[0005] Preferably, an anti-slip pad is fixedly provided at the bottom end of the base, and the base is a truncated cone structure.

[0006] Preferably, a gravity block is provided in the installation groove, and the gravity block is detachably installed.

[0007] Preferably, a plurality of adjustment grooves are provided on the groove wall of the first through groove, and the adjustment grooves are distributed at equal intervals.

[0008] Preferably, a clamping block is welded on one end of the connecting rod, and the clamping block is clamped in the clamping block groove.

[0009] Preferably, an adjusting rod is welded on the rotating drum, and the adjusting rod passes through the first through slot.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the inner mold tube of the present invention is clamped in the block groove through the block on the connecting rod, and the inner mold tubes of different sizes can be replaced according to actual needs to manufacture prefabricated columns of different sizes, which is more flexible; by providing a number of equally spaced adjustment grooves, the length of the prefabricated column can be adjusted, which is more applicable; by providing a base with a truncated cone structure, the support stability is stronger; a gravity block is installed in the installation groove, which lowers the overall center of gravity and further improves the stability of the support; the gravity block is detachable and can be replaced with gravity blocks of different densities when necessary, which is more practical.
