Description

Ratchet wrench structure

The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure, wherein the tooth system is provided with a second tooth portion and a third tooth portion, so that the ratcheting function of the ratchet wrench structure is more accurate.

The ratchet wheel 81 and the toothing 82 of the conventional ratchet wrench structure are as shown in the sixteenth and seventeenth drawings. The ratchet wheel 81 is provided with a fourth tooth portion 811 which is annularly arranged, and the fourth tooth portion 811 is attached thereto. A second tooth peak 8111 and a second tooth valley 8112 are provided. The fourth tooth portion 811 includes a seventh side surface 8113 and an eighth side surface 8114. The two second tooth peaks 8111 or the second tooth valley 8112 are interposed. A seventh side surface 8113 and an eighth side surface 8114 are provided. The front side of the toothing 82 is provided with a plurality of fifth tooth portions 821, and the fifth tooth portion 821 of the tooth 82 is coupled to the fourth tooth of the ratchet 81. The portion 811 is engaged, and the fifth tooth portion 821 includes a ninth side surface 8211 and a tenth side surface 8212. The seventh side surface 8113 is parallel or slightly parallel with the tenth side surface 8212 and abuts against each other. The eighth side surface 8114 is parallel to the ninth side surface 8211 and abuts against each other.

However, the missing structure of the conventional ratchet 81 and the tooth 82 is:

Each of the fifth tooth portions 821 of the ratchet wrench structure of the conventional ratchet wrench structure is fully engaged with the ratchet wheel 81. Each of the fifth tooth portions 82 has the same tooth shape, and the fifth edge portion 82 of the outermost edge is clamped to When the ratchet 81 and the ratchet wrench have the smallest gap of the body, the fifth tooth portion 82 of the most edge is disposed at the small gap, and the ratchet 81 of the fifth tooth portion 82 at the most edge is rotated. Smooth tooth skipping phenomenon.

In view of the fact that there is a problem that the fifth tooth portion 821 of the outermost edge of the conventional tooth 82 and the fourth tooth portion 811 of the ratchet 81 have a smooth tooth-toothing phenomenon, a fifth tooth portion 821 of the outermost edge is often given. After the fifth tooth portion 821 of the outermost edge is removed, there is no tooth-toothing phenomenon, but the tooth 82 has two left and right edges, so that the tooth 82 has two fifth tooth portions 821. There is less tooth engagement between the tooth 82 and the ratchet 81, and the twisting force between the two is lost, causing another loss.

In view of the above-mentioned lack of the conventional ratchet wrench structure, the inventors have been engaged in the manufacturing experience of related industries for many years, and finally have a product that can solve the drawbacks of the ratchet wrench structure.

The fifth edge of the edge of the conventional ratchet wrench The tooth system affects the tooth skipping. The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure, the tooth system is provided with a second tooth portion and a third tooth portion, so that the ratcheting function of the ratchet wrench structure is achieved. More sure.

A ratchet wrench structure, comprising: a book The system is provided with a first receiving groove, a second receiving groove and a first abutting surface; a ratchet is pivotally disposed in the first receiving groove, and the outer periphery of the ratchet is provided with a first toothed portion arranged in an annular shape, each of a first tooth peak and a first tooth valley are disposed on the first tooth portion, the first tooth portion includes a first side surface and a second side surface; and a tooth system is disposed in the second cavity On the side, the tooth system can be displaced to the left and right in the second cavity, and the front side of the toothing is provided with a plurality of second tooth portions, each of the second tooth portions meshing with each of the first tooth portions. Each of the second tooth portions includes a third side surface and a fourth side surface, and the third side surface is parallel and opposite to the second side surface, and the fourth side surface is opposite to the first side surface Parallel or slightly parallel and abutting against each other, the third edge of each of the left and right sides of the tooth is provided with a third tooth portion, the third tooth portion is different from the second tooth portion, and the third tooth portion is not Engaging with the first tooth portion, the third tooth portion is close to the first a tooth unit; a control unit controls the teeth to be displaced left and right in the second tank to control the forward and reverse rotation of the ratchet wrench.

When the ratchet wrench structure is to be retracted, the card system is When the elastic force of the elastic element abuts against the left side of the concave arc groove of the tooth making, all the second tooth portions at the right side of the tooth and the third tooth portion at the rightmost side are separated from the ratchet, and the tooth is Rotating slightly at the second pocket, so that the first tooth peak of the ratchet will abut against the fifth side surface, so that the second side surface is pressed against the fifth side surface to help the third tooth portion efficacy. The third tooth portion of the tooth is different from the second tooth portion, and the first tooth peak portion is abutted against the fifth side surface, so that the first tooth peak is pressed against the fifth side surface to help the third The tooth flicking function is such that the first side surface and the second side surface of the first tooth valley can be acutely angled, that is, the angle between the first side surface and the second side surface is less than ninety degrees. The one side surface and the second side surface are acutely angled, and the third side surface and the fourth side surface are also acutely angled, and each of the first tooth portions and each tooth portion has a larger meshing area, and the teeth are The torque between the ratchets can be greater.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
