[0006] The tip includes a support portion and a conical portion, the support portion being located in the central region, and the bottom surface of the conical portion contacting the side of the support portion away from the first surface;

[0007] A reinforcing part is provided in the annular region and surrounds the supporting part, and the reinforcing part has a protrusion that mates with the groove.

[0008] Furthermore, the support portion shown is cylindrical, and the axis of the support portion extends along the first direction.

[0009] Furthermore, the support portion and the conical portion are an integral structure.

[0010] Furthermore, the groove is annular and surrounds the central region; the protrusion is annular and mates with the groove.

[0011] Furthermore, the tip and the reinforcing part form a conical structure.

[0012] Furthermore, the main body includes a first main body and a second main body, both of which are frustum-shaped. The bottom surface of the first main body is in contact with the bottom surface of the second main body. The first surface is the surface of the first main body away from the second main body, and the second surface is the surface of the second main body away from the first main body. Along the direction away from the first main body, the cross-section of the second main body gradually decreases. Along the direction away from the second main body, the cross-section of the first main body gradually decreases. The tip, the reinforcing part, and the first main body constitute a conical structure.

[0013] Furthermore, the first main body, the second main body, and the top tip are an integral structure, and the reinforcing part is detachably connected to the main body.

[0025] This disclosure provides a tip structure. The tip structure may include a main body 1, a tip 2, and a reinforcing part 3, wherein:

[0026] The main body 1 may include a first surface 103 and a second surface 104 opposite to each other in a first direction. The first surface 103 may include a central region 1031 and an annular region 1032 surrounding the central region 1031. The annular region 1032 is provided with a groove 1033. The tip 2 may include a support portion 202 and a conical portion 201. The support portion 202 may be disposed in the central region 1031 of the first surface 103, and the bottom surface of the conical portion 201 contacts the side of the support portion 202 away from the first surface 103. The reinforcing portion 3 may be disposed in the annular region 1032 of the first surface 103 and surround the support portion 202. The reinforcing portion 3 may be provided with a protrusion 301 that mates with the groove 1033. The material of the reinforcing portion 3 is diamond.

[0027] In this embodiment of the tip structure, the reinforcing part 3 can be assembled to the main body part 1 through the cooperation of the protrusion 301 and the groove 1033, so that the reinforcing part 3 surrounds the support part 202, thereby improving the strength and wear resistance of the tip 2. The reinforcing part 3 can be made of diamond, which further enhances the strength and wear resistance of the tip 2.

[0028] The top structure of the embodiments of this disclosure will now be described in detail:

[0029] The main body 1 may include a first surface 103 and a second surface 104 opposite to each other in a first direction. In the first direction, the main body 1 may include a first body 101 and a second body 102. The first body 101 may be frustum-shaped, cylindrical, or prismatic, but this disclosure is not limited thereto. The second body 102 may also be frustum-shaped, cylindrical, or prismatic, but this disclosure is not limited thereto. Taking the first body 101 and the second body 102 both as frustum-shaped as an example, the bottom surface of the first body 101 contacts and adheres to the bottom surface of the second body 102. The first surface 103 of the main body 1 is the surface of the first body 101 away from the second body 102, and the second surface 104 of the main body 1 is the surface of the second body 102 away from the first body 101. The height of the first body 101 may be greater than the height of the second body 102, or the height of the first body 101 may be less than or equal to the height of the second body 102. The first body 101 and the second body 102 can be separate structures bonded together, or they can be an integral structure. The first body 101 and the second body 102 can be made of the same material, such as iron or an iron alloy. The first surface 103 can include a central region 1031 and an annular region 1032 surrounding the central region 1031. The central region 1031 can be circular, and the annular region 1032 can be annular. The annular region 1032 has a groove 1033. The groove 1033 can be annular and surround the central region 1031.

[0030] The tip 2 may include a support portion 202 and a conical portion 201. The support portion 202 may be located in the central region 1031 of the first surface 103. In one embodiment, the support portion 202 is cylindrical, and its axis extends along a first direction, i.e., the height direction of the support portion 202 is the first direction. In another embodiment, the support portion 202 is frustum-shaped, its axis extends along the first direction, and its cross-section gradually decreases along the direction away from the main body 1. The bottom surface of the conical portion 201 contacts the side of the support portion 202 away from the first surface 103. Further, the side of the support portion 202 may be provided with a protruding ridge. The width direction of the protruding ridge may be perpendicular to the first direction. The extension trajectory of the protruding ridge is a straight line. The cross-section of the protruding ridge may be an inverted trapezoid, but this disclosure is not limited to this; the cross-section of the protruding ridge may also be rectangular, etc.

[0031] The reinforcing part 3 can be disposed in the annular region 1032 of the first surface 103 and surround the support part 202. The reinforcing part 3 can be provided with a strip-shaped groove that mates with the protruding edge, and the material of the reinforcing part 3 is diamond. The protruding edge and the strip-shaped groove slide together to allow the reinforcing part 3 to be assembled with the support part 202, enhancing the hardness of the tip 2 and increasing its wear resistance. The tip 2 and the reinforcing part 3 form a conical structure. Furthermore, the tip 2, the reinforcing part 3, and the first body 101 also form a conical structure. The first body 101, the second body 102, and the tip 2 are an integral structure, and the reinforcing part 3 is detachably connected to the tip 2. Moreover, since the cross-section of the protruding edge is an inverted trapezoid, the reinforcing part 3 can be more securely assembled with the support part 202. The reinforcing part 3 can be provided with a protrusion 301 that mates with the groove 1033. The protrusion 301 can be annular and mates with the groove 1033. In addition, the end of the annular protrusion 301 is provided with a protrusion 3011 extending along the first direction, and the bottom surface of the groove 1033 is provided with a recess 10331 that mates with the protrusion 3011.

[0032] The aforementioned protruding ridges and strip grooves are both multiple, with each protruding ridge corresponding to one of the multiple strip grooves, and the multiple protruding ridges are distributed along the circumference of the support portion 202. Alternatively, two protruding ridges may be present, and the two protruding ridges are evenly distributed along the circumference of the support portion 202.

[0033] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure in any way. Although this disclosure has been disclosed above with reference to a preferred embodiment, it is not intended to limit this disclosure. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this disclosure. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this disclosure without departing from the content of the technical solution of this disclosure shall still fall within the scope of the technical solution of this disclosure.
