Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1-5 As shown, the utility model provides a technical solution: a high-strength hardware cutting tool, comprising a tool holder 1, a fixing structure 2, and a tool head assembly 3, wherein a receiving groove 4 is provided on the tool holder 1, the fixing structure 2 is arranged on the inner side of the receiving groove 4, and the tool head assembly 3 is arranged on a side of the inner side of the receiving groove 4 close to the tool head assembly 3;

[0030] like Figure 2-3 As shown, the fixing structure 2 includes a connecting and fixing block 21 and a connecting rod 22. The connecting and fixing block 21 is arranged on the inner side of the storage groove 4. The connecting rod 22 is fixedly connected to the connecting and fixing block 21. A slider 23 is fixedly connected to the side of the connecting and fixing block 21 close to the tool holder 1. A slide groove 7 is provided on the side of the tool holder 1 close to the slider 23. The connecting and fixing block 21 is slidably connected to the storage groove 4 through the slider 23 and the slide groove 7. By installing the connecting rod 22 on the connecting and fixing block 21, the connecting and fixing block 21 and the connecting rod 22 are connected as a whole. The slider 23 is installed on the connecting and fixing block 21, and a slide groove 7 is provided on the tool holder 1, so that the connecting and fixing block 21 is convenient to be removed from the tool holder 1, and then the tool body 31 is convenient to be removed from the tool holder 1.

[0031] like Figure 4 As shown, the cutter head assembly 3 includes a cutter body 31 and a limiting rod 32. The cutter body 31 is arranged inside the storage groove 4 near the side of the connection fixing block 21. The limiting rod 32 is fixedly connected to the side of the cutter body 31 near the cutter seat 1. A limiting groove 5 is provided on the side of the cutter seat 1 near the limiting rod 32. The cutter body 31 is clamped with the cutter seat 1 through the limiting rod 32 and the limiting groove 5. By installing the limiting rod 32 on the cutter body 31 and providing the limiting groove 5 matching the limiting rod 32 on the cutter seat 1, it is convenient for the cutter body 31 to be installed or removed on the cutter seat 1 through the limiting groove 5.

[0032] An elastic fixing block 6 is fixedly connected to one side of the tool holder 1 close to the connecting fixing block 21, and a fixing groove 24 is provided on one side of the connecting fixing block 21 close to the elastic fixing block 6. The connecting fixing block 21 is clamped with the tool holder 1 through the fixing groove 24 and the elastic fixing block 6. By installing the elastic fixing block 6 on the tool holder 1 and opening a fixing groove 24 matching the elastic fixing block 6 on the connecting fixing block 21, the elastic fixing block 6 is clamped inside the fixing groove 24, thereby fixing the connecting fixing block 21 on the tool holder 1.

[0033] A second slide groove 25 is provided on one side of the connecting and fixing block 21 close to the fixing groove 24. The second slide groove 25 is slidably connected to the elastic fixing block 6. The depth of the second slide groove 25 is less than the depth of the fixing groove 24. By pulling the connecting and fixing block 21, the elastic fixing block 6 is squeezed, so that the connecting and fixing block 21 slides along the elastic fixing block 6 through the second slide groove 25. After the second slide groove 25 is separated from the elastic fixing block 6, the connecting and fixing block 21 can be taken out from the tool holder 1.

[0034] A rubber pad 26 is fixedly connected to one side of the connecting and fixing block 21 close to the blade body 31. By installing the rubber pad 26, the connecting and fixing block 21 is inserted into the interior of the storage groove 4 so that the rubber pad 26 contacts the blade body 31. The rubber pad 26 is squeezed between the connecting and fixing block 21 and the blade body 31, and the blade body 31 is fixed between the blade holder 1 and the connecting and fixing block 21, thereby reinforcing the blade body 31 to prevent the blade body 31 from being offset during cutting and affecting the cutting.

[0035] A discharge port 8 is provided at one side of the bottom of the tool holder 1 close to the receiving groove 4, and the discharge port 8 is fixedly connected to the receiving groove 4. By providing the discharge port 8, debris on the surface of the tool holder 1 can be discharged from the discharge port 8 to avoid accumulation of debris.

[0036] Working principle:

[0037] like Figure 1-5 As shown, after the cutting tool has been used for a long time, the tool body 31 needs to be replaced. First, the connecting and fixing block 21 is pulled, and the connecting rod 22 drives the multiple connecting and fixing blocks 21 to be lifted, so that the connecting and fixing block 21 slides along the slide groove 1 7 through the slider 23. At this time, the elastic fixing block 6 on the tool holder 1 is squeezed by the fixing groove 24, so that the elastic fixing block 6 is slidably connected with the slide groove 25. The connecting and fixing block 21 is continued to be pulled to separate the slide groove 25 from the elastic fixing block 6, and the connecting and fixing block 21 is removed from the tool. The knife body 31 is removed from the knife seat 1, thereby facilitating the removal of multiple connection and fixing blocks 21 from the knife seat 1 at the same time, pulling the knife body 31 to separate the limiting rod 32 from the limiting groove 5, removing the knife body 31 from the knife seat 1, and installing a new knife body 31 on the knife seat 1, and then pressing the connection and fixing block 21 downward to make the connection and fixing block 21 snap-fitted to the knife seat 1. At this time, the rubber pad 26 is located between the connection and fixing block 21 and the knife body 31, pressing the knife body 31 tightly against the knife seat 1, thereby fixing the knife body 31.
