Description

Ratchet wrench structure

The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure in which a first steering member is restricted by a top cap and teeth and is pivotally arranged at the third receiving slot without being disengaged. The second steering member Restricted by the restricting member and being pivotally installed at the third receiving slot without being disengaged, when the first steering member and the first steering member are pivoted at the third receiving slot of the body, it is even more impossible to cause Other factors.

According to my previous knowledge, the conventional ratchet wrench structure with reversing is used, such as US patent case number: US6918477B2, Taiwan patent case application number: 092209021, certificate number: M247346, patent name: direction control device for hand tools and reversing ratchet wrench The structure of the patent case lies in: a hand tool direction control device 100 for switching the rotation direction of a ratchet WH of a wrench W, wherein the wrench W has a first surface S1 and a second surface S2, the direction control The device 100 includes: a first control member 110 having a first pivoting head 112 and a first dial 114; wherein the first pivoting head 112 is pivotably mounted on a first part of the wrench W Surface S1; a second control member 120 having a second pivoting head 122 and a second toggle portion 124, wherein the second pivoting head 122 is pivotably mounted on the second surface of the wrench W S2; wherein the first control member 110 and the second control member 120 are operatively connected to each other, so that the first control member 110 and the second control member 120 pivot synchronously.

But the lack of this conventional structure lies in:

1. As shown in Figure 2 of the bulletin, the first control member 110 and the second control member 120 of the direction control device 100 are combined, and the projection 116 of the first control member 110 is accommodated. At the groove 126 of the second control member 120, the protrusion 116 and the groove 126 shown in the figure should be adhered with an adhesive or a tight fit between them so that the first The control member 110 is not disengaged from the second control member 120 and can be pivoted synchronously. However, after the wrench W is used for a long time or accidentally dropped during use or the place where the wrench W is used has oily substances, the convex The adhesive or tight-fitting structure between the block 116 and the groove 126 may fail, so that the first control member 110 and the second control member 120 are disengaged from each other to escape the CO of the accommodation hole, FIG. 3 of the publication. The directional control device 200 or the directional control device 400 of the 5A and 5B of the bulletin or the directional control device 500 of the 6A and 6B of the bulletin also have the same defects.

2. As shown in FIG. 4, if the first control member 310 and the second control member 320 are combined with each other by using a screwing member 300, the second control member 320 can be seen from the appearance of the wrench W The end face of the control member 320 is provided with the screwing member 300. The screwing member 300 makes the appearance of the wrench W insufficient.

In view of the lack of the above-mentioned conventional structure, the inventor has, through years of manufacturing, production and design experience in related industries, finally come up with a product that can solve the conventional drawbacks of a ratchet wrench structure.
