[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] like Figure 1 , Figure 3 As shown, this utility model discloses an ice grinding disc, including a working tray 1. The bottom surface of the working tray 1 has five rows of connecting holes. The five rows of connecting holes are arranged along the same side of the five corners of a regular pentagon. Each of the five rows of connecting holes is connected to a knife 2 through a locking assembly. The center of the working tray 1 is provided with a conical and upwardly protruding connecting part 11. The center of the connecting part 11 is provided with a connecting hole 111.

[0024] Among them, such as Figure 1 As shown, if the blades 2 on the bottom of the work tray 1 are rotating clockwise to grind ice, then each blade 2 is installed on the right corner of the five points of a regular pentagon; as shown... Figure 3 As shown, if the blades 2 on the bottom of the work tray 1 are rotating counterclockwise to grind ice, then each blade 2 is installed on the left side of the five corners of the regular pentagram; the included angle between two adjacent blades 2 is 108° or 72°.

[0025] like Figure 4-5 As shown, this utility model discloses an ice grinding disc, including a working tray 1. The bottom surface of the working tray 1 has eight rows of connecting holes. The eight rows of connecting holes are arranged along the same side of the eight corners of a regular octagon. Each of the eight rows of connecting holes is connected to a knife 2 through a locking assembly. The center of the working tray 1 is provided with a conical and upwardly protruding connecting part 11. The center of the connecting part 11 is provided with a connecting hole 111.

[0026] Among them, such as Figure 4 As shown, if the blades 2 on the bottom of the work tray 1 are rotating clockwise to grind ice, then each blade 2 is installed on the right corner of the eight points of the regular octagon; as Figure 5 As shown, if the blades 2 on the bottom of the work tray 1 are rotating counterclockwise to grind ice, then each blade 2 is installed on the left side of the eight corners of the regular octagon; the included angle between two adjacent blades 2 is 112.5° or 67.5°.

[0027] Example 1:
