    • The present invention provides a hand tool with reliable connections comprising: a working unit having a working end and a handle end opposite to the working end; a handle being mounted on the handle end of the working unit and having a working unit end and a knocking unit end; a knocking unit being mounted on the knocking unit end of the handle. The connecting part between the knocking unit and the handle end of the working unit is a contacting surface, the handle end or the contacting surface is configured as a deformable and non-rigid contact, realizing the reliable connection between the working unit and the knocking unit. The deformable and non-rigid contact is realized by the configuration of at least one of the contacting surface and the handle end being configured to be tooth-shaped, the tooth-shape can deform and form a gapless engagement with the contacting surface. This configuration lowers the precision requirements for the production of each part; saves the costs; achieves reliable connections among the working unit, knocking unit and the handle of the hand tool; and disperses the impact force that damages the handle.
    • 本发明提供一种具有可靠连接的手持工具,包括:工作单元,其具有工作端和与工作端相对的手柄端; 手柄安装在工作单元的手柄端部上并具有工作单元端部和敲击单元端部; 敲击单元安装在手柄的敲击单元端部上。 敲击单元与工作单元的手柄端之间的连接部分为接触表面,手柄端或接触表面被配置为可变形且非刚性的接触,实现了工作单元与敲击单元之间的可靠连接 。 可变形和非刚性接触通过接触表面和手柄端部中的至少一个被构造成齿形的构造来实现,齿形可以变形并且形成与接触表面的无缝接合。 这种配置降低了每个零件生产的精度要求; 节省成本; 实现工作单元,敲击单元和手持工具手柄之间的可靠连接; 并分散破坏手柄的冲击力。

    • The object of the present invention is to provide an ergonomical and practical, handle-equipped universal striking tool with exchangeable tool bits for use when centre-punching, driving cotter pins and nail heads and driving in clips of various kinds, i.e. for such activities where today a hammer is used for striking a separate thumb-grip held object or separate, thumb-grip held tools. The problems with the earlier known technique are a.o. inferiour accessibility, tool instability, inferior view, impact injury risks and overloading of the hand, and the problems of looking after a complete tool kit. This object is achieved in accordance with the present invention by a handle (1), which at least at one end is equipped with an at least in one plane pivotably arranged driver head socket (2), to which a driver head (3) is attached, said driver head socket being pivotably and lockably arranged in said handle. Exchangeable striking tool bits (10) for different work assignments are easily fitted to said driver head, and extra tool bits are magazined in said handle.

    • PURPOSE: A one-touch type shovel is provided to prevent a shovel plate coupled to a grip from being rotated and to enable the simple maintenance of the shovel plate and the grip. CONSTITUTION: A one-touch type shovel comprises a shovel plate(20) and a grip(10). The shovel plate has a fitting portion(21), a borehole, and a guide groove. The borehole is formed on the bottom surface of the fitting portion. The guide groove is formed from the inner wall surface to the bottom surface of the fitting portion. The grip is inserted into the fitting portion of the shovel plate and coupled to a coupling cap(11). The coupling cap has an engaging protrusion and a sliding protrusion. The engaging protrusion has a latching protrusion. The sliding protrusion is inserted into the guide groove to be slidable.
    • 目的:提供一触式铲子,以防止与手柄相连的铲板旋转,从而能够简单地维护铲板和手柄。 构成:一触式铲子包括铲板(20)和把手(10)。 铲板具有嵌合部(21),钻孔和引导槽。 钻孔形成在嵌合部的底面上。 引导槽由嵌合部的内壁面到底面形成。 把手被插入铲板的装配部分并且联接到联接帽(11)。 联接帽具有接合突起和滑动突起。 接合突起具有闩锁突起。 滑动突起被插入引导槽以可滑动。
