An adjusting block 11 is slidably connected to the inner wall of the activity groove 12. A limiting block 13 is slidably connected to the inner wall of the limiting groove 14. A first fastening bolt 6 is provided in the middle of the limiting block 13. Docking holes 10 are opened on the outer walls of the body 1 and the adjusting block 11. A connecting rod 3 is inserted into the inner wall of the docking hole 10. A positioning hole 9 is opened at one end of the connecting rod 3 away from the adjusting block 11. A second fastening bolt 7 is threadedly connected to the inner wall of the positioning hole 9. A positioning screw 4 is fixedly assembled on the outer wall of the adjusting block 11. A nut 5 is threadedly connected to the outer wall of the positioning screw 4. Through grooves 8 are opened on the outer walls of both sides of the body 1.

[0021] In the above structure, through the structures of the body 1, the sliding groove 2, the connecting rod 3, and the second fastening bolt 7, when the reamer needs to be maintained and replaced during use, the user can fix the reamer in the turning groove through the second fastening bolt 7, without grinding the reamer and without performing the operation of bending the tool, saving 15 minutes of tool grinding time, thus solving the problem of no suitable tool for machining the O-ring airtight groove of the airtight positioning disc, and further improving the operation efficiency of the user.

[0022] In a preferred implementation mode: the inner wall of the sliding groove 2 is slidably connected to the outer wall of the first fastening bolt 6. Threaded holes are opened on the outer walls of the limiting block 13 and the connecting rod 3, and the inner walls of the threaded holes are threadedly connected to the outer wall of the first fastening bolt 6. The connecting rod 3 is fixedly connected to the adjusting block 11 through the first fastening bolt 6, and the adjusting block 11 is fixedly connected to the body 1 through the positioning screw 4 and the nut 5 respectively.

[0023] In the above structure, through the threaded hole and the fastening bolt 6 structure, the user can insert the connecting rod 3 into the docking hole 10 by turning the fastening bolt 6 and then fix the connecting rod 3, so that the main body 1 and the connecting rod 3 can be quickly connected, and it is also convenient for the user to remove the connecting rod 3 to maintain the main body 1, ensuring that the various accessories of the hollowing knife can be recycled, thereby improving the practicality of the hollowing knife.

[0024] In a preferred embodiment, the outer wall of the positioning screw 4 is slidably connected to the inner wall of the through slot 8 , and the outer wall of the nut 5 is tightly fitted to the outer wall of the body 1 .

[0025] In the above structure, by providing the positioning screw 4 and the through slot 8 structure, when the user adjusts the position of the adjusting block 11, the nut 5 can be loosened to allow the positioning screw 4 to slide along the inner wall of the through slot 8, and the positioning screw 4 is used to limit the adjusting block 11, thereby ensuring the stability of the adjusting block 11 during movement, and also making it convenient for the user to connect the connecting rods 3 of different lengths to the body 1, thereby realizing the effect of recycling the connecting rods 3.

[0026] In a preferred embodiment, the number of the positioning screws 4 and the number of the nuts 5 are both two, and the two positioning screws 4 and the two nuts 5 are symmetrically distributed along the outer wall of the body 1 .

[0027] In the above structure, through the two positioning screws 4 and the nut 5 structure, when the user loosens the nut 5, the position of the adjusting block 11 can be changed by turning the positioning screw 4, so that after the connecting rods 3 of different lengths are connected to the adjusting block 11, the main body 1 can all be connected to the groove, thereby ensuring the normal use of the digging knife, thereby improving the use range of the digging knife and the utilization rate of the material.

[0028] In a preferred embodiment, the outer wall of the fastening bolt 6 is tightly fitted with the outer wall of the main body 1 , and the adjustment block 11 is fixedly connected to the main body 1 via the fastening bolt 6 .

[0029] In the above structure, by setting the fastening bolt 6 and the adjustment block 11 structure, when the user installs the main body 1, he can pick up the connecting rod 3 and insert it into the docking hole 10, and then fix the main body 1 and the connecting rod 3 by rotating the fastening bolt 6, so as to achieve the effect of quickly assembling the digging knife, thereby improving the user's installation efficiency of the digging knife.

[0030] In a preferred embodiment, the body 1 and the connecting rod 3 are both made of white steel bars.

[0031] In the above structure, the white steel bar has excellent properties such as high hot hardness, wear resistance, fast cutting speed, sharp edge trimming, high toughness, and impact resistance. Its bending strength and impact toughness are at the same level as those of ordinary high-speed steel, thus extending the service life of the gouging tool.

[0032] Working principle: First, when the user assembles the gouging tool, the positioning screw rod 4 can be made movable by rotating the nut 5. After loosening the nut 5, the positioning screw rod 4 is toggled to make the adjusting block 11 slide along the inner wall of the movable groove 12, so as to ensure that after the connecting rod 3 is inserted into the docking hole 10, the body 1 and the connecting rod 3 can be fixedly connected to the turning groove. After the adjustment is completed, the user can rotate the nut 5 in the reverse direction to fix the adjusting block 11, then pick up the connecting rod 3 and insert it into the docking hole 10, and fix the body 1 and the connecting rod 3 by rotating the first fastening bolt 6. Finally, the gouging tool can be fixedly assembled with the turning groove by rotating the second fastening bolt 7.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
