The utility model discloses an intermediate-frequency pulse therapeutic apparatus with a locking structure, and relates to the technical field of intermediate-frequency pulse therapeutic apparatuses. Comprising an intermediate-frequency pulse therapeutic apparatus main body, the intermediate-frequency pulse therapeutic apparatus main body is provided with an installation mechanism used for an intermediate-frequency pulse therapeutic apparatus line, a sorting shell slides out along a storage shell through a positioning block and a positioning groove, and a pressing rod rotates on the inner wall of the sorting shell through a connecting shaft; then the pulled-out wires are wound on the storage rods respectively, the pressing rods are rotated downwards through the connecting shafts, the wound wires are pressed downwards and fixed, the risk that the wires are scattered, knotted or damaged is avoided, after the wires are compressed and fixed through the pressing rods, the clamping blocks and the clamping grooves are loosened for fixing, fixing of the pressing rods is achieved, and the pressing rods are fixed conveniently. And therefore, the wires can be conveniently carried and stored by a user, and inconvenience in operation or potential safety hazards caused by disorder of the wires are reduced.
