Description

Technical Field

[0001] The utility model relates to the technical field of engraving, in particular to a micro-engraving tool. Background Art

[0002] Carving refers to cutting or carving wood, stone or other materials into the desired shape. The tools used for this purpose include knives, chisels, gouges, cones, adzes and hammers. Carving tools are commonly used tools for carving. Micro carving is also a kind of carving, so a micro carving tool is needed.

[0003] When performing micro-carving, operators often use corresponding micro-carving tools. Although the existing tools can achieve the purpose of carving, the tool head cannot be replaced during actual use, which reduces the practicality. In addition, the handles are mostly smooth and may slip during carving, affecting the quality of carving. Utility Model Content

[0004] The purpose of the present utility model is to provide a micro-engraving tool to solve the problem raised in the above background technology that operators often use corresponding micro-engraving tools when performing micro-engraving. Although the existing tools can achieve the purpose of engraving, the tool head cannot be replaced during actual use, which reduces the practicality. In addition, the handles are mostly smooth and may slip during engraving, affecting the quality of engraving.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fine engraving tool, comprising a connecting plate, a base plate fixedly mounted on one side of the connecting plate, locking holes being opened at equal distances on the top of the base plate, a horizontal plate located above the base plate being fixedly mounted on one side of the connecting plate, a screw rod being rotatably mounted on the top of the horizontal plate, the bottom of the screw rod passing through the horizontal plate and extending to the bottom of the horizontal plate, a pressure plate being fixedly mounted on the bottom of the screw rod, a turning handle being fixedly mounted on the top of the screw rod, guide rods being movably mounted on both ends of the top of the horizontal plate, the bottom of the guide rod passing through the horizontal plate and fixedly connected to the top of the pressure plate, a limit plate being fixedly mounted on the top of the guide rod, and a locking rod being fixedly mounted at equal distances on the bottom of the pressure plate.

[0006] Preferably, a storage groove is provided on one side of the connecting plate, and a round rod is movably installed inside the storage groove.

[0007] Preferably, a mounting block is fixedly mounted on one side of the round rod, and vertical grooves are provided at equal distances on the top of the mounting block.

[0008] Preferably, a square plate is fixedly mounted on one side of the mounting block, and a cutter head is fixedly mounted on one side of the square plate.

[0009] Preferably, a knife handle is fixedly mounted on the other side of the connecting plate, mounting grooves are provided at equal distances on the surface of the knife handle, anti-slip pads are fixedly mounted inside the mounting grooves, and anti-slip grooves are provided around the surface of the knife handle.

[0010] Preferably, a hanging plate is fixedly mounted on the other side of the knife handle, and a round hole is opened on the top of the hanging plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] During daily use of this fine engraving tool, the operator slides the mounting block, which then drives the round rod to be placed inside the storage slot, and then one side of the square plate is placed on one side of the bottom plate and the horizontal plate. At this time, the handle is turned, and the handle drives the lead screw to rotate. Due to the limiting effect of the guide rod and the limiting plate, the lead screw drives the pressure plate to rise and fall, and at the same time, the lead screw drives the locking rod to slide until the bottom of the pressure plate is placed on the top of the mounting block, and then the locking rod is placed inside the locking hole and the vertical slot, and the tool head can be installed, otherwise it can be disassembled.

[0013] During daily use of this micro-engraving tool, the operator will hold the tool handle when engraving. The design of the mounting groove and the anti-slip pad can increase the friction with the palm, and the anti-slip groove can further increase the friction. The anti-slip pad and the anti-slip groove can increase the friction, thereby reducing the slippage during engraving, thereby improving the quality of engraving. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-4 The utility model provides a technical solution: a fine engraving tool, including a connecting plate 1, a bottom plate 2 is fixedly installed on one side of the connecting plate 1, and locking holes 3 are opened at equal distances on the top of the bottom plate 2. The locking holes 3 are adapted to the locking rod 10. A horizontal plate 4 located above the bottom plate 2 is fixedly installed on one side of the connecting plate 1. A screw rod 5 is rotatably installed on the top of the horizontal plate 4. The screw rod 5 is connected to the horizontal plate 4 by a thread. The bottom of the screw rod 5 passes through the horizontal plate 4 and extends to the bottom of the horizontal plate 4. A pressing plate 6 is fixedly installed on the bottom of the screw rod 5. When the screw rod 5 rotates, the pressing plate 6 will slide. A turning handle 7 is fixedly installed on the top of the screw rod 5. Rotating the turning handle 7 will cause the screw rod 5 to rotate. Both ends of the top of the horizontal plate 4 are movable A guide rod 8 is installed, the bottom of the guide rod 8 passes through the cross plate 4 and is fixedly connected to the top of the pressure plate 6. When the pressure plate 6 slides, it will drive the guide rod 8 to slide inside the cross plate 4. A limit plate 9 is fixedly installed on the top of the guide rod 8. When the guide rod 8 slides, it will drive the limit plate 9 to slide synchronously, and a locking rod 10 is fixedly installed at an equal distance on the bottom of the pressure plate 6. When the pressure plate 6 slides, it will drive the locking rod 10 to slide. A storage groove 11 is provided on one side of the connecting plate 1, and a round rod 12 is movably installed inside the storage groove 11. The storage groove 11 is adapted to the round rod 12, and the inner surface of the storage groove 11 and the outer surface of the round rod 12 are rough, which can make the connection between the storage groove 11 and the round rod 12 more secure.

[0021] A mounting block 13 is fixedly mounted on one side of the round rod 12, and a vertical slot 14 is equidistantly provided on the top of the mounting block 13. The vertical slot 14 is adapted to the locking rod 10. A square plate 15 is fixedly mounted on one side of the mounting block 13, and a cutter head 16 is fixedly mounted on one side of the square plate 15. When the mounting block 13 slides, it drives the square plate 15 and the cutter head 16 to slide, and then the cutter head 16 is used for engraving. A knife handle 17 is fixedly mounted on the other side of the connecting plate 1. The sliding knife handle 17 drives the connecting plate 1 to slide. The surface of the knife handle 17 is equidistantly provided. There is a mounting groove 18 on the left side, and an anti-slip pad 19 is fixedly installed inside the mounting groove 18. Due to the design of the mounting groove 18, the anti-slip pad 19 can be easily installed, and the surface of the handle 17 is surrounded by an anti-slip groove 20.
