[0024] In the specific implementation process, it is worth pointing out that the cooperation between the cutter head 12, the positioning column 13 and the baffle 18 realizes the rapid fixation of the cutter head 12 and facilitates the finding of the fixed position, thus solving the problem that the existing cutter holder is not convenient for the user to install the cutter head 12, prolongs the time in actual operation and reduces the work efficiency;

[0025] Furthermore, a round rod 19 is fixedly connected to the bottom of the baffle 18, and the outer side of the round rod 19 is movably connected to the block 14. The round rod 19 can move in the through hole of the block 14. The back of the block 14 is fixedly connected to the outer side of the bottom plate 7. The outer side of the round rod 19 is movably connected to a spring 20, and the two ends of the spring 20 are respectively fixedly connected to the bottom of the baffle 18 and the top of the block 14;

[0026] In the specific implementation process, it is worth pointing out that the device can drive the baffle 18 to always fit the front of the cutter head 12 for limiting by relying on the elastic deformation of the spring 20;

[0027] Furthermore, the upper part of the frame body 1 is threadedly connected with a screw 4, and the lower part of the outer wall of the screw 4 is threadedly connected with the upper threaded hole of the machine tool slide rail 2;
