Abstract: Disclosed is a movable type magnetic suspension apparatus, comprising: a suspension body (1) having a magnet (2); and a magnetic suspension base (3), the magnetic suspension base comprising: a magnetic suspension mechanism (4) for suspending the suspension body at a predetermined distance thereabove; and a displacement mechanism for displacing the magnetic suspension mechanism to cause the suspension body in a suspended state to displace. The movable type magnetic suspension apparatus enables the suspension body to move in air along a predetermined trajectory and can substantially expand application fields of the magnetic suspension apparatus.

Abstract: A rotary lamp holder comprises a housing having a first longitudinal end and a second longitudinal end, the first longitudinal having an opening, a motor stator disposed around the inner circumference of the housing, a rotating shaft and rotatably mounted in the housing, the rotating shaft defining a cavity in communication with the opening of the first longitudinal end, a motor rotor fixed to the rotating shaft and coaxially disposed with the motor stator, a lamp cover bracket rotatably mounted relative to the housing and extending out of the first longitudinal, and a reduction transmission system located in the housing and connected to the rotating shaft and the lamp cover bracket respectively. Since the rotary lamp holder is compact in structure and size and can completely match any standard lamp holder and lamp cover, it can become a universal substitute for the lamp holder mounted on ordinary lamps.
