The bottom bracket 40 is arranged at the bottom of the cylinder body 10. A bottom bracket locking device 30 is arranged in the circumferential direction of the bottom bracket 40. The bottom bracket locking device 30 is used to connect the bottom tray. The hanging bracket 20 is fixed outside the cylinder body 10 and is arranged coaxially with the cylinder body 10. One side of the cylinder body 10 has an opening. The two ends of the opening extend in a direction away from the axis of the cylinder body 10 to form a convex part 11. A lock-opening device 60 is arranged on the cylinder body 10. The lock-opening device 60 is used to make the convex part 11 in a locked or loosened state.

[0030] By making the existing cylinder body 10 have an opening and a convex part 11, and controlling the states of the convex part 11 and the opening through the lock-opening device 60, when it is necessary to demold the concrete pipe, the convex part 11 and the cylinder body 10 are opened through the lock-opening device 60, so that the concrete pipe is separated from the inner wall of the cylinder body 10, thus facilitating the demolding of the concrete pipe.
