Abstract
The invention discloses a rack-type claw hammer provided with an adjusting groove, and belongs to the technical field of daily used tools. The claw hammer comprises a hammer head, a hammer handle and a claw wing, wherein the tail end of the claw wing is provided with an extension block; a cavity is arranged on one side of the hammer handle; the extension block is located in the cavity; a gear bar is arranged on the hammer handle; and the gear bar is connected with the hammer handle by a rotating shaft. According to the rack-type claw hammer provided with the adjusting groove, the gear bar is arranged on the hammer handle, and the extension block is arranged on the claw wing, so that nails can be pulled up vertically, and the relatively strong nail pulling ability can be provided; labors are saved and operations are fast; in addition, relatively big nails are pulled up without placing an object at a bottom, so that the claw hammer is more convenient to use.
Description
Technical field
The present invention relates to the everyday tools technical field, particularly a kind of rack-and-pinion claw hammer that is provided with regulating tank.
Background technology
Claw hammer is a kind of everyday tools commonly used.Traditional claw hammer is commonly called as Curved Claw Hammer, is carpenter's main tool commonly used, is mainly used to strike at the nail, correct or nail is extracted, when needs nail when timber is extracted, first use goat's horn section (nail nipping wing claw) to fasten the head of a nail, the recycling lever principle trips out nail.If encounter nail when longer, just need to be at the top of claw hammer pad thing, nail is longer, and the thing of pad is just thicker, and this will be pretty troublesome, and also need with large claw hammer while encountering larger nail.While using traditional claw hammer to pull out a nail, not only require great effort, and the nail tripped out usually can be crooked, can not reuse, this can cause waste indirectly.When using traditional claw hammer to draw out a nail, also can usually cause the damage of wood surface simultaneously.
Summary of the invention
In order to solve, existing claw hammer is cumbersome in the nail nipping process, effort, and the nail tripped out is crooked, can not reusable problem, and the embodiment of the present invention provides a kind of rack-and-pinion claw hammer that is provided with regulating tank.Described technical scheme is as follows:
The embodiment of the present invention provides a kind of rack-and-pinion claw hammer that is provided with regulating tank, comprise tup, hammer handle and the nail nipping wing, described nail nipping wing tail end is provided with extension block, described hammer handle side is provided with a cavity, described extension block is positioned at described cavity, and described hammer handle is provided with gear stick, and described rotating shaft is passed through the center of circle of described gear and is connected with described gear.
Further technical scheme, described extension block is provided with teeth, described teeth are positioned at hammer handle one side, described gear stick is positioned at described hammer handle middle and lower part, described gear stick comprises gear and joystick, described gear is meshed with described teeth, and the center of circle of described gear is connected with described rotating shaft with described hammer handle.
Further technical scheme, described claw hammer also comprises regulating tank, and described regulating tank is positioned at described hammer handle bottom, and described rotating shaft is arranged in described regulating tank.
Further technical scheme, described regulating tank has one grade at least, and described gear moves up and down in regulating tank.
The beneficial effect that the technical scheme that the embodiment of the present invention provides is brought is: be provided with extension block by arranging on gear stick and the nail nipping wing on hammer handle, not only can vertically trip out nail, and stronger nail nipping ability, Quick labor-saving can be provided; Simultaneously rise need to be at base point pad thing than the spike period of the day from 11 p.m. to 1 a.m yet, convenient.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of claw hammer provided in the embodiment of the present invention 1;
Fig. 2 is a kind of claw hammer provided in the embodiment of the present invention 2.
In figure: 1 hammer handle, 2 joysticks, 3 gears, 4 tups, 5 cavitys, 6 extension blocks, the 7 nail nipping wings, 8 regulating tanks.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
As shown in Figure 1, the embodiment of the present invention provides a kind of claw hammer, comprise tup 4, hammer handle 1 and the nail nipping wing (claw) 7, nail nipping wing tail end is provided with extension block (tooth bar) 6, and hammer handle 1 side is provided with a cavity 5, and extension block 6 is positioned at cavity 5, described hammer handle 1 is provided with gear stick, and described gear stick is connected by rotating shaft with described hammer handle 1.Wherein, extension block is provided with teeth, and teeth are positioned at hammer handle 1 one sides, and gear stick is positioned at hammer handle 1 middle and lower part, and gear stick comprises gear 3 and joystick (gear handle) 2, and gear 3 is meshed with teeth, and rotating shaft is passed through the center of circle of gear and is connected with gear 3.
Brief description the present embodiment claw hammer course of work:
As shown in Figure 1, when claw hammer uses, first the V-arrangement recess of claw 7 parts is pushed to head of a nail below, take the claw hammer top as the strong point, and one holds hammer handle 1, holds gear handle 2, utilize lever principle to press under joystick (gear handle) 2 is oblique, make the nail nipping wing 7 move up, thereby pulling device vertically upward, nail is remained vertically and trip out.Claw can be fixed on the nail of different size in the V-arrangement recess, thereby nail is pulled out.When needing the nail iron nail, knock the afterbody of iron nail with tup 4 and just can nail.The embodiment of the present invention Shi Buxu pad thing that pulls out a nail is not crooked when nail trips out; Operating process, because lever transmits than being greater than 20:1, has reduced resistance arm, has increased the ratio of power arm and resistance arm, thereby has reduced power, provides stronger nail nipping ability, Quick labor-saving.With the technology of traditional claw hammer, compare faster, more convenient, more laborsaving.
This clearly demarcated embodiment has adopted the method for vertical nail nipping, can make the utilization of nail secondary, adopts the pinion and-rack kind of drive, and resistance arm is less, has increased the ratio of power arm and resistance arm, more Quick labor-saving; Simultaneously easily manufactured, cost is lower.
As shown in Figure 2, this clearly demarcated embodiment compares and also comprises regulating tank 8 with embodiment 1, and this regulating tank 8 is positioned at hammer handle 1 bottom, and rotating shaft is arranged in regulating tank.This regulating tank has one grade at least, is preferably four to five grades, and gear 3 can move up and down in regulating tank.Regulating tank can adjusting gear 3 heights, with the needs of the nail that adapts to different size.
This clearly demarcated embodiment has adopted the method for vertical nail nipping, can make the utilization of nail secondary, adopts the pinion and-rack kind of drive, and resistance arm is less, has increased the ratio of power arm and resistance arm, more Quick labor-saving; Simultaneously easily manufactured, cost is lower.In addition, due to regulating tank adjusting gear gear being set, also can conveniently trip out longer nail.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
