ABSTRACT:
A toggle joint band wrench for an oil filter; comprises: A pair of side connectors bases which have three functional sets of systems connected between them to combine in functioning as a device. They are: (a) A set of toggle joint mechanisms connected pivotally between the upper parts to support the central toggle joint and its top handle on the top center of the device. (b) A clamping means connected between the middle pans to function for moving the side connectors closer or away from each other. (c) A pair of curved, laminated, toothed, clamping bands connected between the lower parts with a circular opening for an oil filter to be placed in-between them. A handle is connected to the top of the toggle joint pivotally. The clamping means can be adjusted to move the bands closer to each other in clamping and locking onto the oil filter. The toggle joint system keeps the handle constantly centralized. The handle can be flipped to be set on a lateral position in two positions across from each other. The handle also has a hexagon nut connected on the bottom end. The handle can be set to stand up at a 90 degree angle in relative to the clamping means and serves as an extension for a socket wrench to connect to the hexagon nut in driving the band wrench to rotate around.
