Description

Ratchet wrench structure

The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure which is provided with a control group, and the user can dial the cover body so that the control group is interlocked to control the displacement of the tooth.

As previously known to us, the conventional ratchet wrench structure is as described in U.S. Patent No. US7827886B2, and Taiwan Patent Application No.: 097131409, the patent name: a toggle type reversing ratchet wrench, a toggle type reversing ratchet wrench, including The main body 10 is provided with a driving portion 11 at one end thereof. The driving portion 11 is connected to a holding portion 12. The driving portion 11 is provided with a first receiving portion 13 and a tangent to the first receiving portion 13. The second accommodating portion 14 is open to the top of the second accommodating portion 14 of the body 10; a swaying member 20 is rotatably disposed in the first accommodating portion 13 of the body. The side wall ring of the outer edge of the ratchet member 20 is provided with a tooth 22; two latching members 30 are respectively slidably disposed at two ends of the second receiving portion 14 of the body 10, The two latching members 30 are provided with teeth 22 on one side of the opposite side of the ratchet member 30. The top surfaces of the opposite ends of the two latching members 30 are respectively provided with a guiding portion 32, and an elastic body is disposed between the two latching members 30. a reversing member 40, one end of the reversing member 40 is pivotally disposed at one end of the rocking member 30, and the other end of the reversing member 40 is closed to the second receiving portion 1 of the body 10. 4, the second accommodating portion 14 is closed, and the inner edge of the other end of the directional member 40 is provided with a guiding portion 42 corresponding to the two guiding portions 32 of the two latching members 30, and the guiding portion 42 is selectable The guiding portion 32 of the latching member is configured to separate the teeth 22 of the latching member 30 from the teeth 22 of the ratchet member 30.

But the missing structure of this custom structure is:

1. As shown in the cross-sectional view of the fourth figure of the U.S.A., the reversing member 40 is pivotally disposed at one end of the ratchet member 20, that is, the ratchet member 20 is in contact with the peripheral surface of the reversing member 40. The other end of the reversing member 40 controls the guiding portion 32 of the latching member 30. When the reversing member 40 is rotated, the latching member 30 is rotated to control the latching member 30 and the ratchet member 30. The pieces 20 are engaged or disengaged, but when the ratchet member 20 is rotated by three hundred and sixty degrees, the friction between the ratchet member 20 and the circumferential surface of the reversing member 40 should be such that the reversing member 40 rotates. Naturally, the other latching member 30 is engaged with the ratchet member 20, that is, the automatic commutation is lost.

2. When the ratchet member 20 is rotated by three hundred and sixty degrees, the number of the reversing member 40 is also interlocked to slightly shift the latching member 30, and the engaging state between the latching member 30 and the ratchet member 20 is That is, the meshing is not true.

In view of the lack of the structure of the ratchet wrench of the above-mentioned conventional patent case, the inventor has borrowed years of experience in related industries, and finally has a product that can solve the drawbacks of the ratchet wrench structure.

The conventional ratchet wrench structure will be automatically reversing In the absence of the ratchet wrench structure of the present invention, a control group is provided, and the user can dial the cover body, so that the control group controls the displacement of the tooth, and the ratchet does not contact the cover system without automatic change. Missing it.
