Description

Technical Field

[0001] The present application relates to the technical field of cutting bit assemblies, and more particularly to a cutting bit assembly. Background Art

[0002] As the name suggests, the cutter head is the head of the tool, which can be divided into diamond cutter heads, alloy cutter heads, and carbon steel cutter heads. They are resistant to high temperatures, wear-resistant, and sharp. They are essential products for hardware processing, lathe processing, and stone processing. With the advancement of technology, cutter head products are also changing with each passing day and new products are constantly being launched.

[0003] According to the search, the Chinese patent with publication number CN219188654U discloses an easily replaceable cemented carbide cutting head, which includes a cutting head, a mounting groove, a cutting blade, a bolt and a threaded groove. A cutting blade is arranged at the end of the cutting head, and a mounting groove is provided on the surface of the cutting blade on one side of the cutting head. A bolt passes through the middle of the cutting blade, and the end of the bolt is sleeved in a threaded groove provided on the surface of the mounting groove. A plurality of groups of spring grooves are provided inside the cutting head. When replacing the cutting blade, the operator is no longer required to pull the cutting blade to pull the cutting blade out of the mounting groove, thereby improving the convenience of the operator in replacing the cutting blade. At the same time, the spring pushes the connecting ring, so that the connecting ring pushes the receiving groove to move through the push rod, thereby preventing the receiving groove from pushing the cutting blade to move all the time, thereby improving the stability of the operator in installing the cutting blade.

[0004] Regarding the above-mentioned related technologies, the applicant believes that they are only applicable to the pushing out of the cutting blade installed on the surface of the cutting bit, but not applicable to the pushing out of the cutting blade installed inside the cutting bit. Therefore, we propose a cutting bit assembly. Utility Model Content
