| 專利摘要 | An underwater clamp-type release apparatus has a main body and a release mechanism. The main body includes a housing, a motor stand, and a speed reducing gear motor while the release mechanism includes a base plate, a pair of clamp frames, a clamp, and a rotationally controlled block. The clamp is positioned between the two clamp frames and is pivotally connected to the clamp frames with a pin installed through holes in the clamp and the clamp frames. The top end of the clamp has a concave part for clamping and holding the working piece. The rotationally controlled block includes a bottom block, and an annular wall wherein the size of the inner diameter of the annular wall can just fit to contain the second end of the pair of the clamp arms when they are closed, and wherein the annular wall includes two openings opposite each other (180-degrees apart), and the total width of the second end of the clamp arms when they are closed allows them to pass through the openings when the two clamp arms are tending to open. Therefore, when the rotationally controlled block is controlled to turn an angle of 90-degrees, the two clamp arms are aligned with the openings at the rotationally controlled block to be opened, and the working piece is released. |
