[0014] The cam is an assembly made of a plurality of movable plates, each of which has a first end connected to a second end of the movable plate and a second end connected to the movable plate.

[0015] The usage and beneficial effects of the double-helix chip conveyor are as follows: when in use, the chips are discharged into the chip groove near one end of the first movable plate, and then the chips are driven toward the chip outlet through the different direction rotation of the positive spiral blade and the reverse spiral blade, until they move to the chip outlet and fall to the designated workstation.
