[0040] It should be noted that the drive assembly 400 is mounted on the device using the mating plate 409 and bolts 410, and can also be disassembled for maintenance.

[0041] The working principle is as follows: Using this device requires a drive motor 404 to drive the lifting screw 103 to rotate, thereby controlling the position change of the movable slide plate 102 between the slide plate valve body 101 and the movable slide plate 102. The output of the drive motor 404 drives the ball drive sleeve 403 to rotate via the drive gear 405 and the driven gear ring 406. While rotating, the ball drive sleeve 403 drives the lifting screw 103 to rise and fall. The ball drive sleeve 403 is constrained by the annular groove 407 and the annular sleeve 408, maintaining its rotation in place. During the rising and falling process, the lifting screw 103 will cause changes in the bottom protective sleeve 200 and the top protective sleeve 300. In the bottom protective sleeve 200, the folding sleeve 201 will rise and fall accordingly. The lead screw 103 retracts or extends as it rises and falls. To facilitate daily maintenance and repair, a fitting block 204 is used to snap the connecting buckle 202 and the top cover 203 together. With the assistance of the handle 205, the connecting buckle 202 and the top cover 203 can be easily separated. In the top protective sleeve 300, the folding sleeve 301 retracts or extends as the lead screw 103 rises and falls. To facilitate daily maintenance and repair, a fitting block 304 is used to connect the connecting buckle 302 and the top cover 303 together. With the assistance of the handle 305, the connecting buckle 302 and the top cover 303 can be easily separated.
