[0025] Embodiment 1: A high strength PCD tool, such as Figure 1-Figure 4As shown, it includes a knife body 1 and two rotating bolts 2 threadedly arranged inside the knife body 1, the rotating bolt 2 extends out of one side of the knife body 1, and the end of the rotating bolt 2 away from the knife body 1 is fixedly connected to the support bolt 3, and a blade 6 is fixedly connected to the outside of the support bolt 3, and the blade 6 is plugged with a fixed support cylinder 4, and the fixed support cylinder 4 is threadedly connected to the support bolt 3, and a plurality of plug-in rods 11 are plugged inside the fixed support cylinder 4, and a fastening support block 10 is fixedly connected to one side of the plug-in rod 11, and a fastening plate 7 is slidably arranged at the lower end of the fastening support block 10. When the device is running, the two rotating bolts 2 inside it are rotated under the support of the knife body 1, so that the support bolt 3 on one side is rotated at the same time under the threaded support of the knife body 1 and the fixed support cylinder 4, so that the blade 6 follows the rotation of the support bolt 3 to achieve the purpose of tightening it. The effect of adjusting the angle of the blade 6 is achieved. At the same time, by setting the connection between the blade 6 and the fixed support tube 4 to a specification larger than the length of the blade 6 itself, it is ensured that the device can support the short-distance movement of the blade 6 when adjusting the angle, thereby improving the stability of the blade 6 when adjusting the angle, and by the connection support of the fastening plate 7 by multiple fastening support blocks 10, the stability of the device blade 6 after position adjustment is further improved, and by the threaded support of the rotating bolt 2 and the support bolt 3 by the cutter body 1 and the fixed support tube 4, it is ensured that after the rotating bolt 2 and the support bolt 3 are limited, their stability inside the device is improved, thereby improving the stability of the device when in use, so that the angle adjustment effect can be achieved when the device is in use, which is convenient for the device to perform different cutting uses.

[0026] like Figure 1-Figure 4 As shown, a positioning groove 18 is provided at one end of the rotating bolt 2, and the positioning groove 18 is inserted with a limiting column 13 and a limiting nut 14. The limiting column 13 and the limiting nut 14 are both located inside the knife body 1, and the limiting column 13 is inserted with a clamping block 15, and the clamping block 15 is clamped and connected with the knife body 1. The limiting column 13 extends to one end of the clamping block 15, and the limiting column 13 is fixedly connected with a connecting plate 16, and the connecting plate 16 is fixedly connected with two limiting columns 13 at the same time. By simultaneously supporting the two clamping blocks 15 on the connecting plate 16 and connecting the limiting column 13 inside it to the limiting nut 14, the positioning grooves 18 on one side of the knife body 1 and the rotating bolt 2 are simultaneously clamped and limited. By simultaneously connecting the connecting plate 16 to the positioning grooves 18 on both sides, the two rotating bolts 2 can be protected and limited at the same time, and the corresponding clamping placement of the limiting nut 14 in the positioning groove 18 can further stabilize the rotating bolt 2 when it is limited.
