[0041] There are scale lines on the outer surface of the fixing rod 22, and the fixing rod 22 passes through the limiting ring 21 and extends outward;

[0042] The limiting ring 21 can move on the outer surface of the fixing rod 22, and the fixing rod 22 can keep the limiting ring 21 in a straight line state;

[0043] The first telescopic spring 26 is located inside the other end of the fixed rod 22, and the movable column 25 is a T-shaped structure;

[0044] When the movable column 25 moves to the inside of the fixed rod 22, the first telescopic spring 26 is compressed;

[0045] Working principle: When the drain pipe is positioned and installed, the buckle body 11 is placed outside the drain pipe, and a moving force is applied to the limit ring 21, so that the buckle body 11 moves along the fixed rod 22 driven by the limit ring 21. Multiple buckle bodies 11 can maintain a straight line along the direction of the fixed rod 22, and then the spacing between the buckle bodies 11 is measured according to the scale line on the upper end of the fixed rod 22. When multiple groups of buckle bodies 11 are needed, the movable column 25 can be pressed downward to move the movable column 25 inward and drive the first telescopic spring 26 to be compressed. At this time, it is moved to the inside of the slot 23 at one end of another group of fixed rods 22. The movable column 25 moves outward to the inside of the fixed slot 24 under the elastic force of the first telescopic spring 26, thereby completing the extension of the fixed rod 22.

[0046] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0047] A support assembly, the support assembly includes a support tube 31, a second telescopic spring 32, a movable tube 33 and a top plate 34;

[0051] The top plate 34 can move inside the buckle body 11, and when the top plate 34 moves outward, the movable tube 33 can be driven to move outward;

[0052] Working principle: when the clip body 11 is used to fix the drain pipe, the outer side of the drain pipe is brought into contact with the inner side of the top plate 34, and the clip body 11 is moved inward, the clip body 11 drives the top plate 34 to move inward, and the inward movement of the top plate 34 applies an inward thrust to the drain pipe, so that the inner side of the drain pipe contacts the inner wall of the tunnel. Since the force is mutual, the drain pipe applies an outward force to the top plate 34, and the outward movement of the top plate 34 drives the movable tube 33 to move outward, and the movable tube 33 drives the second telescopic spring 32 to be compressed. The second telescopic spring 32 generates an elastic force to push the top plate 34 outward, so that the top plate 34 always keeps in contact with the drain pipe, while the outer side of the drain pipe contacts the inner wall of the tunnel, and the second telescopic spring 32 can buffer the drain pipe through the top plate 34 to prevent the drain pipe from being damaged due to excessive pressure.
