According to the present invention, the operation in the device becomes efficient, and operation may be managed by the restoring member in the simple principle and structure without any additional advancing jack device. Furthermore, it is possible to reduce installation space or cost since the required capacity of the jack device may be reduced on the whole, increase the durability of the device since the concerns of damage to the device element itself, and reduce the cost and time required for conveying the weight body.
