[0002] Cutting tools are tools used for cutting in mechanical manufacturing. Most of the tools are machine tools, but there are also hand tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as metal cutting tools.

[0003] For example, the utility model with application number CN202321315294.8 discloses a combined cutting tool. The utility model combines a handle rod, a cutter head rod and an anti-deflection mechanism to further limit and fix the position of the cutter head rod without affecting the cutting process of the workpiece by the cutting head, and supports and shares the torque force on the cutter head rod, thereby preventing the cutter head rod from deflecting and loosening and affecting the fine processing of the workpiece by the cutting head, increasing the stability of the cutting head and improving the processing accuracy. However, during the processing of the workpiece, the structure of the cutting head may cause chip splashing, which is not conducive to the normal cutting work.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a cutting tool capable of controlling the chip flow direction is proposed. Utility Model Content

A first slide bar 708 is connected to the right side of the bottom of the movable seat 707, and the rear end of the first slide bar 708 is connected to the first swing bar 709 through a rotating shaft. A second sliding seat 710 is arranged at the front end of the second screw nut 706, and a second slide bar 711 is connected to the left side of the top of the second sliding seat 710, and the rear end of the second slide bar 711 is connected to the second swing bar 712 through a rotating shaft. The forward and reverse rotating screw rods 702 and the driving member 703 are coaxially arranged, the knife body 1 and the end seat 704 are fixedly connected, the forward and reverse rotating screw rods 702, the first slide bar 708 and the second slide bar 711 are parallel to each other, the first sliding seat 707 and the second sliding seat 710 move in opposite directions, the first slide bar 708 runs through the sliding groove on the surface of the second sliding seat 710, and the second slide bar 711 runs through the sliding groove on the surface of the first sliding seat 707, and the surface of the guide portion 6 is respectively connected to the first swing bar 709 and the second swing bar 712 through a rotating shaft, and the first swing bar 709 and the second swing bar 712 are parallel to each other.

[0022] The specific operation is as follows: use an external hexagonal wrench to tighten the driving part 703 to rotate the forward and reverse rotating screw 702, so that the first screw nut 705 and the second screw nut 706 move in opposite or opposite directions along the outside of the forward and reverse rotating screw 702, and change the supporting angle of the first slide bar 708 and the second slide bar 711 to the first swing bar 709 and the second swing bar 712, so that the guide part 6 that controls the chip flow direction is offset, thereby achieving the effect of directional chip removal.

[0023] like Figure 2 As shown, a cutting bit 2 is installed at the bottom of the cutter body 1, and an air inlet channel 3 is provided inside the cutter body 1, a cold air outlet head 4 is installed inside the air inlet channel 3, and the top of the cold air outlet head 4 is a frustum structure.

[0024] The specific operation is as follows: the air inlet end of the air inlet channel 3 is connected to the air source to take air. After the compressed air enters the air inlet channel 3, it will be affected by the cold air outlet head 4 with a reduced diameter to accelerate the flow speed, thereby spraying the low-temperature gas to the cutting head 2, so that the cutting head 2 can be cooled faster, preventing the cutting head 2 from deformation or even breakage, and avoiding the problem of chips sticking to the tool.

[0025] In summary, when the cutting tool capable of controlling the flow direction of chips is used, firstly, the end of the guide portion 6 close to the cutting head 2 is designed in a stepped manner, which can guide the flow direction of chips during the fine processing of the workpiece, so that the waste chips under cutting avoid the processing surface of the workpiece. As the cutting head 2 processes the workpiece, the compressed air enters the cold air outlet head 4 from the air inlet channel 3 to the processing part, blowing away the chips and taking away the heat generated by cutting, so that the cutting head 2 cools down faster, which is beneficial to prolonging the service life of the tool.

[0026] Since the guide part 6 is rotatably connected to the cutter body 1 through the rotating rod 5, when the chip flow direction needs to be adjusted, the driving part 703 is screwed with the help of a common tool, an external hexagonal wrench, and the driving part 703 provides a rotational force for the forward and reverse rotating screw 702, so that the first screw nut 705 and the second screw nut 706 can respectively drive the first sliding seat 707 and the second sliding seat 710 to make opposite or opposite displacements in the vertical direction, and the first sliding rod 708 and the second sliding rod 711 respectively fixed to the first sliding seat 707 and the second sliding seat 710 change the support angle of the first swing rod 709 and the second swing rod 712, so that the guide part 6 rotates, thereby achieving the effect of controlling the chip flow direction.

[0027] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
