Detailed description of the invention

Below in conjunction with drawings and Examples, technical characterictic and the advantage with other above-mentioned to the utility model are described in more detail.

Refer to Fig. 1, illustrate the concrete structure of nail hammer 10 first embodiment.This nail hammer 10 comprises 12, lever 20 and conjunction.Wherein, 12 comprise the portion of knocking 14 and nail pulling portion 16, and nail pulling portion 16 extends and is designed to the pawl type of bifurcated toward another side from the portion of knocking 14, and it has roughly V-shaped breach 18, is applicable to pull out the occasion of nail.

This lever 20 is connected to 12, and entirety is approximately perpendicular to 12 and extend certain length.In the present embodiment, lever 20 is designed to be integrated with 12.At some embodiment, lever 20 separates with 12, the two use that combines.

This lever 20 comprises hole 22, gap 24 and linkage section 26, and linkage section 26 refers to that lever 20 is positioned at 22Pang region, hole, and in order to connect lever 20 and 12, itself and 24Bei hole, gap 22 separate and homonymy not.

Described hole 22 is formed at lever 20 near 12 position, the large and small variation in hole 22, precisely materials amount and the toughness of control connection section 26.

24Zi hole, this gap 22 is cutd open to lever 20 edges toward nail pulling portion 16 directions.Briefly, with cutting ways such as laser cutting, electric discharge (EDM) cutting or grinding water cuttves, from lever 20 edges to hole 22 peripheral wall surface, cut out required width and shape, make lever 20 and 12 local separating.

In addition, respectively there is one group of recess 28 the forward and backward side of lever 20.Every group is made up of two recesses 28, and these recesses 28 are formed at lever 20 and are positioned at 24 both sides, gap, and each recess 28 has the combined hole 21 that runs through lever 20.

In the present embodiment, this conjunction is made up of two flat boards 30, and every flat board 30 thickness and recess 28 degree of depth are roughly equal, cross gap 24 and insert each group of recess 28 the insides.This flat board 30 forms two holes: one for slotted hole 32, is circular hole 34, and the corresponding combined hole 21 of these hole 32,34 alignment, is passed by a securing member 36 respectively, makes dull and stereotyped 30 firmly on lever 20, as Fig. 2.

Therefore, dull and stereotyped 30 are hampered by the aforementioned securing member 36 of circular hole 34 that passes through, and must not leave arbitrarily lever 20.Aforementioned by the securing member 36 of slotted hole 32, it is long that its diameter is less than hole, allows the relative lever 20 of nail pulling portion 16 to swing, and the stretching degree in gap 24 produced to restriction simultaneously.

In figure, this securing member 36 is rivets.In certain embodiments, securing member 36 can be the combination of screw and nut.At some embodiment, securing member 36 can be screw, locks in the combined hole 21 that has internal screw thread.

During nail pulling, the slotted hole 32 of nail hammer 10 is favourable.As shown in Figure 3, a nail 40 is followed closely on supporting surface 44, as desktop.Nail hammer 10 touches supporting surface 44 with 12, catches nail 40 to expose the ailhead 42 of supporting surface 44 with nail pulling portion 16.Lever 20 is bestowed to an active force, and portion 14 is knocked in order just like seesaw equally swings certain amplitude toward supporting surface 44.Then, lever 20 is got back to original position toward nail pulling portion 16 directions, makes the portion of knocking 14 repeat identical swing, is pulled up by nail pulling portion 16 until nail 16 gos deep into the position of supporting surface 44.

During nail pulling, linkage section 26, just like the elastic reaction as cantilever is rich in certain buffering effect, pulls up nail 40 gradually with the mode of operation relaxing, than the strong loss percentage of pulling out nail 40 and more can alleviate supporting surface 44.

It should be noted that lever 20 kinetic energy are passed to flat board 30 via the securing member 36 in conjunction with circular hole, related slotted hole 32 small motion in the same way, thus touch the securing member 36 in slotted hole 32, drive nail pulling portion 16 to pull up nail 40.This moment, gap 24 amplitudes of opening are limited to slotted hole 32 length, stop 12 excessively to separate with lever 20, can also use the blink of relative securing member 36 micro-swingings of slotted hole 32 wall, relax nail pulling portion 16 and nail 40, nail 40 and supporting surface 44 conflicting of relevant power to each other, relatively slow down the fluctuation as concussion.

Linkage section 26 the knock operation that be of value to nail hammer 10 same with slotted hole 32.In Fig. 4, nail hammer 10 hits ailhead 42 with the portion of knocking 14, and nail 40 is hammered into supporting surface 44.The reaction force of nail 40, is passed to 12 by the portion of knocking 14, so that 12 near lever 20, bumps against each other even, makes gap 24 pitch dimension shrinkages.

This moment, linkage section 26 can slow down the vibrations of part, offsets the active force knocking each time, reduces the vibrations of hand, reduces tired.In addition, along with a 12 relative lever 20 swings, may allow securing member 36 clash into slotted hole 32 walls, share the partial action power of knocking, effectively same to reducing hand vibrations.

According to the above description, still can derive other embodiment.For example Fig. 5, performance nail hammer the second embodiment, the difference of itself and the first embodiment is: adopt different conjunction.

The conjunction of the present embodiment is a connection sheet roughly taking the shape of the letter U 50.This connection sheet 50 has the lateral plate 54 of convergence part 52 and two almost parallels, and three is designed to be integrated.Every lateral plate 51 has the slotted hole 32 and circular hole 34 that are same as the first embodiment.

As shown in Figure 6, the 3rd embodiment of nail hammer 10, its structure with the first embodiment roughly the same, difference be in: this hole 22 is formed at lever 20 middle parts, related dull and stereotyped 30 and linkage section 26 move position, still in hole 22 2 sides.

Above-described embodiment is only explanation the utility model, and non-is restriction the utility model.Various variations, amendment and application that those skilled in the art derive from above-described embodiment are all in category of the present utility model.
