Description

棘輪扳手Ratchet wrench

本創作係有關於一種棘輪扳手，特別是指一種具伸縮以及可直立操作之棘輪扳手。This creation is related to a ratchet wrench, especially a ratchet wrench that can be extended and operated upright.

按，棘輪扳手是一種相當常見的手工具，一般係用來擰鬆、旋緊螺絲、螺帽等，通常該習知棘輪扳手係具有一握柄，且該握柄之一端係形成有一頭部，該頭部之一側係凹設有一容槽，該容槽內係容置有一棘輪，使該棘輪可於容槽內轉動，此外該容槽內更容置有至少一棘爪，該棘爪係連接有一換向桿，可供操作該棘爪選擇性抵頂於該棘輪，以控制該棘輪之離合與轉動方向。Press, the ratchet wrench is a very common hand tool, generally used to loosen and tighten screws, nuts, etc. Usually the conventional ratchet wrench has a handle, and one end of the handle is formed with a head , One side of the head is concavely provided with a pocket, and a ratchet wheel is accommodated in the pocket so that the ratchet wheel can rotate in the pocket. In addition, at least one pawl is accommodated in the pocket. The pawl is connected with a reversing rod for operating the pawl to selectively abut against the ratchet to control the direction of clutch and rotation of the ratchet.

然而，該習知棘輪扳手之握柄長度係為固定的，於實際使用上，常會遇到因長度過長不便操作，或是因長度過短無法操作等許多使用環境上的限制，而無法適用於各種使用環境，且固定長度的設計也不便攜帶，另一方面，該習知棘輪扳手係以橫向進行操作，在使用上亦受到許多限制，是以，本案創作人在觀察到上述缺點後，認為現有的棘輪扳手實有改進之必要，而遂有本創作之產生。However, the length of the handle of the conventional ratchet wrench is fixed. In actual use, it is often inconvenient to operate because the length is too long, or because the length is too short to operate, and many other restrictions on the use environment, which cannot be applied. In various use environments, and the fixed-length design is not portable. On the other hand, the conventional ratchet wrench is operated horizontally, which is also subject to many restrictions in use. Therefore, the creator of this case, after observing the above shortcomings, It is believed that there is a need for improvement of the existing ratchet wrench, and this creation was born.

本創作之目的係在提供一種棘輪扳手，其係可伸縮進行長度調整，並能結合各式各樣的驅動件，而具有多功能性。The purpose of this creation is to provide a ratchet wrench, which can be telescopic for length adjustment, and can be combined with various driving parts, and has versatility.
