[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-5 A stainless steel seamless pipe comprises a seamless pipe 1 and a seamless pipe 2 5: the outer side of the seamless pipe 1 is fixedly connected with a fixing ring 2, the outer side of the seamless pipe 2 5 is fixedly connected with a fixing ring 2 3, and the outer sides of the fixing ring 2 and the fixing ring 2 3 are provided with an installation unit 4, wherein the installation unit 4 facilitates the rapid connection of the seamless pipe 1 and the seamless pipe 2 5 together.

[0025] The mounting unit 4 includes a plurality of positioning cylinders 407, which are fixedly connected to the right side of the fixing ring 2. Two stabilizing rods 413 are arranged on the outer side of the positioning cylinder 407. The outer sides of the two stabilizing rods 413 are provided with rectangular grooves 414. A connecting plate 415 is rotatably connected to the inner side of the rectangular groove 414. A rotating block 416 is rotatably connected to the outer side of the left end of the connecting plate 415. A moving plate 409 is fixedly connected to the left side of the rotating block 416. A fixing rod 405 is fixedly connected to the left side of the moving plate 409. A control block 404 is fixedly connected to the left end of the fixing rod 405. A spring 406 is fixedly connected between the control block 404 and the positioning cylinder 407. A plurality of moving grooves 401 are arranged on the right side of the fixing ring 2. A plurality of slide grooves 402 are provided, and a control rod 403 is slidably connected to the inner side of the slide groove 402. The upper and lower ends of the control rod 403 are both arranged in an arc-shaped structure. The left side of the control block 404 is arranged in an arc-shaped structure. A plurality of positioning grooves 408 are provided on the left side of the fixed ring 23. Two stabilizing grooves 412 are provided on the inner side of the positioning groove 408. A swivel 411 is provided on the outer side of the fixed ring 23. Thread grooves 410 are provided on the outer sides of the fixed ring 2 and the fixed ring 23. An internal thread is provided on the inner side of the swivel 411. The fixed rod 405 is slidably connected to the positioning cylinder 407. The connecting plate 415 is arranged in an inclined structure. The positioning cylinder 407 is adapted to the positioning groove 408. The stabilizing rod 413 is adapted to the stabilizing groove 412. The movable plate 414 is provided with a plurality of positioning grooves 408 on the left side. 09 is slidably connected with the positioning cylinder 407. When installing, first insert multiple positioning cylinders 407 into the corresponding positioning grooves 408 to preliminarily install the fixing ring 1 2 and the fixing ring 2 3, and then rotate the rotating ring 411 to move the rotating ring 411 to the left. When the rotating ring 411 moves, the control rod 403 is squeezed to drop. Since the lower part of the control rod 403 is an arc-shaped structure, the lower part of the control rod 403 squeezes the control block 404, and the control block 404 drives the fixing rod 405 to move right. The fixing rod 405 pushes the moving plate 409 to move, and the moving plate 409 drives the connecting plate 415 to rotate. The connecting plate 415 drives the stabilizing rod 413 to move. Since the connecting plates 415 on both sides are arranged in an inclined symmetrical structure, the stabilizing rods 413 on both sides move toward the stabilizing rod 413. The swivel 411 is threadedly connected to the fixing ring 1 2 and the fixing ring 2 3, so that the swivel 411 limits the fixing ring 1 2 and the fixing ring 2 3, thereby increasing the tightness of the installation and quickly installing the seamless pipe 1 and the seamless pipe 2 5. When disassembling, the swivel 411 is rotated in the opposite direction to separate the swivel 411 from the control rod 403. At this time, since the spring 406 is compressed, the elastic force of the spring 406 facilitates the separation of the control rod 403, so that the stabilizing rod 413 is separated from the stabilizing groove 412, and then the fixing ring 1 2 and the fixing ring 2 3 are directly separated to complete the disassembly, which is simple to operate.

[0026] Working principle: When in use, the staff first inserts the positioning cylinder 407 into the positioning groove 408, and then rotates the swivel 411. The swivel 411 squeezes the control rod 403. Under the action of the control block 404 and the fixed rod 405, it is easy to control the movement of the movable plate 409. Under the action of the connecting plate 415, it is easy to move the stabilizing rods 413 on both sides into the stabilizing groove 412, so that the fixed ring 1 2 and the fixed ring 2 3 are installed more tightly, and the swivel 411 is used to limit the seamless pipe 1 and the seamless pipe 2 5 to be quickly installed together. When disassembling, the swivel 411 is rotated in the opposite direction. Under the action of the elastic force of the spring 406, it is easy to separate the stabilizing rod 413 from the stabilizing groove 412, so that the seamless pipe 1 and the seamless pipe 2 5 can be quickly separated.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
