The device has a simple structure, can effectively improve the feeding efficiency, and reduce labor costs.

[0083] One end of the second screw 551 is driven to rotate by the driver 553, and the other end is connected to the bearing seat 571 on the outer wall of the sleeve 570; wherein the driver 553 can be a hand wheel or a motor. A bearing is installed in the bearing seat 571 to ensure that the second screw 551 and the sleeve 570 are smoothly connected in rotation. The second screw 551 is driven to rotate by the driver 553, thereby driving the sleeve 570 to rise and fall, thereby achieving precise control of the sleeve 570. This design not only improves work efficiency, but also reduces labor costs. At the same time, due to the use of bearings, the service life of the device is greatly extended and the maintenance frequency is reduced.
