Specifically, the tool rest 5 comprises a head and a connecting rod part connected with the head, the head is abutted to the bottom surface of the cutter head 3, a sealing ring is assembled between the head and the cutter head, a ball bearing assembly 32 is arranged in the connecting rod part, and the connecting rod part penetrates through the assembling hole 30 and is assembled with a nut 6, so that the first crushing cutter 1, the second crushing cutter 2 and the cutter head 3 are assembled and fixed.

Referring to fig. 3 to 9, in one embodiment, the included angle between the first connecting arm 12 and the first substrate 10 is 120 ° < β < 180 °. Through with the blade of first crushing sword 1 upwards bends, can push down the surface of water when cooking machine work cutting surface of water, and thick liquid risees along cooking cup wall by a wide margin under the inertia effect when avoiding smashing to influence crushing efficiency. Preferably 155 < beta < 165 deg.

The outer end surface of the first connecting arm 12 is provided with a first cutting surface 120, and the outer end surface of the first bending part 13 is provided with a second cutting surface 130. The provision of the first and second cutting surfaces 120 and 130 increases the crushing area of the first crushing blade 1, thereby improving the crushing efficiency.

The included angle between the first bending part 13 and the first substrate 10 is 70 degrees < gamma < 110 degrees. By setting the bent angle of the first bent portion 13 upward, the cutting area of the first crushing blade 1 can be increased to crush food better. Preferably 85 DEG < gamma < 95 deg.

The second crushing blade 2 includes a second base 20, and a first blade 21 and a second blade 22 extending from the second base 20 and intersecting with each other. The first blade 21 includes a connection portion 210 bent downward from the second base 20 and an extension portion 211 horizontally extending from an end of the connection portion 210. The second blade 22 is a straight-edged knife. Through set up the connecting portion 210 of buckling and be in low-order extension portion 211 on the first blade 21 of the second crushing sword 2, the cooking machine during operation, the cutting and stirring function are smashed to the multilayer that the cooperation of second crushing sword 2 and first crushing sword 1 realized in the axial is favorable to promoting crushing efficiency. Indeed, in another embodiment, the second blade may be a separately provided blade. Which can be assembled between the first crushing cutter and the second crushing cutter and also can be positioned at the topmost layer or the bottommost layer of the crushing cutter component.

In one embodiment, the distance between the bottom surface of the extension part 211 and the bottom of the cutter head is 0 < h1 and is not less than 30 mm. The included angle between the connecting part 210 and the second base body 20 is more than 90 degrees and less than 150 degrees. The distance between the second crushing cutter and the cutter head 3 is reduced, so that the food materials can be prevented from being deposited at the bottom of the stirring cup, and the crushing effect can be better realized; the first blade 21 is provided with a bent connecting part 210 and a low-level extending part 211, and the functions of multi-layer crushing, cutting, stirring and the like in the axial direction are realized by matching with the second blade 22 and the first crushing cutter 1. In one embodiment of the application, 1.5mm < h1 ≦ 6mm is preferred; preferably 115 DEG < alpha < 125 deg.

The included angle between the connecting part 210 and the extension part 211 is more than 90 degrees and less than alpha₁< 150 deg.

The distance between the outermost end of the smashing knife along the circumferential direction and the inner wall of the cooking cup 7 is 0 < h4 < 20 mm. The crushing blade is the one having the smallest distance in the circumferential direction between the first crushing blade 1 and the second crushing blade 2 and the inner wall of the cooking cup 7. The smaller the distance between the blade of the crushing knife and the inner wall of the cooking cup 7 is, the larger the stirring range of the crushing knife can be, and the better the stirring effect is; but when smashing the sword and arranging the cup inside wall and too being close, smash the risk that the sword had the cutting cup lateral wall when high-speed rotation, only need in safety range can. Preferably 1mm < h4 < 8 mm.

Referring to fig. 8 and 9, in another embodiment, the center of the bottom of the cutter head axially protrudes upwards to form an accommodating portion 31 with an inner space, a bearing assembly 32 is integrally formed in the accommodating portion 31, an assembly hole 30 is formed in the top surface of the accommodating portion 31, and the first crushing cutter 1 and the second crushing cutter 2 are assembled and fixed with the cutter head 3 through a cutter shaft 4 passing through the assembly hole 30 and the bearing assembly. By providing the receptacle 31 at the bottom of the cutterhead and integrally forming the bearing assembly 32 with the receptacle 31, the assembly of the size reduction assembly 100 is made easier, thereby reducing costs.
