It can be understood that the cutter bar 2 will form a spiral motion after being axially moved when being radially pressed by the pressing mechanism 32, and the spiral stroke angle is related to the contact pressing direction of the pressing mechanism 32, so that the turning mechanism 4 is required to drive the pressing mechanism 32 to rotate for adjusting correspondingly in order to match different spiral angles of the cutting groove on the cutter 81.

More specifically, the turning mechanism 4 includes an adjusting opening 41 and an insert 42, the insert 42 is inserted into the pressing mechanism 32 through the adjusting opening 41 and protrudes from the adjusting opening 41, the insert 42 can slide along the adjusting opening 41, and therefore, a user can rotate the pressing mechanism 32 by turning the insert 42.

More specifically, the base 31 is cylindrical, the adjustment opening 41 is disposed through the base 31 in a radial direction, the steering mechanism 4 further includes a ring 43 and a shifting member 44, the ring 43 is rotatably sleeved on the base 31, the ring 43 is recessed with a receiving groove 431, the receiving groove 431 is used for receiving the portion of the plug 42 protruding from the adjustment opening 41, the ring 43, the plug 42 and the pressing mechanism 32 are in the same rotating relationship, and the shifting member 44 is inserted in the ring 43 for external operation to drive the ring 43 to rotate. Wherein, the ring sleeve 43 covers the adjusting opening 41 to effectively stop the foreign object from entering the base 31 through the adjusting opening 41, in other words, the ring sleeve 43 can keep the operating environment of the pressing mechanism 32 in a better state; moreover, the ring 43 is heavy and can withstand unexpected external force, thereby preventing the occurrence of accidental rotation.

Preferably, the shifting member 44 is disposed through the ring 43 and can be positioned to move along the passing direction, so that the shifting member 44 can selectively abut against the base 31 to position the ring 43. Therefore, when the pressing mechanism 32 is rotated to a desired angle, the user can screw the pulling element 44 tightly against the base 31 to achieve the angular positioning.

Therefore, the blocking unit 327 can precisely control the maximum force of the pressing wheel seat 321 against the tool feeding bar 2 to be a predetermined pressure value, so that the tool feeding bar 2 can be kept smooth and without slipping during the spiral movement, thereby ensuring better grinding quality. In addition, in the direction perpendicular to the tool feeding bar 2, the farthest distance from the adjusting opening 41 closer to the opening wall of the tool feeding bar 2 to the insert 42 is equal to the predetermined distance, and the double limit guarantee can be achieved by cooperating with the stop unit.

It should be noted that, in the first embodiment, the adjusting member 323 and the base 31 are matched, so that the adjusting member 323 can provide a force to the pressing wheel seat 321, and the pressing wheel seat 321 can reliably press against the tool feeding bar 2.

However, the pressing mechanism 32 is not limited to the above-mentioned aspect, and can also be as shown in the second embodiment of fig. 14 and 15: the pressing mechanism 32A further includes a pressure unit 325, and the adjusting member 323A can penetrate through the base 31A along the direction transverse to the tool feeding bar 2 in a relatively idle manner, and then the adjusting member 323A is fixed to the pressing wheel seat 321A in a synchronous relationship, wherein the pressure unit 325 is located between the pressing wheel seat 321A and the base 31A, and in the extending direction of the adjusting member 323A, the pressure unit 325 normally provides an acting force to the pressing wheel seat 321A, and further drives the pressing wheel seat 321A to press the tool feeding bar 2. In short, in the second embodiment, the pressing unit 325 cooperates with the base 31A to provide a force to the pressing wheel seat 321A, and the weight of the pressing wheel seat 321A itself presses the tool feeding bar 22.

It should be noted that, in the first embodiment, the stopping unit 327 is composed of two nuts, and the adjusting member 323 is movably screwed to the stopping unit 327, wherein the stopping unit 327 functions as a stop limit in the first embodiment, while the stopping unit 327 is configured in the same manner in the second embodiment, but additionally has another special important function.

In more detail, in the second embodiment, a user can rotate the adjusting element 323A based on the blocking unit 327 abutting against the base 31A to lift the adjusting element 323A relative to the blocking unit 327, and then lift the pressing wheel seat 321A, so that the pressing wheel seat 321A does not abut against the tool feeding rod 2, and the tool feeding rod 2 can rotate freely to perform other operations. More specifically, the pressure unit 325 is a warped plate, the pressing mechanism 32A further includes at least one pressing member 326, the at least one pressing member 326 is movably disposed on the base 31A along the extending direction of the adjusting member 323A, and the at least one pressing member 326 selectively presses the pressure unit 325 to increase the force of the pressure unit 325 against the pressing wheel seat 321A.

Moreover, the openings of the plurality of second positioning portions 52 preferably face the operating end 22, and the first positioning portion 51 extends toward the working end 21, so that, in practical operation, when the working end 21 is far away from the grinding wheel 82 and retracts to abut against the seat body 1 after the first knife slot is ground, the first positioning portion 51 can be inserted into the second positioning portion 52 corresponding to the ground first knife slot, thereby achieving the purpose of automatically positioning the knife feeding bar 2 (see fig. 6 to 7).

Then, the pressing wheel seat 321 is lifted, the tool feeding bar 2 is pushed to advance to separate the second positioning portion 52 from the first positioning portion 51, and then the tool feeding bar 2 is rotated according to the angle (e.g. 30 degrees) between the two grooves to make the second positioning portion 52 representing the next groove correspond to the first positioning portion 51 (as shown in fig. 8), and after the adjustment, the tool feeding bar 2 is retracted to make the first positioning portion 51 insert and position the second positioning portion 52 represented by the second groove, and at this time, the pressing wheel seat 321 is controlled to press and press the tool feeding bar 2, so that the adjustment of the second groove is completed, and the user can perform the grinding operation of the second groove.

From the above, it can be fully understood that the grinding process from the first cutting edge to the second cutting edge is very precise and accurate, so that the ground cutter 81 has excellent grinding quality, and the other cutting edge switching steps can repeat the above operations; in addition, the whole operation on the positioning actuation is very consistent with the actual operation flow, and a user is very easy to get on hand.
