[0029] When the food processor 100 starts to work, the motor starts, the output shaft of the motor starts to rotate, and the butt joint clutch and the clutch 423 will collide. Since the skeleton cladding layer 21 is cladded on the hard skeleton 10, the skeleton cladding layer 21 can play a role in shock absorption and noise reduction. In addition, since the hard skeleton 10 comprises the through hole 111, and the skeleton cladding layer 21 comprises the third part 213 penetrating the through hole 111, and the third part 213 is connected with the first part 211 and the second part 212, the skeleton cladding layer 21 and the hard skeleton 10 are more closely combined together. In this way, the overall structure of the clutch 423 is more stable and reliable.

[0030] The transmission tooth 22 comprises an abutting surface 225, which is provided with a plurality of support ribs 226. Since the support ribs 226 have elasticity and can be deformed under stress, the abutting surface 225 is prevented from being torn in operation, and the structure is more stable and reliable.
