Patent ID: 7440689

Claim:
An electromagnetically actuated adjusting apparatus, comprising: a body; at least one permanent magnet adjoined to the body and having a first pole and a second pole opposing each other on each side of the permanent magnet; a first magnetic conductor wound with a plurality of coils and having at least one first extension member which corresponds to the first pole; and a second magnetic conductor wound with a plurality of coils and having at least one second extension member which corresponds to the second pole, wherein a hollow sleeve is further arranged outside the body with an inclined guide groove disposed thereon at a location corresponding to the permanent magnet so as to confine and guide the permanent magnet to undergo oblique linear motion alone the extension of guide groove; the first and second magnetic conductors are disposed encircling a periphery of the sleeve and render the first extension member and the second extension member situated at each end of guide groove to correspond to the two poles of permanent magnet; wherein when predetermined current is applied to the coils, the first and the second magnetic conductors will produce magnetic flux lines which converge in the vicinity of the two poles of permanent magnets to propel the permanent magnet to undergo oblique motion along the guide groove and hence drive the body to undergo threading like displacement in the sleeve.
