[0024] Furthermore, the medical staff places the scanning head of the dental scanner in the placement box 5, presses the movable baffle 6 on the protective side plate 4, so that the two movable baffles 6 gradually approach each other, and the magnetic strips 8 on the two movable baffles 6 are mutually attracted to complete the fixing of the movable baffle 6, and tightens the fastening bolts 9 so that the fastening bolts 9 gradually squeeze the movable rod 10, thereby fixing the connecting frame 7 on the movable rod 10 to prevent the connecting frame 7 from rotating on the movable rod 10. At this time, the cart body 1 is moved, and the cart body 1 drives the dental scanner, thereby driving the dental scanner to the specified position. During the movement of the cart body 1, the scanning head is placed on the cart The side end of the main body 1 is easily hit, and the protective baffle 3, the protective side plate 4 and the movable baffle 6 directly above the placement box 5 can protect the scanning head, thereby protecting the upper half that is not in the placement box 5. If the dental scanner collides with an object, the protective baffle 3, the protective side plate 4 and the movable baffle 6 protect the scanning head to prevent the foreign object from hitting the scanning head, thereby causing the scanning head to fall from the falling placement box 5 or the scanning head to be damaged. At the same time, when the placement box 5 is hit, the buffer plate 11 between the fixed bracket 12 and the placement box 5 can provide a buffering effect to further prevent the scanning head in the placement box 5 from being damaged; The dental scanner moves to the designated position. When the medical staff needs to use the scanning head, they apply external force to the protective side panels 4 to separate the two protective side panels 4, rotate the protective side panels 4 on both sides of the protective baffle 3, so that the protective baffle 3 and the protective side panels 4 on both sides are 180 degrees, loosen the fastening bolts 9, rotate the protective baffle 3, and the protective baffle 3 drives the connecting frame 7 to rotate on the outer wall of the movable rod 10, so that the protective baffle 3 and the protective side panels 4 gradually move into the storage groove 16, move the movable baffle 6, and move the movable baffle 6 on the protective side panels 4 until the movable baffle 6 moves into the placement groove 17. When the protective baffle 3, the protective side panels 4 and the movable baffle 6 are completely moved into the storage groove 16, move the partition 18, so that the block 19 on the partition 18 is gradually inserted into the card slot 20, and the block 19 contacts the inclined surface of the card plate 21, so that the block 19 drives the card plate 21 to compress the first spring 23. When the block 19 is completely moved into the card slot 20, the first spring 23 To restore the original state, the first spring 23 drives the card plate 21 to reset. At this time, the card plate 21 locks the card block 19, thereby completing the fixation of the partition 18. The protective component can be stored through the storage slot 16 to prevent the protective component from affecting the use of the scanner. The storage slot 16 is closed by the partition 18, so that medical items can be placed on the placement rack 2 and the partition 18, ensuring the placement space of the items, preventing the protective component from affecting the space on the placement rack 2, and also protecting the protective component; when the protective component needs to be used, it is only necessary to move the operating panel 22, and the operating panel 22 drives the card plate 21 to compress the first spring 23, so that the card plate 21 no longer blocks the card block 19. At this time, the partition 18 can be moved, and the protective baffle 3 and the protective side plate 4 are rotated to make the protective baffle 3 perpendicular to the placement rack 2, and the protective baffle 3 is perpendicular to the protective side plate 4, and then the two movable baffles 6 are fitted together, thereby completing the protection of the scanning head by the protective component.

The side wall of the buffer pad 24 is fixedly connected to the placement rack 2, and the outer wall of the buffer rack 26 is symmetrically fixedly connected to the buffer rod 37, and the inner wall of the placement rack 2 is symmetrically fixedly installed with the first pressure plate 27, the first pressure plate 27 is in the storage groove 16, and the outer wall of the buffer rod 37 is movably mounted with the first pressure plate 27, and the side wall of the buffer rod 37 is fixedly connected with the second pressure plate 29, and the side wall of the first pressure plate 27 is fixedly connected to the second spring 28, and the side wall of the second spring 28 is fixedly connected to the second pressure plate 29, and the second spring 28 is movably mounted on the outer wall of the buffer rod 37.

[0026] Further, the movable baffle 6 is moved to gradually bring the two movable baffles 6 closer together, the magnetic strips 8 are attracted to each other, the two movable baffles 6 are connected together, the fastening bolts 9 are rotated to squeeze the movable rod 10, and the connecting frame 7 is fixed on the movable rod 10, so that the protective assembly can protect the scanning head.

