directions, and the front end of the transforming element is provided with a pressing element (elastic element) to elastically push the pawl ( The cough pawl can be tilted to control the two recording movements and is compounded on the drive member. First, it can be noticed that the reversing ratchet wrench is replaced by a reversing plate (reVerSingplate). The action of the plucking piece is dragged on the rotating element and is operable by the user. Many work situations must be carried out by the user to lift the head, and the square end of the rotating element of the ratchet wrench is turned upward (opposite to the ground) Gravity), the upper end of the rear end of the rotating element is connected to a sleeve or sleeve to extend the special item 'in such a case, Han Xu θ extends the post, etc. _ weight, sometimes also: two; ^^ At this time, when the right user wants to switch the direction of the spine and operate the dial, it will be difficult to switch the toggle #, so the sleeve or sleeve must be extended by the post, etc. The head end is removed, so that the square end of the rotating element faces downwards, so that the direction of the dial piece can be properly switched, which is inconvenient to use. When the user operates the dial piece, the ring moves along with the dial piece, so that the ring moves along with the dial piece. The end faces of the ring and the rotating element generate a friction. Under the long-term repeated operation, such friction causes the ring to wear, which in turn causes a problem that the iron filing operation is not smooth. In order to make the dial piece have a good positioning effect. Usually, the positioning structure is processed on a wrench, such as a pin and a pin hole. ' Then the positioning device on the dial is used to position the pin, but the design of the positioning structure on the wrench is usually As the cost of the entire reversing ratchet wrench increases, the market demand is not easy to expand, which constitutes a hindrance to sales. » Moreover, the associated parts connected between the dial and the shifting element are equivalent to each other. Existence, so when the user operates the dialing film, the day-to-day meeting will become a late delay in the operation of each part, and the conversion element will be produced, and the problem of insensitivity If the operation is not sensitive, the wrench cannot be upgraded to the same grade, so that it is not irritating; the desire of the purchaser is the same. [Disclosed] The technical problem to be solved by the ratchet wrench of the present invention is mainly for the conventional connection. There are quite a few related parts, and the control member of the present invention directly interlocks the reversing switch', thereby effectively improving the operation of the operation and reducing the occurrence of errors. Moreover, since the closing section of the driving body is close to the pole-to-pole, the end body is facing the body. The plane is in contact with the body, and the bottom surface of the control member is in contact with the first flat 1354606 2 of the body. During the process of switching the control member, even if the user pushes the driving column of the driving body of the ratchet wrench toward the upper side (opposite to the gravity of the earth) And the connecting sleeve or the sleeve extends the articles such as the post, the control member is still phased, switched, and the problem that it is difficult to switch is not caused. At the same time, the control member does not have the disadvantage of being worn by the end face of the rotating drive body, and the control member is used more and can be used to increase the life. The secondary purpose of the 扳手? wrench is that the conventional positioning structure must be provided. The control member of the present invention is disposed between the control member and the reversing switch in the pivoting column production county (10) of the driving body, which can effectively reduce the ratchet of the present invention. Another purpose of the wrench is to create two two-position relationships in the positional end of the position-to-peak switch. Due to the fixed and optional 控制 of the control member, it is not necessary to add additional = effective enough reduction on the wrench body. Cost of production.

The half-pinch distance of the reset portion of the positioning member 53 and the axis of the perforating axis is smaller than the axial center of the positioning groove 532 and the pivot hole 51. The distance of the line is reduced. Therefore, the resetting portion 533 can apply a force to the position of the reversing switch 40 to cause the positioning member 53 to automatically accommodate one of the two positioning grooves 532 to the positioning portion 423 of the reversing opening 1354606. Referring to Figures 5 and 6, the control member 50 is in the flute state. When the control master is in the first position, the two positions accommodate the positioning portion 423 of the reversing switch 40, so that one of the control members 曰t is properly positioned by the switch 4G. The bump 422 of the reversing switch 40 is located at the end of the control away from the pivot hole 51, so that the reversing switch 4^=slot 521 is pushed up in the pocket of 30 concave _2, so that the card body The movable body 2, which is formed by meshing with the driving body 2〇4, can be opposed to the second. The command is to say that the user operates the body 10 to turn counterclockwise. - Rotate counterclockwise (because _0 has no = drive shun = move) 'So you can make the (four) body 20 counterclockwise ^= 4 according to Figure 7, for the control part 5Q from the first position to /, Schematic diagram of the process. When the user dials the control member 50, if the __t multi-moving control member 50 is rotated counterclockwise with respect to the body 10, the replacement of the block will be pivoted in the sliding slot 521 of the control member 50. When the resetting portion 53 of the positioning member 53 = 4 〇 of the positioning portion 423, at this time, the positioning portion 53 of the aligning member 53 switches the positioning portion 423 of the switch 40 to cause the control member to reversing the force, so that the control member 50 can automatically move and set. Referring to FIG. 8 and FIG. 9 in situ, when the control member 5 () is located at the second position of the fth control member 5°, the two positions (four) are: the valley reversing portion is similar to the control member __ The good positioning effect β provided by the Lai 1354606 to the switch 40 and the block 422 of the reversing switch 40 are located in the control member 5〇 away from the end of the pivot hole 51, so that the diversion switch 4〇 is pushed on the card. The block 30 has the side of the recessed portion 32, so that the latching block _20 shape "synthesizes the driving body 2G to have a one-way turning effect. = The driving body 20 can be rotated clockwise relative to the main body 1 2, 2 says that when the user operates the body 10 to rotate clockwise, it can rotate clockwise with the second moving body 20 (because the driving body 20 cannot be rotated relative to the counterclockwise, so the closing, _ body 2 () The needle is turned into a rainbow. And because the driving segment H21 of the driving H20 is close to the pivoting column (four) - the end system = the first plane 121 of the body 10 and 1 () contact, the bottom surface of the control (4) is in contact with the first plane 121 of the body ,), so in the process of switching the control member t 'even if the finer will pull the ratchet (four) shaft body 2 buckle the eye gravity), and boots _ 23: = or the sleeve extends the post and other items, the control (4) is still quite easy to cut = no problem that is difficult to switch. At the same time, the control member 5〇 is not subject to the end face of the driving body 20 in the twirling; the x 丄 & parts are 50 times less worn by the 1 test pill, so that the control member 50 can be used more smoothly and can be used. Increase the service life. As far as the above is concerned, __ this (4) has the following advantages: ^ Turning b-month ratchet wrench' where the control is directly linked to the commutating opening 〖This effectively improves the operational sensitivity and reduces the occurrence of errors. Zhiben 彳X lin wheel wrench, its towel control piece is set on the hinged low-production Si locating piece set between the control part and the reversing switch' can effectively reduce 1354606 enough 2: wrench, its The positioning member is provided with two positioning grooves, which can generate two selective clamping positions due to the positioning of the control member na 4 at the interlocking end of the reversing switch, so that no additional processing on the wrench body is required to reduce the production cost. Therefore, the structure is effective enough: the second is only the preferred embodiment of the present invention, and when the range of the component ==: cannot be changed, the change of the numerical value or the equivalent element change and the repair [simplified description] The figure is a three-dimensional appearance of the ratchet wrench of the present invention.
