Description

Ratchet wrench structure

The present invention relates to a ratchet wrench structure, in particular to a ratchet wrench having a second curved surface and a third curved surface, so that the body has a large rotating area between the tooth and the tooth.

As previously known, the conventional ratchet wrench structure, such as U.S. Patent No. 6,282,992, is supplemented by the first figure. The ratchet wrench of the patent is provided with a body 10, a ratchet 20, a tooth 40, a steering knob 50 and The basic components such as the moving body 60.

Referring to the third, fourth and fifth figures, the body 10, the ratchet 20, the toothing 40, the steering knob 50 and the actuating body 60 are basic components constituting a ratchet wrench, and the steering knob 50 is When the three-receiver slot 15 rotates, the strap action body 60 rotates at an angle, and the actuating body 60 drives the tooth 20 to shift left and right at the second pocket 14 to form a positive reversal control of the ratchet wrench, which is also a ratchet The principle of the positive reversal of the wrench, the shape of the tooth 40 is slightly similar to the moon, so the industry system said that the tooth 40 is a monthly eyebrow.

However, this US patent system has the following missing:

1. In addition, as shown in the third figure of the bulletin, the tooth 20 of the U.S. Patent 6,282,992 is displaced to the left and right at the second pocket 14 to take into account the smoothness of the displacement of the tooth 20, so the rear side of the tooth 20 Different from the arc surface of the second pocket 14, the rear side of the tooth 20 is basically composed of at least three curved surfaces, so that the rear side of the tooth 20 has only a partial surface and a second surface. The arc surface of the pocket 14 is in contact with each other, that is, a portion of the surface at the portion 44 is in contact with the second pocket 14. When the body 10 drives the tooth 20, the contact surface of the second pocket 14 with the tooth 20 is rotated. There are quite a few twists and there is a lack of twisting torque.

2. In addition, as shown in the third figure of the bulletin, the second pocket 14 has a curved surface, and the rear side of the tooth 20 is basically composed of at least three faces, and the design is a 19MM ratchet wrench. That is, the arc surface size of the second pocket 14 needs to be designed and the dimensions of the three sides of the rear side of the tooth 20 are designed. The arc surface of the left and right sides of the tooth 20 is basically the arc surface of the second pocket 14 . The radius is the same, but the middle surface is designed to have a curved surface size to connect the curved surfaces on the left and right sides. The design variables are more complicated, and the ratchet wrench has a considerable size from 8 to 32, and each size is designed to be four. The curved surface system is quite time consuming.

In addition, the structure of the U.S. Patent No. 893097, 5533427 or 6516690 is in principle that the teeth are displaced to the left and right at the second pocket to form a positive and negative rotation of the ratchet wrench, and each has the same defect of 6,282,992.

In view of the above-mentioned conventional ratchet wrench structure, the creator has been researching and developing through years of experience in related industries, and finally has a ratchet wrench structure product.

The main purpose of this creation is to solve the problem that the conventional ratchet wrench has less contact surface and less torque, and the design variable system is more complicated.
