There is a lack of effective tools to deal with narrow edges. During operation, it is difficult to see the inside clearly and it is all based on the feel of the hand, which affects the effect of cultural relics restoration and easily damages the artifact body. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a curved surface grinding tool head for endoscopic restoration of special-shaped cultural relics, and the purpose is to solve the problem that electric tools are large in size and traditional restoration tools such as knives are difficult to grind into the interior of the object.

[0005] The utility model is implemented as follows: a curved surface grinding tool head for endoscopic restoration of special-shaped cultural relics comprises: a gripping block, a notch extending inwardly is provided on one end of the gripping block, positioning posts are fixedly installed on both sides of the notch, and a plurality of positioning posts are provided; a lighting lamp is provided on the gripping block and used for illuminating the cultural relic grinding, and a strap for tying the lighting lamp to the gripping block is provided on the outside of the lighting lamp and the gripping block; a grinding knife, positioning holes are provided on both sides of the grinding knife, the grinding knife can be bent and mounted on the positioning posts through the positioning holes, and is used for grinding the cultural relic; a protective cover is mounted on the notch of the gripping block, and is used to block both sides of the grinding knife to prevent the positioning holes of the grinding knife from popping out of the positioning posts.

[0006] Preferably, the color rendering index of the lighting lamp light source is greater than Ra95, which is used to restore the true color of the cultural relics, and the color temperature of the lighting lamp is 4000K to be close to natural light.

[0007] Preferably, the grinding blade edge is a double-sided design, with the two sides being serrated and flat respectively.

[0008] The curved surface grinding blade head for endoscopic restoration of special-shaped cultural relics provided by the utility model can not only grind the inner wall of the cultural relic, but also has a small size, a strong grip, and an ergonomic design. At the same time, it has a good grinding effect, a fast speed, is relatively clear during grinding, and the grinding blade is easy to replace, and is highly practical.

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.

[0014] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0015] See also Figure 1 and Figure 2 The embodiment of the utility model provides a curved surface grinding blade for endoscopic restoration of special-shaped cultural relics, and the curved surface grinding blade for endoscopic restoration of special-shaped cultural relics includes:

[0016] A holding block 1, wherein a notch 2 extending inward is provided on one end of the holding block 1, and positioning posts 3 are fixedly installed on both sides of the notch 2, and a plurality of positioning posts 3 are provided; an illumination lamp 4 is provided on the holding block 1 and used for illuminating the polishing of cultural relics, and a strap 5 for tying the illumination lamp 4 to the holding block 1 is provided on the outside of the illumination lamp 4 and the holding block 1; a grinding knife 6, wherein positioning holes are provided on both sides of the grinding knife 6, and the grinding knife 6 can be bent and sleeved on the positioning posts 3 through the positioning holes for polishing cultural relics; a protective cover 7 is sleeved on the notch 2 provided on the holding block 1, and used for blocking both sides of the grinding knife 6 to prevent the positioning holes of the grinding knife 6 from popping out of the positioning posts 3.

[0017] When grinding the inside of a cultural relic, just hold the holding block 1 and put the grinding knife 6 into the inside of the cultural relic for grinding. If you want to replace the grinding knife 6, first remove the protective cover 7 from the notch 2, and then remove the positioning hole opened by the grinding knife 6 from the positioning column 3, so that the grinding knife 6 can be replaced. After the new grinding knife 6 is inserted into the positioning column 3 through the positioning hole, the protective cover 7 is then inserted into the notch 2 to ensure the stability of the grinding knife 6 and prevent the grinding knife 6 from detaching from the positioning column 3.

[0018] like Figure 1 and Figure 2As shown, as a preferred embodiment of the utility model, the color rendering index of the light source of the lighting lamp 4 is greater than Ra95, which is used to restore the true color of the cultural relics. The color temperature of the lighting lamp 4 is 4000K to be close to natural light.

[0019] The color rendering index of the light source of lighting lamp 4 is ≥Ra95, which can restore the true color of cultural relics; the color temperature of the light source of lighting lamp 4 is 4000K, which makes lighting lamp 4 closer to natural light. Lighting lamp 4 is powered by button batteries, which is small in size and easy to replace, and does not require a matching power cord or charging kit.

[0020] like Figure 3 As shown, as a preferred embodiment of the present utility model, the edge of the grinding knife 6 is a double-sided design, and the two sides are respectively serrated and flat.

[0021] The grinding knife has a double-sided design with 6 edges. One side is serrated, which can be used to grind hard areas, and the other side is flat, which can be used for grinding and leveling.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
