The cutter 4 is arranged at the end part of the motor shaft 3, an external thread section 5 is arranged on the motor shaft 3, the external thread section 5 is in threaded connection with an adjusting threaded sleeve 6 with adjustable height, the cutter 4 comprises a cylindrical cutter body 41, one end of the motor shaft 3 is sleeved with the cutter body 41 and is abutted against the adjusting threaded sleeve 6, and a fixing component which is matched with the adjusting threaded sleeve 6 to fix the cutter body 41 on the motor shaft 3 is further arranged in the cutter body 41. The adjusting screw sleeve 6 can position the installation position of the cutter 4, and the positioning height of the cutter 4 can be changed by adjusting the position of the adjusting screw sleeve 6.

Specifically, as shown in fig. 2 and 3, the cutter 4 in this embodiment is a milling cutter, and includes a cylindrical cutter body 41, a plurality of blades 42 are disposed on an outer wall of the cutter body 41 at intervals, a shoulder 411 is disposed on an inner wall of the cutter body 41 in an annular shape along an inner wall of the cutter body 41, a front-rear through receding hole 412 is disposed in a middle portion of the shoulder 411, the fixing component includes a retaining ring 7 and a fixing bolt 8, the retaining ring 7 is disposed on a side of the shoulder 411 away from the adjusting screw sleeve 6 and abuts against the shoulder 411, a threaded hole 31 is disposed on an end surface of a connecting end of the motor shaft 3 and the cutter body 41, the threaded hole 31 is disposed along an axial direction of the motor shaft 3, after the cutter body 41 is fitted on the motor shaft 3, an end portion of the motor shaft 3 extends into the receding hole 412 and. Of course, in the actual use process, the cutter 4 may also be a disc cutter, a saw or other cutters.

Therefore, when the height of the cutter 4 is too low, the cutter 4 can be adjusted by moving the adjusting threaded sleeve 6 upwards to a certain position and then screwing the fixing bolt 8 to enable the cutter 4 to move upwards and abut against the adjusting threaded sleeve 6. When the height of the cutter 4 is too high, the fixing bolt 8 can be firstly screwed to enable the cutter 4 to move downwards, and the adjusting threaded sleeve 6 moves downwards to abut against the cutter 4 after the cutter 4 moves in place, so that the adjustment and the fixation of the cutter 4 are completed.

Of course, the fixing assembly can also directly adopt bolts to replace the structure of the retaining ring 7 for reinforcing the fixing bolts 8.

Further, as shown in fig. 3 to 5, the end of the motor shaft 3 is provided with the insertion part 32, the insertion part 32 is of a non-circular structure, the end face of the retainer ring 7 facing the motor shaft 3 is provided with an insertion groove 71, the shape of the insertion groove 71 is matched with that of the insertion part 32, and the insertion part 32 extends into the insertion groove 71 to enable the retainer ring 7 to be circumferentially fixed relative to the motor shaft 3, so that the retainer ring 7 can synchronously rotate when the motor shaft 3 rotates, looseness of a fixed structure is avoided, and stability of cutter fixing is ensured. In this embodiment, the insertion part 32 has a kidney-shaped structure formed by cutting chips on both sides of the end of the motor shaft 3, and the insertion groove 71 is also a kidney-shaped groove. Of course, in actual use, the insertion part 32 may also adopt other non-circular structures with a triangular or polygonal cross section.

Example two

As shown in fig. 6 to 8, the present embodiment is substantially the same as the first embodiment, except that another structure is adopted to adjust the height of the tool, in the present embodiment, a clamping mechanism 9 is provided at one end of a motor shaft 3 of a motor 2, and the clamping mechanism 9 can clamp and fix the tool 4 after the tool 4 is inserted therein. In this embodiment, the tool 4 includes a tool body section 4b, an external thread section 5 and a fixing section 4a, the tool body section 4b, the external thread section 5 and the fixing section 4a are sequentially distributed along an axial direction of the tool 4, wherein the fixing section 4a is embedded in the clamping mechanism 9, the external thread section 5 is in threaded connection with the adjusting screw sleeve 6, and the adjusting screw sleeve 6 abuts against an outer end face of the clamping mechanism 9. The blade section 4b of the tool 4 may be directly machined to form a blade, or the blade may be fixedly disposed by using a split structure, in this embodiment, the tool 4 is a drill, and the tool 4 may also be another tool such as a milling cutter, a disc cutter, or a saw.

Further, in the present embodiment, the clamping mechanism 9 includes a clamping jaw 91 and a lock nut 92, and the lock nut 92 is in threaded engagement with the clamping jaw 91 and can adjust tightness of the clamping jaw 91.

Further, in order to facilitate the installation of the adjustment screw 6, the external thread section 5 has an outer diameter larger than that of the fixing section 4a, so that the adjustment screw 6 can be installed from the fixing section 4a of the tool 4.

When the cutter 4 is installed, the position of the adjusting threaded sleeve 6 can be adjusted in place in advance, then the fixing section 4a is inserted into the clamping mechanism 9, the adjusting threaded sleeve 6 is abutted against the outer end face of the clamping mechanism 9, and then the clamping mechanism 9 clamps and fixes the adjusting threaded sleeve 6. When the position of the cutter 4 is too high, only the clamping mechanism 9 needs to loosen the fixed section 4a firstly, so that the clamping mechanism 9 can clamp the fixed section 4a, and the fixed section 4a can move axially relative to the clamping mechanism 9 under the action of external force, at the moment, the cutter 4 moves downwards relative to the clamping mechanism 9 by screwing the adjusting screw sleeve 6, and the fixed section 4a is clamped again after the cutter moves in place. When the height of the cutter 4 is too low, the positions of the cutter 4 and the adjusting screw sleeve 6 are adjusted firstly, so that the height of the cutter 4 is slightly higher than the target height, and then the cutter 4 moves downwards and reaches the target height by screwing the adjusting screw sleeve 6 according to the previous steps.
