[0002] Chisel is one of the most important tools in the chiseling process, and its quality directly affects the chiseling effect. Chisel is usually made of high carbon steel or alloy steel, with the characteristics of sharpness, high hardness, and wear resistance. According to different chiseling needs, there are many different types of chisel, such as flat-blade, round-blade, bevel-blade, etc. When using, you should choose the appropriate knife type according to your needs and keep the blade sharp. The chisel hammer is a tool used to strike the chisel during the chiseling process. Its weight and size will affect the strength and effect of the strike.

[0003] Traditional chiseling knives have the following problems when used:

[0004] 1. Traditional chisels require the purchase of many heads to handle various turns, curved surfaces, straight lines, etc.

[0005] 2. Traditional chiseling knives require one hand to hold the knife and the other hand to hold the hammer. Only by controlling the force of the strike and the speed of the knife can a good production effect be achieved, which is very difficult for novices;

[0006] 3. To achieve a three-dimensional effect with a traditional chisel, both sides of the chisel need to be used, and it needs to be struck repeatedly;

[0007] 4. No matter how skilled you are at using a traditional chisel, the knife marks will not be smooth when magnified. Utility Model Content

[0008] In order to overcome the above-mentioned shortcomings of traditional chiseling knife engraving, the utility model provides a handheld engraving and embossing knife, which can make the workpiece engraving process more coherent and smooth.

[0009] The technical solution is: a handheld carving and embossing knife, characterized in that it includes a handle and a knife head, the handle and the knife head are connected by a detachable fixed structure, the knife back of the knife head is an inverted triangle, the blade surface of the knife head is also an inverted triangle, and the blade extends downward to connect with the center line of the knife back.

[0010] As a further preferred solution, the thickness of the blade back in the lower half of the blade head is thicker than the thickness of the blade in the lower half of the blade head.

[0011] As a further preferred embodiment, the thickness of the blade back in the upper part of the blade head is the same as the thickness of the blade edge in the lower part of the blade head.

[0012] As a further preferred embodiment, the fixing structure includes a fixing rod fixed at the bottom of the tool handle, a guide plate connected to the bottom end of the fixing rod, a fixing head fixed at both ends outside the guide plate, a threaded sleeve rotatably connected to the top of the fixing head, a diamond block slidably connected to the fixing rod and the tool handle, a bolt fixed at the bottom of the diamond block, two clamps slidably connected to the guide plate, and an oblique groove opened at the bottom of the bolt, wherein the threaded sleeve is threadedly connected to the bolt, and the upper part of the clamp is inserted into the oblique groove.

[0013] As a further preferred solution, the outer side of the threaded sleeve is provided with anti-slip grooves.

[0014] As a further preferred solution, the lower parts of the two clamps are respectively in contact with the two side surfaces of the cutter head, and the two clamps are close to each other to limit and clamp the cutter head.

[0015] The utility model has the following advantages: the blade back and the blade surface of the cutter head of the utility model are both set to inverted triangles, so that the thickness of the blade back and the blade surface at different positions are different. When engraving, by adjusting the contact part between the blade back or the blade surface and the workpiece, various turning, curved and straight line engravings can be achieved. Compared with percussion engraving, the utility model can be completed by holding the knife with one hand, and the engraving process is smoother; through the setting of the fixed structure, the direct disassembly and installation of the cutter head and the handle can be made more convenient and quick.

[0020] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Embodiment: This embodiment provides a hand-held carving embossing knife, such as Figure 1-Figure 3 As shown, it consists of a handle 1 and a cutter head 3, and a fixed structure for connecting the two. The back of the cutter head 3 is an inverted triangle, and the blade surface of the cutter head 3 is also an inverted triangle, and the blade extends downward to connect with the center line of the back of the cutter head 3. The thickness of the back of the cutter head 3 and the blade surface at different positions are different. The thickness of the back of the cutter head 3 is thicker than the blade thickness of the lower half of the cutter head 3, and the thickness of the back of the cutter head 3 in the upper half is the same as the blade thickness of the lower half of the cutter head 3. The fixed structure includes a fixed rod 6, a guide plate 7, a fixed head 8, a threaded sleeve 9, a diamond block 10, a bolt 11 and a clamping plate 12. The fixed rod 6 is fixedly arranged at the bottom of the handle 1, and the guide plate 7 is fixedly arranged at the bottom end of the fixed rod 6. The fixed heads 8 are fixedly arranged at both ends of the guide plate 7. The cutter head 3 is slidably arranged at the bottom of the fixed head 8, and a threaded sleeve 9 is rotatably arranged on the top of the fixed head 8. The threaded sleeve 9 can rotate between the fixed head 8 and the bottom end of the handle 1, and the outer side of the threaded sleeve 9 is provided with anti-slip patterns, diamond blocks 10, bolts 11 and clamping plates 12. The block 10 is slidably arranged on the fixing rod 6 and is slidably matched with the tool handle 1 at the same time. A bolt 11 is fixedly arranged at the bottom of the diamond block 10. The bolt 11 and the threaded sleeve 9 are rotated through a thread, and two inclined grooves 13 are symmetrically provided at the bottom of the bolt 11. Two clamping plates 12 are symmetrically slidably arranged on the guide plate 7. The upper parts of the two clamping plates 12 are respectively inserted into an inclined groove 13, and the lower parts of the two clamping plates 12 are respectively fitted with the two side surfaces of the cutter head 3. When the engraver rotates the threaded sleeve 9 clockwise, the bolt 11 will rotate downward and drive the diamond block 10 to slide downward. The inclined groove 13 on the bolt 11 will immediately force the two clamping plates 12 to approach each other, limit the clamping of the cutter head 3, and complete the fixation of the cutter head 3. When the cutter head 3 is damaged, the threaded sleeve 9 is rotated counterclockwise to make the bolt 11 and the diamond block 10 rise, and the two clamping plates 12 are away from each other, and the cutter head 3 can be pulled out from the fixed head 8 for replacement, and only the cutter head 3 needs to be replaced, which can reduce the production cost.

[0022] When the engraver uses the present application to engrave a workpiece, he can hold the engraving and embossing knife in one hand to operate it. When encountering turning points or curved surfaces during engraving, and when engraving grooves of different widths, by adjusting the position of the cutter head 3, the contact part between the back of the knife or the blade and the workpiece is changed. The workpiece can be engraved using parts of the cutter head 3 of different thicknesses, making the overall engraving process coherent and smooth, and the engraving effect is more delicate than the traditional percussion engraving method. When a gap appears on the back of the knife or the blade of the cutter head 3 and needs to be replaced, the handle 1 is separated from the cutter head 3 through the fixed structure, and the new cutter head 3 can be replaced.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
