Description
Technical Field
[0001] The utility model relates to the technical field of stainless steel knives, and particularly relates to a heat-treated stainless steel knife. Background Art
[0002] The heat treatment of stainless steel knives is to accurately heat the stainless steel knives to a certain temperature through a heating system, and then cool them with an optimized cooling medium to change their internal structure, thereby improving the hardness, wear resistance and toughness of the blades, and enhancing the overall performance and service life of the knives.
[0003] Stainless steel knives are composed of a blade body, a handle and a blade edge. During use, when the blade edge needs to cut relatively hard objects, the blade edge may have notches, resulting in the entire knife being unusable, which is a waste. At the same time, the connection between the handle and the blade body is mostly fixed by glue bonding. This fixing method has poor stability. When exposed to high temperatures, the glue softens and debonds. Also, when the user holds the handle, it is easy to slip due to the wet hands. Therefore, in view of the above problems, we have proposed a heat-treated stainless steel knife. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a heat-treated stainless steel knife to solve the problems that when the blade edge needs to cut relatively hard objects, the blade edge may have notches, resulting in the entire knife being unusable, which is a waste. At the same time, the connection between the handle and the blade body is mostly fixed by glue bonding. This fixing method has poor stability. When exposed to high temperatures, the glue softens and debonds. Also, when the user holds the handle, it is easy to slip due to the wet hands.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A heat-treated stainless steel knife includes a blade body, a blade edge and a handle. The blade edge is provided at the lower end of the blade body, the handle is provided at the left end of the blade body. An insertion slot is opened inside the right end of the handle. An internal thread sleeve is fixedly connected to the inside of the upper end of the handle. The inside of the internal thread sleeve is spirally connected to the outside of a screw rod assembly. The lower end of the screw rod assembly is fixedly connected to a first clamping plate. A second clamping plate is fixedly connected inside the insertion slot. A placement groove is opened inside the lower end of the handle. A compression spring is fixedly connected inside the placement groove. The upper end of the compression spring is fixedly connected to a connection block. One end of the connection block is fixedly connected to an insertion rod assembly. A breathable layer is fixedly connected to the outer wall of the handle. Breathable holes are opened inside the breathable layer. A water-absorbing layer is fixedly connected to the outer wall of the breathable layer. A non-slip layer is fixedly connected to the outer wall of the water-absorbing layer.
[0007] Preferably, the left end of the blade body is located inside the insertion slot. The insertion slot is located above the placement groove. The internal thread sleeve is located above the insertion slot.
[0008] Preferably, the cross-sectional shape of the screw assembly is "T"-shaped, the lower surface of the first clamping plate is closely attached to the upper end of the tool body, and the number of the second clamping plates is two.
[0009] Preferably, the upper end of the second clamping plate is attached to the lower surface of the tool body, the number of the compression springs is two, and the number of the connecting blocks is two.
[0010] Preferably, a placement groove is slidably connected to the outside of the connecting block, the upper end of the plug rod assembly is clamped inside the lower end of the tool body, and the number of the ventilation holes is several.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the present utility model, by setting the internal thread sleeve, the screw assembly, the first clamping plate, the second clamping plate, the compression spring, the connecting block and the plug rod assembly, when the cutting edge has a notch and cannot be used, the screw assembly is rotated outward, and the screw assembly rotates upward along the internal thread sleeve. The screw assembly drives the first clamping plate to rotate upward, and then the plug rod assembly is pulled downward, so that the plug rod assembly leaves the inside of the lower end of the tool body. At this time, the whole tool body can be taken out for replacement, thereby reducing the waste of materials. When replacing, the left end of the new tool body is inserted into the slot, and then the screw assembly is rotated inward. The screw assembly drives the first clamping plate to rotate downward, so that the first clamping plate applies a downward pressure to the tool body and cooperates with the second clamping plate to fix the tool body. When the plug rod assembly is released, at this time, the compression spring provides a reverse acting force to drive the plug rod assembly to move upward through the connecting block, so that the upper end of the plug rod assembly is inserted into the inside of the lower end of the tool body, thereby fixing the tool body again. The fixing effect of the device is stable, it is suitable for use in various environments, and the practicability is relatively high. By setting the breathable layer, the ventilation holes, the water absorption layer and the anti-slip layer, the water absorption layer absorbs the moisture on the hand, and the moisture is dried in time through the breathable layer and the ventilation holes. At the same time, the anti-slip layer can increase the contact area between the hand and the tool handle, reduce slipping, enhance the practicability and improve the use effect.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution:
[0020] A heat-treated stainless steel knife includes a knife body 1, a blade 2 and a handle 3. The lower end of the knife body 1 is provided with the blade 2, the left end of the knife body 1 is provided with the handle 3. A slot 4 is opened inside the right end of the handle 3.

