Embodiment 1

[0021] As Figures 1 to 4 shown, a tungsten steel end mill with an anti-flying structure includes a clamping handle 1, and one end of the clamping handle 1 is connected with an adjusting mechanism for adjusting the milling cutter;

[0022] The adjusting mechanism includes an adjusting rod 2, the adjusting rod 2 is arranged inside the clamping handle 1, two limiting grooves 21 are opened on the outer surface of the adjusting rod 2, and limiting strips 22 fixedly connected with the inner wall of the clamping handle 1 are slidably connected inside the two limiting grooves 21. A plurality of fixing holes 23 are equidistantly opened on the outer surface of the adjusting rod 2. A fixing bolt 3 is installed on the outer surface of the clamping handle 1, and the end of the fixing bolt 3 is inserted and connected with the fixing hole 23. An anti-slip sleeve 4 is fixed on the outer wall of the clamping handle 1. One end of the adjusting rod 2 is connected with a milling cutter body 5. Through the anti-slip sleeve 4 arranged on the clamping handle 1, the anti-slip effect can be achieved.
