The inner side wall of the control rod 5 is rotatably connected to a rotating rod 17. The other end of the rotating rod 17 is rotatably connected to a connecting rod 8. By pressing the control rod 5, the rotating rod 17 can be rotated, and the rotation of the rotating rod 17 will rotate the connecting rod 8. The end of the connecting rod 8 away from the rotating rod 17 is rotatably connected to a rotating rod 29. The rotation of the connecting rod 8 causes the rotating rod 29 to rotate. The end of the rotating rod 29 away from the connecting rod 8 is rotatably connected to a card block 10. The left end of the card block 10 is fixedly connected to a limiting plate 11. The card block 10 is limited by the limiting plate 11. 0, the inner walls of the front and rear ends of the shell 4 are provided with a card slot 12, the outer part of the card block 10 is engaged with the inner wall of the card slot 12, so that the shell 4 can be fixed, and the inner parts of the front and rear ends of the sampler body 1 are provided with a storage slot 13, the outer part of the connecting rod 8 is rotatably connected to the inner wall of the storage slot 13, and the outer part of the limit plate 11 is slidably connected to the inner wall of the storage slot 13, so that the limit plate 11 can be more stable when sliding, and a spring 14 is provided inside the storage slot 13, one end of the spring 14 is fixedly connected to one side of the limit plate 11, and the other end of the spring 14 is fixed It is connected to the inner wall of one side of the storage groove 13, so that the spring 14 can be squeezed and the nut 6 can be unscrewed. At this time, by pressing the control rod 5, the rotating rod 1 7 will be rotated under the pressing of the control rod 5, and the rotating rod 1 7 will rotate with the connecting rod 8 when rotating, and the connecting rod 8 will rotate with the rotating rod 2 9 when rotating. The rotation of the rotating rod 2 9 pulls the card block 10 to move, so that the card block 10 exits the inner wall of the card slot 12 to complete the separation between the sampler body 1 and the shell 4, so that the sampler body 1 can be inspected and repaired.

[0024] refer to Figure 1 and Figure 3The four bottom corners of the sampler body 1 are fixedly connected with buffer components. Each buffer component includes a sliding column 15. The four sliding columns 15 are respectively fixedly connected to the four bottom corners of the sampler body 1. The bottom of the sliding column 15 is fixedly connected to a limiting column 16. The sliding column 15 is limited by the limiting column 16. The outer part of the sliding column 15 is slidably connected with a shell 17. The inner part of the shell 17 is provided with a slide groove 18. The outer part of the limiting column 16 is slidably connected to the inner wall of the slide groove 18.

[0025] Working principle: detection is performed by suction through the suction head 3, and when the sampler body 1 needs to be repaired, the nut 6 is unscrewed, and the control rod 5 is pressed, and the rotating rod 1 7 is rotated when the control rod 5 is pressed, and the rotating rod 1 7 is rotated when it is rotated, and the connecting rod 8 is rotated when it is rotated, and the rotating rod 2 9 is rotated, and the card block 10 is pulled to move by the rotation of the rotating rod 2 9, so that the card block 10 is withdrawn from the inner wall of the card slot 12 to complete the separation between the sampler body 1 and the shell 4, so that the sampler body 1 can be repaired, and the control rod 5 is pressed again when it needs to be installed, and the shell 4 is inserted into At the left end of the sampler body 1, the control rod 5 is released. When the control rod 5 is released, the spring 14 will push the limit plate 11, so that the limit plate 11 will be reset with the block 10, so that the block 10 will be engaged with the inner wall of the slot 12, thereby completing the fixation of the shell 4. When the equipment is impacted, the shell sleeve 17 will slide on the outside of the sliding column 15. At this time, the limit column 16 slides on the inner wall of the slide groove 18, so that when the shell sleeve 17 slides in the shell sleeve 17, the limit column 16 will squeeze the spring 2 19, so that the spring 2 19 will deform and generate elastic potential energy, so that the impact generated by the equipment can be absorbed, thereby reducing the impact of the impact on the equipment.
