Description

Technical Field

[0001] This utility model relates to the field of paper cultural relic restoration technology, specifically a fixing clamp for paper cultural relic restoration. Background Technology

[0002] Paper artifacts include ancient documents, archives, books, and paintings. The preservation of paper artifacts is related to acidity, microorganisms, temperature, humidity, and gases. The acidity of paper is sometimes due to deterioration over time, and sometimes it is left over from the manufacturing process. When restoring paper artifacts, it is necessary to use clamps to fix them in place.

[0003] For example, application number 201920289042.X discloses a fixing clamp for the restoration of paper cultural relics, including a tabletop, table legs, a load-bearing plate, a baffle, a rotary motor, a load-bearing block, a fixing rod, and a rotating device. Table legs are welded to the four corners of the bottom of the tabletop, and a load-bearing plate is welded to the bottom inner side of the table legs. A baffle is welded to the top of the tabletop. A rotary motor is fixed to one side of the upper surface of the load-bearing plate by bolts. The device is equipped with an arc-shaped clamp. By fixing the arc-shaped clamp to the rotating device, the ancient cultural relics can be clamped by the arc-shaped clamp after being placed on the rotating device, so that the ancient cultural relics are not easily broken during the rotation.

[0004] However, while this type of fixing clamp for paper artifact restoration can effectively fix paper artifacts during restoration, the length of the limiting rod is often fixed and cannot be adjusted according to the width of the paper artifact.
