The invention provides a small size object hoisting machine which comprises an additional weight base, a supporting piece, an electric stretchable rod and a lifting mechanism. The supporting piece isrotationally installed on the additional weight base and can be stressed to rotate around a vertical axis; one end of the electric stretchable rod is rotationally installed on the supporting piece, and the other end of the electric stretchable rod is connected with a limiting ring; the lifting mechanism comprises a driving motor, a traction rope rolling wheel, a traction rope, a hook and a limiting piece, and the driving motor is installed on the additional weight base or the supporting piece and is connected with the traction rope rolling wheel to drive the traction rope rolling wheel to rotate; one end of the traction rope is wound on the traction rope rolling wheel, and the other end of the traction rope is wound around the top of the supporting piece and penetrates the limiting ring tobe connected with the hook; and the limiting piece is installed on the traction rope and is located between the hook and the limiting ring, the limiting piece can be matched with the limiting ring toprevent the limiting piece from penetrating the limiting ring. The small size object hoisting machine can improve the stability of materials in the rising process.
