[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-3 A perforated pipe for easy docking shown in the figure includes a first connecting pipe 1 and a second connecting pipe 2. A sleeve 8 is fixedly provided at the end of the first connecting pipe 1, and an annular groove 10 is provided at the end of the second connecting pipe 2. The sleeve 8 is nested and connected with the annular groove 10. A plurality of aligned positioning blocks 4 are equidistantly fixed on the outer walls of the first connecting pipe 1 and the second connecting pipe 2. A through hole 6 is provided in the middle of the plurality of positioning blocks 4. A screw 12 is inserted and connected between the two aligned through holes 6, and hexagonal nuts 11 are threadedly connected at both ends of the screw 12.
