[0025] The inclined surface 15 is arranged on the side close to the grinding wheel 10, a wire hole 17 is opened inside the support block 12, the support block 12, the angle adjustment bracket 9 and the hollow shaft 13 are arranged on the same axis, the first bracket 1 is connected to the first motor 7 through a plurality of screws 8, a plurality of grooves are opened on the first bracket 1, the first bracket 1 is connected to a protective case 2 through a plurality of threaded rods 4, and a plurality of installation grooves are opened on the first bracket 1.

[0026] In this utility model, the first motor 7 is mounted on the first bracket 1 through screws 8. The driving end of the first motor 7 is connected to the hollow shaft 13. The hollow shaft 13 is installed and connected to the lower end of the angle adjustment bracket 9. The side of the angle adjustment bracket 9 has bolt holes. By passing one end of the bolt 3 through the corresponding bolt hole and threadedly connecting it to the second bracket 11, the angle of the second bracket 11 can be fixed and adjusted. A second motor 16 is fixedly installed inside the second bracket 11. The driving end of the second motor 16 is fixedly connected to a grinding wheel 10. The angle between the grinding wheel 10 and the inclined surface 15 can be changed by adjusting the angle of the second bracket 11, and the needle tip at any angle can be ground.

[0027] In this utility model, the first bracket 1 is installed with the first motor 7 through a plurality of screws 8, which can firmly connect the first motor 7 and the first bracket 1. A plurality of installation grooves are provided on the first bracket 1. The first bracket 1 installs and fixes the protective shell 2 through a plurality of threaded rods 4. Each threaded rod 4 passes through the protective shell 2 and is threadedly connected to the installation groove on the first bracket 1. The protective shell 2 is installed outside the first motor 7, and the protective shell 2 can provide good protection for the first motor 7 and the conductive slip ring 6.

[0028] In this utility model, during use, first connect the power supply. The conductive slip ring 6 supplies power to the second motor 16 through the power cord 5. The second motor 16 drives the grinding wheel 10 to rotate together. Then, the first motor 7 is powered on. After the first motor 7 is powered on, it will drive the angle adjustment bracket 9 and the second motor 16 to rotate together. At this time, one end of the metal wire is fixed, and the other end is sent through the wire hole 17 in the support block 12 to the intersection of the inclined surface 15 and the grinding wheel 10. During this process, the inclined surface 15 of the support block 12 can make the metal wire fit with one side surface of the grinding wheel 10. The support block 12 provides a supporting effect on the metal wire. The grinding wheel 10 rotates self - driven under the drive of the second motor 16. The first motor 7 drives the second motor 16 and the grinding wheel 10 to grind around the metal wire until the end of the metal wire is sharp, thus realizing the 360 - degree sharpening process. During the operation of the equipment, the conductive slip ring 6 and the hollow shaft 13 rotate relative to each other, which can effectively prevent the power cord 5 from getting wound. Using the grinding wheel 10 can effectively prevent the problem that the needle tip of the metal wire breaks and gets stuck in the blade angle.

[0029] In this utility model, the grinding wheel 10 used is a standard - specification grinding wheel on the market. Its advantage is that the cost of replacing the grinding wheel is lower than that of replacing the blade. There is a complete variety of grinding wheels, and the appropriate grinding wheel material can be selected according to different materials of metal wires, including but not limited to the above - mentioned metal wires such as copper, iron, aluminum carbon steel, stainless steel, tungsten needles. Both hard and soft metal wires can be sharpened, which is beneficial to the grinding process of metal wires.

[0030] In the present utility model, a through hole 14 is formed at the upper end of the angle adjustment bracket 9 for clamping and fixing the support block 12. There is a wire hole 17 inside the support block 12. An appropriate support block 12 can be selected according to the wire diameter of the metal wire. The support block 12, the angle adjustment bracket 9, and the driving end of the first motor 7 are on the same axis. During the grinding process, the first motor 7 drives the hollow shaft 13, and the hollow shaft 13 drives the angle adjustment bracket 9 and the support block 12 to rotate synchronously, so as to grind around the metal wire. There is an inclined surface 15 on the side of the support block 12. The metal wire is in contact with the surface of the grinding wheel 10. The inclined surface 15 of the support block 12 provides a supporting force for the metal wire, which can grind and sharpen the metal material with a small wire diameter and can also be used for the processing of high-precision medical metal wires.
