Description

Ratchet wrench structure

The invention is related to the structure of the ratchet wrench, in particular, the first body and the second body of the ratchet wrench are pivoted with the pivoting member, and the first system is provided with the missing slot and the first limiting portion, the second This system is based on the first restriction.

As previously known to us, the conventional ratchet wrench structure, such as U.S. Patent No. 8245602, Taiwan Patent Publication No. M377291, is based on: Figure 1 of the U.S. Gazette, U.S. Application and Taiwan Application The component number is different, which is based on the number of the U.S. application. 1. A non-reversing button ratchet wrench includes a headstock 10 having a through hole 11 extending through the bottom surface at intervals on the top surface. a circular groove 12 that does not extend through the bottom surface, the circular groove 12 has a radial notch 13, and the control circular groove 12 has an arc of more than 1 π, and the headstock 10 is further closed by a top surface and a bottom surface. 14 is connected to the insertion hole 11 and the circular groove 12; a ratchet 20 is pivotally disposed in the insertion hole 11 of the headstock 10, the ratchet 20 has a driving portion 24, a ring portion 21 disposed outside the outer circumference; The block 30 has a left-right width smaller than the left and right widths of the cassette chamber 14 and is disposed in the cassette chamber 14. The ratchet block 30 is provided with a latch 31 capable of engaging the external tooth portion 21 of the ratchet 20; and a handle 50. The shaft block 51 is pivotally disposed at one end of the circular groove 12, and the shaft block 51 elastically interlocks the ratchet block 30, When the handle 50 is swung left and right in the notch 13, the ratchet block 30 can be controlled to be reversely positioned on the side wall surface of the cassette chamber 14 for switching the ratchet wheel 20 Turn.

However, the missing structure of the US patent case 8245602 is:

1. In addition, as shown in the third figure of the U.S. Gazette, when the clockwise rotation is performed, the shaft block 51 of the handle 50 is pivotally disposed at the circular groove 12 of the headstock 10, and the neck portion 55 of the handle 50 is The circular groove 12 is a groove chamber that does not penetrate the bottom surface, and the neck portion 10 drives the head block 10 to drive the ratchet block 30 to rotate the ratchet wheel 20, and the neck portion The driving power of the headstock 10 drives the side of the notch 13 to one side, and as shown in Fig. 4, the side of the notch 13 is spread to the other side when the counterclockwise is rotated. After the two side faces of the notch 13 are opened, the rotation power of the ratchet wrench is lost.

2. Attached to Figure 1 of the U.S. Gazette, the cover 60 is coupled to the circular groove 12 of the headstock 10 by a second buckle 61, so that the shaft block 51 of the handle 50 is pivoted to the head. The circular groove 12 of the seat 10, but the rotational force of the handle 50 driving the headstock 10 is not completely horizontal, the vertical force between the handle 50 and the headstock 10 is received by the cover 60, and the cover 60 is only the second The buckle 61 is supported, so that the rotation power of the handle 50 easily causes the cover 60 to be disengaged from the circular groove 12 of the opening seat 10. The strength of the joint structure between the cover 60 and the circular groove 12 is insufficient.

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

In the US patent, the lack of the head seat There is a lack of two sides in the mouth, and the ratchet wrench structure of the present invention The first body and the second body are pivoted with the pivoting member, and the first system is provided with a notch and a first restricting portion, and the second system is abutted against the first restricting portion.
