A hand tool alternately-magnetizing structure includes a body, at least one magnetic component, and an adjustment ring. The body defines a central axis and a handle portion; in which defines at least one recess dented along a radical direction thereof. The magnetic component is received in the recess of the handle portion, and includes a resilient member and a magnetic member. The adjustment ring is sleeved onto the handle portion and capable of angular displacement. The adjustment ring defines at least one switchable portion dented at an interior wall face thereof for corresponding to the recess of the handle portion. The switchable portion describes an adjacent section and an outlaying section, wherein a wall thickness defined at the adjacent section is greater than that defined at the outlaying section. When the outlaying section of the switchable portion is set to align with the recess of the handle portion, the effective magnetic field of the magnetic member reaches an extramural area, which situates out of the handle portion. On the contrary, when the adjacent section of the switchable portion is set to align with the recess of the handle portion, the effective magnetic field of the magnetic member fades into an intramural area, which situates inside the handle portion. Therefore, due to the radical motion the effective magnetic field of the magnetic member, the hand tool presents a switch of magnetism. |
