[0038] Work flow: when the drill bit cutting assembly 1 is worn to a certain extent, the drill bit cutting assembly 1 is replaced, the whole device is dispersed by disassembling the mounting head 42, the worn drill bit cutting assembly 1 is taken out, and the intact drill bit cutting assembly 1 is installed. First, the first square plate 12 and the second square plate 13 are aligned with the embedded groove 25 and slid into the embedded groove 25. When the bottom end of the drill bit cutting body 11 is attached to the top end of the drill bit body 21, the drill bit cutting body 11 is rotated. When the second square plate 13 is clamped into the clamping groove 26, there is a certain gap between the first square plate 12 and the embedded groove 25. The side of the first square plate 12 close to the second square plate 13 is flush with the side of the first square recess 23 close to the embedded groove 25. Then the rectangular baffle 45 is aligned with the second square recess 33 respectively and slid upward. When the threaded rod 41 is attached to the second threaded hole 32, the mounting head 42 is rotated by a tool to drive the threaded rod 41 to rotate. When the lower end of the rectangular baffle 45 is about one centimeter away from the upper end of the second square recess 33, the first square recess 23 opened in the drill bit body 21 is aligned with the rectangular baffle 45. During the process, the positions of the second external thread 35 and the first external thread 22 need to be determined to ensure that the second external thread 35 and the first external thread 22 are in communication after installation. After the rectangular baffle 45 is slid into the first square recess 23, the mounting head 42 is rotated again to drive the threaded rod 41 to rotate. When the threaded rod 41 rotates, the limiting rotating column 44 is rotatably connected in the double column groove 43. The arrangement of the limiting rotating column 44 and the double column groove 43 does not affect the upward movement of the rectangular baffle 45, and at the same time prevents the rectangular baffle 45 from being separated from the threaded rod 41. When the rectangular baffle 45 is attached to one side of the first square plate 12, the position of the first square plate 12 and the second square plate 13 can be limited to prevent the drill bit cutting assembly 1 installed on the drill bit body assembly 2 from being separated.

When the mounting head 42 is in the booster groove 34, the installation is completed. The fixing device 4 temporarily fixes the drill bit body assembly 2 and the drill bit external assembly 3. When the whole device is connected with the drill rod, the second external thread 35 on the drill bit external body 31 and the first external thread 22 on the drill bit body 21 are in the drill rod. This arrangement further increases the strength of the device. When the drill bit is replaced, the drill bit body assembly 2 and the drill bit external assembly 3 do not need to be replaced at the same time, which reduces the use cost and improves the competitiveness. The replaced drill bit cutting assembly 1 has high strength, which ensures that the operation efficiency of the drill bit is not affected.
[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
