A tool for the removal or installation of a fuse includes a first tool arm and a second tool arm pivotally mounted to the first tool arm about an axis. A second fuse holder spreader finger section is movable away from a first fuse holder spreader finger section and a second fuse pusher finger section is movable toward a first fuse pusher finger section in response to a first handle section being moved toward a second handle section.

A cold knife holder capable of pushing and pulling operations, includes a main body forming a chamber and a slot, a handle, a detent member, a first spring and a first steel ball. One side of the main body forms a perforation which communicates with the chamber. The handle includes a sleeve, a connecting rod and a grip rod. Both ends of the connecting rod are respectively connected to the sleeve and the grip rod, and the sleeve is pivotally sleeved on the main body, so that the handle is rotated relative to the main body, and the first or second caulking is connected to the perforation, and the detent member is arranged in the chamber. The first steel ball is pivotally embedded in the perforation, so that the detent member drives the first steel ball to be embedded in the first or second caulking, thereby positioning the handle.

A steering wheel cover manipulating device for installing and removing a steering wheel cover includes a bar, which is flat. The bar is arcuate proximate to a first end thereof defining a linear section of the bar and a tool head. The tool head is substantially semicircularly shaped when viewed from a respective opposed side of the bar. The tool head is substantially complementary to a cross-sectional segment of a steering wheel. The linear section can be grasped in a hand of a user so that the user is positioned to position the tool head between a steering wheel cover and the steering wheel. The tool head can be slid along an interface of the steering wheel cover and the steering wheel to facilitate installation and removal of the steering wheel cover.

A tool is disclosed for installing a roller tappet in a bore of the cylinder head of an internal combustion engine. The tool includes an elongated body and a connection head arranged at one end of the elongated body and configured to be at least in part inserted into an opening of the roller tappet. The tool further includes at least one reversible constraining element of the connection head to the roller tappet.

A power tool has a handle, a tool body, a rotator, a first working unit, and a second working unit. The handle has a handle body, a mounting ring rotatably mounted around the handle body, and a switch mounted on the mounting ring and inserted into the handle body. The tool body is mounted on the handle. The rotator is mounted in the tool body, and has a first driving end and a second driving end. The first working unit is mounted in the tool body, and is mounted around and engaged with the rotator. The second working unit is mounted in the tool body, and is mounted around and engaged with the rotator.

A wheel hub removal tool is provided that allows a single technician to readily remove the hub using the vehicle steering. The tool is a generally U-shaped bracket that is seated on the ball-joint to support a pair of arms on opposite sides of the U-joint assembly. The arms carry corresponding blocks that are sized to seat between the drive axle housing and a component of the U-joint that is coupled to the wheel hub. The tool maintains a block on either side of the U-joint assembly so that pressure may be applied alternatively between the blocks to gradually dislodge the wheel hub from the axle. The tool is adjustable to accommodate different axle hub and bearing assembly configurations for different vehicles.
