The working principle and the advantages of the invention are as follows: this kind of university student english translation study auxiliary device is when using, and the course of work is as follows:

as shown in fig. 1, when three placing plates 4 need to be unfolded, the rotating shaft 14 is driven to rotate by rotating the rotary table 13, so that the rotating shaft 14 drives the screw rod 15 to rotate, the screw rod 15 drives the two screw sleeves 16 to approach each other through screw transmission, and the screw sleeves 16 drive the corresponding second slide rods 7 to move downwards through the first connecting rods 12, as shown in fig. 2 and 3, downward pulling force is applied to the lower ends of the second two connecting rods 19 by downward movement of the second slide rods 7, so that the included angle between the second two connecting rods 19 is reduced, and then the second two connecting rods 19 apply pulling force to the two lower ends of the first scissor rod group 20, so that the length of the first scissor rod group 20 in the vertical direction is increased, and so on, the lengths of the second scissor rod group 21 and the third connecting rods 22 in the vertical direction are also increased, so that the distances of the rotation centers of the three placing plates 4 are increased, and further, under the effect of each connecting piece 3, the three placing plates 4 are rotated while being pulled apart So that the three placing plates 4 tend to be in the same plane, and the side edges of the lower position placing plate 4 are rotated, the elastic pulling rope 6 is acted by force, so that the elastic pulling rope 6 obtains a restoring force, and when the three placing plates 4 are in the same plane, the complete opening of the three placing plates 4 is completed, so that the respective interpretation learning tools are placed on the placing plates 4 for use.

After learning is finished, the rotating shaft 14 is driven to rotate reversely by the reverse rotation of the rotating disc 13, so that the rotating shaft 14 drives the screw rod 15 to rotate reversely, the screw rod 15 drives the two screw sleeves 16 to be away from each other through thread transmission, so that the screw sleeves 16 drive the corresponding second slide rods 7 to move upwards through the first connecting rods 12, the upward movement of the second slide rods 7 applies upward thrust to the lower ends of the second connecting rods 19, so that the included angle between the second connecting rods 19 is increased, so that the two second connecting rods 19 apply thrust to the two lower ends of the first scissor rod group 20, so that the length of the first scissor rod group 20 in the vertical direction is reduced, and by analogy, the lengths of the second scissor rod group 21 and the two third connecting rods 22 in the vertical direction are also reduced, so that the distances of the rotation centers of the three placing plates 4 are reduced, and the side edges of the placing plate 4 at the lower side position are constantly subjected to restoring force of the elastic pull rope 6, thereby avoiding the three placing plates 4 from being blocked due to dead point when the distance of the rotating centers of the three placing plates 4 is about to be reduced, ensuring the smooth storage of the three placing plates 4, when the dead point state of the three placing plates 4 is destroyed, the three placing plates 4 rotate reversely while being separated by the action of each connecting piece 3, so that the three resting plates 4 tend to be in a stacked condition parallel to each other, when the three resting plates 4 are parallel to each other, the folding and the storage of the three placing plates 4 are completed, the operation is simple and convenient, the occupied space is reduced after the storage, the carrying and the management are convenient, thereby solve present university student and be not convenient for when carrying out english translation study to the technical problem that the apparatus such as translation books, writing record volume, supplementary translation dictionary were placed, and then help university student to the ability promotion of english translation.

As mentioned above, in the process of unfolding the three placing plates 4, the two screw sleeves 16 synchronously drive the two first support rods 11 to approach each other, and the two first support rods 11 extrude the bellows 17, because the conduction direction of the one-way valve one 9 is directed to the first air pipe 8, and the conduction direction of the two-way valve two 10 is directed to the inside of the bellows 17, the air in the bellows 17 is conveyed to the second air pipe 23 through the first air pipe 8, and then the corresponding surface of the placing plate 4 appears through the air holes 24, and dust adhered to the surface of the placing plate 4 is blown off, so as to keep the cleanness and sanitation during learning.

In the process of accommodating the placing plate 4, the two screw sleeves 16 synchronously drive the two first support rods 11 to be away from each other, and the two first support rods 11 stretch the corrugated pipe 17, so that suction force is generated in the corrugated pipe 17 and is used for sucking external air into the corrugated pipe 17 through the two check valves 10, and automatic air storage is realized, so that dust adhered to the surface of the placing plate 4 is blown off when the placing plate 4 is used next time.

As shown in fig. 5 and 6, during the unfolding process of the three placing plates 4, the upper ends of the two first sliding rods 26 are pulled by the hinge shafts of the two third connecting rods 22, so that the two slide bars one 26 are drawn out from the corresponding slide cylinders one 25 and the included angle is reduced, thereby the included angle of the two connecting rods four 28 is also reduced, and then the four connecting rods 28 drive the corresponding discs 29 to rotate, so that the pressure applied by the discs 29 to the three sliding rods 31 is gradually increased, so that the pressure exerted by the third sliding rod 31 on the friction column 34 by the spring 32 is gradually increased, so that the damping exerted by friction columns 34 on slide bar one 26 is gradually increased, when three of said resting plates 4 are fully unfolded, the first slide bar 26 cannot slide in the first slide cylinder 25 under the damping of the friction column 34, so that the two first slide bars 26 and the first slide cylinders 25 are used for supporting and stabilizing the three placing plates 4 when the three placing plates 4 are unfolded for use.

In the process of accommodating the three accommodating plates 4, pressure is applied to the upper ends of the two first sliding rods 26 through the hinge shafts of the two third connecting rods 22, so that the two first sliding rods 26 retract into the corresponding first sliding cylinders 25, the included angle is increased, the included angle of the two fourth connecting rods 28 is increased, the fourth connecting rods 28 drive the corresponding circular discs 29 to rotate reversely, the pressure applied to the third sliding rods 31 by the circular discs 29 is gradually reduced, the pressure applied to the friction columns 34 by the third sliding rods 31 through the springs 32 is gradually reduced, the damping applied to the first sliding rods 26 by the friction columns 34 is reduced, the three accommodating plates 4 are smoothly accommodated, and the first sliding rods 26 and the first sliding cylinders 25 are driven to be accommodated together when the three accommodating plates 4 are accommodated.
