The present invention includes a bottom plate having two opposing slots each allows a L-shaped clamping plate sliding therein. The clamping plate has one end vertically extended below the slots and exposed to form a clamping surface and another end extended horizontally in contact with the bottom plate to form a control surface. Two spacers are provided to confine the left and right sides of the control surface. The control surface has an aperture to couple with a lower end of a N-shaped control bar. The control bar has an upper end coupling with a lower end of a rotational rotative cover. The lower end of the rotative cover has a recess on the bottom to house the control bar, and a top portion to be coupled with a T-shaped wrench and driven thereof. Hence the clamping plate may be driven to synchronously clamp a lube filter.
