Detailed description of the invention
Refer to Fig. 1, illustrate the structure of nail hammer 10 specific embodiment.This nail hammer 10 comprises one 12, lever 20 and a limiting mechanism 30.12 divide into one knocks portion 14 and a nail pulling portion 16.Nail pulling portion 16 extends and bifurcated from the portion of knocking 14, and has a roughly V-shaped breach 18, is useful in the occasion pulling out nail.
This lever 20 connector 12, entirety is approximately perpendicular to 12 and extends certain length.In the present embodiment, lever 20 is designed to be integrated with 12.In some embodiment, lever 20 separates with 12, the two use that combines.
This lever 20 comprises gap, hole 22, one 24 and a linkage section 26.Hole 22 is formed at the middle part of lever 20, the large and small change in hole 22, can precisely the use doses of control connection section 26 and toughness.With cutting ways such as laser cutting, electric discharge (EDM) cutting or grinding water cuttves, cut open to lever 20 edge from hole 22 peripheral wall surface towards nail pulling portion 16, cut out the gap 24 of definite shape, make lever 20 be divided into two parts, and be bound up by linkage section 26.Therefore, linkage section 26 and gap 24 separated by hole 22 and not with.
This limiting mechanism 30 comprises two accommodation section 32 and limited parts 40.With reference to figure 2, these accommodation sections 32 are grooves of symmetrical shape, and accommodation section 32 width near nail pulling portion 16 is greater than the width of another accommodation section 32, so that lever 20 has two wedges 34, and each wedge 34 is between accommodation section 32 and gap 24.In addition, each accommodation section 32 is absorbed in the certain degree of depth from lever 20 edge toward hole 22 according to angle, adjoins bottom accommodation section 32 with gap 24, and accommodation section 32 opening gap gap 24 is far away.So, two wedges 34 are close to the distance of accommodation section 32 opening part, are defined as a ultimate range 52.
Limited part 40 comprises dististyle 44 and two lateral plates 46 of main body 42, two symmetrical shape.This main body 42 is thin rectangular sheets, and its length has direct relation to described gap 24 amplitude of opening.
Each dististyle 44 is inwardly curved from main body 42 minor face, has an angle therebetween, makes dististyle 44 have active force needed for reset.Therefore, the free end of two dististyles 44 is separated by a spacing 50, is less than the ultimate range 52 of two wedges 34.When dististyle 44 inserts accommodation section 32, can main body 42 be driven along wedge 34 inclined-plane near lever 20 edge, contact wedge 34 top even closely, limited part 40 is not easily left.
It should be noted that wedge 34 top and lever 20 marginal existence one height fall 38, itself and limited part 40 (or main body 42) thickness are roughly equal, so that main body 42 appearance keeps flushing with lever 20 edge.
As shown in Figure 3, each lateral plate 46 is curved in the corresponding long limit of main body 42, its be approximately perpendicular to main body 42 and and come the same of two wedges 34, prevent limited part 40 from leaving lever 20 slidably.
Next, the service condition of nail hammer 10 is further described.As shown in Figure 4, a nail 62 is followed closely on a supporting surface 60, as desktop.Nail hammer 10 touches supporting surface 60 with 12, catches nail 62 to expose the ailhead 64 of supporting surface 60 with nail pulling portion 16.Bestow an active force to lever 20, order knocks portion 14 just like seesaw is the same swing certain amplitude towards supporting surface 60.Then, lever 20 gets back to original position toward direction, nail pulling portion 16, makes the portion of knocking 14 repeat identical swing, until the position that nail 62 gos deep into supporting surface 60 is pulled up by nail pulling portion 16.
During nail pulling, linkage section 26, just as cantilevered spring, has certain buffering effect, pulls up nail 62 gradually, pull out than strong the loss percentage that nail 62 more can alleviate supporting surface 60 with gentle mode of operation.
It should be noted that, narrow accommodation section 32 coordinates corresponding dististyle 44, lever 20 kinetic energy is passed to the main body 42 of limited part 40, another dististyle 44 related inside wide accommodation section 32 in the same way and small motion, thus touch the wall of corresponding wedge 34, drive nail pulling portion 16 to pull up nail 62.Limited part 40 this moment, two wedges 34 are stoped excessively to separate with the length of main body 42, and therefore limit the amplitude of opening in gap 24, the blink of dististyle 44 micro-swinging in wide accommodation section 32 can also be used, relax nail pulling portion 16 and nail 62, the conflicting of relevant power between nail 62 with supporting surface 60, relatively slow down the fluctuation as concussion.
Be of value to same with limited part 40 of this linkage section 26 knocks operation.As shown in Figure 5, nail hammer 10 hits ailhead 64 with the portion of knocking 14, and nail 62 is squeezed into supporting surface 60.The reaction force of nail 62, is passed to 12 of nail hammer 10 by the portion of knocking 14, thus two wedges 34 near and gap 24 is reduced, even allow two wedges 34 mutually impinge upon together.This moment, linkage section 26 can slow down vibration amplitude, offsets the partial action power of at every turn knocking, and reduces the vibrations of hand, reduces tired.In addition, this limited part 40 contacts wide accommodation section 32 wall with dististyle 44, shares the part active force that two wedges 34 bump against, effectively same to the vibrations of reduction hand.
According to said structure, other embodiment still can be derived.As shown in Figure 6, the second embodiment of nail hammer is roughly the same with the first embodiment, and difference is in: each lateral plate 46 toward tilted, and comes one and be formed at outside the inclined-plane 36 of wedge 34 side.So, lever 20 outline is more more smooth than the first embodiment.
As shown in Figure 7, the 3rd embodiment of nail hammer is roughly the same with the first embodiment, and difference is in the edge of: each lateral plate 46 roughly in trapezoidal, and two hypotenuses and the corresponding dististyle 44 of lateral plate 46 adjoin.
As shown in Figure 8,4th embodiment of nail hammer 10 is roughly the same with the first embodiment, and difference is in and is formed at lever 20 in: hole 22 near the position of 12, so that linkage section 26 is connected lever 20 and 12, three surrounds other in hole 22, and related limiting mechanism 30 is along with changing position in hole 22.
More than illustrate just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection scope of the present invention.
