Problems solved by technology

[0002] The fastening of the screw requires a certain operating space on the screw head, that is, the length of the screwdriver and the handshake space of the screwdriver handle are required to achieve the purpose of holding the screwdriver handle to rotate the fastening screw. However, in some small tables, semi-enclosed spaces To realize the installation of screw fasteners, there is a narrow space above the screw head, the space size is often smaller than the length of the screwdriver, and obstacles are on the upper part of the screw, the screwdriver cannot be aligned vertically with the screw head, and the purpose of holding the screwdriver handle to rotate the fastening screw cannot be achieved
At present, three methods are used to solve this problem: one is to transform the existing screwdriver and process the screwdriver blade into Type, using the corner to avoid obstacles, to achieve the purpose of fastening the screw, the disadvantages of this method are: 1, after the transformation of the two parallel screws perpendicular to the screw head Type of screwdriver, the rod at the blade, because the fastening screw needs a force from the blade of the screwdriver to the screw head, so that the screw can be tightened, and the screw cannot be tightened only by the force of rotation. The downward pressure of the handle end cannot be fully transmitted to the screwdriver at the corner, so the purpose of complete tightening cannot be achieved; 2. The 360-degree rotation angle of the slotted screw during the rotation process, due to the narrow space and obst

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of screw fastening tools, and in particular relates to a fastening aid for screws in a semi-enclosed space of a small table body. Background technique [0002] The fastening of the screw requires a certain operating space on the screw head, that is, the length of the screwdriver and the handshake space of the screwdriver handle are required to achieve the purpose of holding the screwdriver handle to rotate the fastening screw. However, in some small tables, semi-enclosed spaces To realize the installation of screw fasteners, there is a narrow space above the screw head, the space size is often smaller than the length of the screwdriver, and obstacles are on the upper part of the screw, the screwdriver cannot be aligned vertically with the screw head, and the purpose of holding the screwdriver handle to rotate the fastening screw cannot be achieved . At present, three methods are used to solve this problem: ...
