Description

Meshing rotary tool improved structure

The present invention relates to a rotary tool, and more particularly to an improved structure of an intermeshing rotary tool 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 hair. There is a missing condition in which the nut or the bolt head slips, but there is still a defect thereof. For example, 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 when When the working head 100A (such as a nut or a bolt head) is placed in the sleeve hole 96 of the sleeve 95, the corresponding planes need to be quite accurate, so that the sleeves are placed in a nested manner, which is troublesome. Time-consuming, when one side of the workpiece head 100A has a convex deformation, it is more difficult to fit in and out, and it is even impossible to fit, which is not an 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 creator of this creator has developed a solution based on the shortcomings of the conventional sleeve technology and the unsatisfactory design of its structure design, hoping to develop a more convenient, The improved structure of the meshing and rotating tools that overcomes the problem of the stability of the nut and the loss of the head of the nut or the bolt to serve the public and promote the development of the industry.

The purpose of the present invention is to provide an improved structure of the meshing rotary tool, which can be used in the case of normally driving a nut or a bolt head, and can be worn or damaged in the state of the nut or bolt head corner. Loosen or tighten the operation to improve the overall convenience of use, economic benefits and excellent market competitiveness.
