OBJECT DESCRIPTION OF THE INVENTION · TECHNICAL FIELD OF THE INVENTION The present invention relates to a laser level meter, and more particularly to a rotary light-emitting device capable of reducing motor load. [Prior Art] As shown in Fig. 1, a mechanical level adjuster 1 () has a housing u for placing on a placement surface 20, and is mounted in the housing 11 in a rotatable manner. The outer cylinder base 12 is mounted with a motor 13 fixed in the outer cylinder base 12, and the female inner cylinder base 12 is driven by the motor 13 to produce a rotating inner cylinder base 14, one of which is mounted on the inner cylinder base a light-emitting module 15 in the inside of the casing 11 for supplying power to the power source i 6 of the motor casing 3, a set of weights 17 attached to the outer cylinder block 12 and extending downward, and an installation A damping block 18 is located within the outer casing 11 and below the weight 17. The illuminating module 15 has a illuminating member 151, a collimating lens 152 and a 153 153 which are sequentially mounted from the bottom to the top in an inner axis, and is used first. 1 1 is adjusted to a position that can be stably placed on the placement surface 20, and then the power source 16 is activated to cause the motor 13 to drive the inner base 14 and the light-emitting module 15 to rotate, by the gravity of the weight 17 When the inner tube holder 14 and the light-emitting module 15 are automatically adjusted to the horizontal position, the light beam emitted from the crucible 153 can form a horizontal reference line (not shown) on a working surface, and the damping block 18 can Magnetic field damping is generated to help the weight 17 to stabilize quickly. Although the 5th level adjuster 1 has the above-mentioned functions, it still has the following defects in 1288228: 1. The motor 13 must drive the inner tube holder 14 and the light-emitting module 15 to have a large load of the motor 13 . Second, since the weight 17 is easily swayed by external factors, the light beam emitted through the 稜鏡153 will be constantly shaken, and there is a lack of quality of use. Second, because the light-emitting member 151 of the light-emitting module 15 is in a rotating design,
