Description

Movable claw hammer

Technical field

The invention belongs to the hardware ﹠ tools technical field, relate to claw hammer, particularly nail can crooked movable claw hammer during nail pulling.

Background technology

Claw hammer is the hardware ﹠ tools that people commonly use, and its structure comprises long piece shape hammer body, is arranged on the post piece shape tup of an end on the hammer body, the nail puller that is connected with the hammer body other end, the handle that is connected with the hammer body middle part; Nail puller is the piece of wedge shape towards the outside, and the middle part of wedge is provided with V-arrangement nail nipping notch; The function of existing hammer, the function that nail puller is arranged again, as fulcrum during nail nipping take tup one end, V-arrangement nail nipping notch clamping ailhead drives when pulling out on the nail bar, ailhead moves as circular path take fulcrum as the center of circle and makes the whole plank body that breaks away from of nail bar to finish nail nipping, in the process of nail nipping, the nail bar can be pulled into the arc bending unavoidably.

Adopt the claw hammer of such structure certainly can be used for hammering and pull out nail, but the nail of extracting is buckled, need when secondary utilizes old nail first its hammer to be beaten out directly, be not easy to the secondary utilization of nail, result of use is desirable not enough.

Summary of the invention

For overcoming the deficiencies in the prior art, nail can crooked movable claw hammer when the invention provides a kind of nail pulling.

The present invention reaches the technical scheme that above-mentioned technical purpose adopts to be: movable claw hammer comprises long piece shape hammer body, is arranged on the post piece shape tup of an end on the hammer body, the nail puller that is connected with the hammer body other end, the handle that is connected with the hammer body middle part; Nail puller is the piece of wedge shape towards the outside, and the middle part of wedge is provided with V-arrangement nail nipping notch; Nail puller integral body is the block of outer right angle " L " shape; The baseplane, right angle of the shape of the wedge outwardly transverse part of " L " flushes with the corresponding small end face of long piece shape hammer body; Be flexibly connected by the traveling priority guider between right angle face and hammer body one long face outside the vertical part of " L "; Handle one end and hammer body middle strand connect; Handle is flexibly connected by the wedge shape transverse part of link member with " L " near hammer body section place.

Described guider is that the corresponding long face of hammer body is provided with "T"-shaped guide rail, and the right angle face is provided with "T"-shaped guide groove outside the vertical part of " L ", and "T"-shaped guide rail is connected movingly with "T"-shaped guide groove.

It is that handle one end is provided with two pike pole shape fork frame linkings that the bundle at described handle one end and hammer body middle part connects, and two fork arm ends of fork frame linking connect by wire nail spare and hammer body middle part two pencil of planes.

The flexible connection of described handle and nail puller " L " transverse part is that two fork arm armrest handles, one end of fork frame linking is connected to double link by wire nail spare bundle, and the other end of double link and nail puller " L " transverse part two sides connect by wire nail spare bundle.

Described hammer body is provided with torsion spring near the two sides of tup side, and torsion spring one end is fixedly connected with hammer body, the other end with pitch frame linking two the fork arm face is pressured is connected; Two sides, hammer body middle part is provided with the cuboid limited block, and handle and hammer body long edge position are when plumbness, and the top end face of fork frame linking is connected by subsides with the side of limited block.

The invention has the beneficial effects as follows: because nail puller integral body is the block of outer right angle " L " shape; The baseplane, right angle of the shape of the wedge outwardly transverse part of " L " flushes with the corresponding small end face of long piece shape hammer body; Be flexibly connected by the traveling priority guider between right angle face and hammer body one long face outside the vertical part of " L "; Handle one end and hammer body middle strand connect; Handle is flexibly connected by the wedge shape transverse part of link member with " L " near hammer body section place.During nail nipping, the movement locus of ailhead is the straight path parallel with the traveling priority guider, and the movement locus of the nail bar that is connected with the ailhead one also is straight path, and the nail bar can be not crooked, need not hammer into shape when secondary utilizes old nail again and strike the nail bar, and result of use is better.
