Formwork for pouring construction

The invention relates to the field of building construction, in particular to a formwork for pouring construction. The formwork for pouring construction comprises a formwork assembly, adjusting gear levers and a driving unit, the four adjusting gear levers are adjusted to enter corresponding adjusting grooves, when a connecting block abuts against the positions of the adjusting gear levers, the adjusting gear levers prevent the connecting block from sliding along the first transverse edge of a sliding plate, and along with driving of the driving unit, the connecting block can slide along the first transverse edge of the sliding plate. A first elastic piece arranged between the first vertical edge of each sliding plate and a first abutting plate is compressed, and the distance between the first vertical edge of each sliding plate and the inner side wall of the adjacent sliding plate is further reduced, so that a second limiting block gradually slides out of a second limiting groove and enters a first limiting
