按,習知之一種棘輪扳手結構,請由第13圖所示觀之,該扳手10 於一端係組裝有一棘輪10,且該棘輪11能於扳手101端進行旋轉,藉此扳動螺帽進行鎖緊與旋鬆之作業,又該棘輪10之外緣設置有一齒環11,且該齒環11一側對應齒合有一棘輪12,而該棘輪12能活動於扳手101內部之第一槽室13,又該棘輪12於齒合棘輪10之另一端面形成有一弧面14,另該扳手101於第一槽室13處相通有第二槽室15,由該第二槽室15裝設有一撥紐16,且該撥紐16開設有一插孔17,並於插孔17處裝設有一彈簧18,並於彈簧18頂端套設有一抵套19,使抵套19受彈簧18之頂推而抵觸於棘輪12之弧面14處,藉由撥紐16控制抵套19選擇將棘輪10頂設於第一槽室13之不同側,即能產生有單向驅動之扳動效果。According to a conventional ratchet wrench structure, as shown in FIG. 13, the wrench 10 is assembled with a ratchet 10 at one end, and the ratchet 11 can be rotated at the end of the wrench 101, thereby pulling the nut to lock In the operation of tightening and unscrewing, a toothed ring 11 is disposed on the outer edge of the ratchet 10, and a ratchet 12 is coupled to the corresponding tooth on the side of the ring gear 11, and the ratchet 12 can move to the first slot 13 inside the wrench 101. Further, the ratchet 12 has a curved surface 14 formed on the other end surface of the toothed ratchet 10, and the wrench 101 communicates with the second groove chamber 15 at the first groove chamber 13, and the second groove chamber 15 is provided with a dial. The button 16 is provided with a jack 17 and a spring 18 is mounted on the jack 17, and a sleeve 19 is sleeved on the top end of the spring 18 so that the abutment 19 is pushed against the spring 18 to resist At the arc surface 14 of the ratchet wheel 12, the check sleeve 19 is controlled by the button 16 to select the ratchet wheel 10 to be placed on the different side of the first groove chamber 13, so that the pulling effect of the one-way drive can be generated.
詳觀上述習知結構不難發覺其尚存有些許不足之處,主要原因係 歸如下:(一)、該棘輪件50與撥紐60之間夾設有彈簧62與抵套63,且該抵套63一端受到彈簧62之頂推,而抵套63之另一端滑動抵壓於棘輪件50之弧面51,當棘輪件50於扳手30進行扳動而產生震動或於撥紐60進行切換時,該抵套63一端滑移於棘輪件50之弧面51,且另一端將側向磨擦於撥紐60之插孔61,使抵套63與彈簧62容易由插孔61處彈出或產生變形,並會形成阻力而降低其操作穩定性,且明顯有結構強度不足之問題。It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reasons are as follows: (1) The spring 62 and the abutment 63 are interposed between the ratchet member 50 and the dial 60, and the One end of the abutting sleeve 63 is pushed by the spring 62, and the other end of the abutting sleeve 63 is slid against the curved surface 51 of the ratchet member 50. When the ratchet member 50 is pulled by the wrench 30, vibration is generated or the switch 60 is switched. At the same time, one end of the abutting sleeve 63 slides on the curved surface 51 of the ratchet member 50, and the other end will be laterally rubbed on the insertion hole 61 of the dial 60, so that the abutting sleeve 63 and the spring 62 are easily ejected or generated by the insertion hole 61. Deformation, and will form resistance to reduce its operational stability, and there is a clear problem of insufficient structural strength.
(二)、該扳手30之組裝步驟係先將撥紐60裝設於第二槽室32處,並先進行撥紐60之扣合固定,限制撥紐60僅能進行旋轉操作,再進一步由第一槽室31端將彈簧62置入插孔61內,且於彈簧62頂端套設該抵套63,由於第一槽室31之開口朝向旋轉件40方向,將不易進行安裝彈簧62之動作,又該彈簧62與抵套63之體積較小,容易於組裝過程發生掉落或遺失之情況,更會進一步提高其組裝難度,使其有不易組裝與構件過多之缺失。(2) The assembly step of the wrench 30 is to first install the dial 60 at the second slot chamber 32, and firstly fix and fasten the button 60, and the limit button 60 can only be rotated, and further The end of the first groove chamber 31 places the spring 62 into the insertion hole 61, and the abutment 63 is sleeved on the top end of the spring 62. Since the opening of the first groove chamber 31 faces the rotating member 40, the action of the mounting spring 62 will be difficult. Moreover, the volume of the spring 62 and the abutting sleeve 63 is small, which is easy to be dropped or lost during the assembly process, and the assembly difficulty is further improved, so that it is difficult to assemble and the lack of excessive components.
