Description
本發明係有關於一種工具接桿。 The invention relates to a tool post.
車輛保修之手工具如扳手或起子等，或是千斤頂等工具，通常具有固定之長度，因此較難適應各種作業環境，例如欲進行工作之位置較遠，扳手或起子可能過短而無法觸及，或是能夠勉強觸及卻難以施力轉動。 Hand tools for vehicle warranty, such as wrenches or screwdrivers, or tools such as jacks, usually have a fixed length, so it is difficult to adapt to various operating environments. For example, if the position to be worked is far away, the wrench or screwdriver may be too short to be accessible. Or it can barely touch but it is difficult to rotate.
然而，若是延長所有工具之原有長度，不但成本增加，更造成體積龐大、重量過重之困擾，也不利收納，且過長之手工具反倒不利於狹小空間內的短距離工作。 However, if the original length of all tools is extended, not only the cost increases, but also the volume is too large, the weight is too heavy, and it is also unfavorable for storage, and the excessively long hand tools are not conducive to short-distance work in a small space.
因此，市面上便出現一種萬用接桿，可供與手工具連接，使用者便可根據需求選擇性地延長手工具，增加工作距離，且同一接桿能與不同工具配合，節省成本與空間，便於攜帶；為求更為彈性之使用方式，業界更研發了能夠伸縮的接桿，不使用時能縮短收合，更節省空間而更利於攜帶，然而，習知之伸縮接桿之伸縮組件通常強度不足而容易於扭轉作業時受到內外管之間的剪力進而斷裂，且其於收合後之保管及使用亦有其改良之必要。 Therefore, there is a universal pole on the market that can be connected with the hand tool. The user can selectively extend the hand tool according to the demand, increase the working distance, and the same post can be matched with different tools, saving cost and space. It is easy to carry; for more flexible use, the industry has developed a retractable post that can shorten the fit when not in use, and saves space and is more portable. However, the telescopic assembly of the conventional telescopic post is usually If the strength is insufficient, it is easy to be broken by the shear force between the inner and outer tubes during the twisting operation, and it is necessary to improve the storage and use after the folding.

The protruding portion 22 has one end of the fixing portion 222 inserted from the second surface of the elastic piece 21 The opening 211, the fixing portion 222 protruding from the opening 211 is deformed by a tool toward the first surface of the elastic piece 21, and the outer diameter of the fixing portion 222' is larger than the opening. path. In the main embodiment of the present invention, the elastic fastener 2 includes two convex buckles 22, and the elastic springs 21 are provided with two opening holes 211 at opposite ends, and the two convex buckles 22 are respectively disposed on the two opening holes 211. In addition, the convex buckle 22 and the elastic piece 21 are made of metal, and the hardness of the convex buckle 22 is greater than the hardness of the elastic piece 21 and greater than the hardness of the outer tube 11 and the inner tube 12. Therefore, the elastic piece 21 has a relatively high hardness. The small hardness can provide elasticity, and the buckle 22 can withstand the shearing force when the outer tube 11 and the inner tube 12 rotate relative to each other, so that the outer tube 11 and the inner tube 12 can mutually Passing force.
請再參考圖7，該彈釦件2設置於該內管12內且該彈片21之相對兩端抵頂於該內管12之內壁，該凸釦22受該彈片21外推之彈力而穿設於該第二定位孔123中，當滑移該內管12使該第一定位孔113與該第二定位孔123位置相對應時，該凸釦22進一步凸出於該第一定位孔113外而使該內管12與 該外管11無法相對滑動與移動；使用完畢須收合時，僅需以手指自外按壓該凸釦22，使該凸釦22脫離該第一定位孔113而退回該外管11內，該內管12與該外管11便可相對滑動，使用者便能將外管11與內管12收合以利收納。於其他可能實施例中，該外管能進一步開設有多組第一定位孔，該些組第一定位孔沿該外管軸向排列，供使用者選擇其中一組第一定位孔用以定位，於是，該工具接桿之總長度便能輕鬆調整。 Referring to FIG. 7 again, the elastic fastener 2 is disposed in the inner tube 12 and the opposite ends of the elastic piece 21 abut against the inner wall of the inner tube 12, and the convex buckle 22 is elastically pushed by the elastic piece 21 When the inner tube 12 is slid to match the position of the first positioning hole 113 and the second positioning hole 123, the protruding button 22 further protrudes from the first positioning hole. 113 outside the inner tube 12 with The outer tube 11 can not be slid and moved relative to each other; when the user needs to be folded, the button 22 is pressed from the outside by the finger, and the button 22 is separated from the first positioning hole 113 and returned to the outer tube 11 . The inner tube 12 and the outer tube 11 can slide relative to each other, and the user can fold the outer tube 11 and the inner tube 12 for storage. In other possible embodiments, the outer tube can further be provided with a plurality of sets of first positioning holes arranged along the axial direction of the outer tube for the user to select one of the first positioning holes for positioning. Therefore, the total length of the tool post can be easily adjusted.
此外，請參考圖8及圖9，該外管11與該內管12亦可有另一更佳之收合方式。首先先將該內管12完全自該外管11抽離，反以該內管12之第四端自該外管11之第二端***該外管中，並使該第一定位孔113與該第二定位孔123位置相對應，藉此，該凸釦22便能插置於該第一定位孔113與該第二定位孔123中，使該外管11與該內管12無法相對移動及轉動，以達到妥善收合定位之效果，使用者便可輕鬆攜帶而不致使該內管自該外管脫出，並且，收合後之工具接桿仍能以該外管之工作部進行工作，此時，工具接桿之長度較短且具有不同之重心，能配合特定的工作所需，例如千斤頂等需要較重下壓力量之工作。 In addition, referring to FIG. 8 and FIG. 9, the outer tube 11 and the inner tube 12 may have another better folding manner. Firstly, the inner tube 12 is completely pulled away from the outer tube 11, and the fourth end of the inner tube 12 is inserted into the outer tube from the second end of the outer tube 11, and the first positioning hole 113 is The second positioning hole 123 is correspondingly positioned, so that the protruding button 22 can be inserted into the first positioning hole 113 and the second positioning hole 123, so that the outer tube 11 and the inner tube 12 cannot move relative to each other. And rotating to achieve the effect of proper folding and positioning, the user can easily carry without causing the inner tube to escape from the outer tube, and the folded tool post can still be carried out by the working portion of the outer tube At this time, the length of the tool post is short and has a different center of gravity, which can be matched with a specific work requirement, such as a jack, which requires a heavier downforce.
藉由上述結構與使用方式，本發明提供之工具接桿具有良好的耐用度與便利性，更進一步說，本發明提供之工具接桿具有簡單之結構與便利的使用方式，且將內、外管定位之零件具有絕佳之結構強度，避免扭轉作業時受到內、外管間之剪力而 斷裂。 The above-mentioned structure and use manner, the tool post provided by the present invention has good durability and convenience, and further, the tool post provided by the present invention has a simple structure and convenient use manner, and will be internal and external.
