Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to shown in Fig. 1-4, a kind of reciprocating screw for extruder, including mandrel 1 and bushing 2, be arranged on mandrel 1
There is a columned bushing 2, one end of mandrel 1 is provided with helical fastener 3, the top of mandrel 1 installation swivel head composition 4, and core
