[0033] When working, firstly, one side of the electronic product is pressed against the plate 2, and then the second servo motor 29 is started. The second servo motor 29 drives multiple active bevel gears 31 to rotate through the transmission shaft 30. The active bevel gear 31 drives the driven bevel gear 28 meshing with it to rotate.
