The second base 312 includes the driving position where a predetermined tension is generated in the driving force transmitting member 360 so as to transmit the driving force of the screw driving source 350 to the conveying screw 340 and the conveying screw ( It moves in the second direction with respect to the first base 311 between 340 and the removal position where the tension of the driving force transmission member 360 is removed so that it can be removed from the screw driving source 350,
The drive mechanism 380,
A driving bracket 381 fixed to the first base 311;
A driving bar 383 that penetrates the driving bracket 381 and is installed to be movable in the second direction, and one end thereof is fixed to the second base 312;
A handle bar 385 pin-connected to the driving bracket 381; And
A connecting piece 387 having both ends pin-connected to the other end of the driving bar 383 and one side of the handle bar 385, respectively; Including,
When the handle bar 385 is rotated, the drive bar 383 connected to the handle bar 385 is moved by the connecting piece 387, and the second base at which one end of the drive bar 383 is fixed. The stirrer 312 is moved so that the second base 312 is located in either a driving position or a removal position with respect to the first base 311.
The method of claim 1,
A stirrer further comprising a guide member (370) for guiding the movement of the second base (312) in the second direction with respect to the first base (311).
The method of claim 2,
The guide member 370,
A guide slot 371 extending in the second direction in the second base 312; And
A guide protrusion 372 that is partially positioned on the guide slot 371 while being fixed to the first base 311; Agitator comprising a.
delete delete The method of claim 1,
The stirrer further comprises a cover part 391 installed to be rotatable with respect to the first and second bases 311 and 312 to selectively shield at least the screw driving source 350 and the driving force transmission member 360.
The method of claim 6,
With the cover part 391 shielding the screw driving source 350 and the driving force transmission member 360, rotation of the cover part 391 with respect to the first and second bases 311 and 312 is prevented. The stirrer further comprising a restricting locking member 392.
