Description of the Invention: [Technical Field] The present invention mainly discloses an inflation joint, and in particular, an inflation joint that utilizes head expansion and contraction to apply to different tire nozzles. [Prior Art] In recent years, due to the general improvement of living standards in countries all over the world, we also pay more attention to leisure life. With the implementation of the two-day break, people have increased their leisure time. Therefore, they use these holidays to engage in leisure and tourism. The number of people in sports is increasing rapidly, and the most suitable tool for outdoor leisure activities is bicycles. Therefore, the pump in the bicycle is an indispensable item for the cyclist. According to the attachment of the Republic of China Patent No. 3488〇9, “Simplified Inflator Valve Switching Structure” patent case, when two different specifications of the air nozzle inner plug are respectively inserted into the open end of the double-opening cylinder, And it is covered by the right and left sides of the fitter's work panel, and it is a simple-type air pump switch structure. The prior art gas nozzle is a double-opening structure with left and right openings, one for the type of nozzle, and the other for the American nozzle, the conventional structure needs to be used for two nozzles and two switches for different nozzles. Effect. However, the prior art has a complicated structure and high manufacturing cost. Furthermore, the head of the double-opening pump has a large head, which makes the head easily broken or dropped to the ground and damaged, causing the gas nozzle to leak and need to gamble to buy a new nozzle. Burden, for the above problems, it is necessary to be improved in 201107602. The present inventors have invented a drawback that the above-mentioned conventional structure can be overcome in view of the above-mentioned conventional structure and can be applied to the telescopic inflation joint structure of different nozzles. [Summary of the Invention] This issue of the Japanese-style turn-to-red technology asks for the escape of the technology, and provides a telescopic inflatable joint that can be applied to different nozzles. The main purpose of the handle is to use the top tube to feed the chamber, and to selectively work on the second joint, so that the pump can achieve the fast catch and switch dual-gas effect, not only the knot The city shrinks the volume of the pump head. A secondary object of the present invention is that the components of the head of the air head are simple, and the head of the pump is used for telescopic expansion of the nozzle, and the use of a switch is not required, which can effectively reduce the production cost. Other objects, advantages and novel features of the invention will be apparent from the description and appended claims. [Embodiment] The technology, the means and the functions thereof used in the present invention are described in detail with reference to the drawings, and the following is only for the purpose of the application, and is not applicable to the patent application. Structural limitations. Referring to the drawings - and FIG. 2, the present invention is applicable to a stereoscopic map and a three-dimensional touch of a telescopic inflatable joint of different nozzles. The invention includes a top-of-the-line 201107602 heart tube 20 and a tube body 30. The top tube 20 is inserted into the air tube 40 of the inflator. In the present embodiment, the air tube 40 is a hose, and the tube 30 is sleeved with the top tube 20, and the tube 30 can be selectively connected to the top center. The tube 20 is provided, and the tube body 30 is connected to the tire nozzle. Referring to FIG. 3 at the same time, a cross-sectional view of a telescopic air-filled joint of different nozzles can be applied to the present invention. The core tube 20 has a first end 201 and a second end 202. The core tube 20 has an air passage 21 therein. The air passage 21 communicates with the two ends 201, 202 of the core tube 20, and the air passage 21 is The first end 201 of the core tube 20 has a lateral through hole 211 communicating with the outside of the first end 201 of the core tube 20. The outer periphery of the two ends 201, 202 of the core tube 20 is provided with a sliding portion 22, and the sliding portion 22 is sleeved with two O-rings 221. The first end 201 of the core tube 20 is provided with a top portion 23 and a joint portion 24 formed at an end of the first end 201 of the top core tube 20 to open the ejector pin of the tire nozzle. 24 is formed on the outer circumference of the core tube 20, and the joint portion 24 is located between the top portion 23 and the sliding portion 22. The second end 202 of the core tube 20 is provided with a connecting portion 25 that is inserted into the air tube 40, and the air passage 21 of the top tube 20 communicates with the inside of the air receiving portion 25 and the air tube 40. The tube body 30 has a first end 301 and a second end 302. The first end 301 of the tube body 30 has a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is adjacent to the end of the first end 301 of the tubular body 30. The first connecting portion 31 can be screwed to the thread of the American air nozzle, and the second connecting portion 32 can be screwed to the French air nozzle. a thread of the second portion 201107602 is smaller than the aperture of the first connecting portion 31, and a ring groove is disposed between the first connecting portion 31 and the second connecting portion 32 in the tube 30. The ring groove 33 is provided with a seal ring 331 which is sufficient for the airtight effect of the tire nozzle to abut against the pipe body 3 〇. The second end 302 of the shoulder b body 30 has an accommodating space %, and the second connecting portion 32 and the accommodating space % are axially connected, and the second connecting portion 32 is located at the first connection Between the portion 31 and the accommodating space 34. The aperture of the accommodating space 34 is larger than the aperture of the second connecting portion, so that the accommodating space 34 is smaller than the rim 3 of the second connecting portion 32. The accommodating space 34 is opposite to the second connecting portion. A groove 342 is provided for providing a tamper-proof milk. The accommodating space 34 of the clothing 22J= is slidably disposed on the sliding portion s of the top core tube 2 〜. The inner wall surface of the valley space 34 is airtight against the 0-ring 221 of the sliding portion 22 to prevent gas external steam. . And: ΛΕ 00 ^ I .. sliding of the person U & 2〇 The top core tube 2 is prevented by the anti-off ring 35 of the == 3 of the tube body. Tian A s basket do brother's second end 3 〇 2 out. . In the fourth connection portion of the tubular body 30, the second connecting portion 32 of the tubular body 30 can be combined with the first edge 2〇1 of the screw core tube 20 to support the sliding body 3 of the top tube 2〇. The gas nozzle is connected to the pipe body (4) - the connection: the outer edge of the = nozzle is pressed against the seal ring and the pipe 2. The joint part (4) is locked in the pipe body 3: ^ The top part 23 extends into the pipe body 3 〇 弟 - 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 连接 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The thimble' makes the pump air tube 40 201107602 body from the air tube of the top tube 2 _ gas operation. Referring to FIG. 5 and FIG. 6 through the through hole 211, when the connecting portion 32 of the top tube 2 is not screwed, the tube body can be axially relatively slipped 24 The anti-detachment ring 35 of the sliding portion 'body 3' of the top core tube 20 can stop the nozzle. = Figure 6 shows 'At this time, the neck of the French nozzle of the pump head is pressed against the second connecting portion 32 of the second screw, and the top is opened, so that the top = 23 will be poured into the top of the core tube 20 The French air nozzle is inflated as the water of the s 2 这. This 21 through the through hole can be summarized as described above. The present invention has the following borrowing portion for the inflating and the selective screwing. This second connection can reduce the volume of the pump head early. . 2.
