The first accommodation is in the slot.
按吾人先前所知,習用之棘輪扳手結構,如美國專利案號:US7121170B2,台灣專利案申請號:093200216,證書號:M254305,專利名稱:棘輪扳手之撥位結構,其專利結構係在於:一種棘輪扳手之撥位結構,該棘輪扳手主要係於一柄桿50端部形成有一較大的頭部51,且頭部51內可供容設一工具頭60與一棘塊65,又棘塊65係由一具撥塊70之撥位結構所作動;其特徵在於:該撥位結構之撥塊70形成有一對應棘塊65之貫槽71,再者撥塊70的貫槽71內設有一可供抵頂棘塊65的定位片75,該定位片75後段中央形成有兩上、下對應的切槽76,且於兩切槽76間形成有一導片77,讓定位片75可利用該導片77穿套有一頂撐彈簧78,令定位片75可穩固的頂撐於棘塊65上;藉此組構成一撥動順暢、且定位確實的棘輪扳手之撥位結構者。 As previously known by us, the conventional ratchet wrench structure, such as US Patent No.: US7121170B2, Taiwan Patent Application No.: 093200216, certificate number: M254305, patent name: ratchet wrench dial structure, its patent structure is: The ratcheting wrench is configured to have a larger head 51 at the end of a handle 50, and a head 60 and a ratchet block 65 are accommodated in the head 51, and a ratchet block is provided. The 65 series is driven by a dial structure of the dial block 70; the dial block 70 of the dial structure is formed with a corresponding slot 71 corresponding to the ratchet block 65, and the through slot 71 of the dial block 70 is provided with a slot 71. A positioning piece 75 is provided for the topping block 65. The upper part of the rear piece of the positioning piece 75 is formed with two upper and lower corresponding slots 76, and a guiding piece 77 is formed between the two cutting grooves 76, so that the positioning piece 75 can utilize the positioning piece 75. The guiding piece 77 is sleeved with a supporting spring 78, so that the positioning piece 75 can be stably supported on the ratchet block 65; thereby forming a dial structure with a smooth and well-positioned ratchet wrench.
但此習用棘輪扳手結構之缺失係在於: However, the missing structure of this conventional ratchet wrench is:
1、請輔以公報之第五圖及第六圖所示,該定位片75之總長度通常係小於該撥塊70之外直徑,而很多使用者係會按住撥塊70而轉動工具頭60以測試棘塊65之退齒聲,該定位片75即係可能受該棘塊65擠壓而壓抵該頂撐彈簧78,該定位片75即會完全沒入該撥塊70內,如第十五圖所示,第十五圖係習用棘輪扳手之剖視圖,該定位片75係不會凸伸至棘塊容槽53處,使該定位片75係隨該撥塊70於該撥塊容槽54內可三百六十度轉動,而造成會旋轉過度,該定位片75即會隱於該撥塊容槽54內部,即會切換過度之操作缺失。 1. Please refer to the fifth and sixth figures of the bulletin. The total length of the positioning piece 75 is usually smaller than the outer diameter of the dial 70, and many users will rotate the tool head by pressing the dial 70. 60 to test the topping sound of the ratchet block 65, the positioning piece 75 may be pressed by the ratchet block 65 against the top stay spring 78, and the positioning piece 75 will completely fall into the dial block 70, such as 15 is a cross-sectional view of a conventional ratchet wrench, the positioning piece 75 does not protrude to the spine pocket 53 so that the positioning piece 75 follows the dial 70 to the dial block. The cavity 54 can be rotated by three hundred and sixty degrees, and the rotation of the positioning piece 75 will be hidden inside the dialing pocket 54, that is, the excessive operation is lost.
2、在該第十五圖旋轉過度之狀態下,若該使用者會順時針轉動該撥塊70,該撥塊70及該定位片75即可回位,該棘輪扳手結構仍可繼續使用,但有些使用者即會繼續逆時針轉動該撥動70,當轉動到第十六圖之角度時,第十六圖係習用棘輪扳手之剖視圖,該棘塊65和該棘塊容槽53間係有間隙,該定位片75即受頂撐彈簧78之彈力而彈至此間隙處,該棘塊65和該定位片75即同時容設於該棘塊容槽53內,該棘輪扳手結構即無法再繼續使用。 2. In the state in which the fifteenth figure is excessively rotated, if the user rotates the dial 70 clockwise, the dial 70 and the positioning piece 75 can be returned, and the ratchet wrench structure can still be used. However, some users will continue to rotate the toggle 70 counterclockwise. When turning to the angle of the sixteenth figure, the sixteenth diagram is a cross-sectional view of the conventional ratchet wrench, and the ratchet block 65 and the spine pocket 53 are When there is a gap, the positioning piece 75 is elastically attracted to the gap by the elastic force of the top spring 78, and the ratchet block 65 and the positioning piece 75 are simultaneously accommodated in the spine pocket 53, and the ratchet wrench structure can no longer be continue to use.
