Abstract
The present invention relates to a kind of die nut, the present invention is by way of changing original outer hexagonal spanner and being changed into lever force from moment of torsion force, characteristic using ratchet non-return and the structure that allows a variety of outer hexagonal spanners to be nested together by screw thread simultaneously, so that compared with prior art, the present invention can unscrew outer-hexagonal bolt in Quick fastening more in narrow space, when solving conventional insufficient space, it will be reapposed over to rotate again on outer-hexagonal bolt after outer hexagonal spanner rotation certain distance and tighten the problem of unscrewing, also the outer hexagonal spanner of several different models is gathered together simultaneously, convenient use personnel carry and used.
Description
Technical field
The present invention relates to a kind of common tool, more particularly, to a kind of die nut.
Background technology
Die nut is a kind of conventional hardware ＆ tools, when the equipment of hex bolts installation site is more
And during narrow space, die nut can not carry out circular motion, can only adjust less angle every time,
Die nut must be taken out again after adjustment every time, again insert one end of long handle section or short handle section
In regular hexagon groove, short handle section or long handle section are rotated, so repeatedly, until tightening or tearing open completely
Untill bolt.But this mode of operation operating time length, labor intensity is big, is very easy to make
Labourer's fatigue, it is difficult that hex bolts is adjusted to run into extreme narrow space.It is simultaneously existing
Be used for fasten hex bolts spanner be all independent part hexagonal prism, due to its individual it is smaller,
Model is more, and each model is operated just for a kind of bolt of specification, therefore actually should
In, so more inner hexagon spanners is not allowed not only easy to maintain, easily causes loss, and worker
It must could be completed to different bolts by frequently exchanging corresponding inner hexagon spanner in use
Operation.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided Novel hexagonal spanner, can be more
Quick fastening unscrews outer-hexagonal bolt in narrow space, when solving conventional insufficient space, outer six
It will be reapposed over to rotate again on outer-hexagonal bolt after the spanner rotation certain distance of angle and tighten what is unscrewed
Problem, while also the outer hexagonal spanner of several different models is gathered together, convenient use people
Member carries and used.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：It is new
Die nut, including force application mechanism and outer hexagonal spanner device, it is provided with described force application mechanism
Fixed cover, described force application mechanism include the rotating shaft being fixed in the fixed cover, described rotating shaft
On be provided with ratchet and effort handle, the spine being engaged with the ratchet is provided with described effort handle
Pawl, described fixed cover are provided with the fixed handle being engaged with the effort handle, described force
Spring is provided between handle and described fixed handle, first bevel gear, institute are provided with described ratchet
Circular shaft is provided with the internal hexagonal spanner device stated, is provided with the top of described circular shaft and is bored with the first
The second bevel gear that gear is engaged, described fixed cover are provided with the axle being engaged with the circular shaft
Hold, described outer hexagonal spanner device includes the outer hexagonal spanner of several different models, described
Outer hexagonal spanner includes circular columns and the through hole being arranged in circular columns, and described through hole includes hexagonal
Shape through hole section and the cylindrical hole section being arranged in hexagon through hole section, in the outer hexagonal spanner
In addition to most small size outer hexagonal spanner, remaining described outer hexagonal spanner cylindrical hole intersegmental part is set
There is a screw thread, in the outer hexagonal spanner in addition to the outer hexagonal spanner of maximum number, remaining described outer-hexagonal
Spanner circular columns surface is provided with screw thread, in the outer hexagonal spanner at the top of minimum outer hexagonal spanner
Fixed cover is provided with, connecting pole is provided with described fixed cover, described connecting pole reaches institute
The fixed cover stated is outer, and the one end of the connecting pole outside the fixed cover is provided with knob, Suo Yousuo
The outer hexagonal spanner stated is engaged lower press-type by described circular columns and described cylindrical hole section
Number size is sequentially coaxially threadedly coupled.
In this way, moment of torsion is utilized to bolt applying power to drive spiral shell compared in general die nut
Bolt is rotated, and the present invention is exerted a force using basic lever principle to die nut, to drive bolt to rotate.
Die nut is allowd to be changed into erectting the force of motion from the force mechanism of previous level rotary motion
Mode.In the narrower and small place in position in use, the present invention is not necessarily like in general die nut one
It will again take out after sample rotating part angle and jail will be rotated again, but can exert a force up and down always,
Until bolt is tightened or this unscrews.The present invention by the mutual motion between effort handle and fixed handle,
So as to drive the ratchet being arranged on effort handle to promote pawl wheel, at this moment it is fixedly installed on ratchet
First bevel gear will promote second bevel gear rotate, second bevel gear rotate when outer hexagonal spanner device
Begin to rotate.In rotation space than in the case of narrow, the present invention can be continuously to effort handle
And force, outer hexagonal spanner device can be placed on bolt always, during tightening and unscrewing
Outer hexagonal spanner device abjection bolt is not needed, rotary speed is greatly accelerated, reduces work
The working strength of person.
The beneficial effects of the invention are as follows：Outer six can be unscrewed in Quick fastening more in narrow space
Corner bolt, when solving conventional insufficient space, outer hexagonal spanner will be again after rotating certain distance
It is placed on to rotate again on outer-hexagonal bolt and tightens the problem of unscrewing, while also several different models
Outer hexagonal spanner gather together, convenient use personnel carry and use.
