M312399 八、新型說明： 【新型所屬之技術領域】 本新型是有關於一種手工具配件，特別是指一種可供 插接起子頭之手工具之快速接頭。 【先前技術】M312399 VIII. New description: [New technical field] The present invention relates to a hand tool accessory, in particular to a quick connector for a hand tool for inserting a screwdriver. [Prior Art]
如圖1及圖2所示，現有一種快速接頭，是安裝在手 工具上且可針對不同螺絲而換裝不同型式之起子頭5，且起 子頭5具有一沿環向設置的環槽5〇1。該快速接頭具有一與 該手工具連結的本體丨、一裝設在該本體1中的卡掣鋼珠2 、一套設在該本體1外部的環套件3及一抵止在該本體工 與該環套件3之間的彈性元件4。該本體i是製成中空筒狀 並具有呈/、角形的插孔101、一由外部貫穿至該插孔 101的穿孔102及一凸設在一外環面上且位在該穿孔1〇2 一 侧的凸％ 103。該卡掣鋼珠2是可滑動地裝設在該穿孔繼 中。該環套件3是呈中空筒狀且套設在該本體1外部，並 =有-設於内環面且可推掣該卡掣鋼珠2的推拔部3〇ι、一 設置在該推拔冑301 —側的擴徑部302、-介於該推拔部 3〇1與擴徑部302之間且供該凸環1〇3抵止限位的肩部則 及封固在5亥擴控部3〇2侧端部的封環綱。該彈性元件4 疋套設在該凸環103與該封環3〇4之間。 田起子頭5插接在该插孔1〇1中，且該本體工受該彈 1±7〇件4之彈力作用，而帶動該卡掣鋼珠2受該推拔部斯 擎壓時，該卡掣鋼$ 2就可嵌卡在該起子頭5的環槽501 促使（子頭5可疋位在該本體工之插孔ι〇ι中。當推 5 M312399 動該環套件3 (如假想線所示），可使該卡掣鋼珠2對應該 推拔部301較大徑寬處，且具有移動之空間，就可取出起 子頭5。 雖然14種快速接頭可達到預期的使用目的，但是因為 該卡掣鋼珠2與該起子頭5的環槽5〇1是呈點狀接觸（見 圖2 )，以致於卡掣效果並不佳。 【新型内容】 因此，本新型之目的，即在提供一種可使起子頭增加 卡掣面積且提昇定位效果之手工具之快速接頭。 於是，本新型手工具之快速接頭，可供插接起子頭， 且起子頭具有-沿環向設置的環槽，該快速接頭包含一供 起子頭插接的本體、一裝設在該本體中的卡掣件、一套設 在該本體外部的環套件及一彈性元件。該本體具有一圍繞 一轴線且可界定出—六角形插孔的内環面、-與該内環面 相背設置的外環面及一由該外環面貫穿至該内環面的穿孔 。該卡掣件是可滑動地裝設在該穿孔中，並具有一對應該 内環面且可嵌人該起子頭之環槽中的嵌卡端部及—與該嵌 卡端部相反設置且對應該外環面的掣動端部，該嵌卡端部 呈V型，並具有一垂直於該軸線的凸尖部位及二分別銜接 在忒凸大部位上、下側之斜面，該掣動端部呈圓弧狀。該 環套件是㈣在該卡掣件外部，並具有—相對於該外環面 且可推掣該掣動端部的内周面及一由該内周面凹設且對應 該卡擎件的卡溝。該彈性元件是套設在該本體與該環套件 之間，其弹力恆使該環套件之卡溝保持與該卡掣件錯開之 M312399 趨勢。 藉此’利用該嵌卡端部呈v型，當該嵌卡端部嵌入該 環槽中時’可與該起子頭之環槽產生較大接觸面積，且使 該起子頭具有較佳之定位效果。 【實施方式】 有關本新型之前述及其他技術内容、特點與功效，在 以下配合參考圖式之一個較佳實施例的詳細說明中，將可 清楚的呈現。As shown in FIG. 1 and FIG. 2, a conventional quick connector is mounted on a hand tool and can be replaced with different types of screwdriver heads 5 for different screws, and the screwdriver head 5 has a ring groove 5 disposed along the ring direction. 1. The quick connector has a body 连结 coupled to the hand tool, a cassette steel ball 2 mounted in the body 1, a ring set 3 disposed outside the body 1 and a body in the body The elastic element 4 between the ring sets 3. The body i is formed into a hollow cylindrical shape and has a socket 101 in the shape of an or angle, a through hole 102 penetrating from the outside to the insertion hole 101, and a protrusion formed on an outer ring surface and located at the through hole 1〇2 Convex % 103 on one side. The cassette steel ball 2 is slidably mounted in the perforation. The ring set 3 is in the shape of a hollow cylinder and is sleeved on the outside of the body 1 and is provided with a push-out portion 3〇1 which is disposed on the inner ring surface and can push the cassette steel ball 2, and is disposed at the push-out胄 301 — the enlarged diameter portion 302 on the side, the shoulder between the push portion 3 〇 1 and the enlarged diameter portion 302 , and the shoulder portion of the convex ring 1 〇 3 resisting the limit, and the seal is fixed at 5 The sealing ring of the end portion of the control portion 3〇2. The elastic member 4 is sleeved between the convex ring 103 and the sealing ring 3〇4. The head 5 of the field driver is inserted