[Prior Art] A conventional sleeve can be seen in Fig. 1. Usually, a cylindrical body (20) is provided, one end of which is a set hole (21) for fixing the driving tool, and the other end is for the workpiece to be embedded. The drive sleeve hole (22), the aperture size and shape of the aperture is usually determined according to certain specifications, suitable for the transfer between different drive tools and various workpieces, and is convenient for use with various manual, pneumatic or electric tools. a magnetic sleeve of the prior art, wherein the magnetic member (25) is disposed perpendicular to the driving surface (23) of the driving sleeve hole (22); after the forging process of the sleeve (20) is completed, the process of the structure is completed. In another independent step, a magnetic member hole (24) extending perpendicularly from the inner driving surface (2) is drilled from the outer surface of the sleeve (2〇), and then the cylindrical magnetic member (10) is placed; It is generally cylindrical, so when drilling the aforementioned magnetic member hole (24), the operating surface is - the two sides of the downward buckling above the curved surface, which will greatly increase the difficulty of adding jade, and may increase by 0 plus Semi-finished loss rate. In addition, the wall surface of the hole gauze through the sleeve (10) may not be as strong as the strength of the sleeve structure and the magnetic member in the channel (24) is only in contact with the side of a workpiece, and the workpiece cannot be Berry is heavy. It is necessary to take advantage of the high-efficiency adsorption fixation effect, which relatively reduces the economic benefit per unit area of the magnetic member (2). π [New content] In order to solve the problem of inconvenience and insufficient adsorption force of the self-use magnetic sleeve mentioned above, this creation provides an improved magnetic member setting structure. 5 M307496 The sleeve structure of this creation includes: - the sleeve 'includes - a cylindrical body with a central through, the two ends of which are fixed for the driving tool. The hole reduction and the _ take the end for reading. The utility model is characterized in that: the driving surface is provided with a magnetic member which is covered with an elastic valve material, so that the polygonal workpiece is stably adsorbed in the driving sleeve hole during operation. The purpose and function of this creation can be achieved by providing a magnetic sleeve that temporarily absorbs and fixes the workpiece before and after the assembly is unloaded, and has the function of preventing the guard from falling and helping to position the guard before operation. " The purpose and effect of this creation is that the magnetic part of the material is applied to the driving surface of the boring hole, and the drilling process such as the conventional magnetic part passage can be eliminated. Not only does the "saving time" also eliminate the semi-finished loss that may occur during the tunnel drilling process, thus effectively reducing production costs. The three goals and functions of this creation can be achieved while providing the magnetic attraction function, but it can eliminate the damage of the sleeve body structure, and the purpose is to achieve the seam degree and service life of the sleeve. # The fourth purpose of this creation can be achieved. The position of the magnetic member is set relative to the center axis of the two parts of the sleeve, which can provide maximum adsorption and fixation to the workpiece with the smallest magnetic piece area. The five objectives and effects of this work can be achieved by providing effective magnetic attraction, which is to reduce the volume that must be used for the magnetic parts to meet the economic requirements of industrial production. The six objects and effects of the present invention are obtained by the elastic plastic material covered by the magnetic member, so that the recording member can be taken out from a sleeve through the user's urging force, and installed into another hole having the same driving sleeve. In this case, a single magnetic member can be used with a plurality of sleeves to achieve full economic benefits. 6 M307496 . [Embodiment] In order to achieve the above purposes and effects, the technical method adopted in the present case is as follows: · The magnetic sleeve of the sleeve is driven in the sleeve of the sleeve to make it accessible. The workpiece is effectively utilized for adsorption. As shown in the second, third and fourth figures, the improved sleeve structure of the present invention comprises a cylindrical body (10) which is vertically penetrated, and the two ends of the body (10) are respectively arranged holes (8) for fixing the driving tool and a driving sleeve hole (10) for inserting a workpiece at the other end of the cylinder; a magnetic member (10) is disposed in the driving sleeve hole (10). • The magnetic member (15) is made by taking a magnetic element αδυ, and coating the side and the end of the side with an elastic plastic body (10) by any of the conventional plastic forming techniques, so that the other end is flush Or a wire protruding from the elastic plastic (10); the miscellaneous and diameter of the dissolving plastic (151) is matched with the driving sleeve hole (12). Inserting the magnetic member (15) from the driving sleeve hole (10) of the sleeve (10) into the driving sleeve hole (10) with the opening of the exposed end of the magnetic member (151) relative to the opening of the driving sleeve hole (12); At this time, the plastic body (152) is compressed and rebounded toward the center due to the elasticity of the material, and is pushed against the driving sleeve hole ((2) of the driving surface (13), whereby the magnetic member ((5) can be It is fixed in the driving sleeve hole (10) without falling off. Since the structure of the present invention is to position the magnetic element (151) on the axial center position corresponding to the workpiece to be adsorbed, the maximum fixing effect of the unit magnetic attraction area can be exerted. Therefore, in the implementation of this creation, according to the size of the sleeve (10) and the suction force of the magnetic element (151), the minimum magnetic element (151) volume that achieves an effective adsorption force can be calculated to meet the economical requirements of industrial production. The fifth figure shows that the sleeve (1〇) of the present invention can be used with a driving tool (16), such as a ratchet wrench, to operate the workpiece (17), such as a bolt; when the sleeve ((8) is driven by the sleeve hole) (10) Set on the screw inspection (10) 7 M307496, above the 'because of the magnetic element (151) Protruding or at least flush with the edge of the plastic body (152), thereby being exposed to the drive sleeve hole (13), thereby contacting the bolt (17) therein. '· According to this 'the sleeve of the creation (1〇) The workpiece can be temporarily fixed and fixed after the workpiece is unloaded (17). (17) 'At the same time, it has the function of avoiding falling and helping to position before operation. In addition, since the plastic body (152) has elasticity, it is used as a When the magnetic member (15) is pushed to the driving sleeve hole (12) by the opposite direction in which the magnetic member (15) is disposed, that is, the set hole (丨丨) of the sleeve (10), The magnetic member (15) is unloaded from the sleeve (10) by the driving sleeve hole (12); and then the magnetic member (15) can be further installed in other sleeves (3 inches) having the same aperture, such as The sixth figure shows that a single magnetic member (15) can be used with a sleeve of the same drive aperture but different lengths to improve the flexibility and economy of the magnetic member (15). The best practical supplement is _, but the secret listener does not deviate from the spirit and the model of the case to make various changes in the form. The examples are only used to illustrate the case and are not intended to limit the scope of the case. All modifications or changes that are not in violation of the spirit of the case are within the scope of the patent application in this case.
