The invention relates to an underwater stretching mechanism. The underwater stretching mechanism comprises a stretching mechanism, a fixed part, a drive part and a transmission part, wherein the transmission part comprises a gear transmission assembly and a screw thread pair. The output torque of the drive part is converted into a liner motion at the moving end of the stretching mechanism throughthe gear transmission assembly and the screw thread pair in sequence, and the opening and closing of the moving end and the fixed end are realized, so that the technical problems of shrinkage and stretching of the underwater stretching mechanism are solved, and then the equipment damage is reduced, and the equipment safety is improved. 本发明涉及种水下伸展机构，包括伸展机构、固定部件、驱动部件以及传动部件，传动部件包括齿轮传动组件和螺纹副，本发明依次通过齿轮传动组件和螺纹副将驱动部件的输出力矩转化成伸展机构活动端的直线运动，实现活动端与固定端的开、合，从而解决了水下伸展机构收缩与伸展的技术问题，进而降低了设备损伤，提高了设备安全性。
