[0020] Example 2

[0021] This embodiment describes the fixing assembly in detail based on the embodiment 1, specifically:

[0022] See also Figure 1-3 The fixed component includes a telescopic member 7 installed in the connecting tube 1 and a driving unit for driving the telescopic member 7 to expand or contract. The telescopic member 7 includes a plurality of arc-shaped plates 8 arranged in a ring array and a telescopic rod 9 installed between adjacent arc-shaped plates 8. The plurality of arc-shaped plates 8 are concentrically arranged, wherein two telescopic rods 9 are provided, one end of the telescopic rod 9 is fixedly installed on the end face of one of the arc-shaped plates 8, and the other end is movably inserted on the end face of the other arc-shaped plate 8.

[0023] Specifically, the driving unit includes a movable disk 10, a connecting piece 11 and a push-pull module, the push-pull module includes multiple pairs of push-pull rods 13 and circular rings 12 symmetrically installed on both sides of the multiple pairs of push-pull rods 13, one end of the two push-pull rods 13 is hingedly installed on the arc plate 8, and the other end is hingedly installed on the side of the circular ring 12, one of the circular rings 12 is fixedly installed on the fixed disk 2, and the other circular ring 12 is movably arranged in the connecting tube 1, the movable disk 10 is movably sleeved on the connecting tube 1, and the inner ring of the movable disk 10 is connected to the circular ring 12 through multiple connecting pieces 11, and the side wall of the connecting tube 1 is also provided with side holes 14 for the sliding of the connecting piece 11, and the movable disk 10 is also provided with a plurality of connecting pieces 11. A plurality of screws 15 are installed in the row, and the screws 15 are threadedly installed on the fixed disk 2, and a fastening nut 16 adapted thereto is installed on the screw 15. Specifically, when it is necessary to fix the pipe inserted into the connecting pipe 1, it is only necessary to use a tool to screw the plurality of fastening nuts 16 on the side of the fixed disk 2. When the fastening nuts 16 rotate on the screws 15, the movable disk 10 can be driven toward the fixed disk 2. Under the action of the plurality of connecting parts 11, one of the rings 12 can be moved toward another ring 12. In this process, the plurality of pairs of push-pull rods 13 can push the plurality of arc plates 8 synchronously toward the direction of the pipe, so that the telescopic part 7 is contracted and the pipe is fixed.

[0024] Working principle and operation process: when connecting two pipes, first insert the two pipes from the socket until the pipe mouth of the pipe touches the annular opening 5 of the sealing sleeve 4, and then use a tool to screw the fastening nut 16 on the fixed disk 2. When the fastening nut 16 rotates on the screw 15, the movable disk 10 can be driven toward the fixed disk 2. Under the action of multiple connecting parts 11, one of the rings 12 can be moved toward the other ring 12. During this process, multiple pairs of push-pull rods 13 can push multiple arc plates 8 synchronously toward the direction of the pipe, causing the telescopic part 7 to contract, and realize the fixation of the pipe, and connect the two pipes together. Conversely, after screwing the fastening nut 16 in the opposite direction, the fixation of the pipe can be released, and the pipe can be pulled out from the connecting pipe 1 to realize the disassembly of the two pipes.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
