[0037] A use method of a large PE pipe continuous cutting and stacking device, comprising the following steps:

[0038] Step A, adjustment: according to the required length of the product, adjust the length of the locking frame 5 from the cutting machine 2, when adjusting, first release the locking of the locking frame 5, move it according to the measurement until the proximity switch 6 on the surface reaches the predetermined length, and then lock it with the side surface of the guide rail 4 again;
