The invention discloses an easy-to-assemble two-stage speed change clutch of an automobile cooling system. The clutch comprises a spindle penetrating through an outer support and a transmission wheel and a clutch device sleeving the end part of the outer support; a magnet structure is arranged in a hollow cavity formed by the inner annular surface of the transmission wheel and the spindle, wherein a magnetic pole of the magnet structure is arranged on the peripheral surface of the magnet structure, and the magnet structure comprises an annular magnet sleeving the spindle. Such design structure is compact and an axial distance of the clutch is reduced; a magnetic field directly acts on the inner annular surface of the transmission wheel, when the clutch device is powered off and disconnected, the magnet structure drives the spindle to rotate at a low speed, and when the clutch is powered on and connected, the spindle and the transmission wheel rotate synchronously to realize two-stage rotary speed output; one whole annular magnet replaces the embedding manner of small magnets, the falling possibility of the small magnets is avoided, the reliability is good, the step of embedding the small magnets is omitted and the production cost is reduced.

The invention discloses a television and a rotary base thereof. The television comprises a fixed support fixedly connected with a television main body and the rotary base which is connected to the bottom end of the fixed support, is used for supporting the fixed support and is rotatable. By virtue of adopting the rotary base, stable rotation and loosening prevention can be ensured under the action of the gravity of the television; the television can not rotate, but the base can rotate; when the base rotates, obvious gears and a certain rotation angle are achieved, so that production and sale of the television with the base are realized, the damage risk can be avoided in the process of installing the television at a terminal; after the base is rotated, the package size of the whole television is reduced, the package cost is lowered, and the rotary base is especially applicable to large-size televisions, such as televisions of more than 65 inches.
