Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention: a precision tool for a suction head, including a tool shank 1, a tool bit 8 and a milling blade 10. A connecting platform 2 is fixed at the bottom end of the tool shank 1. A telescopic tool rod assembly is arranged at the bottom end of the connecting platform 2. The tool rod assembly includes a guide rod 3, a sliding tube 4, an adjusting hole 5, an adjusting bolt 6 and a scale groove 7. A guide rod 3 is fixed at the bottom end of the connecting platform 2. A sliding tube 4 is arranged on the outer side of the guide rod 3. An adjusting hole 5 is arranged on one side of the sliding tube 4. A plurality of adjusting holes 5 are arranged on one side of the sliding tube 4. The plurality of adjusting holes 5 are distributed in parallel. An adjusting bolt 6 is arranged inside the adjusting hole 5. Internal threads are arranged inside the adjusting hole 5. External threads are arranged on the surface of the adjusting bolt 6. One side of the adjusting bolt 6 extends into the inside of the sliding tube 4. A scale groove 7 is arranged on the other side of the guide rod 3. A plurality of scale grooves 7 are arranged on the other side of the guide rod 3. The plurality of scale grooves 7 are distributed at equal intervals;

[0024] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, during use, multiple groups of adjusting holes 5 are arranged at the side end of the sliding tube 4. After loosening the adjusting bolt 6 inside the adjusting hole 5, the sliding tube 4 can slide up and down along the guide rod 3. By means of the movement of the sliding tube 4, the position of the tool bit 8 below can be adjusted. Also, the sliding tube 4 can be slid down along the guide rod 3. After separating the sliding tube 4 from the guide rod 3 and removing it, the sliding tube 4 and the tool bit 8 below can be replaced or maintained;

[0025] The bottom end of the sliding tube 4 is fixed with a cutter head 8. Knife grooves 9 are arranged at both ends of the outer side wall of the cutter head 8. Milling cutter blades 10 are arranged inside the knife grooves 9. An installation bolt 11 is arranged on one side of the milling cutter blade 10. A protective sleeve 12 is arranged outside the cutter head 8. A lining pad 13 is fixed at the bottom end inside the tool handle 1. Auxiliary grooves 14 are arranged on the inner side wall of the protective sleeve 12. There are four groups of auxiliary grooves 14 arranged on the inner side wall of the protective sleeve 12, and the four groups of auxiliary grooves 14 are symmetrically distributed;

[0026] Specifically, as Figure 1 and Figure 2 shown, during use, the protective sleeve 12 is sleeved outside the cutter head 8 to wrap the cutter head 8. The multiple groups of auxiliary grooves 14 on the inner side of the protective sleeve 12 can be used for the milling cutter blades 10 outside the cutter head 8 to be inserted, which can prevent the inner side wall of the protective sleeve 12 from being damaged when the cutter head 8 is inserted into the inner side of the protective sleeve 12 due to the milling cutter blades 10 being installed in the knife grooves 9 on the surface of the cutter head 8;

[0027] An installation hole 15 is arranged inside the guide rod 3. A plug rod 16 is arranged inside the installation hole 15. A drill rod 17 is fixed at the bottom end of the plug rod 16. A fixing hole 18 is arranged at the bottom end on one side of the guide rod 3. A fixing bolt 19 is arranged inside the fixing hole 18, and one side of the fixing bolt 19 extends to the inside of the installation hole 15;

[0028] Specifically, as Figure 1 and Figure 4 shown, during use, the plug rod 16 at the top of the drill rod 17 is inserted into the installation hole 15 inside the guide rod 3, and multiple groups of fixing bolts 19 on the side end are tightened to fix the plug rod 16, completing the installation operation of the drill rod 17. The drill rod 17 is located at an internal position. If the outer sliding tube 4 is removed, the drill rod 17 at the internal position can also be used for processing operations to process small holes.

[0029] Working principle: During use, the milling blade 10 is installed in the tool groove 9 on the outer wall of the tool head 8 and fixed by the mounting bolt 11. The tool handle 1 is inserted into the tool holder for use. If the hole is relatively deep, the adjusting bolt 6 inside the adjusting hole 5 at the side end of the sliding tube 4 can be loosened. At this time, the sliding tube 4 can move downward along the guide rod 3, and the scale groove 7 exposed on the other side can assist the operator in judging the downward movement distance. By means of the downward movement of the sliding tube 4, the tool head 8 below can be driven to move downward, increasing the overall use length. After adjustment, the adjusting bolt 6 is tightened again to fix the position of the sliding tube 4. At the same time, the insertion rod 16 at the top of the drill rod 17 is inserted into the mounting hole 15 inside the guide rod 3, and the fixing bolt 19 at the side end is tightened for fixation. The whole is located inside. If the adjusting bolt 6 at the side end of the sliding tube 4 is loosened and the sliding tube 4 is moved downward, after driving the sliding tube 4 to separate from the guide rod 3, the drill rod 17 at the inner side is exposed. The diameter of the drill rod 17 is relatively small, and the processing operation of a smaller hole can be carried out. After the tool is used, the protective sleeve 12 can be sleeved on the outside of the tool head 8. With the help of the protective sleeve 12, it can prevent the tool head 8 and the milling blade 10 from contacting foreign objects and being damaged, and provide auxiliary protection for them.
