The invention has the working principle and advantages that: when the college student English translation learning auxiliary device is used, the working process is as follows:

as shown in fig. 1, when the three placing plates 4 need to be unfolded, the rotating disc 13 drives the rotating shaft 14 to rotate, so that the rotating shaft 14 drives the screw 15 to rotate, the screw 15 drives the two threaded sleeves 16 to be close to each other through the threaded transmission, so that the threaded sleeves 16 drive the corresponding second slide bars 7 to move downwards through the first connecting rods 12, as shown in fig. 2 and 3, the downward movement of the second slide bars 7 applies downward pulling force to the lower ends of the second connecting rods 19, so that the included angle of the second connecting rods 19 is reduced, so that the second connecting rods 19 apply pulling force to the two lower ends of the first shearing rod group 20, further, the length of the first shearing rod group 20 in the vertical direction is increased, and then, the length of the second shearing rod group 21 and the third connecting rods 22 in the vertical direction is also increased, so that the rotation center distance of the third placing plates 4 is increased, and then the three placing plates 4 rotate at the same time of pulling distance under the action of the connecting pieces 3, so that the three placing plates 4 tend to the same plane device, and the three placing plates are placed on the same plane, and the same plane 4 are completely placed at the same place plate 4, and the side of the same place plate 4 is completely when the same plane is placed, and the elastic force is applied to the three placing plates 4 is completely, and the three placing plates are placed on the side 6 when the plane 4 are completely, and the side of the plane is completely placed.

After learning, the rotating shaft 14 is driven to reversely rotate by the reverse rotating turntable 13, so that the rotating shaft 14 drives the screw rod 15 to reversely rotate, the screw rod 15 drives the two screw sleeves 16 to be mutually far away through screw transmission, the screw sleeve 16 drives the corresponding second slide rod 7 to move upwards through the first connecting rod 12, the upward movement of the second slide rod 7 applies upward thrust to the lower ends of the two connecting rods 19, the included angle of the two connecting rods 19 is increased, the two connecting rods 19 apply thrust to the two lower ends of the first scissor rod group 20, the length of the first scissor rod group 20 in the vertical direction is reduced, the lengths of the second scissor rod group 21 and the two connecting rods three 22 in the vertical direction are also reduced, the rotating center distance of the three placing plates 4 is reduced, and because the side edge of the lower side position placing plate 4 is acted by the restoring force of the elastic pull rope 6 at any time, the situation that when the rotation center distance of the three placing plates 4 is about to be reduced, the three placing plates 4 are blocked due to dead point states is avoided, the three placing plates 4 can be smoothly stored, when the dead point states of the three placing plates 4 are destroyed, the three placing plates 4 are reversely rotated when the distance is pulled away by matching with the action of each connecting sheet 3, the three placing plates 4 tend to be in a mutually parallel and close stacking state, when the three placing plates 4 are mutually parallel, the folding storage of the three placing plates 4 is completed, the operation is simple and convenient, the occupied space is reduced after the storage, the carrying management is convenient, the technical problems that the translation books, the writing record books, the auxiliary mutual dictionary and other tools are inconvenient to be placed when the current college students perform English translation study are solved, thereby being beneficial to improving the English translation capability of college students.

As described above, in the unfolding process of the three placement boards 4, the two threaded sleeves 16 synchronously drive the two first struts 11 to approach each other, and make the two first struts 11 squeeze the bellows 17, because the conducting direction of the first check valve 9 points to the first air pipe 8, and the conducting direction of the second check valve 10 points to the inside of the bellows 17, 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 placement board 4 appears through the air holes 24, so that dust adhered to the surface of the placement board 4 is blown away, and the cleanness and sanitation during learning are maintained.

In the process of accommodating the three placement boards 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 a suction force is generated in the corrugated pipe 17, and the suction force sucks external air into the corrugated pipe 17 through the second check valve 10, thereby realizing automatic air storage, and blowing away dust adhered to the surface of the placement board 4 when the placement board 4 is used next time.

As shown in fig. 5 and 6, in the process of unfolding the three placement plates 4, a pulling force is applied to the upper ends of the two first slide bars 26 through the hinge shafts of the two third links 22, so that the two first slide bars 26 are pulled out of the corresponding first slide cylinders 25 and the included angles become smaller, so that the included angles of the two fourth links 28 become smaller, the fourth links 28 drive the corresponding circular discs 29 to rotate, so that the pressure applied by the circular discs 29 to the third slide bars 31 is gradually increased, so that the pressure applied by the third slide bars 31 to the first slide bars 34 through the springs 32 is gradually increased, further, the damping applied by the friction columns 34 to the first slide bars 26 is gradually increased, and when the three placement plates 4 are completely unfolded, the first slide bars 26 cannot slide in the first slide cylinders 25 under the damping of the friction columns 34, so that the three placement plates 4 are supported and stabilized when the three placement plates 4 are unfolded and used.

In the process of accommodating the three placement plates 4, pressure is applied to the upper ends of the two first slide bars 26 through the hinge shafts of the two third connecting bars 22, so that the two first slide bars 26 retract into the corresponding first slide cylinder 25 and the clamping angle becomes large, the included angle of the two fourth connecting bars 28 also becomes large, the fourth connecting bars 28 drive the corresponding circular discs 29 to reversely rotate, the pressure applied by the circular discs 29 to the third slide bars 31 is gradually reduced, the pressure applied by the third slide bars 31 to the friction columns 34 through the springs 32 is gradually reduced, and the damping applied by the friction columns 34 to the first slide bars 26 is further reduced, so that the three placement plates 4 are accommodated smoothly, and the fact that the three placement plates 4 are accommodated while simultaneously driving the first slide bars 26 and the first slide cylinder 25 to retract is realized.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
