[0027] like Figure 2 As shown, in a preferred embodiment of the present invention, the tool body 10 includes a slide groove 12, which extends in an arc shape with the pivot point 11 as the center of the circle. The adjustment component 30 is inserted into the slide groove 12 and can move along the slide groove 12 and rotate with the pivot point 11 of the tool body 10 as the axis, driving the blade 20 to pivot relative to the tool body 10. In other embodiments, the adjustment component 30 can also be connected to the blade 20, so as to adjust the inclination angle θ and then fix it to the tool body 10 with other connecting parts such as bolts. Similarly, the adjustment component 30 can rotate with the pivot point 11 of the tool body 10 as the axis to drive the blade 20 to pivot relative to the tool body 10, and can make the blade 20 relatively fixed to the tool body 10.

[0028] like Figure 2 As shown, in a preferred embodiment of the present invention, the adjustment component 30 includes a blade seat 31, a clamping member 32 and a pressing member 33, wherein the blade 20 can be driven by the adjustment component 30 to pivot relative to the tool body 10, or be restricted by the adjustment component 30 and fixed relatively to the tool body 10, the clamping member 32 is provided on the blade seat 31, and the pressing member 33 can be driven to press against the clamping member 32, so that the clamping member 32 and the blade seat 31 jointly clamp the tool body 10 and are relatively fixed to the tool body 10, and the blade 20 is restricted by the blade seat 31 and is relatively fixed to the tool body 10.

[0029] like Figure 2As shown, specifically, the blade seat 31 includes a track inserting portion 311 and two clamping portions 312. The blade seat 31 is inserted into the slide groove 12 of the tool body 10 with the track inserting portion 311, so that the blade seat 31 can move along the slide groove 12 and rotate with the pivot point 11 of the tool body 10 as the axis. The two clamping portions 312 and the track inserting portion 311 are respectively located at opposite ends of the blade seat 31. The two clamping portions 312 are arranged opposite to each other. The blade 20 includes three blade edges, which are interconnected to form an equilateral triangle structure, one of the blade edges serving as the processing edge 21, and the other two blade edges serving as two clamping edges 22, as shown in FIG. Figure 3 As shown, the two clamping portions 312 respectively abut against the two clamping edges 22 of the blade 20, so that the blade 20 can be Figure 6 As shown, the adjusting assembly 30 is driven to pivot relative to the tool body 10 , or can be restricted by the adjusting assembly 30 and fixed relative to the tool body 10 when the adjusting assembly 30 and the tool body 10 are relatively fixed.

[0030] In a preferred embodiment of the present invention, the blade 20 includes three blade edges connected to form an equilateral triangle structure. In actual use, one of the blade edges is used as the processing edge 21, and the other two blade edges are used as the two clamping edges 22 respectively. In other embodiments, as long as the blade 20 includes the processing edge 21 protruding from the tool body 10, the blade 20 can also have structures of other shapes. The advantage of the preferred embodiment of the present invention is that after one of the blade edges serving as the processing edge 21 is worn out after a period of processing, the blade 20 can be reinstalled and the other blade edge originally serving as the clamping edge 22 can be used as the new processing edge 21, so as to fully utilize the blade 20.

[0031] In addition, in a preferred embodiment of the present invention, the two clamping portions 312 clamp the two clamping edges 22 of the blade 20 having a triangular structure, so that the blade 20 can be driven by the adjusting component 30 to pivot relative to the tool body 10, or can be restricted by the adjusting component 30 and fixed relatively to the tool body 10. In other embodiments, the blade 20 and the adjusting component 30 can also be fixedly combined using a screw lock structure, a tenon structure or other methods, which can also achieve the effect of enabling the blade 20 to be driven by the adjusting component 30 or restricted by the adjusting component 30. The advantage of the preferred embodiment of the present invention is that the blade 20 and the adjusting component 30 are easy to separate, and when the blade 20 or the adjusting component 30 is damaged, the disassembly and maintenance operations are more convenient.

