By setting the gear A5 and the gear B6, the torque of the long rod 7 can be increased and the speed can be reduced during the operation of the motor 4, so as to ensure that there is enough force to drive the cover plate 3 to open, start the motor 4 and drive the gear A5 to rotate, so that the gear B6 can be driven to rotate under the meshing action, so that the long rod 7 can be driven to rotate, and under the joint action of the reciprocating thread 8 and the inner thread of the moving platform 9, the moving platform 9 can be driven to move up and down, the top of the shell 1 is rotatably connected with the gear B6, and the inner side of the gear B6 is fixedly installed with a long rod 7. A reciprocating thread 8 is provided on the surface of the long rod 7, and a movable platform 9 is threadedly connected to the surface of the long rod 7. A thread is provided on the inner side of the movable platform 9, and the thread provided on the inner side of the movable platform 9 meshes with the reciprocating thread 8. The movable platform 9 is rotatably connected to the connecting plate 11. A protrusion 10 is fixedly installed on the inner side of the cover plate 3, and the surface of the protrusion 10 is rotatably connected to the connecting plate 11. A hook plate 12 is fixedly installed on the surface of the long rod 7. The number of the hook plates 12 is three groups and they are distributed in a circular shape on the surface of the long rod 7. A frame plate 13 is fixedly installed on the inner side of the shell 1, and a sliding rod 14 is inserted into the inner side of the frame plate 13. A limiting ball 15 is fixedly installed on one end of the sliding rod 14, and a striking head 16 is fixedly installed on the other end of the sliding rod 14. A spring 17 is sleeved on the surface of the sliding rod 14, and one end of the spring 17 is fixedly installed on the inner side of the frame plate 13, and the other end of the spring 17 is fixedly installed on the surface of the striking head 16.

[0027] Embodiment 2

[0028] See also Figures 6-7 A mounting plate 18 is fixedly installed on the top of the shell 1, and a placement plate 19 is fixedly installed on the top of the mounting plate 18. The top of the mounting plate 18 is rotatably connected to a limiting plate 20. A buffer pad 21 is arranged on the inner side of the placement plate 19. The buffer pad 21 is made of natural rubber. The buffer pad 21 made of natural rubber can effectively buffer the impact force caused by hammering to avoid damage to the shell 1 due to excessive impact force. A card slot 22 is opened on the inner side of the buffer pad 21. The limiting plate 20 is rotated so that it no longer rests on the inner side of the card slot 22, and then the buffer pad 21 can be pulled out from the inner side of the placement plate 19, and then the buffer pad 21 can be maintained and replaced.

[0029] Working principle: During operation, first align the housing 1 with the food to be sampled, then press downwards or drive the housing 1 to insert into the inside of the food by hammering the buffer pad 21. Then start the motor 4 and drive the gear A5 to rotate. Thus, under the meshing action, the gear B6 will be driven to rotate, which can drive the long rod 7 to rotate. Under the combined action of the reciprocating thread 8 and the thread inside the moving table 9, the moving table 9 will be driven to move up and down. During the movement, under the combined action with the connecting plate 11, the cover plate 3 will be driven to rotate along the rotating rod 2, so that the cover plate 3 can be opened. While the long rod 7 is rotating, the hook plate 12 will be driven to rotate. During the contact between the hook plate 12 and the limiting ball 15, the limiting ball 15 will be hooked under the action of force, and as the hook plate 12 rotates, the sliding rod 14 will be driven to slide outwards. During this process, the spring 17 will be compressed. As the hook plate 12 rotates, the limiting ball 15 will slide out at the end of the hook plate 12 and drive the striking head 16 to strike the inside of the housing 1 under the action of the spring 17, so that the housing 1 can be vibrated and the food around the cover plate 3 can be vibrated, thus avoiding blockage, and then the food sampling work at different levels can be completed. When the buffer pad 21 needs to be replaced, first rotate the limiting piece 20 so that it no longer abuts against the inside of the card slot 22, then the buffer pad 21 can be pulled out from the inside of the placement plate 19, and then the buffer pad 21 can be maintained and replaced. During installation, first place the buffer pad 21 inside the placement plate 19, then rotate the limiting piece 20 so that it abuts against the inside of the card slot 22 again, and at this time the placement and installation of the buffer pad 21 are completed.
