[0016] The present invention provides Figure 1-7 The easily replaceable annular groove cutter shown comprises a mounting handle 1, a clamping mechanism and a connecting mechanism, wherein the clamping mechanism is arranged at one end of the mounting handle 1, and the connecting mechanism is arranged on a side wall of the clamping mechanism at a position opposite to the mounting handle 1; The clamping mechanism includes an extension rod 2 and a cutter head mounting block 4, the cutter head mounting block 4 is detachably connected to the extension rod 2, the top and bottom of the extension rod 2 are fixedly connected to the limiting rod 3 near the middle position of the left side, the front side and the rear side of the extension rod 2 are each provided with a placement groove 13 near the middle position of the left side, and a limit assembly is provided in each of the two placement grooves 13 and the two limit assemblies are symmetrically arranged, the limit assembly includes a telescopic rod 22, a reset spring 21, a fixing plate 18, an L-shaped block 11, and a second bolt 10, a fixing hole 20 is opened in the middle of the placement groove 13, the fixed end of the telescopic rod 22 is fixedly connected to the fixed wall in the fixing hole 20, one side of the fixing plate 18 is fixedly connected to the movable rod of the telescopic rod 22, and the other side of the fixing plate 18 is fixedly connected to the connecting wall of the L-shaped block 11, the reset spring 21 is sleeved on the telescopic rod 22, one end of the reset spring 21 is fixedly connected to the fixed wall in the fixing hole 20 and the other end is fixedly connected to the fixing plate 18; An inserting cavity 15 matching the extension rod 2 is provided on the right side of the cutter head mounting block 4, a sliding groove 16 matching the limiting rod 3 is provided at the top and bottom of the inserting cavity 15, limiting grooves 12 matching the protruding end of the L-shaped clamping block 11 are provided at both ends of the inserting cavity 15, and a clamping groove 17 is provided on the outer wall of the cutter head mounting block 4 away from the opening end of the inserting cavity 15 on the two limiting grooves 12, and the two clamping grooves 17 are respectively communicated with the corresponding limiting grooves 12, and the clamping groove 17 matches the protruding end of the L-shaped clamping block 11; The connecting mechanism comprises a connecting block 9 and a mounting member 6 , wherein the connecting block 9 and the mounting member 6 are detachably connected, and a blade 8 is provided on the mounting portion of the mounting member 6 , and the blade 8 and the mounting member 6 are detachably connected.

[0017] When the cutter head mounting block 4 needs to be installed on the extension rod 2, the operator presses the L-shaped blocks 11 on both sides of the extension rod 2 to press the connecting wall of the L-shaped block 11 into the placement groove 13. At this time, the telescopic rod 22 contracts, and the return spring 21 is squeezed by the L-shaped block 11 and contracts into the fixing hole 20, and then the protruding end of the L-shaped block 11 is aligned with the limiting groove 12 on the insertion cavity 15 in the cutter head mounting block 4. At this time, the limiting rod 3 on the extension rod 2 is aligned with the slide groove 16 in the insertion cavity 15, and the extension rod 2 is pushed into the insertion cavity 15. The limiting groove 12 limits the L-shaped block 11, and the slide groove 16 limits the limiting rod 3 to prevent the extension rod 2 from deviating during the pushing process. When the L-shaped block 11 is placed in the protruding wall and moves to the position coincident with the slot 17, the L-shaped block 11 loses the limit of the limiting groove 12, and the return spring 21 rebounds to drive the protruding end of the L-shaped block 11 to snap into the slot 1 7, limit the extension rod 2, and then screw the second bolt 10 into the second bolt hole 14, further limit the L-shaped block 11 to prevent loosening, and the cutter head mounting block 4 needs to be disassembled and the above operation can be reversed. When using the slot cutter, the mounting handle 1 (the mounting handle 1 adopts a standardized interface design and can be adapted to a variety of processing tool holders) is installed on the tool holder of the machine tool. When it is necessary to replace the blade 8 (the blade 8 adopts a standard universal circular milling blade), the fixing screw 7 is screwed out of the blade 8 to replace the blade 8.