[0032] like Figure 2As shown, in a preferred embodiment of the present invention, the tool body 10 further includes an auxiliary groove 13 and a positioning protrusion 14, the auxiliary groove 13 and the slide 12 are spaced apart and extend in the same direction, the positioning protrusion 14 is formed between the auxiliary groove 13 and the slide 12, the blade seat 31 further includes an insertion hole 313, the insertion hole 313 is arranged along the direction from the track insertion portion 311 toward the two clamping portions 312, as shown in FIG. Figure 4 As shown, the clamp 32 is inserted into the insertion hole 313 and inserted into the auxiliary groove 13, so that the clamp 32 can move along the auxiliary groove 13 and rotate together with the blade seat 31 around the pivot point 11 of the tool body 10. The pressing member 33 is a set screw, and the blade seat 31 is also provided with a screw hole, which extends from the top of the blade seat 31 to the insertion hole 313.

[0033] like Figure 4 As shown, when the pressing member 33 is screwed into the screw hole and is continuously rotated to press downward against the clamping member 32, the clamping member 32 and the track insert 311 of the blade seat 31 jointly clamp the positioning protrusion 14 of the tool body 10, so that the clamping member 32 and the blade seat 31 and the tool body 10 are relatively fixed, and the blade 20 is also restricted by the blade seat 31 and fixed relative to the tool body 10. When the pressing member 33 is rotated in the opposite direction and moves upward, the clamping member 32 and the blade seat 31 no longer clamp the positioning protrusion 14, so that the blade seat 31 can rotate again with the pivot point 11 of the tool body 10 as the axis and drive the blade 20 to pivot relative to the tool body 10.

[0034] As described in the above paragraph, in the preferred embodiment of the present invention, the adjusting assembly 30 is equipped with the clamping member 32 and the pressing member 33 in conjunction with the blade holder 31. By means of clamping, after adjusting the inclination angle θ of the processing edge 21 of the blade 20, the adjusting assembly 30 can be fixed relative to the tool body 10 to restrict the blade 20, so that the blade 20 is also fixed relative to the tool body 10 and no longer pivots, and the inclination angle θ is kept unchanged after the adjustment. In other embodiments, the tool body 10 can also be provided with A plurality of fixing screw holes are arranged in an arc shape with the pivot point 11 of the tool body 10 as the center. After adjusting the tilt angle θ, a bolt is passed through the adjustment assembly 30 and screwed into one of the fixing screw holes. This can also achieve the effect of maintaining the tilt angle θ after adjustment. The advantage of the preferred embodiment of the present invention is that, by using a clamping method, the range of adjustment of the tilt angle θ is not limited to a few fixed angles as in the above-mentioned method of using the fixing screw holes and bolts, but can be adjusted at will. Specifically, Figure 6 The tilt angle θ shown can be adjusted between 0° and 90°.

[0035] like Figure 2 As shown, in a preferred embodiment of the present invention, the tool body 10 further includes a plurality of angle indicating units 15, which are provided on a top surface of the tool body 10 and are arranged in an arc shape along the auxiliary groove 13, that is, with the pivot point 11 of the tool body 10 as the center of the circle, and the plurality of angle indicating units 15 are arranged at equal intervals. The adjustment component 30 further includes an alignment unit 34, which can be aligned with one of the angle indicating units 15 as the adjustment component 30 rotates with the pivot point 11 of the tool body 10 as the axis. Whereby, when the adjustment component 30 rotates to adjust the inclination angle θ between the processing edge 21 of the blade 20 and the axial direction of the tool body 10, the size of the currently adjusted inclination angle θ can be indicated, thereby increasing convenience in use.

[0036] In a preferred embodiment of the present invention, the above-mentioned several angle indicating units 15 are specifically several grooves engraved on the top surface of the tool body 10, and the alignment unit 34 is specifically a groove engraved on the top of the blade seat 31. In other embodiments, the several grooves can also be several protrusions, several strips, and can also be provided on the positioning protrusion, or other positions for the user to observe. The alignment unit 34 can also be a protrusion, a strip, a pointer or other forms that can align with the angle indicating unit 15. It is even possible not to provide the alignment unit 34, and directly use one of the blade edges of the blade 20 as the reference for aligning the angle indicating unit 15. As long as the tool body 10 is provided with several angle indicating units 15, it can indicate the size of the inclination angle θ of the processing edge 21 of the blade 20 when the adjustment component 30 rotates, and its form is not limited to the preferred embodiment of the present invention.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical solution proposed by the present invention, make partial changes or modifications to the technical content disclosed in the present invention and make equivalent embodiments without departing from the technical solution content of the present invention. All of these remain within the scope of the technical solution of the present invention.
