The coupling between the handle and the float includes a plug and socket connection provided with a detent sleeve which holds related pin and slot parts in engagement. The coupling also provides a tilt control including a shaft connected to the end of the handle and relatively rotatable therewith. The shaft is axially rotatable about its own axis and is pivotally connected to the float. A pair of cables reversely wound on the shaft and secured to spaced points on the float changes the angle of tilt as the handle is rotated.，下面是Concrete finishing float专利的具体信息内容。
