DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 a concrete pipe inner wall pressing and smoothing device, which includes a base 1, a locking pin 2 is arranged on the base 1, a driving motor 3 is installed on the upper surface of the base 1, a rotating disk 4 is installed on the driving motor 3, and a plurality of plastering arms 5 are arranged on the rotating disk 4;

[0018] In this solution, there are specifically four plastering arms 5, and they are evenly distributed on the rotating disk 4. By driving the rotating disk 4 to rotate through the driving motor 3, the plastering arms 5 can be rotated;
