[0002] At present, in the field of laser engraving technology, laser engraving rotary drive devices are generally used to clamp workpieces and perform rolling laser engraving of cylindrical surfaces; for example, the utility model patent "A Rotary Clamp for a Laser Engraving Machine" with application number CN202223204063 provides such a laser engraving rotary drive device.

[0003] However, current laser engraving rotary drive tools are generally inconvenient to use. This is because when using these devices, the user usually needs to support and hold the workpiece with his left hand while turning the chuck's spiral adjustment wheel with his right hand to adjust the movable diameter of the chuck's clamping jaws. At this time, turning the chuck's spiral adjustment wheel tends to move the clamping jaws in the same direction, causing them to rotate simultaneously, making it impossible to adjust the movable diameter of the chuck's clamping jaws relative to each other. Therefore, a second person is required to assist in the operation, which is inconvenient to use. A new laser engraving rotary drive device is needed to solve this problem. Utility Model Content
