[0012] The utility model has the following beneficial effects:

[0013] (1) The utility model passes the push rod through the hole in the middle of the oil box so that the connecting plate and the mounting plate are abutted, and then the connecting mechanism and the lubrication structure can be installed on the mounting plate by connecting a plurality of hexagon socket bolts with the second thread groove and the first thread groove. Then, the lubricating oil is poured into the interior of the oil box by unscrewing the threaded cover. When the push rod moves, a plurality of ball bearings are driven by the push rod to roll inside the mounting groove, thereby rolling the lubricant to the surface of the push rod, thereby achieving the effect of convenient maintenance and relatively improving practicality.

[0014] (2) The utility model starts the micro electric push rod to drive the partition to slide on the slide rod, thereby reducing the internal space of the oil box, thereby avoiding the situation where the ball at the top cannot roll out the oil due to the low lubricating oil level.
