Embodiments of the present invention will be described below with reference to the drawings.

1 to 6, the cutter 6 pivotally supported by the container base 5 is rotated via the lower connector 3 and the upper connector 4 directly connected to the electric motor 2 built in the main body 1 to rotate the fruits and fruits in the container 7. Vegetables and liquid are cut, crushed and stirred. The boss 10 of the relay component 9 projects from the hole 8 on the inner bottom surface of the container base 5. The container 7 and the container base 5 are screw-fitted by a male screw 11 and a female screw 12 formed respectively. The relay component 9 is fixed to the container base boss 13 via a spring 14, a washer 15 and an interference component 16 by a screw 17 with a seat.
As a result, the relay component 9 is urged upward by the spring 14 and moves vertically by pressing the boss 10. The interference part 16 rotates and operates in the circumferential direction because the container base boss 13 passes through the two long holes 18 and the washer 15 and is screwed by the screw 17 with the seat. The protrusion 19 provided on the relay component 9 fits into a crank-shaped slit 20 provided on the interference component 16.

In a case where the container base 5 is to be mounted on the convex portion 21 formed on the main body 1 without fitting the container 7 to the container base 5, the convex portion 21 is equally divided into 12 on the back surface of the container base 5. The ribs 22 are fitted between the arranged ribs 22, but the interference parts 16
And cannot be mounted because it is obstructed by the projection 23 provided on the front panel. When the container 7 is fitted on the container base 5, the boss 10 is pushed by the container bottom surface 24, and the relay component 9 moves downward. The downward movement is caused by the protrusion 19 of the relay component 9.
And the slit 20 provided in the interference component 16 converts the interference component 16 into a rotational operation in the circumferential direction, and the projection 23
Rotates to a position where it does not interfere with the projection 21. As a result, the container base 5 can be mounted on the main body 1, the lower connector-3 and the upper connector-4 are connected, and the cutter 6 can be rotated by the power of the electric motor 2. Therefore, unless the container 7 is mounted on the container base 5 as described above, the container base 5 cannot be mounted on the main body 1 and the cutter 6 does not rotate while the cutter 6 is exposed to the outside. Accordingly, it is possible to prevent the user from touching the rotating cutter by mistake and injuring the cutter, thereby significantly improving safety.

When the container 7 mounted on the container base 5 is detached from the main body 1 and the container 7 is removed from the container base 5, the projection 23 rotates by the urging force of the spring 14, and returns to the position where it interferes with the projection 21 again.

The slit 20 of the interference component 16 has a strain
A connection part 25 is provided. Even if the projection 19 of the relay part 9 moves downward in the section of the straight part 25, the interference part 16 does not rotate or operate in the circumferential direction. Therefore, when the container base 5 is placed on the convex portion 21 on the main body 1 without mounting the container 7 on the container base 5 and the container base 5 is pressed from above and is forcibly mounted, the protrusion 23 of the interference component 16 becomes convex. Since the container base 5 does not rotate even if pressed by the part 21, the container base 5 does not fit to the main body 1. Therefore, safety can be further improved.

Further, three convex portions 21 on the main body 1 are provided at equal intervals of 120 ° and are divided into three. Correspondingly, the ribs 22 of the container base 5 and the projections 23 of the interference component 16 are set at 30 °.
Twelve pieces are provided at equal intervals in twelve parts. Therefore,
The user can place the container 7 with the container base 5 on the main body 1 in 12 patterns, and the position of the handle of the container 7,
The container 7 can be placed on the main body 1 from all directions without worrying about restrictions such as right-handed and left-handed. Therefore, the usability is improved and the merchantability can be improved.

Further, a straight portion 25 is provided in the slit 20 of the interference component 16, and two relay components 9 are provided.
Two corresponding slits 20 and two straight portions 25 are also provided. As a result, even if the boss 10 of the relay component 9 is to be pushed down by one finger, the projection 19 of the other relay component 9 is regulated by the straight portion 25, and the interference component 16 rotates and moves.
Do not work. Therefore, the projection 23 of the interference component 16 does not move from a position where it interferes with the fitting of the container base 5 and the projection 21. Therefore, the container base 5 cannot be placed on the main body.
As a result, it is possible to more reliably prevent the danger caused by the abnormal use of the user, and the safety can be further improved.
