New description: [New technical field] The new type is related to a kind of sleeve, especially a sleeve that is more suitable for use. [Prior Art] Fig. 1 shows a conventional sleeve-type sleeve 1 having a drive hole π having a non-circular cross section and a driven hole 12 which is driven by a wrench ι〇ι The driven hole 12 can be driven - screw 1 () 2. However, when the sleeve is used for a long time or is subjected to too much pressure, the turning portion 121 of the outer peripheral surface of the driven hole 12 may be cracked due to material fatigue. Even when the sleeve i is applied to an automated system and is operated in large quantities, the sleeve i needs to be replaced every few days, with a lack of structural strength. Right to improve this deficiency, Φ Φ. The sleeve is made of a more responsible material in a private manner' but this creates a costly manufacturing defect. [New content] - The structural strength is sufficient and the driving tool and a fixed element receiving ring are made of metal. This drive unit is suitable for the inner peripheral surface of the drive. The slave-non-circular driven inner surface is formed of a relatively first metal and is sheathed. Therefore, the purpose of the present invention is to provide a sleeve which can save manufacturing costs. Thus, the 'new sleeve is adapted to be connected to a piece' and includes a receiving ring and a set of rings, and includes a driving portion and a driven portion driven by the driving tool and having a non-circular shape The moving portion is adapted to drive the fixing component, and has a circumferential surface and a swaying outer peripheral surface, and the driven outer peripheral card is further combined with a brother. The sleeve ring is made of 3 the driven outer peripheral surface and is threaded to the second clamping section. Α β The function of this new type lies in the reinforcement of the socket, so that the driven ρ is increased/increase in use, which is not easily damaged. The structural strength of the sleeve is strong and durable. [Embodiment]

The fixing element can be a fixing element such as a screw or a nut. The sleeve comprises a receiving ring 3 and a socket ring 4. 2, 3, and 4, the receiving ring 3 is made of metal, and includes a connecting portion-driven portion 31 and a driven portion 321 driving portion 31 for driving the driving tool, and has (4) Driving the inner peripheral surface of the shape and driving the outer peripheral surface 312. The driving inner circumference φ 311 defines a driving hole 313 having a quadrangular cross section, and the driving inner peripheral surface 311 forms two engaging holes 314 extending to the driving outer peripheral surface 312. The driven portion 32 is adapted to drive the fixing member, and has a non-circular driven inner circumferential surface 321 , a driven outer circumferential surface 322 , and a connecting the driven inner circumferential surface 321 and the driven outer circumferential surface 322 . The slave side is self-reliant. The driven inner peripheral surface 32 defines a driven hole 329 having a hexagonal cross section, and the driven outer peripheral surface 322 has a first first clamping section 324 and a second clamping section milk, a self The inner circumference of the first clamping section 324 is newly expanded toward the second clamping section 325 (the protruding cone cylinder section 326, the connecting driven cone section is similar to the second clamping & 325 follower The limiting section 327, and extending from the outer periphery of the first clamping section to the driven section 328 of the driven end surface 323. The socket % 4 is made of a metal different from the receiving ring 3, including - a sleeve inner circumferential surface 套 disposed on the driven outer circumference δ 322, an open end surface 42 adjacent to the driven end surface 323, and an abutting end surface 43 opposite the open end surface 42 and abutting the second clamping portion 325 The sleeve inner circumferential surface 41 has a sleeve tapered cone section 412 which is gradually extended and extended from the inner circumference of the opposite side of the clamping section 411 against the first clamping section 324, from the sleeve a sleeve limiting segment 413 extending toward the abutting surface 43 , a sleeve extending from the sleeve limiting portion 413 to the guiding portion 414 of the abutting end surface 43 , and - from the pair of cards The outer circumference of the segment extends to the sleeve portion of the open end surface 42. The sleeve cone is mounted on the driven cone portion 326, and the sleeve limiting portion (1) is sleeved on the driven limit. In the segment 327, the sleeve portion 415 is sleeved on the driven segment 328. The length of the first card segment 324 and the pair of card segments 411 are between 公5 mm and 0.1 mm. The clamping structure of the section 324, the second clamping section 325, the pair of card sections 411, and the abutting end surface 43, when assembled, the socket ring 4 can be directly knocked in from the right side to the left side to have a good combination effect. The sleeve of the present invention has the following effects: 1. The reinforcement of the socket ring 4 reduces the amount of deformation of the driven inner circumferential surface 321 during use, and reduces the turning point of the driven inner circumferential surface 321 The sleeve is structurally strong and durable due to the fatigue of the M380199. The 亥°海第+段段324, the second card section 325, the card section 411, and the end face 43 , the following formula, can completely maintain the color of the outer peripheral surface 4 of the socket ring, and, the text path is complete 'the color of the socket 4 and the color of the receiving ring 3 make the sleeve produce The color effect, or the surface of the sleeve ring 4 is textured, so that the sleeve is more beautiful. 2. The sleeve ring 4 can be made of more expensive and stronger metal, so that even if the receiving ring 3 is relatively weak Made with cheap materials, it can still achieve good strength 'and fatigue resistance L. It saves the cost of manufacturing. The above-mentioned ones are only the preferred embodiment of the present invention, and do not commit this limitation. The scope, that is, the simple equivalent changes and modifications made by the company in accordance with the scope of the new patent application and the new description are still within the scope of this new patent.
