IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to an accessory for a screwdriver, and in particular to an innovative designer of a magnetic sleeve structure. '[Prior Art] =, the use of traditional screwdrivers (such as - word screwdriver, cross screwdriver) ': when people insert the screwdriver head into the sleeve of the screw head, due to the combination of = poor performance, often caused by the movement The problem of the screw falling affects the smoothness of the work; even with the magnetic design, it is only used for magnetization treatment at the head of the screwdriver. Not only is the suction force weak, but the magnetism is not durable, so the problem cannot be solved. Subhead = Supervisor = The creator of this singer has developed a kind of "anti-loose force magnetic sleeve". The structure type is shown in Fig. 1, and the pre-vehicle system is used. The magnetic sleeve plus portion 22 is arbitrarily slipped in the slot portion 11 and can be slid at a predetermined distance. However, such a conventional method has found that the following problems still exist in the experience. : Shixiong I?, sleeve 2 (3's slidable distance depends on the axial length of the yoke set on the screwdriver head. However, as far as the specific manufacturing surface is concerned, the 2 subhead Η) is the gold If the riding material is (4) into the groove portion (1), it must be achieved by a machining method such as cutting 7-knife radial feed turning, but the width of the card groove portion I can be made in a single feeding process. Phase:,: Limit (Note: the blade width of the general cutting blade is only 3~4 丽), so to meet the most basic slip distance requirement of the magnetic sleeve 20 (about 15 TM will have to go through multiple processing procedures) In order to achieve this, it is obvious that the 5 1302865 process lacks efficiency and costs are not in line with the above-mentioned reasons for better industrial utilization benefits, resulting in the magnetic final pass. Only 1 to 2 cm of the set 20 will be limited to the operation of the driver of the screwdriver. When working in the face cavity environment, the law is implemented, which in turn affects a large defect on the head of the screwdriver. How does slip-type magnetics develop a final range of the final range of the slippery maximum travel distance of 10 that can be considered by the relevant industry to be considered as a normal use of the rod? The goal of practical breakthrough and further, based on the relatively limited distance, has been 'so the magnetic inside, so that it has to be stretched into the slit or small magnetic sleeve to block without function, the actual design is, for the existence The innovative structure of the problem point, the real direction. The inventor has been engaged in the manufacture of related products for many years. The invention has been designed and carefully evaluated for practicality. In view of this, development and design experience, after the end It must be [inventive content] Set: the purpose is to provide a kind of slip-type magnetic 'I.
