[0037] Working principle: The dual-axis motor 601 is electrically connected to the battery 7. When the staff needs to manage and store the hospital's information documents, they pull open the door panel 101 through the handle, and then put the documents to be stored on the top of the three carrying plates 2 according to their categories. After the placement is completed, one of the rockers 505 is rotated, and the rotation of the rocker 505 drives the two-way threaded rod 501 connected to it to rotate. The rotation of the two-way threaded rod 501 drives the two connecting plates 502 on its surface to approach each other. When the two connecting plates 502 move, they drive the two clamping blocks 504 on their surfaces to move. At the same time, the limit column 503 embedded at the other end of the connecting plate 502 limits itself. The two clamping blocks 504 on both sides stop rotating when they touch the documents, and use the other two clamping assemblies 5 to clamp the documents on the top of the other two carrier plates 2 in the same way.

When the staff needs to move the information document management cabinet, the dual-axis motor 601 is started by the external controller, and the dual-axis motor 6 The output ends on both sides of 01 rotate to drive the two connecting shafts 1 603 connected thereto to rotate. At the same time, the dual-axis motor 601 is supported by the connecting block 602, and the connecting shaft 1 603 is supported by the supporting ring 604. The rotation of the connecting shafts 1 603 on both sides drives the bevel gears 1 605 connected thereto to rotate synchronously. The rotation of the two bevel gears 1 605 drives the two bevel gears 2 606 meshing therewith to rotate. The rotation of the two bevel gears 2 606 drives the connecting shaft 2 607 and the two gears 608 connected thereto to rotate. The rotation of the four gears 608 drives the four tooth plates 609 meshing therewith to move downward. At the same time, the four limiting bars 103 limit the four grooves 3 610 so that they will not tilt. The tooth plate 609 moves downward, driving the universal wheel 611 to move downward at the same time, and when moving downward, the two side limit plates 104 limit the two side connection plates 612 to prevent the four tooth plates 609 from being separated, until the four universal wheels 611 are completely in contact with the ground, and the management cabinet body 1 is lifted upward, so that the bottom of the management cabinet body 1 is separated from the contact with the ground. At this time, the staff can push the management cabinet body 1 to move to the required position. After moving to the required position, the external controller controls the dual-axis motor 601 to reverse, so that the four universal wheels 611 can be retracted and stored again. This method is more convenient when the file cabinet needs to be transferred, and does not require multiple people to assist in the transportation, saving time and effort.
