When the first rotating rod 8 rotates, it can drive the cam 10 to rotate. The cam 10 can be rotated to the surface of the connecting strip 21 and squeezed, so that the connecting strip 21 can drive each connecting tube 12 to move, so that the sponge 16 inside the connecting tube 12 can be moved to the bottom end of the fixed tube 11 and squeezed, so as to squeeze out the lubricating oil inside the sponge 16, so that the lubricating oil can drip through the outlet end of the connecting tube 12 onto the designated chain or sprocket for lubrication and protection. The top of the base 1 is provided with a plurality of mounting grooves for connecting the support rods on the compact cabinet, and then connecting each partition and side panel to the surface of the support rod.
