Abstract: A magnetic buckle device has a buckle main body and an inserting head. When the inserting head is close to an insertion hole of the buckle main body, the magnetic attraction force between a first component on the inserting head and a second component on the buckle main body can assist with inserting the inserting head into the insertion hole. After the inserting head is inserted to a predetermined position, the magnetic attraction force will keep the buckle main body in an engaged state even without any additional fixing means. When the buckle main body is switched to a disengaged state and the inserting head is moved out of the buckle main body, the magnetic attraction force attracts the inserting head to attach to the buckle main body, and thereby, after moved out, the inserting head cannot move arbitrarily.
