The slope sediment leveler can level out sediments on the oblique face, and the leveling effect is good.

The invention discloses a crystal merry-go-round music box. The music box comprises a base; a cavity is formed in the base; a power device is arranged in the cavity; and a main shaft drives fan bladesto rotate for driving liquid with sequins to rotate so as to produce a beautiful special effect. The music box not only can be watched but also can be played; the rotation of wooden horses can be watched, splendid music can be listened to, and the flying sequins also can be seen; the defect that a traditional crystal ornament is single in function is overcome; and the possibility of errors is reduced through mechanical transmission cooperation.

The invention provides a mechanical transmission structure of an electronic booster. The mechanical transmission structure of an electronic booster comprises a cylinder, an electric motor booster mechanism on the cylinder, a valve assembly inside the cylinder, a gear sleeve, a sensor, and a controller connected with the electric motor booster mechanism. The valve assembly is axially disposed within the cylinder tube of the cylinder. The valve assembly comprises a valve body, a push rod and an output rod, wherein the front end of the valve body is connected with the end of the push rod, and theend of the valve body is connected with the front end of the output rod, and the front end of the push rod is connected with the brake pedal, and the end of the output rod is connected with the brakemaster cylinder. The gear sleeve is arranged on the periphery of the valve body and abuts on the mesa of the boss on the outer wall of the end of the valve body. The connection mode enables the gearsleeve to drive the whole valve assembly to move along the axial direction of the end, and the valve assembly can move along the axial direction of the end without the gear sleeve after being forced.The mechanical transmission structure of an electronic booster is used for an electronic intelligent boosting system driven by a motor, and can play a boosting role when the boosting system works normally. The brake system can also be used to complete the brake when the booster system is abnormal or malfunctioning.
