FIG. 9 is a perspective view showing an operating state of a pin, a fixing plate, and a release button when the blender is located at the operating position according to an embodiment of the present invention, and the two-dot chain line is an enlarged view when viewed from the side. Hereinafter, the process of fixing the head moved from the release position to the operation position to the operation position will be described with reference to the above-described configurations and FIGS. 5 to 10. FIG.

When the head 300 is in the unlocked position, the constructions of the fixed unit 400 are positioned as shown in Fig. 5, the pin 440 is hooked on the pin hole and exposed to the outside of the head 300, and the lever 430 is supported on the pin 440. At this time, a pressing member 430a is provided between the lever 430 and the inner upper surface of the head 300 (the inner surface of the head upper case 340) to elastically press the lever 430 downward.

When the head 300 is lowered for the operation of the mixer, the pin 440 is supported on the upper surface of the container lid 250 as shown in FIG. 2 and the lower surface of the head body portions 310, 340, The case 310). That is, when the head 300 moves downward, the pin 440 can move upward, which is a direction opposite to the head 300.

When the pin 440 moves upward, the lever 430 supported by the pin 440 moves in a direction to press the protrusion 425 (upward in FIG. 5). When the protrusion 425 is pressed, 420 can be resiliently displaced such that the fixing projections 427 are inserted into the engaging jaws 127 (see FIG. 10). Therefore, the rise of the head 300 can be prevented by engaging the fixing protrusion 427 with the engaging jaw 127, so that the head 300 can be fixed to the operating position.

The fixing plate 450 is pressed in the direction opposite to the supporting direction by the upward movement of the pin 440. When the pin 440 is sufficiently lifted, the fixing plate 450 is restored to the supporting direction and inserted into the lower side of the supporting projection 445 (See FIG. 9).

More specifically, the fastening plate 450 includes a first support surface 456 that is supported by a side 446 facing the fastening plate 450 of the support protrusion 445 when the head 300 is in the unlocked position (See FIG. 9), and the side 446 of the first support surface 456 and the support protrusion 445 is formed to be inclined downward along the direction from the pin 440 toward the fixing plate 450 When the pin 440 moves upward with respect to the fixing plate 450, the fixing plate 450 is pressed in the direction opposite to the supporting direction and can be restored to the lower side of the supporting protrusion 445.

When the fixing plate 450 moves to the lower side of the support protrusion 445, the lowering of the lever 430 and the pin 440 can be prevented. When the downward movement of the lever 430 is blocked, The lever 430 can continue to press the projection 425 of the fixed panel 420 to keep the head 300 inserted in the operating position 127 so that the head 300 can be fixed in the operating position.

In other words, when the head 300 descends and the pin 440 is supported by the head cover 250 and moves upward, the lever 430 supported by the pin 440 moves in the direction in which the protrusion 425 is pressed So that the fixing projections 427 are moved toward the engaging jaws 127 side. The head 300 continues to descend until the fixing plate 450 is restored to the lower side of the supporting protrusion 445. At this time, the fixing protrusion 427 can move downward on the inclined surface formed on the engaging step 127 . When the force for pressing the head 300 to the operating position disappears after the fixing plate 450 is restored to the lower side of the support protrusion 445 and the force for pressing the lever 430 downward is applied to the pressing member 430a The lever 430 moves downward and the head 300 rises a little so that the pin 440 supported by the fixing plate 450 also moves up with the head 300 to be slightly spaced from the head cap 250 The lever 430 is not displaced enough to disengage the locking protrusion 427 from the locking protrusion 127 so that the locking protrusion 427 is still caught by the locking protrusion 127, .

The process of moving the head to the release position by releasing the fixation at the operation position

Hereinafter, with reference to FIGS. 5 to 10, a process of releasing the position fixation of the head fixed to the operation position and moving it to the release position will be described.

When the release button 460 is pressed in the direction toward the lever 430, the fixing plate 450 inserted into the lower side of the support protrusion 445 can be pressed in the direction opposite to the supporting direction. To this end, the release button 460 includes an inclined surface 462 that is inclined toward the side away from the head fixing portion 360 along the horizontal direction from the lever 430 to the release button 460 and facing the fixed plate 450 And the fixing plate 450 may further include a pair of second supporting surfaces 452 inclined corresponding to the inclined surfaces 462 (see FIG. 6). When the release button 460 is pressed in the direction toward the lever 430, the fixing plate 450 can be moved in the direction opposite to the supporting direction by the action of the second supporting surface 452 and the inclined surface 462.

The lever 430 and the pin 440 can be pressed downward by the pressing member 430a pressing the lever 430 when the fixing plate 450 is completely disengaged from the lower side of the support protrusion 445. [ When the lever 430 moves downward, the pressing force of the protrusion 425 of the fixing panel 420 disappears, and the fixing panel 420 can be displaced to the original position so that the fixing protrusion is separated from the locking protrusion 127 .

That is, if the fixing plate 450 is disengaged from the lower side of the supporting protrusion 445 and does not support the supporting protrusion 445, the force of the pressing member 430a causes the pin 500, which is slightly spaced from the head cap 250, The fixing plate 420 is displaced so that the fixing protrusion 427 is disengaged from the engaging protrusion 427 by the lowering of the lever 430 and the lower lever 440 descends to the head lid 250 side, The fixing of the head 300 can be released.

At this time, the head 300 may have a restoring force to move upward. The user can move the head 300 from the operating position to the release position by pressing the release button 460 only when the head 300 has restoring force to move upward.

The stand 120 may further include an elastic member 124a provided on the outer circumferential surface of the pillar member 124 so that the elastic member 124a is pressed while the head 300 moves to the operating position, The head 300 can have a restoring force to move upward.
