現有的棘輪扳手結構，如證書號數M395549、M399781 、1340066等專利案，都是在一工具本體内部安.裝一具有數 個棘齒之棘輪及至少一掣爪塊，利用該掣爪塊所設的卡齒 與该棘輪的棘齒咬合，以及該掣爪塊的換向操作，即可達 到正向聯動、反向空轉以及可換向聯動之目的。 上述的棘輪扳手結構雖然相當普遍可見，但實際上仍 有下列問題： 一、該棘輪的棘齒數量愈少，作動角度就愈大，操作 速度慢、操作空間的限制也愈大。 一、該棘輪的棘齒數量若增加，則因齒深小，則咬合The existing ratchet wrench structure, such as the certificate numbers M395549, M399781, 1340066, etc., is mounted inside a tool body with a ratchet ratchet and at least one pawl block. The card teeth are engaged with the ratchet of the ratchet, and the reversing operation of the claw block can achieve the purpose of forward linkage, reverse idling and reversible linkage. Although the above-mentioned ratchet wrench structure is quite common, it still has the following problems: 1. The fewer the ratchet teeth of the ratchet, the larger the actuation angle, the slower the operation speed and the greater the limitation of the operation space. 1. If the number of ratchets of the ratchet increases, the bite is small, and the bite is occluded.
力較不足，扭力過載時容易造成崩齒，且容易造成操作： 受傷及物的破壞。 二、反·>空冑之f爪塊在該棘輪的棘齒上產生跳脫 ，會發出健噠的噪音。 另外亦有另種無齒式棘輪扳手（例如證書號數 M246U1、M2433G2等專利案），是在-工具本體與-_桿 之間形成數個具有深、淺端的滑動空間，且在該等滑動* 間中均設有-個m滚柱與該卫具本體—内環面、該 驅動桿一受掣面所形成的-失角若較小，則操作時較容易 造成打滑，且該工具本體之内環面與該驅動桿之受擎面之 ㈣最大深度與各滚柱之外徑的比值若愈大.，則作動角声 就愈大，操作速度慢'操作空間的限制也較大，該等專^ 案分別具有上述的問題，實有待改善。 【新型内容】 因此，本新型之目的，即在提供一種操作時可防止打 滑且操作速度快、操作空間限制小的棘輪扳手。 於是’本新型的棘輪扳手包含一本體、一驅動件 個卡料及一切換單元。該本體具有一頭部及—連牡在节 頭部-側的握柄，該頭部具有一圍繞—軸線且可界定―： 孔的内環面，該驅動件安襄在該内孔中，並具有—驅動段 、一沿該軸線設於該驅動段一侧的出力段、一沿該轴線约 於該驅動段另-側的延伸段及—銜接在該驅動段與ς 段之間的端面，該驅動段具有數個對應該内環面的受掣面 ’該等受掣面與該内環面之間各形成一滚動空間’該等滚 動空間各具有—深部及分別位於該深部兩側的—第—淺部、 間 其中，通過每一卡掣件之圓心與該第—端緣的 第二弟二淺部’該深部具有一最大深度，且由該深部朝該 第、—淺部延伸時之深度逐漸縮小，料卡掣件分別套 設在該等滾動空間中，並各具有一内切於該内環面的第一 端緣及-卡擎在所對應之受掌面的第二端緣’該切換單元 ’：使該等卡掣件在-第-位置與-第二位置之間切換， 該等卡掣件在第一&置時是位於該深部與該第一淺部之門 ，該等卡掣件在第二位置時是位於該深部與該第二二部二 4 ττ ««9 M422452 本2… 與通過該卡掣件之圓心與該第：端緣的__基準線1^ 夾角，大於⑽。且小於180。，各滾動空間之深部的深产 與母一卡掣件的外徑比值大於1且小於M。 本新型之功效：利用該法線與該基準線之間的炎角大 於160。且小於18〇。之作用，在操作時可防止該等卡擎件 打滑，且利用各滚動空間之深部的深度與每一卡擎件的外 徑比值大於1且小於U之作用，則操作速度快、操作空間 限制小，且無崩齒的危險。Insufficient force, it is easy to cause disintegration when the torque is overloaded, and it is easy to cause operation: injury and damage. Second, the anti-> empty c-claws will trip on the ratchet of the ratchet, which will produce a healthy noise. In addition, there are also other non-toothed ratchet wrenches (such as the certificate number M246U1, M2433G2 and other patents), which are formed between the tool body and the -_ rod with a plurality of sliding spaces having deep and shallow ends, and sliding in the same * There is a - m roller in between and the body of the guard - the inner ring surface, the drive rod is formed by the squat surface - if the angle of loss is small, the operation is more likely to cause slippage, and the tool body The greater the ratio of the inner surface of the inner ring surface to the outer surface of the drive rod and the outer diameter of each roller, the larger the angle of the active angle and the slower the operation speed. These special issues have the above problems and need to be improved. [New content] Therefore, the object of the present invention is to provide a ratchet wrench that can prevent slipping and has a high operating speed and a small operating space limitation. Thus, the ratchet wrench of the present invention comprises a body, a driving member, and a switching unit. The body has a head and a grip on the head-side of the joint, the head having an inner annular surface surrounding the axis and defining a ": hole", the driving member is mounted in the inner hole, And having a driving section, an output section disposed on one side of the driving section along the axis, an extension extending along the axis on the other side of the driving section, and engaging between the driving section and the winding section An end surface, the driving segment has a plurality of receiving surfaces corresponding to the inner annular surface, and a rolling space is formed between the receiving surface and the inner annular surface. The rolling spaces each have a deep portion and are respectively located - the shallow part of the deep side, wherein the depth of the center of each of the jaws and the second portion of the first edge of the first edge have a maximum depth, and the deep portion faces the first - the depth of the shallow portion is gradually reduced, the material snaps are respectively sleeved in the rolling spaces, and each has a first end edge inscribed in the inner annular surface and - the card is in the corresponding palm The second end edge of the face 'the switching unit': switches the card members between the -first position and the second position, The first clamping member is located at the front portion of the first portion and the first shallow portion, and the latching members are located at the deep portion and the second portion of the second portion 2 ττ ««9 M422452 This is the angle between the center of the card and the __reference line 1^ of the first: edge, which is greater than (10). And less than 180. The deep production of the deep part of each rolling space is larger than the outer diameter ratio of the parent-card element by more than 1 and less than M. The efficacy of the novel: the angle between the normal and the baseline is greater than 160. And less than 18 inches. The operation can prevent the card slicks from slipping during operation, and the operation speed is fast and the operation space is fast by using the depth of the deep portion of each rolling space and the outer diameter ratio of each card rushing member to be greater than 1 and less than U. The restriction is small and there is no danger of chipping.
