Embedded supporting component

The utility model discloses a pre-embedded support member, which belongs to the technical field of photovoltaic pile construction tools, and comprises a pouring shell, a pre-embedded support part, a limiter and a clamping part, the central axis of the limiter coincides with the axis of the pouring shell, a plurality of sliding rods are uniformly arranged outwards along the radial direction, any one sliding rod is suitable for abutting against the upper end face of the pouring shell, and the clamping part is used for clamping the limiting stopper. And the lock sleeve is arranged and used for fixing the pre-embedded supporting piece, so that the fixed pre-embedded supporting piece can be embedded into cement along the axis position of the pouring shell. When the embedded supporting piece is fixed, the upper portion of the embedded supporting piece is inserted and fixed into the lock sleeve, after cement is poured into the pouring shell, in order to effectively fix the limiting stopper on the upper end face of t
