Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
With reference to Fig. 1-Fig. 4, the screw stem combined structure of a kind of extruder, including the first screw rod 1 and the second screw rod 2.
First screw rod 1 includes the first screw body 11 and the first rotating shaft 12, and the first screw body 11 surface is provided with the first screw thread
111, it is provided with the first internal spline 112 in the first screw body 11, the first rotating shaft 12 is provided with the first external splines 121, the first external splines
121 and first the size of internal spline 112 match, and the first internal spline 112 be provided with first in connect tooth 113, the first external splines
121 are provided with outside first and connect tooth 122, connect and connect the size of tooth 122 outside tooth 113 and first and match so that connect outside first in first
Connecting tooth 113 in tooth 122 and first to be installed by alignment, the first internal spline 112 and the first external splines 121 alignment are installed, and i.e. first
