[0028] In the utility model, the working steps of the device are as follows:

[0029] The hardware to be processed is placed in the turntable, and the rotating plate 24 rotates so that the hardware enters the conveying rail 26 through the guide 25. After falling into the placement groove 28 through the conveying rail 26, the upper fixed plate 1 remains stationary, and then the first transmission wheel 2 is controlled to rotate by the motor, and the second transmission wheel 4 is driven by the transmission belt 3. The rotation of the second transmission wheel 4 will cause the transmission threaded rod 5 on the lower surface to start rotating.
