It includes a base, and a rectangular card slot is opened in the middle position of the rear end surface of the base, and the inner end surface of the card slot is opened with two threaded holes. The setting of the scale lines around the placement slot can ensure that the document to be scanned is directly under the scanner according to the numbers of the scale lines, which is convenient for the scanner to scan the text on the surface of the document. In addition, a suction cup is fixedly installed at the lower end of the footrest, and the suction cup fits tightly with the desktop, which can improve the stability of the base and prevent the base from shaking when it is subjected to external force.

At the same time, the scale lines cannot ensure that the document can be placed in the center at one time. If the subsequent scanner fails to scan, the position of the document needs to be adjusted again, and the document cannot be adjusted accurately. At the same time, the surface of the document will be uneven when it is placed. In this case, the scanner cannot perform the scanning operation, which limits the overall operation.

When the document is placed on the surface of the placement plate at random, the design can adjust the position of the document at one time so that the document can be centered on the lower surface of the scanner body. At the same time, during the adjustment of the document, the first flattening block and the second flattening block can move on the surface of the document to flatten the wrinkled and bulging parts of the document surface. Finally, the first flattening block and the second flattening block limit the position of the document on the left and right surfaces of the upper end of the document.

When the document is placed on the surface of the placement plate 1 at random, the design can adjust the position of the document at one time so that the document can be placed in the center of the lower surface of the scanner body 8. During the adjustment of the document, the first flattening block 36 and the second flattening block 40 can move on the surface of the document to flatten the wrinkles and bulges on the surface of the document. Finally, the first flattening block 36 and the second flattening block 40 limit the position of the document on the upper left and right surfaces of the document.

[0040] A method for using a scanner that is easy to inspect and maintain:

[0041] S1. First, place the document to be scanned on the surface of the placement plate 1, then start the servo motor 9, the servo motor 9 drives the bidirectional screw 10 to rotate, the bidirectional screw 10 drives the first sliding block 11 and the second sliding block 12 to move to opposite positions, the first sliding block 11 drives the first moving contact plate 13 to move to the back, the second sliding block 12 drives the second moving contact plate 14 to move forward, when the second moving contact plate 14 moves, it will drive the first connecting plate 17 and the first mounting rack plate 18 to move, and when the first mounting rack plate 18 moves, it will contact the rack plate 17. On the lower surface of the wheel column 23, the gear column 23 is meshed with the first mounting rack plate 18. At this time, the gear column 23 rotates, and the gear column 23 drives the transmission mechanism 24 to rotate. The transmission mechanism 24 drives the rotating cylinder 25 to rotate. At this time, the protruding column 27 moves inside the arc groove 26, thereby driving the moving rod 28 inside the rotating cylinder 25 to move forward, and then the moving rod 28 drives the contact head 29 to move to the right. At this time, the contact head 29 just contacts the moving first moving contact block 16, and the first moving contact block 16 squeezes the first telescopic cylinder 15 to continue to move to the right;

[0042] S2. The first moving contact block 16 will contact the left side of the file. Similarly, the first moving contact plate 13 will also drive the second connecting plate 20 and the second mounting rack plate 21 to move when moving. At this time, the second moving contact block 19 will also complete the operation of the first moving contact block 16. At this time, the second moving contact block 19 will contact the right side of the file. At the same time, the first moving contact plate 13 and the second moving contact plate 14 can respectively contact the front and rear surfaces of the file to quickly adjust the file to the center;

[0043] S3. When the bidirectional screw 10 rotates, it will also drive the first bevel gear assembly 30 and the second bevel gear assembly 38 to rotate. When the first bevel gear assembly 30 rotates, it will drive the rotating shaft 31 to rotate. The rotating shaft 31 drives the rotating gear 32 to rotate. The rotating gear 32 is meshed with the movable rack plate 33. The movable rack plate 33 will move toward the back, and then the movable rack plate 33 will drive the convex plate 34 to move toward the back. The convex plate 34 will respectively drive the first stabilizing bar 35, the first flattening block 36 and the first elastic block 37 to move toward the back. Similarly, the second stabilizing bar 39, the second flattening block 40 and the second elastic block 41 will also move forward. Through the movement of the first flattening block 36, the first elastic block 37, the second flattening block 40 and the second elastic block 41, the placed documents can be flattened and limited. Similarly, the upper surface and the left and right surfaces of the documents can complete the above operations at the same time.

[0044] S4. When performing inspection and maintenance, first start the telescopic rod 4, which will lift the connecting block 6 from the inside of the mounting frame 3. Then rotate the connecting block 6 on the outer surface of the threaded tube 5, remove the connecting block 6 from the inside of the threaded tube 5, and then perform inspection and maintenance operations on the connecting cross plate 7 and the scanner body 8.

