[0002] The processing and shaping of wooden boards requires a large number of cutting tools. Cutting tools are tools used for cutting processes in mechanical manufacturing, also known as cutting tools. The vast majority of cutting tools are machine-made, but some are hand-made.

[0003] Chinese Patent CN205668308U discloses a cutting mechanism on a wood cutting device. The cutting mechanism includes cutting tools disposed on both sides of a feeding track and a rotary motor driving the cutting tools to rotate. The cutting tools are used to cut the side of the wood within the feeding mechanism, forming tenons along the feeding path. This cutting mechanism uses cutting tools to process the side of the wood, creating tenons along the feeding path; it not only simplifies the processing structure and reduces production costs but also improves processing efficiency.

[0004] However, the above structure is equipped with only one type of cutting tool, which is relatively simple in function and cannot meet the requirements of multiple production specifications.

The locking assembly locks the third R-cutter 4 of the outer tool assembly, and the second R-cutter 3 of the intermediate tool assembly is in the retracted state. The motor spindle of the machine tool power head drives the spindle sleeve 1 to rotate. The first R-cutter 2 and the third R-cutter 4 of the outer tool assembly are processed.

[0077] The output end of the first cylinder 30 does not contact the outer cylinder 7 of the locking assembly. The first spring 26 pushes the outer cylinder 7 to move towards the motor spindle of the machine tool power head. The outer cylinder 7 drives the moving seat 8 to move towards the motor spindle of the machine tool power head. When the moving seat 8 drives the V-groove 22 to move to the outside of the inclined block 20, the compression spring between the insert blocks 19 drives the insert blocks 19 to be in an active state. The output end of the second cylinder 31 moves to contact the second fixing ring 14 of the intermediate tool assembly, pushing the second fixing ring 14 of the intermediate tool assembly to move. The second fixing ring 14 drives the second R-tool connecting cylinder 15 to move.

R-cutter 2 is flush with the first insertion hole 24 and is directly opposite the insertion block 19. The restoring force of the compression spring between the insertion blocks 19 drives the insertion block 19 to move outward into the first insertion hole 24. The insertion block 19 and the first insertion hole 24 cooperate to lock the second R-cutter 3 of the intermediate tool assembly. The driving end of the third cylinder 32 does not contact the first fixing ring 10 of the outer tool assembly. The restoring force of the third spring enables the third R-cutter 4 to move towards the motor spindle of the machine tool power head. The ends of the second R-cutter 3 and the first R-cutter 2 of the intermediate tool assembly that are away from the motor spindle of the machine tool power head are flush with the first fixing ring 10 of the outer tool assembly. The motor spindle of the machine tool power head drives the spindle sleeve 1 to rotate. The second R-cutter 3 and the first R-cutter 2 of the intermediate tool assembly rotate to perform simultaneous processing.
