The invention relates to a telescopic steel bar connecting external member. An external member body comprises a bidirectional thread sleeve, a forward spinning screw rod seat, a reverse spinning screw rod seat, screw connectors, one-way thread sleeves and pin shafts. An internal thread at one end of the bidirectional thread sleeve is consistent with internal threads of the one-way thread sleeves, and the forward spinning screw rod seat, the screw connectors and external threads headed and turned by steel bar heads are consistent. All the components in the external member can be organically combined, for example, the components are increased or reduced, two steel bar heads with different intervals are in butt joint, and the external member for connection of the steel bar heads on a construction site is provided. The telescopic steel bar connecting external member has the advantages that the combining mode is flexible, according to the needs for steel bar intervals, short-distance connection can be achieved by reducing the components, the needs for long-distance connection can be met by adding the components connected in series, and connecting clearances are tightened and eliminated through the bidirectional thread sleeve; connection is reliable, no deformation exists, the requirement for stress design can be met, the telescopic steel bar connecting external member meets the connection needs of two staggered steel bar heads with different included angles, and connection construction of the steel bars is greatly facilitated.
