The present invention primarily discloses a hand tool, especially a hand tool having a fast-turning structure.

Generally, existing T-type wrenches or socket wrenches and even hand tools such as screwdrivers use a rod, the user holds one end and twists, and the other end is connected to a screw or a nut to wait for driving. The member can rotate the screw or the nut while the user twists the hand tool, thereby achieving the effect of screwing or unscrewing, and the user can hold the hand tool stably while rotating along the rotating shaft. Between the two ends of the tool, so that the hand tool does not yaw during the rotation process, so that the operation can be carried out smoothly.

However, when the user directly holds the hand tool with his hand, it will cause the hand tool to directly rub against the hand when rotating, which will make the hand tool rotate smoothly, and the hand tool and the hand directly rub the user easily. The hand is injured, especially when the user uses a pneumatic tool to drive the hand tool. For this reason, a hand tool equipped with a grip sleeve has been developed, and the grip sleeve can rotate relative to the above-mentioned rod, and the user does not need to put the hand Holding the rod directly, you can avoid injury to the user's hand.
