Abstract
The utility model provides a magnetic holder for a small hexagon nut. The magnetic holder for the small hexagon nut comprises a handle, a connecting rod and an end socket. One end of the connecting rod is fixedly connected with the handle, while the other end of the connecting rod is a hexagonal head; a cylindrical cavity is formed at one end of the end socket, while clamping teeth are formed at the other end of the end socket. A permanent magnet is arranged in the cylindrical cavity; the hexagonal head of the connecting rod is in interference fit with the cylindrical cavity and is used for squeezing and fixing the permanent magnet in the cylindrical cavity; the other side of the permanent magnet is supported and fixed by the clamping teeth which are structured the same as one another and distributed annularly and evenly. The length and the inner prismatic surfaces of the clamping teeth are matched with that of the small hexagon nut. Under the action of the attraction of the permanent magnet, the small hexagon nut is fixed between the clamping teeth.
