A wrench with a movable mallet platform is proposed. The wrench with a movable mallet platform includes a wrench main body and a mallet platform. The wrench main body includes a shaft. The shaft includes at least one abutment surface. The mallet platform is slidably sleeved on the wrench main body, and includes at least one striking portion and two holding portions. An engagement surface extends toward the shaft from at least one striking portion, and the engagement surface abuts against the at least one abutment surface. The two holding portions are disposed opposite to each other, and each of the two holding portions is connected to the at least one striking portion. Thus, the wrench with a movable mallet platform of the present disclosure can be struck by a striking tool, thereby fastening or releasing a fastening member.

The invention relates to a screwing device (1) with two tools (2, 3) for producing or releasing a screw connection between two fastening elements (10, 11). For a simple and compact structure of the screwing device (1), the invention provides that the tools (2, 3) are during the operation of the screwing device (1) connected to one another for rotation about common rotation axes (D1, D2).

An open-end wrench includes a stationary jaw including an inclined hole, a through hole adjacent to a first end of an interior surface and communicating with the inclined hole, and a forward hook; a handle pivotably secured to a rear end of the stationary jaw; and a moveable jaw including a forward hook; a hollow cylinder extending from a rear portion to dispose in the inclined hole, the hollow cylinder having an elongated slot on a surface and communicating with an interior of the hollow cylinder, and internal threads at an open end of the hollow cylinder; a biasing member disposed in the hollow cylinder, a threaded fastener secured to the internal threads to urge against a first end of the biasing member; and a pin inserted through the through hole and the elongated slot to stop at a second end of the biasing member.

A customized tool adapter that allows for a typical wrench to be connected temporarily, but with great stability to a typical ratchet. Such an application is capable of being used with several types wrenches and ratchets, including various sizes, units of measurement and other applications and is generally hexagonal in nature having swaged gripping lips.

A tire stem torque device is provided for tightening a valve stem of a tire mounted with one or more auxiliary tires on an axle of an automobile, without dismounting one or more of the auxiliary tires from the axle. The tire stem torque device includes a head member, an elongate member attached to the head member, and a handle attached to a distal end of the elongate member. The head member is configured of multiple sizes and defines a space configured to receive a valve stem of multiple sizes. The elongate member is configured of an adjustable length to create sufficient torque for the tightening of the valve stem of the tire.
