New description: [New technology field] This creation is related to the ratchet wrench, the ratchet wrench. In particular, it is easy to assemble. [Prior Art] The patent publication No. 6,575,060 discloses a kind of "reversible master ===, _ control the ratchet block toward the right while the ratchet block is toward the right, the ratchet block It is possible to provide a coil spring on the bottom surface of the steering control member and to use it as a positioning of the steering control member. /, '· ..., and in the aforementioned patent, 'When the steering control member is assembled When the wrench body is used, the steel ball must be properly engaged with the wrench in the locating hole of the wrench. However, the steel ball is expected to be detached by the elastic force of the _coil spring, and the load is caused by the assembly. Lin carefully cares about the loss, and will lead to an increase in cost. [New content] The main purpose of this creation is to provide a ratchet wrench, which can effectively prevent the steel ball from falling off and has the characteristics of convenient assembly. To achieve the above purpose, the creation The ratchet wrench includes a wrench body, a ratchet, a steering control, a ratchet block, and a positioning member, wherein: the end of the wrench body communicates with each other through the ratchet slot And a pivot hole, and a receiving hole is axially recessed from the hole wall of the pivot hole; the ratchet is rotatably disposed in the ratchet groove of the wrench body; the steering control member is at the - position And the second position is pivotally disposed in the towing hole of the wrench body, and is recessed along the outer circumference thereof to form at least a guiding slot and an adjacent two positioning slots, the guiding slot and one of the positioning slots Separated by a load 2 zone; the ratchet block is connected to the steering control member and is in harmony with the ratchet wheel, and can be driven by the steering control member to change the direction of the ringing between the ratchet wheel and the Controlling the steering of the ratchet; the positioning member has an elastic member ^ steel ball 'Shai elastic member is received in the receiving hole of the wrench body. When the steering control member is in the first position, the wrench body is accommodated The hole and the guiding groove are connected to each other without being blocked by the stopping portion, and are facing the positioning groove adjacent to the guiding groove. At this time, the steel ball can be slidably received by the wrench body. Inside the hole, when the steering control member is rotated to the 4th first position, the receiving hole of the hand body The guiding groove is blocked by the portion and cannot communicate with each other, and is positioned adjacent to the guiding groove; at this time, the steel ball can be engaged by the elastic member to be engaged in the positioning groove, Therefore, it is necessary to worry that the steel ball is dropped in the assembly, so as to achieve the purpose of easy assembly. [Embodiment] The following preferred embodiments are listed in conjunction with the drawings to explain the present construction and efficacy in detail. The second member M429561 40, a ratchet block 50, and a positioning member 60. One end of the wrench body 20 extends through a ratchet slot 22 and a pivot hole 24, and the pivot hole 24 has a large diameter portion 242. And a small diameter portion 244, and a hole accommodating from the hole wall of the large diameter portion 242 along the length direction of the wrench body 20, as shown in the third figure. The ratchet wheel 30 is rotatably mounted via a buckle 32 The wrench body 2 is inside the ratchet groove 22.
轉向控制件40經由一螺絲41而可樞轉地設於扳手本 體20之樞接孔24内，並於其頂、底兩面分別具有呈二角 形之一插孔42及相互鄰接之二定位槽43，如第四圖所示； 此外，轉向控制件40之兩側的周緣分別具有一導槽44， 彼此相鄰之導槽44與定位槽43之間經由一檔止部45而區 隔開來，當轉向控制件40位於一第一位置？1時，如第四 圖所示，扳手本體20之容置孔26與導槽44之間不受擔止The steering control member 40 is pivotally disposed in the pivot hole 24 of the wrench body 20 via a screw 41, and has a polygonal insertion hole 42 and two adjacent positioning holes 43 on the top and bottom surfaces thereof. As shown in the fourth figure; in addition, the circumferences of the two sides of the steering control member 40 respectively have a guiding groove 44, and the guiding groove 44 adjacent to each other and the positioning groove 43 are separated by a stop portion 45. When the steering control 40 is in a first position? At 1 o'clock, as shown in the fourth figure, the receiving hole 26 of the wrench body 20 and the guide groove 44 are not supported.

The supported portion 45 is blocked and is in communication with the positioning groove 43. The bottom surface of the tooth portion 52 extends, and the two portions 52' are from the spine birch 54. The cross-sectional shape of the shaft 54 is also the inner elastic member of the side steering control member 4 () ==42 56 =1 the top of the elastic member 56 and the ratchet 3. Between the two in a good coupling relationship, at the same time can be turned to the axis of the (four) piece and = 5 M429561 /, the direction of the ring between the spine = 30 ' to control the ratchet to turn. The positioning member 60 has a second elastic member 62 and a steel ball 64. The second elastic member 62 is disposed in the receiving hole % of the wrench body 2, and the steel ball is disposed at the top of the elastic member 62. The top of the elastic member 62 abuts and engages one of the positioning grooves 40 as shown in FIG. 5 to position the steering control member 4''. The detailed structure of the ratchet wrench 1 以上 of the above is described below in the assembly process of the creation. - At the time of the group 4, the second elastic member 62 is first accommodated in the valley hole 26 of the wrench body, and then the steering control member 4 is placed through the large portion 242 of the pivot hole 24. The turning (4) member 4G is pivoted from the small diameter portion of the pivoting hole by the screw 41, and then the ratchet groove 22 of the hand body 2 is placed into the guide 44 of the steering control member 4 == 4. Turning to the first position P1, the guide groove 44 of the steering control member is communicated with the receiving hole of the wrench body, such as _, the steel ball 64 can slide along the guiding groove 44 into the receiving hole and then turn The control member 4 turns to the second position p2, and in the turn: 'the steel ball: is pressed by the stopper portion 45 of the steering control member 4, and gradually enters the valley hole 26 while compressing the second elastic member 62. After the supporting portion 45 of the steering control member 40 and the steel ball 64 are offset from each other, the steel ball ^ is pushed by the restoring force of the second elastic member 62 and the engaging member 4 is positioned therein - in the positioning groove 43 to complete the steel ball 64 Ann I: As shown in the fifth figure, the ratchet block 50 is then inserted into the jack 42 of the steering control member, and finally the ratchet 3G is screwed into the spine M429561 22 of the wrench body 2 (). That is to complete the assembly of this creation. It can be seen from the above that the design of the ratchet wrench 10 of the present invention can effectively prevent the steel ball 64 from accidentally falling during the assembly process through the design of the guide groove 44, thereby achieving the purpose of increasing assembly convenience.
