A clamping triaxial seepage and acoustic coupling rock tensile testing machine includes a sample and a scaffold-type tensile testing device. The scaffold-type tensile testing device has an upper chuck and a lower chuck. The upper chuck has an acoustic transmitting channel, one end of which communicating with the outside, and the other end of which having an acoustic transmitting probe. The lower chuck has an acoustic receiving channel, one end of which communicating with the outside, and the other end having acoustic receiving probe. An upper end face of the sample has with a seepage outflow hole while the upper chuck has a seepage outflow channel connected with the seepage outflow hole. A lower end face of the sample has a seepage inflow hole while the lower chuck has a seepage entry channel is connected with the seepage inflow hole.
