Description

Nail puller for wood

Technical Field

The invention relates to the technical field of tools, in particular to a nail puller for wood.

Background

In engineering, woodworking and construction, nails refer to hard metal (usually steel) in the form of pointed tips, which are used for fixing wood and the like. Hammers drive nails into objects, and electric nail guns and gas nail guns have also been developed. The nail can stabilize the article by hooking it by its own deformation and by friction.

When extracting the nail from timber, the traditional nail puller of using at present, like stubborn rod, hand vice, hollow pincers, nail hammer etc. nail fall easily appearing at nail pulling-out in-process, the nail breaks off, the unable problem of extracting of nail such as nail overlength.

Disclosure of Invention

The invention aims to provide a nail puller for wood, which can solve the problems that nails are easy to fall off, the nails are broken off, the nails are too long and the like in the nail pulling process of the conventional nail puller used at present can not be pulled out when the nails are pulled out of the wood.

In order to achieve the purpose, the invention adopts the following technical scheme: the nail pulling hammer comprises a hammer head and a middle tongue plate, wherein the hammer head comprises a hollow hammer plate, a claw part is arranged on the left side of the hollow hammer plate, connecting plates are respectively arranged on the front side and the rear side of the upper part of the hollow hammer plate, hammer head connecting holes are formed in the connecting plates, the middle tongue plate is arranged inside the hollow hammer plate, a nail pulling gap is formed between the middle tongue plate and the hollow hammer plate, a tongue plate connecting hole is formed in the middle tongue plate, and the tongue plate connecting hole is connected with the hammer head connecting hole through a bolt.

Furthermore, the upper part of the middle tongue plate is fixedly connected with the handle.

Furthermore, the section of the middle tongue plate is a triangular component, the bottom surface of the middle tongue plate is flush with the bottom surface of the hollow hammer plate, and the bottom surface of the middle tongue plate is provided with an inclined plane with an inclined inner side.

Furthermore, the middle tongue plate is rotatably connected with the connecting plate.

The working principle of the invention patent is as follows: during the use, earlier with the nail perk of cavum portion on with timber, in the nail that will perk after that passes the nail of pulling out clearance between cavity hammer block and the middle hyoplastron, the bottom surface and the timber of cavity hammer block contact, rotate to cavum portion one side through the handle and make the nail extract in can following timber, the relative rotation of middle hyoplastron and cavity hammer block can be convenient for the inserting and pulling out of nail.

After the technical scheme is adopted, the invention has the beneficial effects that: its simple structure, reasonable in design combines fixed principle through the face, takes the face nail face to combine when pressing from both sides tight nail, or the mode that the line nail face combines, and the nail turns round or breaks the phenomenon and reduces more than ninety percent, under the nail overlength condition, can do not shift and pull out the nail repeatedly, need not fill up the lumber skid, pulls out nail work load significantly reduced, pulls out nail efficiency and promotes greatly, also improves greatly to timber protection.

Drawings

In order to more clearly illustrate the embodiments of the patent of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the patent of the present invention, and other drawings can be obtained by those skilled in the art without inventive exercise.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a front view of the hammer head of the present invention;

FIG. 3 is a top view corresponding to FIG. 2;

fig. 4 is a schematic structural view of the middle tongue plate in the patent of the invention.

Description of reference numerals: the nail pulling device comprises a hammer 1, a middle tongue plate 2, a nail pulling gap 3, a handle 4, a hollow hammer plate 11, a claw part 12, a connecting plate 13, a hammer connecting hole 14 and a tongue plate connecting hole 21.

Detailed Description

Referring to fig. 1 to 4, the technical solution adopted by the present embodiment is: the hammer comprises a hammer head 1 and a middle tongue plate 2, wherein the hammer head 1 comprises a hollow hammer plate 11, the hollow hammer plate 11 is of a hollow cubic structure, a claw part 12 is arranged on the left side of the hollow hammer plate 11, the claw part 12 and the hollow hammer plate 11 are integrally formed, connecting plates 13 are respectively welded on the front side and the rear side of the upper part of the hollow hammer plate 11, hammer head connecting holes 14 are formed in the connecting plates 13, the middle tongue plate 2 is arranged inside the hollow hammer plate 11, a nail pulling gap 3 is formed between the middle tongue plate 2 and the hollow hammer plate 11, a tongue plate connecting hole 21 is formed in the middle tongue plate 2, internal threads are arranged in the tongue plate connecting hole 21, the tongue plate connecting hole 21 is connected with the hammer head connecting holes 14 through bolts, the bolts are in clearance fit with the hammer head connecting holes 14, the bolts penetrate through the hammer head connecting holes 14 and are in threaded, the nail can be conveniently inserted and pulled out.

The upper portion of middle hyoplastron 2 and handle 4 fixed connection, handle 4 welds on middle hyoplastron 2, and through handle 4 can be more laborsaving at the in-process of pulling out the nail, improve the efficiency of work.

The section of the middle tongue plate 2 is a triangular component, the bottom surface of the middle tongue plate 2 is flush with the bottom surface of the hollow hammer plate 11, the bottom surface of the middle tongue plate 2 is provided with an inclined surface inclined inwards, and the inclined surface is convenient to rotate in a matching manner with the end surface of wood in the nail pulling process, so that the wood cannot be damaged.

During the specific use, earlier with nail perk on the timber of goat's horn portion 12, the nail that will perk passes in the nail pulling clearance 3 between cavity hammer block 11 and the middle hyoplastron 2 after that, the bottom surface of cavity hammer block 11 contacts with timber, rotate to goat's horn portion 12 one side through handle 4 and make the nail pull out in can following timber, the relative rotation of middle hyoplastron 2 and cavity hammer block 11 can be convenient for inserting and pulling out of nail, at the in-process of pulling out the nail, the nail takes the face nail face to combine with cavity hammer block 11 and middle hyoplastron 2, or the mode that the line nail face combines, the nail falls to turn round or breaks the phenomenon and reduces ninety above ninety percent, under the nail overlength condition, can pull out the nail repeatedly without the transposition, do not need to fill up the lumber, the work load of pulling out the nail significantly reduces, the nail pulling efficiency promotes greatly, also improve the timber protection greatly.

The above description is only for the purpose of illustrating the patented technical solution and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the patented technical solution should be covered by the claims of the present invention without departing from the spirit and scope of the patented technical solution.
