Description

Torque Tool

本發明是有關於一種扭力工具。The present 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 workpieces on machinery (such as screws, nuts, etc.). However, in the conventional sleeve, the torque value is fixed and cannot be adjusted according to requirements, 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。Therefore, torque tools were born accordingly. One end of the body of the conventional torque tool is provided with a driving head, and the body of the torque tool is provided with a torque component to control the torque within a set value to avoid damage to the workpiece. However, the torque component of the conventional torque tool can only provide a relatively limited torque control range, and the application range of disassembly and assembly is relatively limited.

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.
