In this embodiment, in order to facilitate maintenance of the rotary cutter set, the rotary cutter set is limited to be detachably fixed on the cutter set rotating shaft 41; specifically, the knife group rotating shaft 41 is provided with a screw part and a plurality of first limiting surfaces 410, the first blade 42 is provided with a first limiting hole 420 which is sleeved on the knife group rotating shaft 41, and the second blade 43 is provided with a second limiting hole 430 which is sleeved on the knife group rotating shaft 41; the first limiting surface 410, the first limiting hole 420 and the second limiting hole 430 are clamped and configured, so that the first blade 42 and the second blade 43 can rotate together with the tool set rotating shaft 41;

further, a rotating shaft flange (not shown) capable of supporting the first blade 42 and the second blade 43 from the bottom is disposed on the cutter group rotating shaft 41, and a nut 45 is connected to the screw portion; the nut 45 can press the first blade 42 and the second blade 43 from the top to fix them in the axial direction of the blade group rotating shaft 41.

As an embodiment of the present application, the tool holder 40 is fixed in the through hole by the fastener 5; specifically, the tool post 40 is provided with a clamping and pressing surface 400 which can be clamped and pressed on the upper part of the through hole, and a bearing block 402 which can pass through the through hole, and the buckle 5 is arranged on the lower part of the through hole and can pull the bearing block 402, so that the tool post 40 and the pot base 21 are fixed.

In order to facilitate the removal of the knife assembly 4 and in consideration of the installation space of the knife assembly 4 and the holder 5, it is preferable that an annular projection 211 is provided in the pot base 21, and the chucking pressure surface 400 is chucked and pressed on the top of the annular projection 211.

Referring to fig. 16 and 17, the number of the bearing blocks 402 is plural, and they are uniformly provided on the side of the tool holder 40 in the circumferential direction; further, the buckle 5 comprises a ring body 50, the inner diameter of the ring body 50 is not smaller than the size of the through hole, and the inner side of the ring body 50 is provided with clamping blocks 55 corresponding to the number and the positions of the bearing blocks 402; gaps (not shown) into which the receiving blocks 402 can be fitted are provided between the plurality of latch blocks 55.

Referring to fig. 13, the pressure block 402 has a pull-press top surface 4021 and an embedded bottom surface 4022, and the latch 55 has a guide surface 552 capable of being pressed against the pull-press top surface 4021, and a positioning surface 551; the guide surface 552 is smoothly abutted with the locating surface 551, and the guide surface 552 is used for guiding the tension and compression top surface 4021 to the locating surface 551.

Further, the end of the locating surface 551 remote from the guide surface 552 is provided with a locating block 54, indicating that the catch 5 has secured the knife assembly 4 in place when the bearing block 402 contacts the locating block 54.

In the present application, an inclination angle c is configured between the guiding surface 552 and the horizontal plane, and the inclination angle c is limited to 18-30 ° in order to enable the buckle 5 and the tool holder 40 to be fast clamped without jamming; preferably, the guide surface 552 is slightly curved (concave or convex) so that the seating surface 551 is substantially parallel to the horizontal.

In order to facilitate the rotation of the buckle 5, pressing plates 52 with arc-shaped longitudinal sections are symmetrically arranged on two sides of the bottom of the ring body 50, and a thumb pressing plate 53 is arranged on one of the pressing plates 52; wherein, both sides of the pressing plate 52 are symmetrically in an asymptote or arc shape, and the root size of the connection between the pressing plate 52 and the ring body 50 is larger than the tip size of the pressing plate 52. Based on this ergonomic design, the user conveniently applies force to the buckle 5 through the index finger and thumb, and user operation experience is improved.

In order to prevent the knife holder 40 from rotating in the process of clamping the buckle 5 with the knife holder 40 and also prevent the knife holder 40 from rotating when the knife group rotating shaft 41 rotates, referring to fig. 8, a plurality of caulking grooves 2100 corresponding to the pressure-bearing blocks 402 are uniformly arranged in the through hole, and a plurality of positioning blocks 401 capable of being correspondingly inserted and embedded in the caulking grooves 2100 are arranged on the knife holder 40, so that the knife holder 40 can be fixed on the pot base 21 along the circumferential direction; it is apparent that a plurality of the positioning blocks 401 are disposed at an upper layer of the pressure block 402, which does not need to pass through the through-holes.

In this embodiment, the circumference formed by the outer side surfaces of the positioning blocks 401 substantially coincides with the circumference formed by the outer side surfaces of the bearing blocks 402, that is, the bearing blocks 402 need to pass through the caulking grooves 2100 to be matched with the buckles 5; to facilitate penetration of the bearing block 402, the width h1 defining the locating block is greater than the width h2 of the bearing block; meanwhile, it may be defined that the size of the embedding bottom surface 4022 is smaller than that of the tension and compression top surface 4021, that is, the section of the forward bearing block 402 is substantially in the shape of an isosceles trapezoid.

In a specific application scenario, in a top view, in order to conveniently insert the tool apron 40, the pressure-bearing block 402 may be configured in the projection of the positioning block 401; however, after the buckle 5 is removed or accidentally dropped, the knife assembly 4 can smoothly fall out of the through hole, which not only damages the knife assembly 4, but also may cause a risk to a user, which is difficult to predict; thus, in a plan view, the pressure receiving block 402 and the positioning block 401 are uniformly spaced from each other, and with this configuration, even if the holder 40 is not restricted by the hook 5, the holder 40 can be removed from the through hole after a certain rotation, thereby solving the above-described problem.

Specifically, the number of the pressure-bearing blocks 402, the positioning blocks 401 and the caulking grooves 2100 can be 2-10, and the number of the pressure-bearing blocks, the positioning blocks 401 and the caulking grooves 2100 is preferably 3 in consideration of production cost and use stability; in the process of mounting the knife assembly 4, after the bearing block 402 correspondingly passes through the insertion groove 2100, the knife holder 40 is rotated by 60 degrees, so that the positioning block 401 is correspondingly inserted and embedded in the insertion groove 2100, and finally the bearing block 402 is pulled by the buckle 5, thereby completing the fixation of the knife assembly 4.

Referring to fig. 6 and 7, in order to accommodate part of the knife assembly 4 and part of the catch 5, a first recess 2101 is formed at the bottom of the pan base 21; in order to facilitate the user to rotate the pressing plate 52 and the thumb press plate 53, and to hide the clasp 5, the bottom of the first recess 2101 is also formed with a second recess 2102; wherein the cross-sectional dimension of second recess 2102 is greater than the cross-sectional dimension of first recess 2101, second recess 2102 is substantially I-shaped.
