Description

1248851 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a structure of a non-circular sleeve sleeve, and more particularly to a socket wrench or a variety of open-end wrenches or spanner wrenches. Sleeve structure. [Prior Art] According to the conventional conventional sleeve, it is used in combination with a socket wrench and can be used for locking or disassembling a screw. It also requires only a socket wrench and a sleeve of various sizes. It can be locked and unloaded in various sizes of screws, which is extremely convenient to use and is widely used in the industry. However, although it is highly replaceable, it is only suitable for a socket wrench. When the socket wrench is lacking on the hand, the sleeve is not available, or when it is often used, it is often not necessary to use it in a narrow space. After the combination of the socket wrench and the sleeve, the height must be increased, which often results in the inability to lock and unload the screw directly in a small space, and the surrounding parts must be removed first. Homework; however, although it can finally complete its work, it also increases the workload of the user invisibly. On the other hand, the time of its work is also invisibly increased. In this era of time and second, there is a great improvement. . For this, please refer to Annex 1 ("NESTED EXPANSIBLE SOCK ET"), which is set to a circular shape on the outer edge of the upper end of the sleeve of Figure 1 and Figure 2. The outer edge of the upper end of the sleeve of Figure 3 to Figure 6 is set to a hexagonal flat cut surface, and Figures 7 to 8 will be provided with a two-layer hexagonal flat cut surface; when the sleeve is used, if it is in a narrow space, You don’t have to spend a lot of time to eliminate the surrounding

1248851 V. Inventories (2) Obstacles can only be used for work, or when there is no socket wrench on the side, and there is no need to work hard. As long as there is a hole wrench or a spanner wrench that fits the size, it can be used as a cover. The temporary replacement of the barrel wrench and the successful completion of its work. However, although the design of this patent is to improve the socket wrench as a "non-essential tool" for the sleeve, it is necessary to have an open-end wrench or a spanner wrench that fits the size of the outer edge of the sleeve. In order to carry out the work, although it has been expanded to be convenient to use, at the same time, it is inconvenient to find a wrench or a wrench with the same size, which may cause considerable trouble for the user, otherwise the work cannot be completed. And the figure VII to VIII, because it has a double-sided hexagonal flat surface, it has more space, so that it can not be used smoothly in a narrow space, so on the whole, there is a lack of existence. Therefore, in view of the unsatisfactory advantages of the above-mentioned conventional socket wrenches, the creator deeply feels that it is necessary for further research and development, and is researched and improved by the experience of designing and manufacturing such products. After a long period of experiment and revision And designing this creation, because of the structure, try to adopt a more simplistic design, which promotes the advantages of compact components and reliable functions, and can achieve the expected SUMMARY OF THE INVENTION The present invention is directed to a non-circular sleeve sleeve structure. The structure of the non-circular sleeve mainly includes a sleeve body having a sleeve for providing a screw. The other end is formed with a connecting portion that communicates with the receiving portion, and the connecting portion is used for connecting the socket wrench; and the connecting portion is located at the connecting portion

Page 6 1248851 V. Description of invention (3) The outer edge is provided with a set of joints, which are formed with two corresponding arc-shaped cut surfaces, which can be set by tools such as open-end wrenches or open-cut wrenches; The arc cut surface has a distance ranging from a maximum diameter to a minimum diameter, so that it can be combined with an open-end wrench or a spanner wrench to have several sections, each section can be With the maximum diameter of an open-end wrench or a spanner wrench, it is stuck in the section to achieve the effect of pulling the sleeve. As described above, the present invention still has a sleeve that can be used with a socket wrench, and is used in conjunction with a socket wrench, and if there is no socket wrench in the hand, or in a narrow space, there is no suitable sleeve. In the case of a wrench, an open-end wrench or a wrench can be used instead. In addition, the tool can be selected from a single size, and various sizes can be applied without worrying about the size of the hand. The inconvenience and trouble caused by the use of tools is actually an invention design with industrial value. [Method for Carrying out the Invention] The present invention relates to a structure of a non-circular sleeve sleeve, which is shown in the first figure, which is a preferred embodiment of the present invention. The structure mainly comprises a sleeve body (1〇), and an upper end of the sleeve body (10) is provided with an engaging portion (1 1 ), which is formed as a square hole, which can be pulled by the trigger sleeve; The accommodating portion (1 2 ) at the lower end of the connecting portion (1 1 ) is provided with a hexagonal shape for the screw to be received therein; and the sleeve body (10) The outer edge of the upper end is provided with a set of joints (1 3 ), which are two corresponding arc cuts.

1248851 V. INSTRUCTIONS (4) Face (1 4 ) is available for open-end wrench (20) or open-hand wrench, and this figure uses an open-end wrench as an example; the circular cut surface (1 4 ), please refer to the second and third figures, which are between the largest diameter and the smallest diameter, and have different diameters and sizes, which can be used for different sizes of open-end wrenches (20) or open spanners. The sleeve body (10) is divided into a plurality of sections, and each section is such that the maximum diameter of the spanner wrench (20) or the spanner wrench is engaged in the section, and the trigger sleeve is achieved. For example, if the gauge has a diameter of A (as shown in the second figure), it will be stuck on one of the circular cut planes (1 4 ), or if its caliber is B~E and other specifications. (As shown in the third picture), it will also be stuck in other different sections, so that it can effectively achieve the purpose of the trigger. When used, please refer to the fourth embodiment, which is a preferred embodiment of the present invention, which only needs to have a wrench on the hand between the maximum and minimum diameters of the circular cut surface (1 4 ), the open end wrench (2 0 ) or the open wrench can be clamped by the circular cut surface (1 4 ), and then used for screwing work. As described above, in view of the preferred embodiment of the present invention, it can be seen that the sleeve structure of the present invention is not missing from the conventional sleeve structure, and retains all the functions of the conventional sleeve, and further simplifies the conventional structure. In order to make the reviewing committee more aware of the efficacy and value that can be achieved by the present invention, the above arguments are discussed: 1. The present invention still has a sleeve that can be used with a socket wrench for use; If it can be used with a socket wrench, if there is no socket wrench in the hand, or in a narrow space, the socket wrench is not applicable.