[0045] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device, first place the document to be scanned on the surface of the placement plate 1, then start the servo motor 9, the servo motor 9 drives the bidirectional screw 10 to rotate, the bidirectional screw 10 drives the first sliding block 11 and the second sliding block 12 to move to opposite positions, the first sliding block 11 drives the first moving contact plate 13 to move to the back, the second sliding block 12 drives the second moving contact plate 14 to move forward, and when the second moving contact plate 14 moves, it will drive the first connecting plate 17 and the first mounting gear When the strip plate 18 moves, the second moving contact plate 14 will also drive the first moving contact block 16 to move. At the same time, when the first installed rack plate 18 moves, it will contact the lower surface of the gear column 23. The gear column 23 is meshed with the first installed rack plate 18. At this time, the gear column 23 rotates, and the gear column 23 drives the transmission mechanism 24 to rotate. The transmission mechanism 24 drives the rotating cylinder 25 to rotate. At this time, the convex column 27 will move inside the arc groove 26, thereby driving the moving rod 28 inside the rotating cylinder 25 to move forward, and then the moving rod 28 will drive the contact head 29 to move to the right. At this time, the contact head 29 is The first moving contact block 16 will squeeze the first telescopic tube 15 to continue to move to the right. At the same time, a contact spring is arranged inside the first telescopic tube 15. When the first moving contact block 16 is not squeezed by the contact head 29, the first moving contact block 16 will automatically return to its original position through the design of the contact spring. When the first moving contact block 16 contacts the left side of the file, the first moving contact plate 13 will also drive the second connecting plate 20 and the second mounting rack plate 21 to move when moving, and will also drive the second moving contact block 19 to move. At this time, the second moving contact block 19 similarly completes the operation of the first moving contact block 16. At this time, the second moving contact block 19 will contact the right side of the document. At the same time, the first moving contact plate 13 and the second moving contact plate 14 can contact the front and back surfaces of the document respectively, and the document can be quickly adjusted to the center. The design of the first moving contact plate 13, the second moving contact plate 14, the first moving contact block 16 and the second moving contact block 19 can respectively contact the front, back, left and right side surfaces of the document at the same time, and the document can be placed in the center at one time, so that the document is placed directly below the scanner body 8;

[0046] When the bidirectional screw 10 rotates, it will also drive the first bevel gear assembly 30 and the second bevel gear assembly 38 to rotate. When the first bevel gear assembly 30 rotates, it will drive the rotating shaft 31 to rotate, and the rotating shaft 31 will drive the rotating gear 32 to rotate. The rotating gear 32 is engaged with the moving rack plate 33, and the moving rack plate 33 will move to the back side, and then the moving rack plate 33 will drive the convex plate 34 to move to the back side, and the convex plate 34 will respectively drive the first stabilizing bar 35, the first flattening block 36 and the first elastic block 37 to move to the back side. Similarly, the second stabilizing bar 39, the second flattening block 40 and the second elastic block 41 will also move forward. The first flattening block 36, the first elastic block 37, the second flattening block 40 and the second elastic block 41 can flatten and limit the placed documents. Similarly, the upper and left surfaces of the documents can complete the above operations at the same time. If the first flattening block 36 continues to move after the first elastic block 37 and the second elastic block 41 collide, the positions of the first elastic block 37 and the second elastic block 41 are elastic, so that the rotating shaft 31 and the second elastic block 41 can be compressed until the first moving contact plate 13, the second moving contact plate 14, the first moving contact block 16 and the second moving contact block 19 After respectively contacting the outer surface of the document, the servo motor 9 stops moving. When the initial position of the first flattening block 36 or the second flattening block 40 is not on the upper side surface of the document, the first moving contact plate 13, the second moving contact plate 14, the first moving contact block 16 and the second moving contact block 19 respectively contact the document to move. At this time, the lower surfaces of the first flattening block 36 and the second flattening block 40 will fit the upper surface of the document. When the document continues to move, the first flattening block 36 and the second flattening block 40 will slide on the surface of the document, so that the surface of the document can be flattened. At the same time, the first flattening block 36 and the second flattening block 40 will slide on the surface of the document. The flattening block 36 and the second flattening block 40 are respectively installed on the upper left and right surfaces of the document, and can limit the position of the document. When the document is placed randomly on the surface of the placement plate 1, the position of the document can be adjusted at one time so that the document can be centered on the lower surface of the scanner body 8. At the same time, during the adjustment of the document, the first flattening block 36 and the second flattening block 40 can move on the surface of the document to flatten the wrinkled and bulging parts of the document surface. Finally, the first flattening block 36 and the second flattening block 40 limit the position of the document on the upper left and right surfaces of the document. The above is all the working principles of the present invention.
