[0018] The technical scheme in the utility model application will be described clearly and completely below in conjunction with the drawings in the utility model application. Obviously, the described application is only a part of the application, not the whole application. Based on the application in the utility model, all other applications obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] Refer to Figure 1 , Figure 2 The utility model discloses a kind of oxygen sensor thread repair tools:

[0020] As shown in Figure 1 , Figure 2 The utility model discloses an oxygen sensor thread repair tool, including handle part 1 and the main body structure of extension setting below handle part 1, the main body structure includes the cutting structure 3 of extension setting below handle part 1, multiple chip grooves 2 are set on cutting structure 3, the lower side of cutting structure 3 is connected with guide structure 4, the lowermost end circle on cutting structure 3 is shovel cutting edge 5;The bottom center of guide structure 4 is provided with calibration hole 401, and the center of handle part 1 is provided with center hole 101.

[0021] Specifically, the cutting structure 3 is arranged below the shank 1, and a plurality of cutting edges are uniformly arranged on the cutting structure 3. The lowermost cutting edge of the cutting structure 3 is a chisel cutting edge 5, and the angle between the cutting edge and the horizontal line is 45°. In this way, the oxygen sensor thread repair tool has a transition tapping stage when re-tapping the thread, and the thread is not irreversibly damaged due to the sudden addition of the cutting edge. The cutting edge can gradually cut the thread during rotation to achieve accurate repair of the thread. The guide structure 4 is connected below the cutting structure 3, and the cross-sectional shape of the guide structure 4 is circular. In this way, the guide structure 4 can be smoothly guided into the thread, ensuring the smooth progress of the repair process.

[0022] Further, the cross-sectional shape of the shank 1 is a regular hexagon. In this way, the shank 1 not only provides a stable gripping feeling, but also enables the shank 1 to maintain a stable rotation trajectory during rotation, improving the repair accuracy. The size of the shank 1 is M13, which can ensure the convenience of operation. The center of the shank 1 is provided with a center hole 101, and the bottom center of the guide structure 4 is provided with a calibration hole 401. The center line of the center hole 101 coincides with the center line of the calibration hole 401. In this way, the tool can be positioned and calibrated, further improving the repair accuracy. The material of the oxygen sensor thread repair tool is high-speed steel, which has good wear resistance and hardness, and can maintain a sharp cutting edge for a long time, prolonging the service life of the tool. The chip groove 2 is uniformly arranged on the cutting structure 3, and the number of chip grooves 2 is six. In this way, the cutting force can be uniformly distributed to improve the cutting efficiency.

[0023] Further, the cutting knives on the cutting structure 3 are uniformly distributed to form multiple cutting edges. In this way, the cutting process is more stable, and the thread damage caused by uneven cutting force is avoided. The shape of the cutting edge can be selected as a straight line or an arc according to actual needs to adapt to the repair needs of different thread shapes and improve the versatility and flexibility of the tool.

[0024] Further, a plurality of chip grooves 2 are arranged on the cutting structure 3. The cross-section of the chip groove 2 has the structural feature that the upper bottom edge is short and the lower bottom edge is long. In this way, the chips can be smoothly discharged during the cutting process, avoiding the interference of chip accumulation on the cutting effect, and improving the cutting efficiency and repair quality. The shank 1, the cutting structure 3 and the guide structure 4 are integrally formed. In this way, the overall strength and stability can be improved, and the assembly error in the manufacturing process can be reduced to improve the manufacturing accuracy of the tool.

[0025] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
