Abstract
According to the present invention, the oil filter replacement device has a number of pins for clamping an oil filter, and the pins are extended eccentrically from corresponding secondary gear members. The secondary gear members are engaged to spin simultaneously by a main gear member. As such, the pins could be adjusted to fit on oil filters of various sizes. Additionally, each pin is rotatable and has at least a flat face. As the pins rolls along the circumference of the oil filter, their flat faces are turned to interface the flat faces around the oil filter. As such, the oil filter is tightly and reliably clamped by the oil filter replacement device, thereby preventing the problem of uneven exertion of force and deforming the oil filter.
