Improved crank for doors, characterized by comprising a fixed disk that supports a spring that surrounds the square as drive shaft, this disk being found, mounted integrally to the plate or shield, between it and the door, presenting the fixed disk in one of its planes, a perpendicular projection, on whose sides they support the curved ends of the helical spring that surrounds the square, having a rotating disc, provided for this purpose in its center, with a quadrangular through hole, through which the square fits snugly, joining in its rotation, whose rotating disc, comprises a projection facing the projection of the fixed disc but of smaller radius, so that the rotation of the disc forces to displace one of the ends of the spring, obtaining its tensioning.
