(Function) The assembly procedure of the present invention is as shown in FIG.
After placing the ice-shaving case on the frame with the right side edge along the inclined surface 15 of the ruler plate 14, rotate the ice-shavings case counterclockwise while lightly pressing the ice-shaving case (FIG. 5). Then, the engaging pieces 32 on the inner circumference of the skirt portion 30 engage with the lower surfaces of the locking pieces 31 of the mounting seat 11, and the lower left end of the side wall 21 is connected to the ruler plate 1.
Both are fixed by coming into contact with the non-inclined surface on the left side of 4. To incorporate the rotor into the ice-shaving case, use the screw hole 1 at the upper end of the drive shaft 9 that protrudes into the case.
A screw 43 embedded in the boss 41 of the wing is screwed into the blade.

To remove the rotor, move the ice-shaving case clockwise onto the inclined surface 15 of the ruler plate 14. When the cam 33 rotates a little until it touches the side wall 21, the abutting piece 17
Since the intermediate gear 8a cannot be rotated by pressing down, rotate the rotor to the left to unscrew it and remove it. In this state, the locking piece 31 and the engaging piece 32 have already been disengaged, so the ice-shaving case can be removed from the frame and washed separately.

(Effects) As described above, the present invention includes a frame having a circular mounting seat surrounding the drive shaft protrusion on its upper surface, and an ice shaving case having a skirt portion that fits around the mounting seat on its lower surface. Fit the skirt part into the mounting seat and rotate the ice cutting case slightly to removably connect it to the frame.Inside the case, screw the screw embedded in the boss into the screw hole at the upper end of the drive shaft to attach the shaft. It is equipped with a rotary blade fixed to the ice cutting case, and a ruler plate is provided on the upper surface of the frame to restrict the rotation of the ice cutting case, and a cam is formed on the lower surface of the skirt with a spring interposed in the frame outside the mounting seat. According to the invention, an abutment piece that slides up and down is provided, and the lower end of the abutment piece is engaged with a stopper formed on a transmission gear inside the frame to stop the rotation of the gear and the drive shaft. The rotor blade can be easily removed from the drive shaft by turning it by hand in the opposite direction to the rotation direction.
