New description: [New technical field] A type of expander structure, especially a simple operation, which allows the end of the pipe to expand and be extruded into a flat shape to facilitate the nut lock when the pipe is connected. Closed and kept airtight after connection. And expander structures that can be used for the processing of different round diameter pipe fittings. [Prior Art] Press; generally for the transportation of gas, etc., due to the convenience of connection, usually as shown in the first figure, the nut 1 is placed on the pipe 2, and the pipe 2 is given by the nut 1 The lock is fixed. However, since the end portion 2 1 of the general pipe member 2 has an arc shape, it is not only convenient to process but also has a poor gas density when connected. Therefore, as shown in the second figure, if the end portion 21 of the tubular member 2 is processed into a flat shape, the nut 1 is more convenient, quicker, and more airtight when it is locked. In view of this, the applicant has been practicing the business for many years. After continuous research and experimentation, Yan Mengsheng improved a pipe expander structure, which made it easier to connect the pipe fittings and was more airtight after joining. effect. [New content] The main purpose of this creation is to provide a pipe expander structure, which allows the pipe to be expanded and extruded into a flat shape by simple operation, so as to facilitate the locking of the nut when the pipe is connected. It is also airtight after connection and can be applied to the processing of different round diameter pipe fittings. The foregoing expander structure includes a base and a hammer that is worn on the base. Wherein, one end of the base is provided with a through hole at the center for the hammer to be pierced and can slide along the through hole, and the other end is configured to be able to twist the upper and lower cover bodies, and the upper and lower covers are The bodies are respectively provided with the embedded grooves, and the fixed pieces are respectively locked in the embedded grooves, and the protrusions are arranged at the inner edge end of the positioning piece 3. When used, the end of the pipe member is placed on the positioning piece so that the end portion is stuck on the protruding piece of the positioning piece, and the sliding of the pipe member is formed by the sliding of the hammer, so that the end portion of the pipe member is expanded and pressed to form a flat shape. In order to facilitate the connection of the nut when the pipe is connected, and to maintain airtight after the connection. And by the replacement of the positioning piece and the hammer, it is suitable for the processing of pipe fittings with different round diameters. In the above-described expander structure, the hammer system includes a tapping portion and a sliding portion extending from the striking portion to a smaller diameter, and the base is provided with a retaining ring for allowing the hammer to slide The retaining ring stops against the tapping portion to prevent the hammer from slipping out. [Embodiment] Please refer to the third and fourth figures at the same time, and in conjunction with the fifth figure, this is a two-dimensional and three-dimensional exploded view, and a cross-sectional view. As shown in the figure, the creation system includes a base 3 and a hammer 4 which is worn on the base 3. In this embodiment, the base 3 can be set to have a different shape. In the present embodiment, the base is formed in a hexagonal shape, and may be in the shape of a square or a semicircle, and one end thereof is provided with a through hole in the center, and the through hole is formed in the through hole. 3 1 is provided with a retaining ring 3 1 1 for the impact 4 to be worn and can be slid along the through hole 3, and the other end of the base 3 is set as an upper cover 3 2 and a lower cover 3 3 The lower cover bodies 3^2, 3 3 are connected to each other by the lugs 3 2 1 and 3 3 1 to form a foldable shape. The upper and lower cover bodies 32, 3 3 are respectively provided with semi-circular shaped grooves 3 2 2, 3 3 2 ', and the fixing holes 3 2 3, 3 3 3 are respectively provided in the septic grooves 3 2 2, 3 3 2; ^ Two positioning pieces 3 4, 3 5 are provided with protrusions 34 1 , 3 5 1 at the inner edge ends of the positioning pieces 3 4, 3 5 and the protrusions 3 4 1 , 3 5 1 are set to The lower side is slanted, and the surface is provided with through holes 3 4 2, 3 5 2, so that the two positioning pieces 34, 35 are respectively inserted through the holes 342, 352 through the bolts 36, 37, and are fixed in the slots. The fixing holes 323 and 333 of the 322 and 332 fix the clamping pieces 34 and 35 to the fitting grooves 322 and 332. The hammer 4 includes the striking portion 4 1 and is extended by the striking portion 4 i. The sliding portion 42 of the second portion is provided with an arc-shaped projection 4 1 1 in the cross section of the striking portion 4 1 , and a screw hole is provided in the sliding portion 42 to make the sliding portion 4 2 from the inside. After passing through the through hole 3 1 of the base 3, the grip portion 4 is provided with a screw portion 4 3 and is locked and fixed, so that when the hammer 4 slides along the through hole 3, the core can be blocked. 3 1 1 constitutes a stop for the striking portion 4 i to prevent the hammer 4 from slipping outward; the expander structure is constructed by the combination of the members. When the lid 3 of the base 3 is opened, the end of the tube is placed on the positioning piece 35, and the end is clamped to the protrusion of the positioning piece 35, after positioning. Then, the upper cover body 3 2 is covered, and the sliding of the key member 4 is formed by sliding back and forth to form a tapping of the pipe member, so that the end portion of the pipe member is pressed and formed into a flat state, and the nut of the pipe joint is connected when the pipe is connected. And it is kept airtight after connection. And by the replacement of the different size of the positioning piece 3 4, 3 5 and the hammer 4, it is suitable for the pipe processing of different round diameters. Please refer to the sixth and seventh figures at the same time, which is a diagram of the use of this creation. Please cooperate with the fourth picture. As shown in the figure, when the creation is used, the cover 3 of the base 3 is first opened, and the end of the tube is placed on the positioning piece 3 5 to make the end thereof. The card is placed at the protrusion 3 5 定位 of the positioning piece 35, and the protrusion is slightly extended. After the tubular member 2 is positioned, the upper cover member 3 2 is closed, so that the end portion of the tubular member 2 will be completely surrounded and restricted by the protrusions 3 4 1 and 3 5 1 without being easily slipped. The tapping of the pipe member 2 by the back and forth sliding of the keystroke 4 causes the tapping portion 4 1 to press the end of the pipe member 2, and the projection 4丄i expands the end portion, thereby causing the end portion of the pipe member 2 Expanded and extruded to form a flat state (as shown in the second figure) to facilitate the locking of the nut when the tube 2 is connected, and to maintain airtightness after the connection. When the tube member 2 of different round diameters is used in the present invention, since the positioning pieces 34, 35 and the hammer 4 are detachable, when used in the tube 2 of different circular diameters, the user can mosquito The bit pieces 3 4, 3 5 are replaced by larger or smaller semi-circular diameters by the disassembly and assembly of the bolts 3 6 and 3 7 , and the striking portion 4 of the M 4 can be expanded by the same operation process. The pipe can be improved by replacing the corresponding one with a larger or smaller diameter, which is suitable for the processing value of the pipe member 2 with different round diameters. The embodiments, but not limited to the above embodiments, are merely illustrative of the scope of the preferred creations of the creations, and where the modifications are made, the meanings are not deviated from the spirit of the creation. . In summary, the creation of the machine is provided with a positioning piece, and the hammer can be moved along the machine base to form a pipe expander, so that the pipe piece is expanded and extruded by simple operation. The fortune 'supplied to the nut lock when the pipe joints are connected, and is kept airtight after the connection, and can be applied to the processing of different round diameter pipe fittings. For a practical design, it is a novelty creation. If you apply for a patent in accordance with the law, the Bureau of Prayer will review it and grant the patent as soon as possible.
