An oil core wrench includes a oneway control unit, a wrench unit and a rotation handle. The wrench unit includes a threaded rod, an adjusting member, a base member and a clamping member. The oneway control unit is mounted in the base member and includes a control member. Thus, the oil core is clamped between the clamping member of the wrench unit and the control member of the oneway control unit so that the wrench unit can drive the oil core to rotate successively in a oneway manner by operation of the oneway control unit, so as to tighten or loosen the oil core easily and quickly. In addition, the oil core wrench can be operated in a narrow or small working region.

The present invention provides an oil filter sleeve. The oil filter sleeve provides a clean and safe method of removing an oil filter from the underside of a vehicle. The oil filter sleeve comprises a hollow cylindrical sleeve that removably attaches over an oil filter installed on a vehicle. The sleeve has an accordion like construction adapted to extend and retract in accordance with the size of the oil filter. Once the sleeve encloses the oil filter, a user may remove the oil filter from the vehicle and the oil filter sleeve will catch and hold any excess oil that leaves the oil filter. In this way, the oil filter sleeve prevents oil leakage and spillage.

An oil filter removal and drain system including an oil-filter-removal assembly and a drain-attachment assembly in functional combination. The oil-filter-removal assembly includes a top-frame, a bottom-frame, a geared-socket-hub, a filter-socket, a plurality of geared-clamp-jaws, a filter-gasket, and a toggle-clamp in functional and structural combination. The drain-attachment assembly includes a drain-attachment-body, a drain-toggle-clamp, a drain-nipple, and a filter-cutter. The drain-attachment assembly is removably affixable to the oil-filter-removal assembly via the plurality keyhole-stud-receivers of the drain-attachment assembly accepting and retaining the plurality of keyhole-studs of the oil-filter-removal assembly. An oil-filter-removal assembly may be used on many different types of fluid filters (e.g., hydraulic fluid, diesel fuel, engine oil, etc.).

A wire brush, a side-post wrench, and a top-post wrench which are capable of pivoting coaxially around the upper end of the device to be concealed within the handle comprises an all-in-one battery maintenance device. The lower end provides a heavy, solid base which may be safely used to tap the battery cables into the proper position on the posts of a top-post battery.

Embodiments described herein relate to a tool comprising a cylindrical member having a cylindrical tube portion with a circular opening at a first end of the cylindrical member, and a protrusion disposed on an inner surface of the cylindrical tube portion. In various embodiments, the tool includes a plurality of protrusions that are disposed equal-distant from one another along a circumference on the inner surface of the cylindrical tube portion. In various embodiments, the cylindrical member comprises a second cylindrical tube portion with a second circular opening on a second end of the cylindrical member. In various embodiments, the protrusion has a varying height that gradually increases from a first end of the protrusion to a second end. In various embodiments, the protrusion is disposed at a slanted angle with respect to the circular opening where the first end is closer to the circular opening than the second end.

A wrench for automotive service, and in particular for service involving oil filters. The wrench comprises a torque head, torque handle, and a bracing member. The bracing member engages with the torque head to position the wrench with respect to a target body, such as an oil filter. The torque handle engages with the torque head to transfer torque from the torque handle to the torque head. The torque head is configured to transfer torque to the target body via grip surface. Additional features may provide additional functionality.

An oil filter-used apparatus includes a cover and multiple collars in different sizes. The cover is used for engagement with an external torque tool and includes an annular wall. The multiple collars are used for engagement with oil filters in different size. One of the collars is selected for connecting one of the oil filters to the annular wall.
