During actual installation, the staff first embeds the fixed block 205 of the fixed ring 207 into the cavity of the movable seat 101, and then fixes it with the pre-tightening bolt 105. Then, the movable seat 101 at one end is moved by the threaded rod 104 until the flanges 201 at both ends touch each other. By designing a thread on the outer diameter of the flange 201, it is matched with the external thread set in the fixed ring 207, so that the flange 201 rotates in the fixed ring 207. By rotating the flange 201 at one end, the engagement block 202 of the flange 201 at one end is engaged with the engagement strip 203 of the flange 201 at the other end. Finally, by adjusting the threaded rod 104, the movable seats 101 at both ends are tightly abutted against each other, so that the flanges 201 at both ends are connected.

[0026] By using the flange 201, the engaging block 202 and the engaging clip 203 in coordination, the two flanges 201 can be rotatably connected. When installing or disassembling, the two flanges 201 can be easily docked or separated by rotation without the need for excessive bolts and tools, thereby improving the convenience of operation. At the same time, through the design of the engaging block 202 and the engaging clip 203, the connection between the two flanges 201 can be made tighter and more stable, reducing loose connections caused by vibration or pressure changes.

[0027] Second embodiment:

[0028] like Figure 3-4 As shown, the movable seat 101 is provided with a cavity, a fixed block 205 is provided at the lower end of the fixed ring 207, both the fixed block 205 and the movable seat 101 are provided with positioning holes, and the fixed ring 207 is fixed to the movable seat 101 by a pre-tightening bolt 105.

[0037] The clamping block 103 is provided to provide a uniform and stable clamping force to prevent the subsequent rotation of the threaded rod 104, so that the movable seat 101 is more stable on the threaded rod 104. The stability of the movable seat 101 enables the flanges 201 at both ends to be firmly connected.

[0038] Working principle: During the actual installation, the staff first embeds the fixing block 205 provided by the fixing ring 207 into the cavity provided by the moving seat 101, and then fixes it with the pre-tightening bolt 105, and then moves the moving seat 101 at one end through the provided threaded rod 104 until the flanges 201 provided at both ends touch each other, and designs a thread on the outer diameter of the flange 201 to cooperate with the external thread provided in the fixing ring 207, so that the flange 201 rotates in the fixing ring 207, and the flange 201 at one end rotates, so that the engaging block 202 provided by the flange 201 at one end is engaged with the engaging clip 203 provided by the flange 201 at the other end, and finally the threaded rod 104 is adjusted to make the moving seats 101 at both ends tightly abut against each other, so that the flanges 201 at both ends are connected. When disassembly and replacement are required, first rotate the adjusting bolt 302, then rotate the flange 201 at one end, and finally rotate the handle 102 to separate the moving seats 101 at both ends.

[0039] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
