[0002] A tool used for well completion or cementing at the oil field. The perforating gun is a combination of equipment and its supporting parts used for perforating oil and gas wells. The most widely used is the energy-gathering perforating gun, which uses the energy-gathering phenomenon of explosion to generate an energy-gathering jet to perforate the formation. The model of the perforating gun is represented by its outer diameter. The selection of the perforating gun needs to match the production casing and wall thickness, otherwise gun jamming accidents are likely to occur.

[0003] However, during the use of the existing special alignment device for assembling the perforating gun, two parts need to be docked together when the perforating gun is assembled. At this time, the alignment device is needed for docking. Due to the poor flexibility of the alignment device, it is impossible to adjust multiple positions and directions according to the alignment requirements, resulting in the perforating gun being unable to be aligned during assembly, thereby affecting the assembly efficiency of the perforating gun. For this reason, we propose a special alignment device for assembling the perforating gun. Utility Model Content
