The ratchet wrench uses a ring to drive a change element (heart ber) to produce positional changes in both directions, and the front end of the transform element is provided with a pressing member 4 and a resilient member (heart ele_t). ) to elastically push the fresh claws (the υ, so that the claws can be controlled to move between the two positions 'and spit on the rotating element (5) ~ member) ° first notice that this reversing ratchet wrench is A toggle piece is pivoted on the rotating element and is operable by the user, and then the crane ring can perform the reversing action. A lengthwise groove (si〇t) is provided in the tip piece (tiPPiece) formed at the end of the ring: and the transformation element is provided with a circular protrusion (pr〇trusion) at one end, the lengthwise The closing groove allows for a reciprocating longitudinal movement within it, thereby enabling the shifting element to produce a pivotal movement. During the operation of switching the dials in different directions, since the ring uses the elongated slot to drive the protrusion of the changing element, the edge of the two parallel sides and the protrusion will generate frequent friction, and such friction is formed. To make the resistance of the 201116372 user before the toggle piece is swiped, the user must use a considerable thrust to push the dial piece to achieve the switching direction effect. However, after the repeated switching action, the two parallel sides of the groove and the outer periphery of the protrusion may generate a lot of iron filings due to the reciprocating back and forth friction, and the iron filings are easily caught on the two parallel sides of the groove and the outer periphery of the protrusion. Between the formation of obstacles in the switching action. This unsmooth switching usually affects the user deeply and steadily, resulting in a bad evaluation of the product. Moreover, it is more serious that the user may over-apply during the toggle process to cause deformation or damage of the ring and the change element, thus causing a problem of excessive product fatigue or short life, in view of the aforementioned problems. Without being reasonably overcome, the applicant has filed this patent application to solve the aforementioned problems. SUMMARY OF THE INVENTION The purpose of the ratchet wrench of the present invention is to make the switching of the control member smoother. The technical means is to make the first side of the control slot contact the outer periphery of the guiding portion of the reversing switch, and the first side and the guiding The angle between the tangent formed by the tangential section and the second reference line of the reversing switch is no more than forty-five degrees. Thus, if the user wants to move the control member from the first position to the second position, most of the turning force applied by the user to the control member will be used to push the guiding portion of the reversing switch. The rotation of the reversing switch relative to the pivot slot does not cause the control member and the reversing switch to become stuck or the rotation is not smooth, so the user (4) easily touches the complement of the control member to drive the control slot to change the 201116372 direction. The switch moves. = The purpose of the hair wheel wrench is to make the switching of the control piece smoother. ^Easy to move easily 'The technical means adopted is that the first side of the control groove is in contact with the outer circumference of the guiding portion of the reversing off, and the first - The angle between the tangential line formed by the tangential portion of the guide portion and the second reference line of the reversing switch is between 18 degrees and 28 degrees.
