[0018] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0019] With reference to Figures 1-3 , the water diversion groove anti -entangled chip's hard alloy handle includes hard alloy handle body 1, and the hard alloy handle body 1 includes conical handle part 11, and the outer wall of the conical handle part 11 is equally spaced annular and is provided with six flow guide grooves 111, and the outer wall of the conical handle part 11 is provided with chip breaking flow guide groove 112 at one side of the flow guide groove 111, wherein it is worth noting that the specific structure of hard alloy handle body 1, working principle are the prior art that has been disclosed on the market at present, and do not belong to the main technical problems that need to be solved in the utility model, therefore, the utility model does not add the description.

[0020] And, the conical handle part 11 is conical, and the bottom middle part in the conical handle part 11 is provided with clamping hole 113, wherein the tool required to be used is assembled through clamping hole 113, and the specific structure of clamping hole 113 and hard alloy handle body 1 are the prior art that has been disclosed on the market at present, and do not belong to the main technical problems that need to be solved in the utility model, therefore, the utility model does not add the description.

[0021] Meanwhile, the flow guide groove 111 is arranged obliquely, and the angle between the flow guide groove 111 and the bottom of the conical shank part 11 is 60°, wherein the 60° angle design can make the flow guide groove 111 more effectively guide the chips to be discharged along the tool surface, and help to prevent the chips from accumulating and blocking during the cutting process.

[0022] Meanwhile, the chip breaking flow guide groove 112 is arranged obliquely, and the angle between the flow guide groove 111 and the flow guide groove 112 is 120°, wherein the 120° angle design can reduce the gap between adjacent flow guide grooves, and reduce the accumulation of chips in these gaps, which helps to further improve the chip removal performance and prevent the chips from accumulating and blocking during the cutting process.

[0023] Meanwhile, the provision of the chip breaking flow guide groove 112 provides more discharge channels for the chips, effectively improving the chip removal efficiency. When the chips flow through these chip breaking flow guide grooves 112, they are subjected to gradually increasing extrusion and shearing action, which makes them more likely to break.

[0024] Further, the diameter of the chip breaking flow guide groove 112 on the side close to the flow guide groove 111 is consistent with the diameter of the flow guide groove 111 on the side close to the bottom of the conical shank part 11.

[0025] Further, the flow guide groove 111 on the side close to the bottom of the conical shank part 11 gradually decreases to the other side, and the diameter of the chip breaking flow guide groove 112 on the side close to the flow guide groove 111 gradually decreases to the other side, wherein the gradual decrease in the diameter of the flow guide groove 111 can more effectively guide the chips to be discharged along the preset path, which helps to prevent the chips from accumulating and blocking during the cutting process. At the same time, the decrease in the diameter of the flow guide groove 111 helps to reduce the frictional resistance between the tool and the chips during the cutting process, thereby reducing the cutting temperature and reducing tool wear. The gradual decrease in the diameter of the chip breaking flow guide groove 112 makes it easier for the chips to be discharged when flowing through these grooves, and at the same time reduces the contact area between the tool and the chips during the cutting process, thereby reducing the cutting resistance.

[0026] In this embodiment, the angle between the flow guide groove 111 and the flow guide groove 112 is 120°, which can reduce the gap between adjacent flow guide grooves and reduce the accumulation of chips in these gaps, which helps to further improve the chip removal performance and prevent the chips from accumulating and blocking during the cutting process.

[0027] And, the angle between the flow guide groove 111 and the bottom of the conical shank part 11 is 60°, wherein the 60° angle design can make the flow guide groove 111 more effectively guide the chips to be discharged along the tool surface, and help to prevent the chips from accumulating and blocking during the cutting process.

[0028] Wherein due to the gradually reducing diameter of the flow guide groove 111, the chips can be more effectively guided along the preset path through the flow guide groove 111, which helps to prevent the accumulation and blockage of the chips during the cutting process, and at the same time the reduction of the diameter of the flow guide groove 111 helps to reduce the frictional resistance between the tool and the chips during the cutting process, thereby reducing the cutting temperature, reducing the tool wear, and the gradual reduction of the diameter of the chip breaking flow guide groove 112 makes the chips more easily discharged when flowing through these grooves, while reducing the contact area between the tool and the chips during the cutting process, thereby reducing the cutting resistance.

[0029] In the utility model, the flow guide groove 111 and the chip breaking flow guide groove 112 are arranged on the outer wall of the conical tool shank part 11, so that the chips can be more smoothly discharged along these flow guide grooves during the cutting process, reducing the accumulation and blockage of the chips in the cutting area, and at the same time, the chip breaking flow guide groove 112 provides more discharge channels for the chips, effectively improving the chip removal efficiency, and when the chips flow through these chip breaking flow guide grooves 112, they are subjected to gradually increasing extrusion and shearing action, and are more likely to break.

[0030] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