into the jack 1〇1, and the body is subjected to the elastic force of the elastic body 1±7〇4, and when the card steel ball 2 is driven by the push-up portion, the The card 2 steel can be embedded in the ring groove 501 of the screwdriver head 5 (the sub head 5 can be clamped in the jack of the bodywork ι〇ι. When pushing 5 M312399 to move the ring kit 3 (if imaginary As shown by the line, the clicker ball 2 can be made to have a larger diameter and a larger width and a moving space, and the screwdriver head 5 can be taken out. Although 14 kinds of quick connectors can achieve the intended use purpose, Because the cassette steel ball 2 is in point contact with the ring groove 5〇1 of the screwdriver head 5 (see Fig. 2), so that the jamming effect is not good. [New content] Therefore, the purpose of the novel is to The utility model provides a quick connector for a hand tool which can increase the clamping area of the screwdriver head and improve the positioning effect. Thus, the quick connector of the hand tool of the present invention can be used for inserting the screwdriver head, and the screwdriver head has a ring groove arranged along the ring direction. The quick connector includes a body for inserting a screwdriver bit, a latch member mounted in the body, and a set a ring sleeve external to the body and an elastic member. The body has an inner annular surface surrounding an axis and defining a hexagonal receptacle, an outer annular surface disposed opposite the inner annular surface, and a The outer ring surface penetrates through the through hole of the inner ring surface. The latching member is slidably mounted in the through hole, and has a pair of card end portions which should be inner annular surface and can be embedded in the ring groove of the screwdriver head And a swaying end portion opposite to the end portion of the card and corresponding to the outer ring surface, the card end portion is V-shaped, and has a convex portion perpendicular to the axis and two respectively connected to the convex portion a beveled surface of the upper part and the lower side of the large portion, the flap end is arc-shaped. The ring set is (4) outside the latch member and has - relative to the outer ring surface and can push the tilting end An inner circumferential surface and a groove recessed by the inner circumferential surface and corresponding to the carding member. The elastic element is sleeved between the body and the ring sleeve, and the elastic force thereof keeps the groove of the ring assembly maintained The card is staggered by the M312399 trend. By this, the end of the card is v-shaped, and the end of the card is embedded in the ring groove. The time 'can produce a larger contact area with the ring groove of the screwdriver head, and the positioning head has a better positioning effect. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are combined with the following reference drawings. A detailed description of one preferred embodiment will be apparent.
