Abstract
The invention discloses a double-rack claw hammer comprising a hammer handle, a hammer head, an upper rack, a lower rack, a claw, a gear and a gear handle. The hammer handle is in a hollow structure, the hammer head is connected to one side of the bottom of the hammer handle, the upper rack is mounted inside the hammer handle adjacent to the position above the middle of the one side of the hammer head, the lower rack is mounted inside the hammer handle adjacent to the position below the middle of the one side of the hammer head, one toothless side of the lower rack is connected to the claw, the gear is mounted between the upper rack and the lower rack and is connected to the upper and lower racks, and the gear handle is connected to the gear. The double-rack claw hammer has the advantages that when a nail is long or the combination of the nail and an embedded article is firm, the double-rack claw hammer is capable of guaranteeing clawing the nail smoothly without damaging the embedded article.
Description
Technical field
The present invention relates to a kind of claw hammer, relate in particular to a kind of Double-rack type claw hammer.
Background technology
The function of claw hammer is pounded article except hammering into shape, its most important function is just nail nipping, because it has used lever principle cleverly, therefore become one of instrument indispensable in engineers and technicians work, but, due to nail have long have short, and the firm degree difference in the object being embedded into, therefore using when common claw hammer, being easy to produce claw hammer can not trip out nail completely, or in the time of nail nipping because firmly compared with large and damage the object being embedded into.
Summary of the invention
For present claw hammer limitation in the use, the invention provides a kind of convenient Double-rack type claw hammer that uses.
A kind of Double-rack type claw hammer, comprises leadman's handle, tup, upper rack, lower tooth bar, nail nipping, gear, gear handle; Described leadman's handle is hollow structure, described tup is connected with described leadman's handle bottom one side, it is inner near the described tup one above position of middle side part that described upper rack is arranged on described leadman's handle, described lower tooth bar is arranged on the inner close relative middle side part of described tup of described leadman's handle with upper/lower positions, an anodontia side of described lower tooth bar is connected with described nail nipping, described gear is arranged between described upper rack and described lower tooth bar, described gear is connected with described upper rack, described gear is connected with described lower tooth bar, and described gear handle is connected with described gear.
Above-mentioned Double-rack type claw hammer, wherein, described leadman's handle is that metal material is made.
Above-mentioned Double-rack type claw hammer, wherein, described leadman's handle arranges a hollow slots in described lower tooth bar one side.
Above-mentioned Double-rack type claw hammer, wherein, described gear handle is connected with described gear by the hollow slots on described leadman's handle.
Above-mentioned Double-rack type claw hammer, wherein, described tup and described nail nipping are that metal material is made.
Above-mentioned Double-rack type claw hammer, wherein, described gear, described upper rack and described lower tooth bar are that metal material is made.
The invention has the beneficial effects as follows: in or object that nail is being embedded into long when nail, when combination more firm, Double-rack type claw hammer can, in ensureing to complete smoothly nail nipping work, also not damage and be embedded into object.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of Double-rack type claw hammer of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
A kind of Double-rack type claw hammer of the present invention, comprises leadman's handle 1, tup 2, upper rack 3, lower tooth bar 4, nail nipping 5, gear 6, gear handle 7 as shown in Figure 1; Leadman's handle 1 is hollow structure, tup 2 is connected with leadman's handle 1 bottom one side, it is inner near the tup 2 one above positions of middle side part that upper rack 3 is arranged on leadman's handle 1, lower tooth bar 4 is arranged on the inner close relative middle side part of tup 2 of leadman's handle 1 with upper/lower positions, an anodontia side of lower tooth bar 4 is connected with nail nipping 5, and gear 6 is arranged between upper rack 3 and lower tooth bar 4, and gear 6 is connected with upper rack 3, gear 6 is connected with lower tooth bar 4, and gear handle 7 is connected with gear 6.
The operation principle of foregoing invention is: nail nipping 5 hung on nail, fixes Double-rack type claw hammer, and transmitting gear handle 7, gear 6 will drive lower tooth bar 4 to move straight up along with rotating, and then drive nail nipping 5 to move up nail is taken out.
Further, leadman's handle 1 is made for metal material, can firmly connect gear 6, upper rack 3 and lower tooth bar 4.
Further, leadman's handle 1 vertically arranges a hollow slots in lower tooth bar 4 one sides, and for lower tooth bar 4 is connected with nail nipping 5, and gear 6 is connected passage is provided with gear handle 7; For lower tooth bar 4 moves passage is provided along vertical direction.
Further, gear handle 7 is connected with gear 6 by the hollow slots on leadman's handle 1, simple in structure, and junction, in the inside of leadman's handle 1, has reduced the incidence of fault.
Further, tup and nail nipping are that metal material is made, and metal material is durable, can guarantee the normal use of tup 2 and nail nipping 5.
Further, gear 6, upper rack 3 and lower tooth bar 4 are made for metal material, and metal material is durable, not easy to wear.
The foregoing is only preferred embodiment of the present invention; not thereby limit embodiments of the present invention and protection domain; to those skilled in the art; the scheme that being equal to of should recognizing that all utilizations description of the present invention and diagramatic content done replaces and apparent variation obtains, all should be included in protection scope of the present invention.
