The other side of the spring baffle 23 is connected to the telescopic wheel 21 through the telescopic wheel retainer 22. When the telescopic wheel 21 is compressed, the force is transmitted to the spring baffle 23 through the telescopic wheel retainer 22, at which time the spring 24 is compressed, and the length of the spring 24 is shortened. When the compression of the telescopic wheel 21 disappears, the pressure on the spring 24 disappears, and the spring 24 returns to its original length. The spring retainer 25 is fixedly connected to the fixed frame 1.

[0026] The spring fixer 25 is square, and the four sides of the spring fixer 25 are fixedly connected with the springs 24, all the springs 24 are in the same horizontal plane, the stability of the telescopic member 2 is ensured, and stable support for the prefabricated cement concrete pipe is facilitated.
