AI Technical Summary

Benefits of technology

[0007]According to another aspect of the present invention, the mouth extends from the handle at substantially 0° or 180° relative to the handle so that the prying tool can conveniently be used for different purposes with less effort.

Problems solved by technology

The aforesaid two conventional designs can only be used to turn lumbers and to pull out nails.
Further, these two designs are not orthopedically engineered.
Because the head and the handle are aligned in line, the user must employ much effort when operating the tool to turn a lumber.

Embodiment Construction

[0023]Referring to FIGS. 1˜3, a multipurpose prying tool in accordance with the present invention is shown comprising a handle 1, a prying head 2 at one end of the handle 1, and a prying tip 3 at the other end of the handle 1.

[0024]The handle 1 is a long bar having an I-shaped cross section. Further, an anti-slip grip 11 may be bonded to the periphery of the handle 1 (see FIGS. 4 and 5).

[0025]The prying head 2 comprises a long jaw 211, a short jaw 212, and a mouth 21 defined between the longjaw 211 and the shortjaw 212. The mouth 21 extends from the handle 1 at substantially 0° or 180° relative to the handle 1. The long jaw 211 and the short jaw 212 each have parallel teeth 221 or 222 arranged on the inner side and facing the mouth 21. The long jaw 211 has one end, namely the fixed end, joined with the fixed end of the short jaw 212 to the handle 1, and the other end, namely the free end, provided with a V-notch 23 for pulling out nails. Further, the long jaw 211 has a face 24 at on...

Abstract

A multipurpose prying tool, which has a handle, a prying head, which is fixedly connected to one end of the handle and has two jaws of different lengths arranged in parallel and a mouth defined between the two jaws and extending with the handle in horizontal, and a prying tip made in the form of a claw and obliquely extended from the other end of the handle for pulling out nails.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to a hand tool and more particularly to a multipurpose prying tool, which is practical for holding and turning wooden plates, pulling out nails, and driving in nails.[0003](b) Description of the Prior Art[0004]Various lumber turning tools are known. U.S. Pat. No. 4,762,303 discloses a lever type tool, which comprises an elongated handle, and a head having two opposed and spaced apart claws projecting in generally the same direction at opposite sides of a space to closely receive a portion of a rectangular cross section of a lumber member. One of the claws at one side of the space is substantially shorter in length than the other of the claws at the opposite side of the space. U.S. Pat. No. 4,826,136 is substantially similar to U.S. Pat. No. 4,762,303 with the exception that the claws have first inner surfaces; one claw has an outward convex outer surface to engage a work surface, and a sec...
