[0031] The working principle of the present application is as follows:

[0032] Referring to Figure 1 Figure 6 When the user needs to quickly disassemble the pipeline 12, at this time the user can rotate the rotating wheel 20 to drive the third ball screw 19 to rotate, thereby making the third ball screw 19 drive the screw nut sleeve 21, the mounting rod 14 and the roller 15 to move upwards, so that the whole pipeline 12 can slowly move upwards by a certain distance, then the user can pull one end of the pipeline 12, thereby making the bottom of the pipeline 12 smoothly taken out along the roller 15, thereby reducing the friction between the bottom of the pipeline 12 and the mounting plate 9, thereby prolonging the service life of the pipeline 12, and the sliding of the roller 15 and the bottom of the pipeline 12 can reduce the strength required by the user to pull the pipeline 12, thereby facilitating the user to disassemble and assemble the pipeline 12 to a certain extent.

[0033] ​When the user needs to disassemble the connecting device of the pipeline 12, the user only needs to insert one end of the positioning block 28 into the second through slot 27, then push the mounting plate 9 to drive the clamping block 25 to move to the left side, so that the clamping block 25 can be connected with the clamping groove 24, then the user can pull the pull block 37, at this time the bottom of the pull block 37 is no longer blocked by the limiting block 38 in the process of rebounding, so that the bottom of the positioning rod 33 can be connected with the positioning groove 34, thereby quickly fixing the positioning block 28, thereby facilitating the user to quickly disassemble the connecting device of the mounting pipeline 12, facilitating the subsequent movement of the product, and simultaneously facilitating the transportation of the product by disassembling the product into multiple sections.
