Abstract

The present invention is an angle adjustable power tool comprising a handle, an actuator, and a positioning assembly. The handle is equipped with an engaging base and an engaging plate. The engaging base is located at the top of the handle and faces the actuator, and has a communicating slot and a fixed slot. The engaging plate is positioned inside the fixed slot of the engaging base. The actuator is rotatably coupled to the handle and is provided with a pivot base and a head portion. The pivot base is located at the bottom of the actuator and is rotatably coupled with the handle to allow the engaging base and engaging plate to be positioned between the handle and the pivot base. The positioning assembly is located between the handle and the actuator and is provided with a positioning base, an elastic member, an abutment base, and a turning member, thus providing a structurally simplified, accurately positioned, and cost-saving angle adjustable power tool. When the turning member rotates relative to the abutment base, it causes the positioning base to separate from the engaging base and compresses the elastic member. Through the relative rotation of the pivot base with respect to the handle, the angle of the actuator relative to the handle can be adjusted, and after adjustment, the compressed elastic member causes the positioning base to move towards the engaging plate and engage therewith for positioning.

Description

可調整角度的動力工具Angle-adjustable power tool

本發明涉及一種動力工具，尤指一種結構精簡、準確定位且節省成本的可調整角度之動力工具。The present invention relates to a power tool, in particular to a power tool with a simple structure, accurate positioning and cost-saving and adjustable angle.

現有動力工具可透過電力或氣體進行驅動，藉以對於工件進行加工，現有動力工具設有一握柄及一與該握柄相結合的作動頭，當使用者握持該握柄並透過該作動頭對於工件進行加工時，假若使用者與該工件的相對位置無法經由該作動頭進行加工時，相對會增加使用上的不便，因此，目前會於現有動力工具的該握柄及該作動頭之間設置一樞接裝置，透過該樞接裝置調整該作動頭相對該握柄的角度，讓使用者以適當的角度對於工件進行加工。Existing power tools can be driven by electricity or gas to process workpieces. Existing power tools are provided with a handle and an actuator head combined with the handle. When a user holds the handle and processes the workpiece through the actuator head, if the relative position of the user and the workpiece cannot be processed through the actuator head, it will increase the inconvenience of use. Therefore, a hinge device is currently provided between the handle and the actuator head of the existing power tool. The angle of the actuator head relative to the handle is adjusted through the hinge device, so that the user can process the workpiece at an appropriate angle.

然而，現有動力工具雖可透過設置該樞接裝置的方式，調整該作動頭與握柄之間的角度，達到方便使用的效果，但位於該作動頭及該握柄之間的樞接裝置缺少可穩固定位的結構，使經過角度調整後的該作動頭在加工的過程中可能會相對該握柄擺動，容易造成工件的損傷以及發生危害工安的情況，進一步，現有動力工具若以氣體進行驅動時，為了準確地讓氣體經由該握柄及該樞接裝置而傳送至該作動頭，現有動力工具必須在該握柄、樞接裝置及該作動頭之間設置形狀複雜且不易加工的氣體流道，相對增加製造所需之成本及時間，綜上所述，現有動力工具實有其需加以改進之處。However, although existing power tools can adjust the angle between the actuator head and the handle by providing the pivot device to achieve convenient use, there is a lack of a pivot device between the actuator head and the handle. Due to the stable positioning structure, the actuator head after angle adjustment may swing relative to the handle during processing, which may easily cause damage to the workpiece and endanger work safety. Furthermore, if existing power tools use gas for processing During driving, in order to accurately transmit gas to the actuator head through the handle and the pivot device, existing power tools must install a complex-shaped and difficult-to-process gas between the handle, the pivot device and the actuator head. The flow channel relatively increases the cost and time required for manufacturing. In summary, existing power tools do have areas that need to be improved.
