The invention relates to an extrusion device comprising at least one first head, a processing section and a first locker. The first head is adapted to connect with a first extruder, and the processing section is provided with a forming nozzle. The first locker applies clamping force to press the first head against the processing section along the first connecting direction (X). The locker includes a first clamping part and a locking motor. The clamping part moves along the second locking direction (Y) perpendicular to the connecting direction. The locking motor drives a pull rod to generate tension toward the anchoring point on the first head, so as to realize stable clamping and sealing connection.
