DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 4 As shown, a superhard tool for high-performance cutting of high-strength steel comprises a tool body 1 and a blade 3. A tool groove 2 is provided on the top surface of the tool body 1, and the blade 3 is arranged inside the tool groove 2. A pressing strip 4 is provided on the top surface of the tool body 1. Both the tool body 1 and the blade 3 are made of high-strength steel, thereby improving the hardness of the tool body 1 and the blade 3, improving the performance of the blade 3, and improving the cutting effect. A sliding groove 5 is provided on the top surface of the tool body 1, and a sliding block 6 is slidably connected inside the sliding groove 5. The sliding block 6 is connected to the pressing strip 4, and a limiting rod 7 is connected inside the sliding groove 5. The limiting rod 7 is slidably connected to the inside of the sliding block 6. A spring 8 is connected to one side of the sliding block 6, and the other end of the spring 8 is connected to one side of the inside of the sliding groove 5. A threaded hole 9 is provided on the top surface of the blade 3 and the inner bottom surface of the tool groove 2. A threaded rod 10 is threadedly connected to the inner thread of the threaded hole 9, and a groove is provided on the top surface of the threaded rod 10, and a rotating strip 18 is provided in the groove.

[0021] During use, the staff can push the set pressing bar 4 through the set pressing bar 4, at this time the pressing bar 4 drives the sliding block 6 to slide inside the sliding groove 5, and the sliding block 6 will squeeze the spring 8 when moving, and then the staff can put the blade 3 into the inside of the knife groove 2, at this time, turn the set rotating bar 18, and then let the rotating bar 18 rotate the threaded rod 10 to enter the inside of the threaded hole 9, to achieve the assembly of the knife body 1 and the blade 3, at this time the staff releases the pressing bar 4, the potential energy of the spring 8 is released to drive the sliding block 6 to reset, and then let the pressing bar 4 press the blade 3 to limit the position, so that the blade 3 is more stable during use, and the assembly effect of the knife body 1, the blade 3 and the pressing bar 4 is achieved, no tools are required throughout the process, and the assembly is more convenient. If the blade 3 is disassembled later, the reverse operation can be performed.

[0022] like Figure 3-Figure 4 As shown, moving grooves 11 are respectively provided on both sides of the interior of the sliding groove 5, and a moving block 12 is slidably connected inside the moving groove 11, and the moving block 12 is connected to the sliding block 6. A stopper 13 is connected to the top surface of the blade body 1, and a connecting rod 14 is connected to one side of the stopper 13. A connecting groove 15 is provided on one side of the pressing strip 4, and the connecting rod 14 is movably connected to the connecting groove 15. A fixed groove 16 is provided on the top surface of the blade body 1, and a magnetic strip 17 is fixedly sleeved inside the fixed groove 16.

[0023] During use, by setting the moving block 12, when the sliding block 6 slides inside the sliding groove 5, the moving block 12 will slide inside the moving groove 11, which on the one hand improves the sliding stability of the sliding block 6, and on the other hand prevents the sliding block 6 from escaping from the sliding groove 5.

[0024] When the tool 3 is in the working state, the operator can push the pressing bar 4, and the pressing bar 4 drives the sliding block 6 to slide inside the sliding groove 5, and the sliding block 6 will squeeze the spring 8 when it moves. Then the operator can put the blade 3 into the inside of the knife groove 2, and then turn the rotating bar 18, so that the rotating bar 18 rotates the threaded rod 10 to enter the inside of the threaded hole 9, so as to assemble the knife body 1 and the blade 3. At this time, the operator releases the pressing bar 4, and the potential energy of the spring 8 is released to drive the sliding block 6 to reset, so that the pressing bar 4 presses and limits the blade 3, so that the blade 3 is more stable during use, and the assembly effect of the knife body 1, the blade 3 and the pressing bar 4 is achieved. No tools are required in the whole process, and the assembly is more convenient. If the blade 3 is disassembled later, the reverse operation can be performed.

[0025] By setting the pressing strip 4, when the pressing strip 4 is reset, the pressing strip 4 and the magnetic strip 17 will be magnetically attracted together, and at the same time, the pressing strip 4 will fit with the block 13 and the connecting rod 14 will enter the inside of the connecting groove 15, so as to achieve the effect of assembling the connecting rod 14 and the pressing strip 4. The stability of the pressing strip 4 during use is further improved by magnetic attraction and plug-in.
