The rest of the technical scheme is completely the same as that of the embodiment 1.

During the specific use, revolving door 3 changes into closed state from the open state: when the revolving door 3 is in the open state, that is, the door opening 32 faces forward, the stopper 36 is attached to the rear side of the positioning plate 512 at this time, the positioning plate 512 stops the stopper 36 from continuing to rotate, and as long as manual operation is not performed, the revolving door 3 can be ensured to be still when in the open state, as shown in fig. 15; at the moment, the door body 31 is rotated anticlockwise, and when the stop block 36 on the door body 31 approaches the microswitch 2, the stop block 36 can push the action handle 21 of the microswitch 2 along with the rotation of the door body 31, so that the microswitch 2 is switched on; meanwhile, the steel ball 511 at the bottom of the upper tray body 5 is clamped into the steel ball clamping groove 401 at the top of the boss 33, and at the moment, the revolving door 3 is closed and is clamped and fixed, as shown in fig. 14; at the moment, the door opening 32 is just positioned at the rear side of the ice shaver, the rotating door 3 is in a closed state, namely the ice shaver is in a standby working state, and at the moment, the ice shaver can be started as long as the power switch 14 at the front side of the top cover 13 is pressed down as the microswitch 2 is connected with a power supply circuit of the ice shaver; therefore, the arrangement of the microswitch 2, the rotating door 3 and the stop block 36 can realize that the ice shaving machine can shave ice only when the rotating door 3 is closed, and the potential safety hazard caused when an operator opens and closes the door randomly when the machine works is avoided.

The revolving door 3 is turned from the closed state to the open state: when the revolving door 3 is in a closed state, that is, the door opening 32 is located at the rear side of the ice shaver, at this time, the steel ball 511 at the bottom of the upper tray body 5 is clamped in the steel ball clamping groove 401 at the top of the boss 33, so that the revolving door 3 can be kept still when in the closed state, as shown in fig. 14; at the moment, the door body 31 is rotated along the pointer, firstly, the steel ball 511 gets rid of the clamping action with the steel ball clamping groove 401, then, the door body is rotated, and along with the rotation of the door body 31, the stop block 36 releases the pushing action on the action handle 21 of the microswitch 2, so that the microswitch 2 is disconnected; with the continuous rotation of the door body 31, the stopper 36 is attached to the positioning plate 512, the positioning plate 512 stops the stopper 36 from continuously rotating, as shown in fig. 15, at this time, the door opening 32 just rotates right ahead, the ice claw disc 9 can be touched, the rotating door 3 is in an open state, the ice shaver is in a non-working state, at this time, the power supply circuit of the ice shaver cannot be switched on due to the disconnection of the microswitch 2, even if the power switch 14 is pressed, the power supply of the ice shaver is not switched on at this time, therefore, when the door body 31 is not closed, the ice shaver does not work, and the safety of ice shaving is ensured.

In the state of fig. 15, the ice cubes are placed under the ice claw disk 9, and then the door body 31 is rotated counterclockwise to reach the state of fig. 14; at this time, the power switch 14 is pressed to supply power to the ice shaving machine, so that the motor of the motor driving assembly 13 is started to realize the downward rotation of the screw rod 8 and the ice claw disc 9, and the ice cubes arranged on the ice shaving disc 7 and under the ice claw disc 9 rotate along with the rotation, so that the ice cubes are cut by the blade fixed on the ice shaving disc 7, and the ice shaving is realized.

Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the present invention, and those skilled in the art should understand that, based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without inventive labor are still within the scope of the present invention.
