[0025] Schematic threading tool

[0026] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, the threading tool has the following structure: Figure 1 As shown, the thread cutter includes a connecting rod 10 and a cutting head 20, the cutting head 20 being fixed on the connecting rod 10 to define the position of the cutting head 20.

[0027] Specifically, the cutting head 20 is arranged perpendicularly to the connecting rod 10, that is, the cutting head 20 is arranged horizontally, and the connecting rod 10 is arranged vertically. The connecting rod 10 also has a mounting groove 101 that penetrates the connecting rod 10, and the cutting head 20 mates with the mounting groove 101, with both ends of the cutting head 20 positioned externally. It is worth mentioning that the bottom wall forming the mounting groove 101 also has a positioning hole 102, with both ends of the positioning hole 102 connecting to the outside and the mounting groove, respectively.

[0028] It should be noted that the thread cutting tool also includes a positioning element 30, which is threadedly connected to the positioning hole 102. That is, the positioning element 30 is used to limit the cutting head 20 by rotating the positioning element 30.

[0029] It is worth mentioning that the structure of the cutting head 20 is as follows: Figure 1 As shown, its end has a cutting end 21, the cutting end 21 has two first inclined surfaces, the two first inclined surfaces are arranged opposite each other and spaced apart by a predetermined distance, and the included angle between the two first inclined surfaces is 55°.

[0030] To facilitate defining the position of the cutting head 20, the surface of the cutting head 20 also has two guide surfaces 211. When the cutting head 20 is engaged with the mounting groove 101, one of the guide surfaces 211 is in contact with the wall of the mounting groove 101, and the other guide surface 211 is directly opposite the positioning hole 102 and spaced at a predetermined distance from the positioning hole 102. That is, the positioning member 30 can directly abut against the guide surface 211 to define the position of the cutting head 20, and the guide surface 211 is a plane.

[0031] It is worth mentioning that the intersection of the two first inclined surfaces of the thread cutting tool forms a tip 212. The tip 212 has a plane, which is triangular in shape. That is, the plane can be machined by an external grinding wheel, i.e., part of the wall of the tip 212 abuts against the external grinding wheel to form a triangular plane.

[0032] It should also be noted that the threading tool has an arc surface 213 and a flat surface 214. The arc surface 213 is connected to the flat surface 214, and the end of the arc surface 213 facing away from the flat surface 214 is connected to the end of the cutting head 20. The protruding length of the cutting end 21 is 2.7 cm.

[0033] It should be noted that, to facilitate the installation of the aforementioned cutter head 20, this application also provides, as follows: Figure 3The installation embodiment shown is as follows. Specifically, the guide surface 211 facing the positioning hole 102 also has an open limiting groove 201, and the opening of the limiting groove 201 communicates with the outside. The wall surface forming the mounting groove 101 and providing the positioning hole 102 also has two guide portions 100, which are arranged opposite each other and spaced a predetermined distance apart. The positioning hole 102 is located between the two guide portions 100. Notably, both guide portions 100 are slidably engaged with the limiting groove 201, and both guide portions 100 are also configured to support the cutting head 20, thereby limiting the position of the cutting head 20. Simultaneously, when the wall surface forming the limiting groove 201 and facing away from the opening contacts the guide portion 100, the movement direction of the cutting head 20 is limited, thus defining the position of the cutting head 20. It should be noted that the bottom wall forming the limiting groove 201 also has a limiting hole 202. The limiting hole 202 is located between the two guide parts 100 and is directly opposite the positioning hole 102. That is, when the cutter head 20 is engaged with the two guide parts 100, the positioning hole 102 is directly opposite the limiting hole 202, and the size of the positioning hole 102 is larger than the size of the limiting hole 202. At the same time, the end of the positioning member 30 facing the limiting hole 202 also has a protrusion 31. The protrusion 31 is configured to engage with the limiting hole 202, that is, the movement of the cutter head 20 is limited by the protrusion 31.

[0034] In summary, the threading tool described in the embodiments of this application is explained, which provides advantages such as ease of use, convenient tool changing, and high practicality.

[0035] It is worth mentioning that, in the embodiments of this application, the threading tool has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the threading tool provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
