    • A pneumatic hammer drill includes a handle body, a pneumatic cylinder, a piston, and a shock-absorbing sleeve. The pneumatic cylinder has a cylinder rear end fitted in the handle body, a front tool-connecting end, and a pressure chamber. The piston is disposed slidably in the pressure chamber. A tool is inserted into the pressure chamber through the front tool-connecting end. A spring element is attached to the front tool-connecting end, and has a spring end connected to the tool for pulling the same rearwardly. The shock-absorbing sleeve is made of a resilient material, is inserted into the front tool-connecting end around the tool, and has a front end to abut against the tool when the tool is pulled rearwardly.
    • 一种气动锤钻包括手柄本体,气动缸,活塞和减震套。 气缸具有安装在把手主体中的气缸后端,前工具连接端和压力室。 活塞可滑动地设置在压力室中。 工具通过前工具连接端插入压力室。 弹簧元件连接到前工具连接端,并且具有连接到工具的弹簧端,用于将其向后拉。 减震套筒由弹性材料制成,在工具的前部工具连接端插入,当工具被向后拉时,其前端与工具抵接。

    • A mounting base of a telescope is assembled between a focusing device and a tubular body and is assembled on a tripod. The mounting base has a sleeve portion and a base portion. The sleeve portion has a rear end and a front end for being assembled with a front end of the focusing device and a rear end of the tubular body, respectively. The base portion integrally connects with a bottom of an outer annular surface of the sleeve portion. The base portion is for being assembled on the tripod. As a result, the mounting base of a telescope of the present invention integrates a sleeve's function and a base's function together. Therefore, the cost of the telescope is reduced, and the stability and the appearance of the telescope are improved.
    • 望远镜的安装基座组装在聚焦装置和管状体之间,并组装在三脚架上。 安装基座具有套筒部分和基部部分。 套筒部分具有分别与聚焦装置的前端和管状体的后端组装的后端和前端。 基部与套筒部分的外环形表面的底部整体连接。 基座部分用于组装在三脚架上。 结果,本发明的望远镜的安装基座将套筒的功能和底座的功能集成在一起。 因此,望远镜的成本降低,望远镜的稳定性和外观得到改善。

    • The present invention discloses a quadri-filar helix antenna structure, which comprises a cylindrical body made of a dielectric material with a relative dielectric constant ∈r greater than 4, and four radiating metal plates disposed on a distal end surface of the cylindrical body and extended along the radial direction of the center of the cylindrical body to its periphery and then along the radial direction in a spiral course on the circumferential surface thereof to its periphery on the other end respectively, wherein the ends of every two adjacent radiating metal plates are coupled with each other to constitute two sets of antenna structures, a penetrating hole is disposed at the central position of the cylindrical body and is precisely embedded into a coaxial cable, and a shield cable disposed at the periphery on one end of the coaxial cable is coupled to an end of another set of antenna structure. Therefore, the antenna not only reduces the overall volume, but also greatly lowers its production costs.
    • 本发明公开了一种四线螺旋天线结构,其包括由相对介电常数εζ大于4的电介质材料制成的圆柱体,以及设置在远端上的四个辐射金属板 圆柱体的表面并沿着圆柱体的中心的径向方向延伸到其周边,然后沿其径向方向在其圆周表面上以螺旋状的方式延伸到另一端的周边,其中每个 两个相邻的辐射金属板彼此耦合以构成两组天线结构,在圆柱体的中心位置设置一个穿透孔,并且精确地嵌入到同轴电缆中,并且屏蔽电缆设置在一个外围的一个 同轴电缆的端部耦合到另一组天线结构的一端。 因此,天线不仅可以降低总体积,而且大大降低了其生产成本。
