Description

A kind of restricted clearance nut handling instrument
Technical field
The utility model is related to a kind of restricted clearance nut handling instrument, can be applied to equipment in life production and installs, examines With the handling that fastening nut is connected in groove restricted clearance during repairing.
Background technology
In daily life, the installing/dismounting of equipment and life appliance, it is often necessary to be attached tightly using bolt nut Gu, according to the difference of the specification requirement of installing/dismounting connecting bolt nut, and connection fastening position, choose different type difference rule The nut handling instrument of lattice, carries out installation and removal work.
At present, the instrument that the handling of fastening bolt nut are generally used is adjustable wrench or fork spanner.Under normal circumstances, The charge and discharge operations space for connecting fastening bolt nut is generally plane space or convex surface space, is entirely capable of using adjustable wrench or fork spanner Enough dismounting requirements for meeting connection fastening bolt nut.But during the installing/dismounting of equipment and life appliance, can run into needs The nut for fastening or dismantling is in groove restricted clearance, it is impossible to nut is entered using conventional instrument adjustable wrench or fork spanner Row fastening is dismantled, and a kind of fastening suitable for coupling nut in groove restricted clearance or dismounting are processed accordingly, it would be desirable to design Specific purpose tool.
The content of the invention
The purpose of this utility model is to provide one kind to meet connection fastening nut handling in groove or hole restricted clearance Instrument easy, easy to process, rational in infrastructure.
To reach above-mentioned purpose, technical solution adopted in the utility model is:
A kind of restricted clearance nut handling instrument, including nut fixture, torsion transmission lever, hand-held pole, nut fixture is with turning round Power transmission lever is welded, and torsion transmission lever is welded with hand-held pole, and nut fixture is cylinder, and cylindrical end face is provided with regular hexagon Groove, then cut away the adjacent both sides of regular hexagon groove along cylindrical axis direction.
The material of the handling instrument is stainless steel.
Having the beneficial effect that acquired by the utility model:
The utility model can meet spiral shell in the installing/dismounting process further groove or hole restricted clearance of equipment or life appliance Cap fasten or disassembling section, the tool processes, using, operation facilitate.
Brief description of the drawings
Fig. 1 is restricted clearance nut handling instrument front view;
Fig. 2 is restricted clearance nut handling instrument left view;
In figure:1st, nut fixture;2nd, torsion transmission lever;3rd, hand-held pole.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, restricted clearance nut handling instrument described in the utility model includes nut fixture 1, torsion biography Bar 2, hand-held pole 3 are passed, nut fixture 1 is welded with torsion transmission lever 2, and torsion transmission lever 2 is welded with hand-held pole 3, nut fixture 1 is Cylinder, cylindrical end face is provided with regular hexagon groove, then cuts the adjacent both sides of regular hexagon groove along cylindrical axis direction Fall.The material of handling instrument is stainless steel.
In use, the one end of nut fixture 1 is stretched into limited recess space, filled with the fluting position clamping of nut fixture 1 Nut is unloaded, tight hand-held pole 3 is held and requires selection power thrusts according to handling, firmly rotate hand-held pole 3, pass through torsion transmission lever 2 Transmit the force on nut fixture 1, implement the charge and discharge operations of nut.