另一習用之棘輪扳手結構,此係為申請人所申請之專利前案,台灣專利申請號:101102061,證書號I409144,專利名稱:棘輪扳手結構,請輔以公報之第一圖所示,該專利案具有可避免切換過度之缺失,但該轉向件41需有該第一扣環44扣設,如此該本體10即要加工該第一扣環槽131,該第三容槽13之直徑一般不可能太大,若為二分之該本體10,該第三容槽13之直徑可能為6MM,於該6MM之直徑之該第三容槽13內加工該第一 扣環槽131係較費工且加工,且該第一扣環槽131之刀具係又非常小而造成另一缺失。 Another conventional ratchet wrench structure, which is the patent application filed by the applicant, Taiwan Patent Application No.: 101102061, certificate number I409144, patent name: ratchet wrench structure, please be accompanied by the first figure of the bulletin, The patent case has the disadvantage of avoiding over-switching, but the steering member 41 needs to be fastened by the first buckle 44, so that the body 10 is to process the first buckle groove 131, and the diameter of the third cavity 13 is generally It may not be too large. If the body 10 is two-pointed, the diameter of the third pocket 13 may be 6 mm, and the first pocket is processed in the third pocket 13 of the diameter of 6 mm. The buckle groove 131 is relatively labor-intensive and processed, and the cutter system of the first buckle groove 131 is very small and causes another defect.

In addition, as shown in FIG. 12, the positioning member 50 restricts the steering member 41 from rotating only between the two positioning portions 414, so that the steering member 41 cannot be rotated by three hundred and sixty degrees. The steering member 41 is unlikely to have a lack of over-switching.
4、該定位件50係抵於該轉向件41之其一定位部414處,該珠體44係受該彈性元件43之彈力而靠抵於該定位件50周面處,使該轉向組40即具定位一位置,當手撥動該轉向件41使其於該第三容槽13內轉動時,該定位件50係頂壓該珠體44,使該珠體44係內縮至該第二容置槽413內,該珠體44並壓縮該彈性元件42,使該定位件50係抵於另一定位部414處,該珠體44係再靠抵於該定位件50周面處,使該轉向組40轉動後而定位於該第三容槽13內另一位置。 4. The positioning member 50 is abutting against a positioning portion 414 of the steering member 41. The bead body 44 is biased against the circumferential surface of the positioning member 50 by the elastic force of the elastic member 43 to make the steering group 40. That is, when the steering member 41 is rotated by the hand to rotate the third housing 13 , the positioning member 50 presses the bead 44 to retract the bead 44 to the first portion. In the second receiving groove 413, the bead body 44 compresses the elastic member 42 to fasten the positioning member 50 to the other positioning portion 414. The bead body 44 is further abutted against the circumferential surface of the positioning member 50. The steering group 40 is rotated to be positioned at another position in the third pocket 13.
5、當手撥動該轉向件41使其轉動時,該定位件50係受該第一直徑18及該第二直徑417間之偏心距離作用,該定位件50係可將該轉向件41之該圓柱塊411向前推移靠向該本體10之該第二容槽12及該第三容槽13之相交處,亦即該轉向件41與該第三容槽13間係略不呈樞設狀,使該定位件50通過該頂面415而抵於另一定位部414處,該圓柱塊411係受該彈性元件43之彈力頂抵而再樞設於該第三容槽13處,該定位件50係容設於該定位部414處而定位該轉向組40。 5. When the steering member 41 is rotated by the hand, the positioning member 50 is subjected to an eccentric distance between the first diameter 18 and the second diameter 417, and the positioning member 50 can be used for the steering member 41. The cylindrical block 411 is forwardly moved to the intersection of the second receiving slot 12 and the third receiving slot 13 of the body 10, that is, the steering member 41 and the third receiving slot 13 are not pivoted. The locating member 50 is passed through the top surface 415 to the other positioning portion 414. The cylindrical block 411 is pivoted by the elastic member 43 and is pivotally disposed at the third receiving slot 13. The positioning member 50 is received at the positioning portion 414 to position the steering group 40.
