surfaces and the two side surfaces are abutted against the two abutted surfaces, and the guiding block is projected corresponding to the cutting tool; and   a fastening member fastened in the positioning hole and pressed against the position limiting groove.   
     
     
         10 . The cutting tool holding device of  claim 9 , wherein the base has two centering inside surfaces, and that each is inward incline, and the holder has two centering outside surfaces that each is outward incline. 
     
     
         11 . The cutting tool holding device of  claim 9 , wherein each of the arc receiving post and the arc receiving hole has a cross section shape being drop-shaped. 
     
     
         12 . The cutting tool holding device of  claim 9 , wherein each of the arc receiving post and the arc receiving hole has a cross section shape being heart-shaped. 
     
     
         13 . The cutting tool holding device of  claim 9 , wherein the arc receiving post has an arc lead angle of an end.
