It can be understood that the shape of the blade back 133 is set so that the blade 13 has a structure with a wide blade end and a narrow blade tip. At this time, it is ensured that the strength of the connection between the blade 13 and the base body 11 is greater than the load on the end of the blade 13 away from the base body 11, thereby The possibility of knife breakage can be reduced, which is beneficial to ensure that the crushing knife 10 has a certain service life. At the same time, the third segment body 139 is arranged at an inclination, so that the ingredients can flow along the third segment body 139 and quickly converge, so that the next blade 13 can cut it again.
