Abstract: A rock direct tensile test platform suitable for all material test machines includes a support frame. A top of the support frame is fixed with a top plate, and a bearing plate is provided above the top plate. The bearing plate is provided with a plurality of vertical force transferring rods. The force transferring rods vertically penetrate through the top plate and have a sliding fit with the top plate. Lower ends of the force transferring rods are provided with a tensile base. A top of the tensile base is provided with a lower clamp holder. A bottom of the top plate is provided with an upper clamp holder, and a clamp center of the upper clamp holder coincides with a clamp center of the lower clamp holder.
