New description: [New technical field] The new type is related to a type of return wrench, and in particular to a wrench that does not need to be pulled out of the driven member to make the operation fast and smooth. [Prior Art] A conventional recovery wrench, such as the new patent application No. M338722 "Wrench", provides an easy-to-insert driven member (such as a bolt and a nut) by an open drive head, and is adjusted and adjusted. The purpose of driving the driven member is achieved. Due to the driving portion of the wrench, the diameter of the opening is a single size type '4, and the size of the opening is matched with the fixed size of the driven one outer #, when the wrench drives the driven member to a rotation angle The wrench is completely disengaged from the driven member, and then the opening of the wrench is put into the driven member again. Thus, not only the working time is increased, but also the driven member must be focused on the wrench. Accurately reinsert the driven part. At the same time, the problem of inconvenient use of the existing reply wrench will increase involuntarily = a lot of inconvenience, which is one of the problems that the operator who operates this reply has not been able to overcome in the operation for a long time. [New content] f The new purpose is to provide a wrench that uses the return part to adjust the back (four) degree of the wrench so that the wrench does not need to be completely detached from the driven part', making the operation more convenient, quick and smooth. A wrench according to the present invention comprises a grip and a drive head to M358038. The driving head is coupled to the end of the grip and has: an open driving portion' the driving portion includes a plated portion at the closed end, and a circular arc-shaped return portion at the open end, the returning position The large width of the table is greater than the maximum width of the pulling portion, and the opening of the open end is smaller than the maximum width of the pulling portion. According to the above-mentioned wrench of the present invention, there are two driving heads, one of which is located at one end of the grip, and the pulling portion is a groove type. The other drive head is located at the other end of the grip. The drive portion of the drive head is in a ratcheted configuration. According to the above-mentioned wrench of the present invention, the pulling portion of the driving head is a groove type. According to the above-mentioned wrench of the present invention, the plated portion of the drive head is in a ratchet shape. [Embodiment] Referring to Figures 1 and 2, a first embodiment of the novel wrench 10' includes a grip 1 and a second drive head 2, 30. The grip 10 has a front end 11 and a distal end 12. The drive head 20 is coupled to the front end 11 of the grip 1 and has an open drive portion 21. The driving portion 21 includes a pulling portion 211 at the closed end and a circular arc-shaped return portion 212 at the open end. The maximum width D1 of the return portion 212 is larger than the maximum width D2' of the pulling portion 211 and the width D3 of the opening 213 at the open end is smaller than the maximum width D2 of the pulling portion 211. 4 M358038 Another drive head 30 is coupled to the end 12 of the grip 1 , and the drive portion 31 of the drive head 30 is in the form of a ring-shaped ratchet. Referring to FIG. 2, when the driving member 4 is driven, the pulling portion 211 of the driving head 20 is fitted into the driven member 40 from the top of the driven member, and the pulling portion 211 of the driving head 2〇 It is tied to the outer peripheral side of the driven member 4A. At this time, the execution of the driven member 40 can be started.
參照第3圖，接著，當扳手1GG位移至-角度， 可將扳手第3圖的箭頭方向移動，致使被驅動件如 自扳動4位211脫出，並進人該驅動頭2()的回復部 位212，此時，該被驅動件40受限於開口 213，而不 會使扳手100整個脫離被驅動件4〇。 μ續參照第4圖’此時，可藉由此回復部位212沿 第4圖的箭頭方向來調整扳手1〇〇的位置。 口 續參照第5圖，調整好位置之後，再將板手⑽ 沿弟5圖的箭頭方向位移，讓驅朗2()的扳動部位 叫再次滑入該被驅動件40的外周側，即可繼續執行 驅動該被驅動件的動作。 口此本新型的扳手100於執行被驅動件40時， 扳手無須完全脫離被驅動件4 〇，而利用㈣頭2 q的 回復部位212來作為迴轉的空間，以利用工作進度之 進行，並增加工作之順暢度。 人參照第6圖，本新型扳手期的第二實施例，包 3—握把1〇及二驅動頭50、6〇。該第二實施例的驅 M358038 動頭50是一開放凹槽的型態’且無第1圖的回復部 位212。而該驅動頭60是一開放的棘齒型態，係在棘 齒型悲扳動部位611前端設有回復部位612，而且驅 動頭60的開放端之開口 613小於該扳動部位611的 最大覓度。戎第二實施例的使用功能與前述實施例相 同，此不再贅述。 如上所述，相較於現有回復扳手之操作不便，徒 φ 增作業時間的使用問題。本新型的扳手，可利用該驅 動頭20、60的回復部位212、612來調整扳手1〇〇、 2〇〇的迴轉位置，扳手100、200無須脫出被驅動件 40,因此，本新型具有操作簡便快速，且動作順暢的 作用，而且，操作者只憑感覺即可使被驅動件40在 扳手100、200之該驅動頭20、60的扳動部位2U、 1 .、回復^位212 ' 612之間來回往返，故可提升作 業速度。 春 惟以上所述者，僅為本新型之二個實施例而已，Referring to FIG. 3, next, when the wrench 1GG is displaced to an angle, the direction of the arrow of the wrench 3 can be moved, so that the driven member is disengaged from the self-clamping 4 position 211, and the reply of the driving head 2 () is entered. The portion 212, at this time, the driven member 40 is limited to the opening 213 without completely detaching the wrench 100 from the driven member 4. Referring to Fig. 4' at this time, the position of the wrench 1〇〇 can be adjusted by the returning portion 212 in the direction of the arrow in Fig. 4 . Referring to Figure 5, after adjusting the position, the wrench (10) is displaced along the arrow direction of the figure 5, so that the pulling portion of the drive 2 () is slid into the outer peripheral side of the driven member 40 again, that is, The action of driving the driven member can be continued. When the wrench 100 of the present type is used to execute the driven member 40, the wrench does not need to completely disengage from the driven member 4, and the return portion 212 of the (4) head 2 q is used as the space for the rotation to utilize the work progress and increase The smoothness of work. Referring to Figure 6, a second embodiment of the novel wrench period, the package 3 - the grip 1 and the second drive head 50, 6 〇. The drive M358038 of the second embodiment is in the form of an open groove and has no return portion 212 of Fig. 1. The driving head 60 is an open ratchet type, and a returning portion 612 is disposed at the front end of the ratcheting type swaying portion 611, and the opening 613 of the open end of the driving head 60 is smaller than the maximum 觅 of the pulling portion 611. degree. The function of the second embodiment is the same as that of the previous embodiment, and details are not described herein again. As described above, compared with the operation of the existing return wrench, the use of the working time is increased. The wrench of the present invention can adjust the swing positions of the wrenches 1 and 2 by using the return portions 212 and 612 of the drive heads 20 and 60. The wrenches 100 and 200 do not need to be disengaged from the driven member 40. Therefore, the present invention has The operation is simple and quick, and the action is smooth. Moreover, the operator can make the driven member 40 on the driving parts 20, 60 of the wrenches 100, 200, the pulling parts 2U, 1 . 612 back and forth between the two, so it can improve the speed of the work. Spring, as mentioned above, is only two embodiments of the present invention.
