    • A floor tool is provided, and includes a handle with first and second opposite ends through which a longitudinal axis of the handle extends, and a mop head coupled to the second end of the handle. In some embodiments, a fluid container is coupled to and carried by the handle at a location between the first and second ends of the handle. The fluid container can have a center of mass offset from the longitudinal axis. In some embodiments, a portion of the handle is located between the fluid container and the first end of the handle, and is offset from the longitudinal axis more than center of mass of the fluid reservoir. The floor tool can also have a valve coupled to the handle and having a gap into which a length of conduit extending from the fluid container can be laterally inserted. A valve-actuating trigger can be coupled to the handle for rotation, such that the trigger pivot point is closer to the second end of the handle than the terminal end of the trigger squeezed by a user.
    • 提供了一种地板工具,并且包括具有第一和第二相对端的手柄,手柄的纵向轴线通过该手柄延伸,以及联接到手柄的第二端的拖把头。 在一些实施例中,流体容器在手柄的第一和第二端之间的位置处联接到手柄并由手柄承载。 流体容器可以具有从纵向轴线偏移的质心。 在一些实施例中,手柄的一部分位于流体容器和手柄的第一端之间,并且比纵向轴线偏离流体储存器的质心。 地板工具还可以具有联接到手柄的阀,并且具有间隙,从流体容器延伸的导管的长度可横向插入该间隙。 阀致动触发器可以联接到手柄以进行旋转,使得触发器枢转点比触发器被触发器的终端更靠近手柄的第二端。

    • A socket and ratchet wrench comprises: an annular-toothed block rotatably received in a wrench body, and a socket. The annular-toothed block has a through engaging hole defined with multiple ribs each connected by a negative arc surface, the respective ribs includes two flat first engaging surfaces and one cambered second engaging surface connected the first engaging surfaces by an arc surface. At a first end of the socket are formed multiple grooves for mating with the respective ribs of the annular-toothed block, and at the second end are provided multiple planes for engaging with the second engaging surfaces of the respective ribs.
    • 插座和棘轮扳手包括:可旋转地容纳在扳手主体中的环形齿条和插座。 环形块具有通过接合孔,该通孔由多个肋构成,每个肋由负弧面连接,相应的肋包括两个平坦的第一接合表面和一个弧形的第二接合表面,其通过弧形表面连接第一接合表面。 在插座的第一端形成有用于与环形齿条的各个肋配合的多个凹槽,并且在第二端设置有多个用于与各个肋的第二接合表面相接合的平面。
