[0029] When using the device, the pump body 101 needs to be placed in a suitable position, and then the motor 102 is placed above the motor 102, and the disassembly unit 200 structure is placed between the pump body 101 and the motor 102, and between the upper and lower connecting frames 103, and then the motor 102 is pressed downward, and the upper and lower connecting frames 103 drive the ball screw 208 to rotate through the connecting assembly 202, and the multiple ball screws 208 drive the gear 204 to rotate, and the gear 204 drives the gear ring 2010 to rotate by meshing with the gears between the gears 2010, and the gear ring 2010 drives the clamping assembly 205 structure to rotate during the rotation process, and the clamping assembly 205 structure fixes the upper and lower staggered plug plates 206;

When the disassembly unit 200 structure needs to be disassembled, the auxiliary unit 203 structure needs to be disassembled first, and then the disassembly between the two connecting frames 103 can be completed. The assembly of the pipeline pump structure can be effectively completed through the mutual cooperation between the structures. The connection structure is simple, thereby improving the disassembly efficiency of the pipeline pump by the staff, facilitating the staff to repair the pipeline pump, and at the same time improving the sealing effect of the pipeline pump, so that the structure can be used in combination.
