Abstract
Description
本發明是有關於一種扭力工具。 The invention relates to a torque tool.
一般作業常以套筒用來拆裝機械上的工件(例如螺絲、螺帽等)。然而,習知技術的套筒,其扭力值係固定,而無法根據需求進行調整,導致使用者難以控制力道,而造成拆裝上的不便,且容易損及工件。 In general operations, sleeves are often used to disassemble and assemble mechanical workpieces (such as screws, nuts, etc.). However, the torque value of the sleeve in the prior art is fixed and cannot be adjusted according to the requirement, which makes it difficult for the user to control the force, which causes inconvenience in disassembly and assembly, and easily damages the workpiece.
因此,扭力工具因應而生。習知扭力工具之本體一端設有一驅動頭部,扭力工具之本體內設有一扭力組件藉以控制扭力於一設定值之內,避免損及工件。然而,習知扭力工具之扭力組件僅可提供較有限的扭力控制範圍,拆裝應用範圍較為受限,且扭力組件之彈性件較易斷損。 Therefore, torque tools were born accordingly. One end of the body of the conventional torque tool is provided with a driving head, and a torque component is provided in the body of the torque tool to control the torque within a set value and avoid damage to the workpiece. However, the torsion components of the conventional torsion tools can only provide a relatively limited range of torque control, and the application range of disassembly and assembly is relatively limited, and the elastic parts of the torsion components are more likely to be broken.
因此,有必要提供一種新穎且具有進步性之扭力工具,以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive torque tool to solve the above problems.
本發明之主要目的在於提供一種扭力工具,可避免被驅動件或工件之損壞。 The main purpose of the present invention is to provide a torque tool that can avoid damage to the driven part or the workpiece.
