本發明係與一棘輪扳手結構有關,尤指一種棘輪扳手結構中,該轉向組與該制齒之間即具有二處之限制結構,該棘輪扳手碰撞時,該轉向件脫開該第三容槽之機率即大幅降低,該轉向組係具有結構安全性。 The present invention relates to a ratchet wrench structure, and particularly refers to a ratchet wrench structure in which there are two limiting structures between the steering group and the gear. When the ratchet wrench collides, the steering member is disengaged from the third container. The probability of slotting is greatly reduced, and the steering system has structural safety.

按吾人先前所知,習用之棘輪扳手結構,如美國專利案號:2957377,該專利案結構係在於:一本體10,該本體10設有第一容槽13、第二容槽16及第三容槽24;一棘輪14,該棘輪14樞設於該第一容槽13處,該棘輪14外周緣環設有棘輪部15;一制齒19,該制齒19容置於該第二容槽16處,該制齒19一側係設有環狀排列之咬合齒20,該咬合齒20係與該棘輪部15相嚙合,該制齒19另側係設有一凹槽27;一轉向鈕23,該轉向鈕23係樞設於該第三容槽24處,該轉向鈕23設有一限制槽28;一彈性體26,該彈性體26一端係容置於該凹槽27處,該彈性體26另端係容置於該限制槽28處;該本體10、該棘輪14、該制齒19、該轉向鈕23及該彈性體26係為構成該棘輪扳手結構之基本元件,該轉向鈕23於該第三容槽24處旋轉時係帶動該彈性體26一角度轉動,該彈性體26即帶動該制齒19於該第二容槽16處移位,而構成該棘輪扳手結構之正逆轉控制,此亦為該棘輪扳手結構之正逆轉原理。 According to our previous knowledge, the conventional ratchet wrench structure, such as U.S. Patent No. 2957377, consists of a body 10, and the body 10 is provided with a first receiving groove 13, a second receiving groove 16 and a third receiving groove. accommodating groove 24; a ratchet wheel 14, the ratchet wheel 14 is pivoted at the first receiving groove 13, the outer circumference of the ratchet wheel 14 is provided with a ratchet portion 15; a gear tooth 19, the gear gear 19 is accommodated in the second container At the groove 16, one side of the gear 19 is provided with annularly arranged engaging teeth 20. The engaging teeth 20 mesh with the ratchet portion 15. The other side of the gear 19 is provided with a groove 27; a steering button 23. The steering button 23 is pivoted at the third receiving groove 24. The steering button 23 is provided with a limiting groove 28; an elastic body 26. One end of the elastic body 26 is accommodated in the groove 27. The other end of the body 26 is accommodated in the restriction groove 28; the body 10, the ratchet 14, the gear 19, the steering button 23 and the elastic body 26 are the basic components constituting the ratchet wrench structure. The steering button 23 When the third receiving groove 24 rotates, the elastic body 26 is driven to rotate at an angle, and the elastic body 26 drives the gear tooth 19 to be displaced at the second receiving groove 16, thus forming the correct structure of the ratchet wrench. Reversal control, this is also the forward and reverse principle of the ratchet wrench structure.

該彈性體26一端容設於該凹槽27處,該制齒19限制該彈性體26,該彈性體26另端係容置於該限制槽28處,該彈性體26再限制該轉向鈕23,且該轉向鈕23設有一環溝36,設有一環圈37,該環圈37係容設於該環溝36內,該環圈37再卡制於該第三容槽24之內周面上,該轉向鈕23係藉由該彈性體26及該環圈37而樞設於該第三容槽24處,此為該專利案所揭露之結構。 One end of the elastic body 26 is accommodated in the groove 27 , the gear 19 restricts the elastic body 26 , and the other end of the elastic body 26 is accommodated in the restricting groove 28 , and the elastic body 26 restricts the steering button 23 , and the steering button 23 is provided with an annular groove 36 and a ring 37. The ring 37 is disposed in the annular groove 36, and the ring 37 is clamped on the inner peripheral surface of the third groove 24. On the other hand, the steering button 23 is pivoted at the third receiving groove 24 through the elastic body 26 and the ring 37. This is the structure disclosed in the patent case.

但此美國專利案2957377結構之缺失係在於: However, the shortcomings of the structure of U.S. Patent No. 2957377 are:

請輔以公報之圖4所示,該環圈37僅係靠磨擦力而卡制於該第三容槽24之內周面上,如此基本上大都係要靠該制齒19限制該彈性體26以及該彈性體26再限制該轉向鈕23,使該轉向鈕23樞設於該第三容槽24處,但棘輪扳手操作時可能會不慎掉落至地面上,當棘輪扳手碰撞時僅有一處之限制結構係容易使該轉向鈕23脫開該第三容槽24處,而使棘輪扳手無法繼續旋動。 Please refer to Figure 4 of the publication. The ring 37 is clamped on the inner peripheral surface of the third groove 24 only by friction force. Basically, the elastic body is restricted by the teeth 19. 26 and the elastic body 26 further restricts the steering button 23 so that the steering button 23 is pivoted at the third groove 24. However, the ratchet wrench may accidentally fall to the ground during operation. When the ratchet wrench collides, only There is a restriction structure that can easily cause the steering button 23 to disengage from the third groove 24, so that the ratchet wrench cannot continue to rotate.

另一美國專利案號:US6282992B1,請輔以公報之圖1及圖9所示,該專利案之棘輪扳手結構亦設有一本體12、一棘輪72、一制齒40、一轉向鈕50及一彈性體92等基本元件,該專利案在圖9中另揭露有一彈簧帽90,該彈簧帽90係套設於該彈性體92上,該彈簧帽90一端係容設於該凹槽42內,該彈簧帽90另端係容設於該限制槽521內,如此該轉向鈕50係樞設於該第三容槽15內而不脫開,此係為美國專利US6282992B1所揭露之專利結構。 Another U.S. patent case number: US6282992B1, please refer to Figures 1 and 9 of the publication. The ratchet wrench structure of this patent also includes a body 12, a ratchet 72, a gear 40, a steering button 50 and a Basic components such as the elastic body 92.

The other end of the spring cap 90 is disposed in the restricting groove 521, so that the steering button 50 is pivoted in the third receiving groove 15 without being disengaged. This is a patented structure disclosed in US Pat. No. 6,282,992B1.

美國專利US6282992B1係揭露該彈簧帽90,如此藉由該制齒40限制該彈簧帽90,該彈簧帽90再限制該轉向鈕50,當棘輪扳手碰撞時 係僅有一處之限制結構即易使該轉向鈕50脫開該第三容槽15處,使棘輪扳手係無法繼續旋動,專利案號US6282992B1即與專利案號2957377具有相同缺失。 US Patent No. 6282992B1 discloses the spring cap 90, so that the spring cap 90 is restricted by the gear 40, and the spring cap 90 further restricts the steering button 50. When the ratchet wrench collides, The restriction structure at only one point can easily cause the steering button 50 to disengage from the third groove 15, making it impossible for the ratchet wrench to continue rotating. Patent No. US6282992B1 has the same shortcoming as Patent No. 2957377.
