The utility model relates to a technical field of jack stretch -draw dowel discloses synchronous stretch -draw dowel structure of a plurality of jack, including the oil pump of construction hole and the work of control jack, many dowels are worn to be equipped with in the construction hole, and each dowel is equipped with the jack respectively, the oil pump intercommunication has divider, each jack of divider synchronous connection, the construction hole is including construction surface who supplies the dowel to wear to establish and the construction wall that encircles encirclement construction surface, and along the direction that deviates from construction surface, the construction wall extends to be arranged, when the jack was established on the dowel, the construction wall encircleedeach jack that surrounds and contradict. When carrying out the synchronous stretch -draw dowel construction of a plurality of jack, the oil pump supplies to press to each jack, because the oil pump intercommunication has the
