Under the action of the inclined surface, the limiting seat 401c will move to the left, so that the limiting seat 401c is separated from the limiting groove 401d, and the limiting of the connecting rod 303c is released. The rod 303c can drive the cutting knife 303d or the grinding cylinder 303e to rotate with the rotating seat 203d. The first groove 402a is provided with two foreheads, and the two first grooves 402a are symmetrically arranged, and the first groove 402a located at the front is higher than the first groove 402a located at the rear side. The limiting seat 402c is slidably connected with the first groove 402a. The side wall of the limiting seat 402c and the inner wall of the extrusion groove 402e are both provided with inclined surfaces, so that when the connecting rod 303c located at the front moves backward or the connecting rod located at the rear side When the connecting rod 303c moves forward into the rotating seat 203d, the connecting rod 303c will squeeze the corresponding limiting seat 402c. At this time, the corresponding limiting seat 402c will slide into the first groove 402a under the action of the inclined surface. When the connecting rod 303c at the front or the connecting rod 303c at the rear is located in the middle of the rotating seat 203d, the limiting groove 402d is plugged and connected with the other corresponding limiting seat 402c to realize the restriction of the connecting rod 303c. The connecting groove 402f is connected with the two first A groove 402a is connected. When the limiting seat 402c at the front slides into the first groove 402a, it will squeeze the rotating seat 402g. The rotating seat 402g will deflect and squeeze the limiting seat 402c at the rear, thereby maintaining the stability of the position of the limiting seat 402c at the rear. When the limiting seat 402c at the rear side slides into the first groove 402a, the rotating seat 402g will be squeezed and deflected to squeeze the limiting seat 402c at the front, thereby maintaining the stability of the position of the limiting seat 402c at the front.

[0046] Furthermore, the fixing assembly 403 includes a sliding groove 403a arranged on the side wall of the limiting seat 402c, the inner wall of the sliding groove 403a is fixedly connected to the third spring 403b, the side wall of the third spring 403b is fixedly connected to the extrusion block 403c, the sliding groove 403a is slidably connected to the fixed block 403d, the inner wall of the limiting groove 402d is provided with a fixing groove 403e, the inner walls of the extrusion block 403c and the fixed block 403d are both rotatably connected to the rotating block 403f, and the corresponding two rotating blocks 403f are commonly fixedly connected with a connecting block 403g; wherein, the fixed block 403d is plug-connected to the fixed groove 403e.

[0047] Specifically, the sliding groove 403a is set in a T shape, two third springs 403b are provided, and the two third springs 403b are symmetrically arranged, the extrusion block 403c is slidably connected to the sliding groove 403a, two fixed blocks 403d are provided, and the two fixed blocks 403d are symmetrically arranged, and the two fixed blocks 403d are slidably connected to the sliding groove 403a, two rotating blocks 403f are provided on the inner side wall of the extrusion block 403c, and the two rotating blocks 403f are symmetrically arranged, and the fixed block 403d and the inner side wall of the fixed groove 403e are both provided with inclined surfaces.

[0048] When in use, in conjunction with Example 2, when the connecting seat 301c drives the connecting rod 303c to move forward or backward, the corresponding connecting rod 303c will be squeezed onto the corresponding fixing block 403d, and the fixing block 403d will slide into the sliding groove 403a under the action of the inclined surface, so that the fixing block 403d will be separated from the fixing groove 403e, and the squeezing block 403c will move toward the direction of the connecting rod 303c under the action of the rotating block 403f and the connecting block 403g, so as to release the limiting fixation of the connecting rod 303c. At the same time, the limiting seat 401c will gradually separate from the connecting groove 401e, and The first spring 401b and the third slide 401a move to the right under the action of the first spring 401b and the third slide 401a, so that the limiting groove 401d is inserted into the corresponding limiting groove 401d, so that the corresponding connecting rod 303c is fixed with the corresponding second slide 303b, and the connecting rod 303c is limited to prevent the connecting rod 303c from deflecting, which requires manual intervention to adjust the angle of the connecting rod 303c during the switching process so that it can be smoothly inserted into the rotating seat 203d. When the other connecting rod 303c gradually moves into the rotating seat 203d, the limiting seat 401c will gradually insert into the connecting groove 401e At this time, the limiting seat 401c will move to the left under the action of the inclined surface and the third slide groove 401a, so that the limiting seat 401c will be separated from the limiting groove 401d. At the same time, the extrusion groove 402e of the corresponding connecting rod 303c will squeeze the corresponding limiting seat 402c, and the limiting seat 402c will slide into the first groove 402a under the action of the inclined surface and the first groove 402a. The corresponding connecting rod 303c continues to move into the rotating seat 203d and gradually moves towards the other limiting seat 402c. When the corresponding limiting seat 402c is inserted into the corresponding limiting groove 402d When the extrusion block 403c is squeezed, it will slide into the sliding groove 403a, so that the corresponding two fixed blocks 403d are moved away from each other and inserted into the corresponding fixed groove 403e under the action of the rotating block 403f and the connecting block 403g, thereby realizing the limited fixation of the corresponding connecting rod 303c. At this time, start the motor, and the rotating seat 203d can drive the connecting rod 303c to rotate. When switching the cutting knife 303d or the grinding cylinder 303e, the limited fixation of the connecting rod 303c and the rotating seat 203d can be realized to ensure that the rotating seat 203d can smoothly drive the corresponding connecting rod 303c to rotate. In summary, in conjunction with Example 2, and through the cooperation of the limit component 401, the limiting component 402 and the fixing component 403, when switching the cutting knife 303d or the grinding cylinder 303e, the connecting rod 303c and the rotating seat 203d can be limited and fixed, thereby ensuring that the rotating seat 203d can smoothly drive the corresponding connecting rod 303c to rotate.
