【物品用途】;本設計係關於一種工具扳手，尤其是一種設有固定式或棘輪式的起子頭套接座，而可用以插設起子頭而藉以轉動螺絲，或直接以套接座套接元件後進行轉動的工具扳手。;【設計說明】;本設計之特點在於本設計具有一圓筒形的握把結構，圓筒形握把的上下端分別係具圓弧倒角的端緣。該握把上端凸設有一樞轉台，該樞轉台由前視圖觀之，形狀似一「凹」字形，凹字頂緣呈現由前至後的圓弧狀(參見立體圖)；由側視圖觀之，該樞轉台由上往下呈現寬度漸寬之內凹弧形。此外，該樞轉台上樞接有一套接部，該套接部包括一近似拇指形的承接塊，該承接塊上則於前後二表面凸設有供起子頭插設的套接座，該套接座外徑呈圓筒形，而內徑則為多邊形柱狀凹槽，該凹槽形狀可為四邊形、五邊形或六邊形，但並不以此為限。本設計的圓筒形握把及其圓弧倒角端緣，呈現高雅洗鍊的線條，加上樞轉台的弧面與曲線造型，係完全異於習知之扁平把手或是常見之六角握把構型，具有獨特創新的視覺印象。;圖式所揭露之虛線部分(六邊形柱狀凹槽)，係表示可應用於各種多邊形柱狀凹槽，為本案不主張設計之部分。;請參見使用狀態圖以及使用狀態參考圖，本設計可依需求於套接座插設不同的起子頭。使用時，則可將套接部於樞轉台上樞轉以調整角度，而方便於不同使用空間的操作。[Use of article]; This design relates to a tool wrench, especially a screwdriver bit socket with a fixed or ratchet type, which can be used to insert the screwdriver bit to turn the screw, or directly use the socket to connect components Tool wrench for later turning. ;[Design Description];The characteristic of this design is that it has a cylindrical grip structure, and the upper and lower ends of the cylindrical grip are respectively equipped with arc-chamfered end edges. The upper end of the handle is convexly provided with a pivoting platform. The pivoting platform is shaped like a "concave" when viewed from the front view, and the top edge of the concave character is arc-shaped from front to back (see the perspective view); when viewed from the side view , the pivot table presents a concave arc shape with gradually widening width from top to bottom. In addition, a socket part is pivotally connected to the pivot table. The socket part includes a thumb-shaped receiving block. The receiving block is protruding from the front and rear surfaces with socket seats for the screwdriver head to be inserted. The socket is The outer diameter of the socket is cylindrical, while the inner diameter is a polygonal columnar groove. The shape of the groove can be quadrilateral, pentagonal or hexagonal, but is not limited to this. The cylindrical handle of this design and its arc-chamfered end edge present an elegant chain-washing line. Together with the arc surface and curved shape of the pivot table, it is completely different from the conventional flat handle or the common hexagonal handle. configuration, with a unique and innovative visual impression. ; The dotted line part (hexagonal columnar groove) disclosed in the drawing indicates that it can be applied to various polygonal columnar grooves, and is a part of the design that is not recommended in this case. ; Please refer to the usage status diagram and usage status reference diagram. This design can be equipped with different screwdriver bits in the socket according to needs. When in use, the socket part can be pivoted on the pivoting table to adjust the angle, which facilitates operation in different use spaces.
