The invention provides a fastening assistive device for a screw in the semi-closed space of a small-sized table body. A driven rod with the upper end and the lower end extending out of a box is rotationally installed on the box body, the lower end of the driven rod is matched with a notch in the head end face of the screw and one end of a staggered shaft rotating transmission device perpendicular to the driven rod is arranged in the box body and connected with the driven rod; and the other end of the staggered shaft rotating transmission device extends out of the box body and is driven by a rotary driving piece adaptively connected with the end part of the staggered shaft rotating transmission device to rotate to drive the driven rod to rotate, and a power assisting piece for providing downward pressure for the driven rod is mounted at the upper end of the driven rod in a height-adjustable manner. According to the fastening assistive device, the driven rod is driven to rotate by the rotary driving part matched with the staggered shaft rotating transmission device, a rotary basis is provided for the screw, downward pressure is provided for the screw by the power assisting piece mounted at the upper end of the driven rod and with an adjustable height, the screw is fastened in the semi-closed space, and product assembly and maintenance quality and production efficiency are improved.
