The present invention discloses an angle-adjustable crowbar that comprises a crowbar body and a crowbar head. The crowbar head includes a first hinge base and a second hinge base in a spaced manner, and a head of the crowbar body is rotatably mounted between the first hinge base and the second hinge base through an angle adjustment mechanism. The angle adjustment mechanism comprises a limit shaft penetrating through the first hinge base, the crowbar body and the second hinge base, a first tooth portion, a polygonal limit portion and a second tooth portion are sequentially disposed on an outer wall of the limit shaft in an axial direction. The angle-adjustable crowbar overcomes the defects that the limit strength of existing crowbars is weak, the tooth portion is unlikely to be damaged, and the crowbar head cannot be replaced.

A pounding, prying, and screwing hand tool for setting a screw and creating a dimple therearound includes a hammerhead, which is attached to a first end of a handle. A screw bit is attached to, or is selectively attachable to, a second end of the handle so that the screw bit extends axially from the handle. The handle can be grasped in a hand of a user, positioning the user to set a respective screw into a sheet of drywall using the screw bit and to selectively impart a dimple into the sheet of drywall by pounding the screw using a rounded face of the hammerhead.

A door opening system includes a trailer that has a door and the door has a door handle. A tool is provided and the tool may be manipulated. The tool has a striking surface to strike an object when the tool is swung at the object. The tool has a gripper and the gripper engages the door handle thereby facilitating the door handle to be manipulated. The gripper has a functional width of at least thirty two mm. The tool has a first hook to engage a device thereby facilitating the device to be remotely manipulated. The tool has a tapered end to engage a ratchet thereby facilitating the tool to rotate the ratchet.

A safety hammer is provided that may be designed to prevent injuries caused by flying nails when users accidentally fail to strike nails on their heads. The present invention may provide for a wooden handle with finger grooves. The wooden handle may be reinforced with a steel rod to add strength and attach the handle to the tempered steel head. Close to the end used for striking nails, the present invention may provide for a pin configured to attach the metal shield to the end used for striking nails. The track in the shield may fit over the pin to ensure the pin is positioned correctly around the face of the present invention's hammer face. In some embodiments, the shield may be secured by magnets, which may be embedded around the present invention's hammer head. The present invention may also provide for a fulcrum point that may be oriented above the nail removal portion of the present invention.