[0021] The left end of the knife body 1 is located inside the slot 4. The slot 4 is located above the placement groove 9. The internal thread sleeve 5 is located above the slot 4. The cross-sectional shape of the screw rod assembly 6 is "T"-shaped. The lower surface of the first clamping plate 7 is closely attached to the upper end of the knife body 1. The number of the second clamping plates 8 is two. The upper ends of the second clamping plates 8 are attached to the lower surface of the knife body 1. The number of the compression springs 10 is two. The number of the connecting blocks 11 is two. The outer sides of the connecting blocks 11 are slidably connected to the placement groove 9. The upper end of the plug rod assembly 12 is clamped inside the lower end of the knife body 1. The number of the ventilation holes 14 is several. The lower end of the knife body 1 is provided with a blade 2. The left end of the knife body 1 is provided with a knife handle 3. A slot 4 is opened inside the right end of the knife handle 3. The inner side of the upper end of the knife handle 3 is fixedly connected with an internal thread sleeve 5, which facilitates the setting of the internal thread sleeve 5, the screw rod assembly 6, the first clamping plate 7, the second clamping plate 8, the compression spring 10, the connecting block 11 and the plug rod assembly 12. When the blade 2 has a notch and cannot be used, the screw rod assembly 6 is rotated outwards. The screw rod assembly 6 rotates upwards along the internal thread sleeve 5. The screw rod assembly 6 drives the first clamping plate 7 to rotate upwards. Then, the plug rod assembly 12 is pulled downwards, so that the plug rod assembly 12 leaves the inside of the lower end of the knife body 1. At this time, the whole knife body 1 can be taken out for replacement, thus reducing the waste of materials. When replacing, the left end of the new knife body 1 is inserted into the slot 4. Then, the screw rod assembly 6 is rotated inwards. The screw rod assembly 6 drives the first clamping plate 7 to rotate downwards, so that the first clamping plate 7 applies a downward pressure to the knife body 1 and cooperates with the second clamping plate 8 to fix the knife body 1. When the plug rod assembly 12 is released, at this time, the compression spring 10 provides a reverse acting force to drive the plug rod assembly 12 to move upwards through the connecting block 11, so that the upper end of the plug rod assembly 12 is inserted into the inside of the lower end of the knife body 1, thereby fixing the knife body 1 again. The fixing effect of this device is stable, suitable for use in various environments, and has high practicability; the inner side of the internal thread sleeve 5 is spirally connected to the outer side of the screw rod assembly 6. The lower end of the screw rod assembly 6 is fixedly connected with the first clamping plate 7. The second clamping plate 8 is fixedly connected inside the slot 4. A placement groove 9 is opened inside the lower end of the knife handle 3. The compression spring 10 is fixedly connected inside the placement groove 9. The upper end of the compression spring 10 is fixedly connected with the connecting block 11. One end of the connecting block 11 is fixedly connected with the plug rod assembly 12. The outer wall of the knife handle 3 is fixedly connected with a ventilation layer 13, which facilitates the setting of the ventilation layer 13, the ventilation holes 14, the water absorption layer 15 and the anti-slip layer 16. The water absorption layer 15 absorbs the moisture on the hand and dries the moisture in time through the ventilation layer 13 and the ventilation holes 14. At the same time, the anti-slip layer 16 can increase the contact area between the hand and the knife handle 3, reduce slipping, enhance practicability and improve the use effect; the ventilation holes 14 are opened inside the ventilation layer 13. The outer wall of the ventilation layer 13 is fixedly connected with the water absorption layer 15. The outer wall of the water absorption layer 15 is fixedly connected with the anti-slip layer 16.
[0022] Workflow: When the device is in use, the blade body 1, the blade edge 2 and the handle 3 form a tool. When the user's hand is wet but needs to use the tool, hold the anti-slip layer 16 with the hand. Then, the water absorption layer 15 will absorb the moisture on the hand, and the moisture will be dried in time through the breathable layer 13 and the ventilation holes 14. The anti-slip layer 16 will increase the contact area between the hand and the handle 3, thus effectively reducing slipping and facilitating use. When the blade edge 2 has a notch and cannot be used, rotate the screw component 6 outwards. The screw component 6 rotates upwards along the internal thread sleeve 5. The screw component 6 drives the first clamping plate 7 to rotate upwards, and then pulls the insertion rod component 12 downwards. The insertion rod component 12 squeezes the compression spring 10 downwards through the connecting block 11, so that the insertion rod component 12 leaves the inner side of the lower end of the blade body 1. At this time, the whole blade body 1 can be taken out for replacement, thus reducing the waste of materials. When replacing, insert the left end of the new blade body 1 into the slot 4, and then rotate the screw component 6 inwards. The screw component 6 rotates downwards along the internal thread sleeve 5. The screw component 6 drives the first clamping plate 7 to rotate downwards, so that the first clamping plate 7 applies a downward pressure on the blade body 1, and the second clamping plate 8 supports the blade body 1, so that the first clamping plate 7 and the second clamping plate 8 cooperate with each other to fix the blade body 1. Then, loosen the insertion rod component 12. At this time, the compression spring 10 provides a reverse acting force to drive the insertion rod component 12 to move upwards through the connecting block 11, so that the upper end of the insertion rod component 12 is inserted into the inner side of the lower end of the blade body 1, thus fixing the blade body 1 again. The fixing effect of this device is stable, suitable for use in various environments, and has high practicability.
