[0033] In this embodiment, the lifting assembly includes two movable plates 10, which are slidably installed on the inner top surface of the support box 1, and the bottom surfaces of the two movable plates 10 are fixedly installed with inner movable seats 11. The top surface of the lifting plate 8 is fixedly installed with two inner fixed seats 12, and the two inner fixed seats 12 are rotatably installed with inner movable rods 13. The top ends of the two inner movable rods 13 are rotatably installed in the two inner movable seats 11 respectively. When the two movable plates 10 are close to each other, the lifting plate 8 will be driven to descend through the cooperation of the inner movable seat 11, the inner fixed seat 12, and the inner movable rod 13. After the lifting plate 8 is lowered to the moving position, the universal wheel 9 will contact the ground and lift the entire screw feeder body 2. At this time, the staff can push the pushing frame 19 to drive the support box 1 and the screw feeder body 2 to move through multiple universal wheels 9, thereby enhancing the convenience of the device when moving.

[0034] In this embodiment, the lifting assembly also includes a first screw rod 14, which is rotatably installed in the support box 1. The first screw rod 14 is provided with two sections of threads with opposite rotation directions. A motor A15 is fixedly installed on one side of the support box 1.
