[0061] Working principle:

[0062] When the displacement plate 10 is moved, one of the following two methods can be selected:

[0063] The first method: when the displacement plate 10 needs to move, the first displacement drive motor 12 is electrically connected to the external power supply to drive the first transmission bevel gear 13 to rotate, the rotation of the first transmission bevel gear 13 drives the meshing second transmission bevel gear 14 to rotate, the rotation of the second transmission bevel gear 14 drives the first transmission rotating shaft 15 to rotate, the rotation of the first transmission rotating shaft 15 drives the two displacement threaded rods 16 with opposite thread rotation directions to rotate, and the displacement plates 10 with corresponding threaded connections are driven to move by the two displacement threaded rods 16 with opposite thread rotation directions, so that the two displacement plates 10 move in opposite directions;

[0064] The second type: when the displacement plate 10 needs to move, the second displacement drive motor 25 is connected to the external power supply to drive the worm 26 to rotate, the rotation of the worm 26 drives the worm gear 27 to rotate, the rotation of the worm gear 27 drives the other second transmission rotating shaft 20 to rotate, wherein the rotation of the other second transmission rotating shaft 20 drives the other displacement transmission gear 21 and the second eccentric convex plate 23 to rotate at the same time, wherein the rotation of the other displacement transmission gear 21 drives the other moving rack 19 to move, wherein the movement of the other moving rack 19 drives the corresponding displacement plate 10 to move, and at the same time the second The rotation of the eccentric convex plate 23 drives the first eccentric convex plate 22 to rotate in the opposite direction to the second eccentric convex plate 23 through the connecting plate 24. The reverse rotation of the first eccentric convex plate 22 drives one of the second transmission rotating shafts 20 to rotate. The rotation of one of the second transmission rotating shafts 20 drives one of the displacement transmission gears 21 to rotate. The rotation of one of the displacement transmission gears 21 drives one of the moving racks 19 to move, so that the movement of one of the moving racks 19 is opposite to the movement direction of the other moving rack 19, and then the movement of one of the moving racks 19 drives the corresponding displacement plate 10 to move.

[0065] After the displacement plate 10 is moved, the clamping plate 11 is allowed to enter the interior of the slidingly connected rectangular beam 1, thereby fixing the position of the support shell 9 and adjusting the height of the lifting plate 29:
