Description

Meshing tool structure

The present invention relates to a rotary tool, and more particularly to an intermeshing rotary tool structure that can be rotated for a worn or damaged workpiece.

According to the general construction, the consolidation operation often uses a wrench to drive the nut or the bolt head. In use, the sleeve is first sleeved on the wrench, and then the sleeve is sleeved on the nut or bolt head. In turn, the wrench is rotated to drive the sleeve, and the nut or bolt head is rotated together for locking or loosening operation. However, since the corner angle of the head of the nut or bolt may be worn or damaged after long-term use, the sleeve on which the sleeve is placed may be relatively slipped when rotated, so that the screw cannot be driven. The cap or bolt head is used for locking or loosening operation. In view of this, there is a sleeve technology. As shown in Fig. 1, the sleeve 90 has a sleeve hole 91 at one end thereof corresponding to a screw. At the center of each side of the cap 100 (or the bolt head), there is a card indentation 92 which is tapered inwardly, and the sleeve 90 is clamped to the nut 100 by the card abutment 92 (or a bolt) At the center of each side of the head, the nut 100 (or the bolt head) can be rotated. However, since the contact of the nut 100 (or the bolt head) is only a point contact, the faces in contact with each other are limited, so that the force that can be locked or loosened by the nut 100 (or the bolt head) is insufficient. There is still a situation in which the nut 100 (or the bolt head) cannot be driven.

In order to solve the problem that the sleeve and the nut (or the bolt head) are relatively slid during rotation, a non-slip sleeve technology is produced. For example, in the new patent No. M323375, please refer to FIG. 2, which provides a The anti-slip sleeve of the forward and reverse force application is provided with a hexagonal sleeve 96 at one end of a sleeve 95 for driving the workpiece head 100A (nut or bolt head). The sleeve hole 96 of the sleeve 95 is axially formed with a rectangular engaging portion 97 at the center of the inner wall of at least three sides, so that the rectangular engaging portions 97 can simultaneously face the surrounding surface of the workpiece head 100A. Face-to-face joint type.

The aforementioned anti-slip sleeve technology can drive the nut or bolt head and reduce the occurrence of slippage relative to the nut or bolt head slip, but there is still a defect, for example, the sleeve 95 A rectangular engaging portion 97 is axially formed at the center of the inner wall of at least three sides such that when it is operated, the workpiece head 100A (such as a nut or bolt head) is placed in the sleeve of the sleeve 95. When the hole 96 is inside, the corresponding planes need to be quite accurate, so that it can be placed and fit, which is cumbersome and time consuming. When one side of the workpiece head 100A has convex deformation, it is more difficult to insert and fit, or even impossible. The combination is a non-ideal design. Moreover, since the conventional anti-slip sleeve technology utilizes the occlusion of the three faces, when the surface of the workpiece head 100A is deformed, the occlusion rotation operation will be unstable, even during the application process. The situation in which China and the United States have separated from each other has taken place, and there is also a need to improve them. Therefore, how to improve the lack of use of the conventional sleeve structure should be an important direction for the industry or people with wisdom to solve and overcome.

Therefore, the inventors of the present invention have developed a solution in view of the shortcomings of the conventional sleeve technology and the fact that the structural design is not ideal, and it is hoped that a more convenient use can be developed. The structure of the meshing and rotating tool which is stable in operation and overcomes the problem of loss of the nut or the head of the bolt, serves the public and promotes the development of the industry, and the present invention has been produced by the concept of a long time.

The object of the present invention is to provide an intermeshing and rotating tool structure which can be used for rotating a nut or a bolt head or the like while being used for normally driving a nut or a bolt head. Loosening or tightening operations, thereby improving the overall convenience of use, economic efficiency and excellent market competitiveness.

Still another object of the present invention is to provide an intermeshing and rotating tool structure which can provide excellent convenience and simplicity in fitting a nut or bolt head and the like, and has an excellent octrusion driving force, and further Has excellent practicality.

The technical means adopted by the present invention to achieve the above object includes: a cylinder seat; a cylindrical slot provided in the cylinder seat, the cylinder slot includes three first groove faces, three second groove faces and six a third groove surface to form a peripheral side surface of the cylindrical groove, the third groove surface being located between the first groove surface and the second groove surface to form the first groove surface / the third groove surface / In the above configuration, the first groove surface has a curved surface, the second groove surface has a curved surface, and the second groove surface has a curved surface. Two sets of junctions are included, and the junctions of the two sets of joints are an obtuse angle greater than 90 degrees.

The technical means of the present invention further includes: a sleeve; a cylindrical slot is disposed in the sleeve, and the peripheral surface of the slot includes more than one first groove surface and more than one second groove surface.
