Open end wrench structure

The creation department is related to the structure of the open-end wrench, in particular, an open-end wrench structure is provided with a slider, and the slider is displaceable at the opening of the body, so that the screwing member is directly retracted at the body, the opening The wrench has a ratchet effect.

As previously known to us, an open-end wrench patent having a ratcheting effect or a fast-turning effect is used, such as U.S. Patent No. 3,023,654, which is based on a body 10 that is a wrench-like body. The end of the working end of the head portion 18 is provided with a receiving groove 28, and the end portion of the receiving portion 28 is provided with a resisting portion 30 for restraining the end portion of the receiving groove 28 into a restricted shape. The end of the slot 28 is provided with a screwing portion 54. The screwing portion 54 is in the shape of an internal screw hole. The slider 26 is received in the slot 46 of the body 10. The slider 26 is The abutting portion 36 is formed in a convex arc shape and protrudes from the opening of the body 10. The abutting portion 36 is provided with a sliding portion 58. The sliding portion 58 is shaped to be compatible with the receiving groove 28 and Displaceable, the bottom portion of the sliding portion 58 is convexly provided with a rod portion 42; a fastening member 50 is received in the cavity 28 of the body 10, and the fastening member 50 is externally Threaded, the fastening member 50 is a screwing member, and the fastening member 50 is screwed to the screwing portion 54 of the receiving slot 28, and a through hole 52 is formed in the center of the fastening member 50. The end 42 of the slider 26 Compatible An elastic member 48 is sleeved on the rod portion 42 of the slider 26, and the elastic member 48 is fastened between the sliding portion 58 and the fastening member 50, so that the slider 26 is attached to the body 10. The elastic displacement in the groove 28 makes the open wrench have a ratchet effect.

But the lack of this patent lies in:

1. As shown in the third figure of the U.S. Patent Publication, the slider 26, the elastic member 48, the fastening member 50, and the body 10 are provided with a screwing portion 54, so that the slider 26 can be placed on the body 10. The elastic displacement effect in the groove 28 is provided with three components, that is, the cost of the component is increased. The screwing portion 54 needs to tap the screw to increase the processing cost of the body 10. The diameter of the cavity 28 is not large, and the thread is required to be tapped. There are difficulties.

2. As shown in the second figure of the U.S. Patent Publication, the slider 26 is received at the receptacle 28, and the slider 26 is abutted against the elastic force of the elastic member 48, so that the slider 26 is at the receptacle 28. The elastic displacement function, but the front end opening of the cavity 28 of the main body 10 is provided with a resisting portion 30. The restriction of the resisting portion 30 prevents the slider 26 from falling out of the opening due to the elastic force of the elastic member 48. However, the position of the body 10 is not difficult to calculate. The position of the resisting portion 30 is such that the abutting portion 36 of the slider 26 is exposed outside the opening and needs to be abutted on the side of the screwing member 34. If the position of the abutting portion 30 is too inward, the abutting portion 36 of the slider 26 is exposed to a small volume at the opening, and the abutting portion 36 cannot abut against the side surface of the screw member 34, and the screwing is screwed. The gap of the piece is relatively large, and if the position of the resisting portion 30 is too outward, the abutting portion 36 is convexly protruded into a large volume, and the screwing member is blocked by the slider 26 when the screwing member is fitted, and the side of the screwing member is The face system needs to bring the slider 26 back correctly. position.

3. If the position of the resisting portion 30 is too inward, the abutting portion 36 of the slider 26 is insufficiently convex, and if the resisting portion 30 is to be processed into the cutting portion, the slider 26 is protruded to the correct position. The technique of cutting a small thickness is difficult. Generally, the thickness of the cutting volume is at most 0.5 mm, and the cutting height of 0.5 mm is relatively precise. If the body 10 is a defective product, the cost is higher. .

In view of the structure of the above patent case, the creator has accumulated many years of experience in the manufacture of open-end wrenches, and after several trials and trials, he has finally obtained a practical application.

The new problem to be solved: the open-end wrench with fast-acting effect or ratcheting effect has many parts and cost. The open-end wrench structure of the present invention is provided with a slider, which is attached to the opening of the body. It has a displaceable shape, so that the screwing member is retracted directly at the body, and the open-end wrench has a ratcheting effect.
