Multifunctional hammer

Technical field

The utility model relates to a kind of multi-functional hammer head structure of hammer.

Background technology

In numerous instruments, can beat one by one nail with hammer, complete the operation that a plurality of workpiece are combined as a whole.This workpiece typically refers to nonmetallic materials, for example wooden unit; Certainly, this workpiece can be also metal material, for example sheet iron.

Fig. 4 draws one of hammer 10 of market circulation, connects a tup 20 at a handle 12, and tup 20 1 ends are anvils 22, another end is absorbed in a V-type groove 26, it is shorter that thereby fork is a length of two pawl 24, two pawls 24, and the paragraph that long pawl 24 exceeds short pawl 24 is considered as a cutter section of hitting 28.

In Fig. 5, tup 20 peripheries are considered as the back with the position of connection handle 12, and the position above drawing is defined as the top.Whole tup 20 top surfaces are comprised of the flat anvil end face 32 linking one cutter section of hitting end faces 30 and a pawl end face 42.The cutter section of hitting end face 30 and pawl end face 42 are all protruding curved surfaces, and both curvature or radius of curvature are in full accord.

The purposes of this hammer 10 is quite a lot of, for example tup 20 with 22 pairs of nails of anvil knock, two pawls 24 coordinate 26 pairs of nails of V-type grooves to carry out to pull out operation, or utilize the cutter section of hitting 28 to thrust inside object etc.

But the independent easy deflection of the stressed rotation of the cutter section of hitting 28 is unfavorable for that nail pulls out, and is towards anvil 22 beats on the contrary, just can be in the puzzlement that causes during nail pulling in use.Yet when wait pulling out nail when the V-type groove 26, two pawls 24 are come the ailhead below, want but to be hampered by smooth anvil end face 32 along pawl end face 42 curvature beats, must apply larger strength to handle 12, could be take anvil 22 edges lever up nail as fulcrum.

Secondly, the U.S. the 4th, 290, No. 583 Patent Case discloses a kind of nail pulling formula tups, and a wedge-like extending part is installed in the middle part, and the extending part summit exceeds the tup top surface, can reduce nail-removing resistance, relatively promotes the beat amplitude that two pawls lever up nail.It's a pity, two pawls are equal in length, there is no the design of the cutter section of hitting, and are unfavorable for that tup carries out object and cut a hole and wear action.

In addition, the U.S. the 5th, 027, No. 677 Patent Case discloses a kind of spade formula tup, forms a protrusion part at the tup top surface, and the protrusion part height surpasses pawl end face and anvil end face, still is unfavorable for the carrying out of nail pulling operation.Because this tup is the monodactyle moulding, can thrust as object being carried out as spade or pick, digging operation, can't complete on the contrary the effect of clamping nail.

Therefore, how to improve two not isometric hammehead structures of pawl, just become the problem that the utility model needs to be resolved hurrily.

Summary of the invention

In view of this, the problem of the design people's further investigated prior art relies on and is engaged in the experience of research and development and the manufacturing of related industry for many years, actively seeks solution, and develop goes out a kind of new hammer finally, commonly uses the problem of thing with improvement.

One of the utility model purpose is: adopt the structure that highly surpasses the tup end face, improve the nail pulling functions of two not isometric formula tups of pawl.

Because of reaching of above-mentioned purpose, a kind of hammer of the present utility model is characterized in that, a tup, this tup comprise an anvil and two pawls, and one of two pawls have more one section cutter section of hitting, and a protrusion part is shaped between anvil and pawl; One handle, this handle and this tup link together.

This tup top surface comprises two pawl end faces and a protrusion part end face, and the curvature of this protrusion part end face is higher than each this pawl end face.

This pawl end face is protruding curved surface.

This protrusion part summit is between the tip and an axis that extends along this handle central party of this pawl.

This tup top surface comprises that also one connects the anvil end face of this protrusion part end face.

This anvil end face is concave curved surface, convex surface, plane or inclined-plane.

This tup top surface comprises two pawl end faces and a protrusion part end face, and the curvature of protrusion part end face is higher than each pawl end face.In other words, the radius of curvature of each pawl end face is greater than the protrusion part end face.

Because the protrusion part end face is protruding curved surface, so the pawl end face of linking protrusion part end face is take protruding curved surface as good.The protrusion part summit between the tip of pawl and an axis that extends along the handle center position, facilitate tup with the protrusion part summit as fulcrum, be the swing of certain angle towards anvil, thereby improve the nail pulling functions of two not isometric formula tups of pawl.

In addition, the tup top surface comprises that also one connects the anvil end face of protrusion part end face, and this anvil end face is selected from concave curved surface, convex surface, plane and inclined-plane and forms one of group.

The beneficial effect that the utility model reaches is: facilitate tup with the protrusion part summit as fulcrum, be the swing of certain angle toward anvil, thereby improve the nail pulling functions of two not isometric formula tups 20 of pawl.The required angle of tup nail pulling, more extensive more than the not isometric formula tup of early stage two pawls, levering up ailhead increases relatively away from the height of workpiece.

Below, based on purpose, structure and the feature of graphic detailed description related embodiment, believe technology, means and effect that the utility model adopts, when can by one deeply and concrete understanding.
