In the reverse steering, the ratchet unit 40 is coupled to the eccentric shaft portion 352 of the anvil shaft 35, and the rotation of the eccentric shaft 3521 is used to drive the ratchet unit 40 to actuate the bolt or nut quickly and automatically. Since the ratchet unit 40 is of the prior art, the detailed operation and the manner of use are not described herein.

本發明之較佳實施例的使用方式係如圖1、圖 4及圖5所示,使用者係可握持該握柄10並按壓該壓鈕12,以驅動該驅動馬達11作動,使該驅動馬達11能夠帶動該旋轉座32旋轉,由於該擊盤33係以該樞軸部311連接於該旋轉套筒31,並以該卡制凸部333連接該旋轉座32,當該驅動馬達11呈正轉的狀態,當該驅動馬達11正轉作動也帶動該旋轉座32旋轉,同時一併帶動該旋轉套筒31與該擊盤33共同旋轉,而該擊盤33在轉動過程中將會以該樞軸部311為軸心偏擺,並以其中一側的該擊打部332沿著轉動方向撞擊相對應的該抵靠緣3511,並藉此產生扭力並帶動該棘輪單元40作動,當該棘輪單元40之工具頭42的扭力大於該衝擊組30所產生的扭力時,則該擊盤33在偏擺過程中所造成的扭力不足以推動該擊砧軸35,於是該擊盤33在產生偏擺的過程中就會滑開而不再推動該擊砧軸35,如此一來,可避免該擊盤33不斷敲擊該擊砧軸35而造成被鎖物鎖死狀態。 The manner of use of the preferred embodiment of the present invention is as shown in FIG. 1 4 and FIG. 5, the user can hold the handle 10 and press the push button 12 to drive the drive motor 11 to operate, so that the drive motor 11 can drive the rotary seat 32 to rotate, because the striker 33 The pivot portion 311 is connected to the rotating sleeve 31, and the rotating seat 32 is connected by the locking protrusion 333. When the driving motor 11 is in a forward rotation state, the driving motor 11 is driven to rotate forward. The rotating base 32 rotates, and simultaneously rotates the rotating sleeve 31 together with the striking disc 33, and the striking disc 33 will be deflected with the pivot portion 311 as an axis during the rotation, and one side thereof The striking portion 332 strikes the corresponding abutting edge 3511 along the rotational direction, and thereby generates a torsion force and drives the ratchet unit 40 to act. When the torque of the tool head 42 of the ratchet unit 40 is greater than the impact group 30 When the generated torque is applied, the torsion force caused by the striker 33 during the yaw is insufficient to push the anvil shaft 35, so that the striker 33 slides away during the yaw generation and no longer pushes the strike. The anvil shaft 35, in this way, the striking disc 33 can be prevented from continuously hitting the anvil shaft 35 to cause the lock Locked state.

如此一來,本發明之衝擊組30係利用該擊盤33撞擊擊砧軸35來帶動該棘輪單元40作動,由於該擊盤33的形狀簡單易於加工,能夠達到降低生產成本的目的,且組裝方式簡易,當該擊盤33損壞時,也容易拆卸置換。 In this way, the impact group 30 of the present invention uses the striking disc 33 to strike the anvil shaft 35 to drive the ratchet unit 40 to operate. Since the shape of the striking disc 33 is simple and easy to process, the production cost can be reduced and assembled. The method is simple, and when the striking disc 33 is damaged, it is also easy to disassemble and replace.

如圖6及圖7所示,本發明的第二較佳實施例與第一較佳實施例大致相同,差異在於:該衝擊組30A之擊砧軸35A係為可拆式,其中,該擊砧軸35A係包括有一擊砧部351A、一偏心軸部352A及一結合套筒353,該擊砧部351A的一端設有前述 的抵靠緣3511,並於該抵靠緣3511的相反端形成一多角形的第一組裝面3512,該偏心軸部352A的一端設有前述的偏心軸3521,於該偏心軸3521的相反端形成與該擊砧部351A相對應的第二組裝面3522,該結合套筒353係分別於兩端形成多角形的組裝槽3531,並分別以該兩組裝槽3531對應結合於該第一組裝面3512與該第二組裝面3522,使該擊砧軸35A形成可拆卸的狀態。 As shown in FIG. 6 and FIG. 7, the second preferred embodiment of the present invention is substantially the same as the first preferred embodiment. The difference is that the anvil axis 35A of the impact group 30A is detachable, wherein the impact is The anvil shaft 35A includes an anvil portion 351A, an eccentric shaft portion 352A and a coupling sleeve 353. One end of the anvil portion 351A is provided with the foregoing Abutting edge 3511, and forming a polygonal first assembly surface 3512 at the opposite end of the abutting edge 3511, one end of the eccentric shaft portion 352A is provided with the aforementioned eccentric shaft 3521, and the opposite end of the eccentric shaft 3521. A second assembly surface 3522 corresponding to the anvil portion 351A is formed. The coupling sleeve 353 is formed with a polygonal assembly groove 3531 at both ends, and is respectively coupled to the first assembly surface by the two assembly grooves 3531. 3512 and the second assembly surface 3522 form the anvil axis 35A in a detachable state.

藉此,當該擊砧軸35A因使用在擊砧部351A或偏心軸部352A產生局部變形或彎曲時,則使用者將能夠單獨進行更換,而不需要將整根擊砧軸35A換掉,可以降低更換時的成本。 Thereby, when the anvil shaft 35A is locally deformed or bent due to use in the anvil portion 351A or the eccentric shaft portion 352A, the user will be able to replace it separately without replacing the entire anvil shaft 35A. It can reduce the cost of replacement.
