By setting two sets of rubber blocks 16, the lateral limit of the first support block 3 and the rotating block 4 can be achieved to ensure the stability of the first support block 3 and the rotating block 4 on the outside of the flange 2.

[0024] Furthermore, refer to Figure 1 and Figure 4 It can be seen that the first support block 3 has symmetrically distributed sleeve rods 11 on its side, and each sleeve rod 11 has an insertion rod 12 inserted inside. The other end of the insertion rod 12 is connected to the second support block 13 through a bearing. During use, the lateral position of the second support block 13 can be adjusted by the cooperation of the sleeve rods 11 and the insertion rods 12. The second support block 13 can support the drain pipe 1 and effectively prevent the drain pipe 1 from deforming during use.

[0025] Furthermore, refer to Figure 4 It can be seen that the end of the insertion rod 12 away from the second support block 13 is connected to a slider 14. The sleeve rod 11 has a groove inside that matches the slider 14. When the worker pulls the second support block 13 laterally, the slider 14 connected to the side of the insertion rod 12 is able to slide along the inner wall of the groove under force, thereby realizing the lateral guidance operation of the second support block 13.

[0026] Furthermore, refer to Figure 2 and Figure 4It can be known that the side of the first supporting block 3 is symmetrically connected with a threaded column 15, and the inside of the sleeve rod 11 is provided with a threaded groove matched with the threaded column 15, and in use, through the cooperation of the threaded column 15 and the threaded groove, the staff can separate the sleeve rod 11 by rotating the sleeve rod 11, so that the land area of the device can be reduced during storage and transportation.
