[0026] Working principle:

[0027] First, the user fixes the tool handle clamping block 1 on the machine tool or other processing equipment. When it is necessary to adjust the length of the milling cutter to adapt to the processing of workpieces of different sizes, the user can adjust the tool handle limit block 3 to achieve the adjustment of the tool size. The first tool rod 5 is inserted into the tool rod mounting groove 18 opened in the telescopic tool handle 2, and then the tool handle limit block 3 is installed in the limit block mounting groove 14 of the telescopic tool handle 2. The limit bolt 4 is twisted to make the limit bolt 4 screwed into the bolt mounting hole 16. During the twisting process, the front end of the limit bolt 4 pushes against the first limit block 15, which will push the first limit block 15 to both sides. At the same time, the outer wall of the first limit block 15 and the inner side of the tool rod adjustment groove 10 are butted against each other, which can improve the stability of the tool and ensure the stability during the processing. In addition, when adjusting the tool, it is only necessary to loosen the limit bolt 4 and pull out the first tool rod 5. The telescopic length of the tool can be intuitively understood by observing the adjustment scale 11, so as to make precise adjustments. When it is adjusted to the appropriate length, the user can The limit bolt 4 is tightened to fix the tool handle limit block 3, thereby ensuring that the telescopic length of the telescopic tool handle 2 and the first tool rod 5 will not change during use. In addition, a tool rod adjustment groove 10 is opened on the outer periphery of the first tool rod 5, which is slidably connected to the auxiliary mounting strip 17 inside the telescopic tool handle 2, so that the first tool rod 5 can perform telescopic movement inside the telescopic tool handle 2. Secondly, the tool block mounting groove 7 opened on the outer periphery of the first cutter head 6 is used to install the milling tool block 8. The milling tool block 8 is fixedly connected to the first cutter head 6 through the tool block fixing hole 12 and the tool block limit hole 13, and is fastened by the tool block fixing screw 9 so that the milling tool block 8 can be easily replaced and repaired, reducing the maintenance cost of the user. Then, during the working process, the machine tool drives the tool handle clamping block 1 and the entire milling cutter to rotate, and the first cutter head 6 and the milling tool block 8 thereon perform milling processing on the workpiece. Since the telescopic adjustable T-type milling cutter has a telescopic adjustment function, it can adapt to the processing needs of workpieces of different sizes without the need for frequent tool replacement, thereby improving work efficiency.
