Description
本發明是有關一種電動工具結構，且尤其是有關一種具有保護蓋組件的電動工具結構。The present invention relates to a structure of an electric tool, and in particular to a structure of an electric tool with a protective cover assembly.
電動工具為一種方便使用者攜帶的工具，其小體積及輕量化的特性使得許多加工流程不再侷限於固定式的大型加工機底下進行，大幅突破以往加工的地域限制並提升加工靈活性。電動工具內部包含電動馬達以驅動一輸出軸，透過具有轉接裝置的輸出軸端，可搭配不同形式的工具以使電動工具分別應用於鑽孔、切割、拋光研磨等不同場合，因此已被廣泛使用於各領域。The electric tool is a tool that is convenient for users to carry. Its small size and light weight make many processing procedures no longer limited to fixed large-scale processing machines, which greatly breaks through the geographical restrictions of previous processing and enhances processing flexibility. The power tool contains an electric motor to drive an output shaft. Through the output shaft end with an adapter device, it can be matched with different forms of tools so that the power tool can be used in different occasions such as drilling, cutting, polishing and grinding. Therefore, it has been widely used. Used in various fields.
隨著被加工物種類的增加及加工變化性的提升，使用者面對不同加工條件時往往必須更換不同加工模式，例如：面對硬材質時降低轉速以提升扭力；而面對軟性材質時又必須提高轉速以避免被加工物因高溫或靜電沾黏於工具，因而有相關業者開發出具有可改變轉速的電動工具，以適應不同之需求。然而，可改變轉速的電動工具仍然存在其缺點，多數使用者常貪圖一時的便利性而於電動工具運轉途中強行切換轉速，如此容易造成電動工具的零件耗損並降低電動工具原本的使用壽命。With the increase in the types of processed objects and the improvement of processing variability, users often have to change different processing modes when facing different processing conditions. For example, when facing hard materials, reduce the speed to increase the torque; when facing soft materials, they must change different processing modes. The rotation speed must be increased to prevent the workpiece from sticking to the tool due to high temperature or static electricity. Therefore, related industries have developed electric tools with a variable rotation speed to meet different needs. However, power tools that can change the speed still have their shortcomings. Most users often greet the convenience of the moment and forcibly switch the speed during the operation of the power tool. This is likely to cause the parts of the power tool to wear out and reduce the original service life of the power tool.
有鑑於此，如何防止使用者不當操作以避免縮短電動工具的使用壽命，遂成為相關業者努力的目標。In view of this, how to prevent users from improper operation to avoid shortening the service life of electric tools has become the goal of relevant industry efforts.

前述之長槽60的數量可為二，且對稱設置於機身10，而復位彈簧40的數量亦可為二，且分別設置於二長槽60內，藉此使保護蓋本體310受力較平均，並保持於一直線上來回順暢地移動。保護蓋組件30可更包含二凹槽360設置於保護蓋本體310，二凹槽360分別對應二長槽60以共同形成二容置空間(未標示)分別供二復位彈簧40容置，避免復位彈簧40於受壓縮期間產生變形軸向以外的形變而導致保護蓋本體310移動不順暢。The number of the aforementioned
請參照第5圖，其中第5圖繪示第1圖實施例之電動工具結構1的部分示意圖。由第5圖可知，電動工具結構1可更包含四支撐部70，其中二支撐部70分別設置於一長槽60的兩端，另外二支撐部70分別設置於另一長槽60的兩端，支撐部70凸出的外形可配合前述之凹槽360的外形，並偕同前述限制槽50及限制卡勾320的結構配置，使保護蓋本體310能夠更順暢地於第一位置與第二位置之間來回移動。另外，相較於第2圖，第5圖中的保護蓋本體310受外力作用帶動凸出部330壓縮復位彈簧40而位於第二位置，而轉速切換開關20亦位於相對第2圖中的另一位置，此時，操作者透過保護蓋本體310之開口350(示於第4圖)可以直接觀察另一指示部222，藉以明確知道目前電動工具已切換至另一種工作模式。Please refer to FIG. 5, where FIG. 5 is a partial schematic diagram of the