The bottom of the outer wall of the third spring 41 is fixedly connected to the second inclined block 40, the outer wall of the second inclined block 40 is movably covered with a displacement block 42, the side wall of the displacement block 42 is fixedly connected to the fourth spring 44, the side wall of the fourth spring 44 is fixedly connected to a movable baffle 6, the inner wall of the movable baffle 6 is provided with an inclined panel 39, the movable baffle 6 is movably covered on the outer wall of the rotating screw rod 38, the side wall of the rotating screw rod 38 is fixedly connected to the rotating key 13, the outer wall of the rotating screw rod 38 is connected to the plug block 35 through a thread, the outer wall of the plug block 35 is movably covered with the movable baffle 6, the plug block 35 A first inclined block 36 is fixedly connected to the top of the outer wall; a limit block 30 is symmetrically arranged in the protective side plate 4, and a limit groove 31 is symmetrically provided on the outer wall of the movable baffle 6. The limit block 30 is embedded in the inner wall of the limit groove 31, and a ball 32 is movably installed in the limit block 30, and the ball 32 is in contact with the movable baffle 6. A first slot 33 is provided in the side wall of the movable baffle 6, and the rotating screw 38 is located in the first slot 33. A second slot 34 is provided in the side wall of the movable baffle 6, and the inclined panel 39 and the second inclined block 40 are located in the second slot 34.

[0028] Further, the two movable baffles 6 are moved, and the movable baffles 6 drive the limit grooves 31 to move. The limit grooves 31 move on the outer wall of the limit block 30, and the limit block 30 limits the moving range of the movable baffle 6. The ball 32 reduces the friction between the protective side plate 4 and the movable baffle 6, so that the two movable baffles 6 gradually approach each other, and the magnetic strips 8 are attracted to each other, so that the two movable baffles 6 are connected together, and the fastening bolts 9 are rotated to squeeze the movable rod 10. By rotating the rotating key 13 on the side of one of the movable baffles 6 in the positive direction, the rotating key 13 drives the rotating screw 38 to rotate, and the rotating screw 38 drives the insert block 35 to move in the first slot 33, so that the insert block 35 drives the first inclined surface block 36 to gradually move out of the first slot 33, and the first inclined surface block 36 gradually moves to the second slot 34 in the other movable baffle 6, and the first inclined surface block 36 gradually approaches the second inclined surface block 40 in the other movable baffle 6, and the first inclined surface block 36 The inclined surface of the first bevel block 36 gradually contacts the inclined surface of the second bevel block 40, so that the first bevel block 36 drives the second bevel block 40 to gradually compress the third spring 41, and the first bevel block 36 continues to move. When the first bevel block 36 cannot continue, the third spring 41 returns to its original state, and the third spring 41 drives the second bevel block 40 to reset, so that the second bevel block 40 locks the first bevel block 36. Through the same steps, the rotating key 13 on the side of another movable baffle 6 is operated. When the protective component is collided, if the external force generated by the collision is too large, the magnetic strips 8 on the two movable baffles 6 are not enough to keep the two movable baffles 6 connected together. At this time, the fourth spring 44 elastically pushes the second bevel block 40 to block the first bevel block 36, thereby avoiding the separation of the two movable baffles 6, thereby ensuring the stability of the protective component and avoiding the separation of the protective component caused by the excessive external force generated by the collision, thereby losing the protective effect on the scanning head; If the protective component needs to be stored, it is only necessary to reversely rotate the rotating key 13 on the side of the movable baffle 6 so that the rotating key 13 drives the rotating screw 38 to rotate, and the rotating screw 38 drives the insert block 35 and the first inclined surface block 36, the first inclined surface block 36 drives the second inclined surface block 40, and the second inclined surface block 40 drives the displacement block 42 to move on the cylinder 43. The cylinder 43 compresses the fourth spring 44, so that the second inclined surface block 40 gradually approaches the inclined surface plate 39. After the inclined surface of the second inclined surface block 40 contacts the inclined surface of the inclined surface plate 39, the second inclined surface block 40 moves along The inclined surface of the inclined panel 39 moves, so that the second inclined surface block 40 compresses the third spring 41, so that the second inclined surface block 40 no longer blocks the first inclined surface block 36. When the first inclined surface block 36 and the insert block 35 are completely moved back to the first slot 33, the movable baffle 6 can be separated to continue to protect the storage of the component. Since there is a certain distance between the second inclined surface block 40 and the inclined surface panel 39, when the rotating key 13 is slightly loosened, the second inclined surface block 40 will not contact the inclined surface panel 39, so that the second inclined surface block 40 can still block the first inclined surface block 36.
