Abstract
Description
本發明有關於一種扳手之附加工具，尤其一種可延伸接設於扳手，並驅動扳手之扳手延伸工具。The invention relates to an additional tool for a wrench, in particular to a wrench extension tool which can be extendedly connected to a wrench and drives a wrench.
如美國公開專利號第2005/0183550號所示，其揭露一種扳手輔助工具，其主要藉由柄之兩支撐部，作為支撐扳手，並形成施力支點，在延伸力臂下驅動扳手，可用於特定工作場合，滿足工作者之需求。As shown in US Pat. Pub. No. 2005/0183550, it discloses a wrench auxiliary tool which mainly serves as a support wrench by using two support portions of the handle, and forms a force-supporting point, and drives the wrench under the extension arm, which can be used for Meet the needs of workers in specific workplaces.
惟兩支撐部設置於柄之面板部，並分別自面板部之側邊延伸出，且為相反開口設置，由於柄與面板部為同一平面之延伸，使得兩支撐部直接受力，並無其他結構可輔助支撐，造成結構強度並非絕佳，如兩支撐部長期使用下，有造成疲勞之損壞的可能，另外，兩支撐部之間保持一定距離，使兩支撐部分別至扳手之頭部的距離不同，造成鎖緊、鬆脫螺件之作用力矩不同，如要達成較佳之鎖緊或是鬆脫螺件的效果，扳手輔助工具勢必需要翻轉操作；再者，當其中一支撐部損壞而無法支撐扳手時，扳手輔助工具將只能單向操作，如需換向工作，只能翻轉扳手輔助工具，如此將造成使用上的不便。However, the two support portions are disposed on the panel portion of the handle and extend from the side edges of the panel portion respectively, and are provided for the opposite openings. Since the handle and the panel portion extend in the same plane, the two support portions are directly stressed, and there is no other The structure can assist the support, resulting in structural strength is not excellent, such as the long-term use of the two support parts, there is the possibility of causing fatigue damage, in addition, the two support parts maintain a certain distance, so that the two support parts to the head of the wrench The distance is different, which causes the locking and loosening screws to have different acting moments. In order to achieve better locking or loosening of the screw, the wrench auxiliary tool is bound to need to be turned over; in addition, when one of the supporting parts is damaged When the wrench cannot be supported, the wrench auxiliary tool will only operate in one direction. If the work is to be reversed, the wrench auxiliary tool can only be turned over, which will cause inconvenience in use.
再者，如圖1所示之一種習知扳手輔助工具1，其具有兩支撐部2、3用以接設一扳手4，吾人發現當扳手輔助工具1接設扳手4進行順時針方向驅動工作時，扳手4無法有效被扳手輔助工具1之兩支撐部2、3承接，而無法適用於順時針方向之驅動工作，造成實際上需要翻轉使用的困境。Moreover, as shown in FIG. 1 , a conventional wrench assisting tool 1 has two supporting portions 2 and 3 for connecting a wrench 4 , and it is found that when the wrench auxiliary tool 1 is connected to the wrench 4 for clockwise driving work, When the wrench 4 is not effectively supported by the two supporting portions 2 and 3 of the wrench auxiliary tool 1, it cannot be applied to the driving operation in the clockwise direction, which causes the dilemma that actually needs to be reversed.
為解決上述課題，本發明揭露一種扳手延伸工具，其於頭部設置第一內側面及相對之第二內側面之通道，以接收於一扳手，並且透過第一內側面與第二內側面作為施力之支點，以驅動扳手。In order to solve the above problems, the present invention discloses a wrench extension tool which is provided with a first inner side surface and a second inner side passage passage on a head portion for receiving a wrench and passing through the first inner side surface and the second inner side surface. Apply the fulcrum to drive the wrench.
