[0021] In this embodiment, the push assembly drives the movable sleeve 104, causing the movable push rod 103 to press against the first set of flanges, thereby fixing the base plate 101. Then, by connecting the centering mandrel 105 to the through hole of the second set of flanges, the two sets of flanges are precisely aligned.
[0022] The mounting sleeve 102 is fixedly installed inside the base plate 101. The movable sleeve 104 is slidably installed inside the mounting sleeve 102 via the sliding assembly and the pushing assembly. The movable sleeve 104 is also provided with a mounting groove 106. The movable push rod 103 is rotatably installed on the outside of the movable sleeve 104 and located in the mounting groove 106. The centering mandrel 105 is slidably installed inside the movable sleeve 104. The base plate 101 has a T-shaped cross-section. The mounting sleeve 102 is welded inside the base plate 101. One end of the mounting sleeve 102 is threaded on the outside. The axes of the base plate 101, the mounting sleeve 102, and the movable sleeve 104 coincide. The number of mounting grooves 106 is the same as the number of... There are three sets of movable push rods 103, arranged in a ring around the outside of the movable sleeve 104. The movable push rods 103 are rotatably engaged with the mounting groove 106 via a damping shaft. After the base plate 101 is installed on the first set of flanges, the movable sleeve 104 is pushed to the other side of the first set of flanges by the cooperation of the sliding assembly. Then, the movable push rods 103 are pulled out of the mounting groove 106 and kept in an outwardly expanded state. The movable sleeve 104 is reset by the pushing assembly, so that the movable push rods 103 press against the first set of flanges, thereby fixing the base plate 101. Then, by pushing the centering mandrel 105, the centering mandrel 105 passes through the through hole of the second set of flanges, thereby achieving precise alignment of the two sets of flanges.
[0023] Secondly, the limiting slide bar 107 is fixedly installed inside the mounting sleeve 102; the sliding groove 108 is disposed outside the movable sleeve 104, and the limiting slide bar 107 and the sliding groove 108 are slidably engaged. The limiting slide bar 107 is arranged in a ring inside the mounting sleeve 102. The limiting slide bar 107 has a square structure and is adapted to the structure of the sliding groove 108. Through the sliding engagement of the limiting slide bar 107 and the sliding groove 108, a guiding function is provided for the movement of the movable sleeve 104 within the mounting sleeve 102.

[0025] Furthermore, the anti-slip protrusion 111 is fixedly installed on the push ring 110. The anti-slip protrusion 111 is arranged in a ring on the outside of the push ring 110. The anti-slip protrusion 111 provides an anti-slip function when the push ring 110 is rotated.
[0026] Finally, the guide portion 112 is disposed at the end of the centering mandrel 105. The guide portion 112 has a tapered structure. With the cooperation of the guide portion 112, it is convenient to pass the centering mandrel 105 through the through hole of the flange to be connected.
[0027] In this embodiment, during use, the base plate 101 is passed through the through hole of the first set of flanges. Then, through the sliding engagement of the slide groove 108 and the limiting slide bar 107, the movable sleeve 104 is pushed, causing it to move within the mounting sleeve 102. This allows the movable push rod 103 within the mounting groove 106 to reach the other side of the first set of flanges. Subsequently, the movable push rods 103 within the mounting grooves 106 are pushed outwards, keeping them in an expanded state. Then, by rotating the push ring 110, the push ring 110 moves towards the fixed ring 109 through its threaded engagement with the mounting sleeve 102, pushing the fixed ring 109. This causes the fixed ring 109 to reset the movable sleeve 104, and the movable push rod 103 abuts against the first set of flanges, thus fixing the entire device onto the first set of flanges. Then, the centering mandrel 105 inside the movable sleeve 104 is passed through the through hole of the second set of flanges, thereby achieving centering of the two sets of flanges. After connection, the entire device can be removed, thus avoiding manual visual alignment and the need for repeated adjustments during the connection process.
