Description
本創作係與一種棘輪扳手有關，特別是指一種棘輪扳手之驅動頭結構改良者。This creation is related to a ratchet wrench, and in particular to a driver of a ratchet wrench.
按，一般機械廠、汽車修護廠等工作場所，經常會於施工時使用各式種類的扳手，例如：梅花板手、套筒扳手、開口扳手、活動扳手及棘輪扳手等手工具，用以拆裝螺栓幫助完成維修或組裝之工作，因棘輪扳手具有單向作動之功能，而帶給使用者於施工時有相當大之方便性。Press, general machinery factory, automobile repair factory and other workplaces, often use various types of wrenches during construction, such as: plum wrench, socket wrench, open end wrench, adjustable wrench and ratchet wrench, etc. The disassembly and assembly bolts help to complete the repair or assembly work. Because the ratchet wrench has the function of one-way operation, it brings considerable convenience to the user during construction.
而坊間一般之棘輪扳手，請參閱公告號第M316777號之「棘輪扳手結構改良」，請參閱第1圖所示，第1圖係習用之D頭結構立體放大圖，其中限位該棘輪扳手之D頭1結構，主要係以一螺帽3鎖固於該D頭1頂端面之螺栓4上，同時該螺帽3將該轉動盤2限位於該螺帽3與該D頭1之間。For the general ratchet wrench, please refer to the "Improvement of Ratchet Wrench Structure" in Bulletin No. M316777. Please refer to Figure 1 for a detailed enlarged view of the D-head structure used in the first example, which limits the ratchet wrench. The structure of the D head 1 is mainly locked by a nut 3 to the bolt 4 on the top end surface of the D head 1 , and the nut 3 limits the rotating disc 2 between the nut 3 and the D head 1 .
由上述公告第M316777號之「棘輪扳手結構改良」之專利前案係利用該螺帽3與該螺栓4之螺紋結構設計以作為棘輪扳手其主要用以鎖緊轉動盤2與扳手它部構件結合之固接結構；其中螺紋結構不僅加工製造上較費工，在組裝時須費時費力將相互配合之內外螺紋鎖固，且因鎖固時施力過大，使轉動盤2與D頭1餘隙過小，易造成轉動盤不易轉動調整，又，當使用一段時間後，相互配合之螺紋亦會因使用或攜帶時之震動等因素，而發生鬆脫之情形。The patent application of the "ratchet wrench structure improvement" of the above-mentioned publication No. M316777 utilizes the threaded structure of the nut 3 and the bolt 4 as a ratchet wrench, which is mainly used for locking the rotating disk 2 and the wrench member. The fixing structure is not only labor-consuming in manufacturing, but also requires time and effort to lock the internal and external threads which are matched with each other during assembly, and the force is too large when locking, so that the rotating disk 2 and the D head 1 clearance Too small, it is easy to cause the rotating disc to be difficult to rotate and adjust. Moreover, when used for a period of time, the mating threads may also be loosened due to factors such as vibration during use or carrying.
有鑑與此，本創作者針對現有棘輪扳手的缺失，以及所面臨之問題深入研究，並針對棘輪扳手作更新之研發及改善習式之缺弊，此 即為本創作之設計宗旨。In view of this, the creator has in-depth research on the lack of existing ratchet wrenches and the problems faced, and has developed and improved the drawbacks of the ratchet wrench. This is the design tenet of this creation.
