Interlocking fitness roller
An interlocking fitness roller is disclosed. The ends of a column-shaped roller body comprise retaining holes and locating holes. A hollow cylindrical assembly is inserted into a hollow interior of the column-shaped roller body. The hollow cylindrical assembly connects with elastic pieces, and each elastic piece comprises a retaining block and a positioning pin, which are respectively engaged with the retaining hole and the locating hole of the column-shaped roller body. The surface of the column-shaped roller body is covered by a pad. Accordingly, depending on different uses, the length of the interlocking fitness roller is adjustable. Two column-shaped roller bodies are connected by respectively engaging the retaining blocks and the positioning pins of the elastic pieces with the retaining holes and the locating holes, so as to is prevent the connection from becoming loose during rolling, thereby ensuring the robustness of the connection between the column-shaped roller bodies.
