Abstract
The utility model belongs to handling instrument technology, is specifically related to a kind of spring steel spanner.Described spring steel spanner is made up of spring steel clamp holder, lever two parts, and wherein, spring steel clamp holder is arc metal plate, and for holding parts, its two ends are arranged in the holddown groove of lever, and are fixed by bolt-locking.Have in described holddown groove for the flexible cavity of spring steel clip handle, this cavity bottom extends the hand-held end of lever.The utility model spring steel spanner adopts the spring steel holding parts with radian, toughness, can fit very well, not easily injuring part surface with circular pieces surface.And stretch out by regulating spring steel clamp handle the dismounting demand that size adapts to different size part.In addition, after product orientation hole uses cap nut location, due to the tension that cap nut is at that time stubborn, cause the situation of free-hand very difficult dismounting, this spanner quick-detachment all can be used to get off.
Description
Technical field
The utility model belongs to handling instrument technology, is specifically related to a kind of spring steel spanner.
Background technology
In work, conventional spanner divides two kinds, and one is solid wrench, and one is adjustable wrench, and inflexible hand one or both ends are shaped with the opening of fixed dimension, in order to twist the screw bolt and nut of certain size.Adjustable wrench design feature is the flat pliers mouth that regular jaw makes with serration; Flat pliers mouth is made in moving jaw one end; The other end makes the recessed jaw with serration; Press worm screw downwards, moving jaw can take off rapidly, exchanges jaw position.
Conventional spanner to hexagon, rhombus, octagonal, quincunx etc. have the part of corner angle to have good installation, dismounting effect, but cylindrical component Multi Loading and Unloading Functions is bad, and easily causes damage to piece surface when tightening, in addition, conventional spanner restricted application, all limits by part specifications.
Utility model content
The purpose of this utility model is: propose one and can solve cylindrical component handling problem well, also can not injuring part surface, and stretches out by regulating spring steel clamp handle the spring steel spanner that size adapts to the dismounting demand of different size part.
The technical solution of the utility model is: a kind of spring steel spanner, and it is made up of spring steel clamp holder, lever two parts, and wherein, spring steel clamp holder is arc metal plate, and for holding parts, its two ends are arranged in the holddown groove of lever, and are fixed by bolt-locking.
Have in described holddown groove for the flexible cavity of spring steel clip handle, this cavity bottom extends the hand-held end of lever.
Arc metal plate width is not more than 10mm.
The utility model has the advantages that: the utility model spring steel spanner adopts the spring steel holding parts with radian, toughness, can fit very well with circular pieces surface, not easily injuring part surface.And stretch out by regulating spring steel clamp handle the dismounting demand that size adapts to different size part, use this spring steel spanner, can get rusty in some old frocks, or the bolt of surface oxidation, nut all can be disassembled fast.In addition, after product orientation hole uses cap nut location, due to the tension that cap nut is at that time stubborn, cause the situation of free-hand very difficult dismounting, this spanner quick-detachment all can be used to get off.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the utility model spring steel spanner,
Wherein, 1-spring steel clamp holder, 2-lever, 3-locking screw.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Refer to Fig. 1, it is the structural representation of the utility model spring steel spanner.Described spring steel spanner is made up of spring steel clamp holder, lever two parts, and wherein, spring steel clamp holder is arc metal plate, and for holding parts, its two ends are arranged in the holddown groove of lever, and are fixed by bolt-locking.
In addition, have in described holddown groove for the flexible cavity of spring steel clip handle, this cavity bottom extends the hand-held end of lever.Thus there is enough cavitys for regulating the length of arc metal plate, to be applicable to the dismounting of different size bolt.
In addition, arc metal plate width is not more than 10mm, to ensure grip force.
During real work, power, by lever of holding with a firm grip, is applied on lever by operator, makes it rotate, and reaches the object of expection dismounting.The angle of release of spring steel clamp holder can according to the different free adjustment of twisted part external diameter.The detailed process that it regulates is: first ridden over by spring steel clamp holder on part gabarit edge, after having judged part external diameter, elongate or shorten the length that spring steel exposes, after determining length, use holds out against screw and holds out against spring steel, after guaranteeing that spring steel can not slide in lever groove, starts to turn lever.
At the cap nut that part locating hole uses, firmly excessive during owing to locating at that time, when causing product undercarriage, operator is free-hand twists motionless, and cap nut is not torn open not get off, and uses conventional spanner can produce impression to nut external diameter again, use this spanner to be unscrewed fast.First regulating spring steel clamp handle extension elongation, makes it to fit tightly with cap nut (fit area is cap nut external diameter profile about 1/2), and firmly rotating lever can loosen cap nut.
Bolt in frock, the local corrosion of long-time placement screw thread place, uses conventional spanner to destruction bolt overlay coating, to use this spanner to be disassembled, determines can continue after power bolt does processing of rust removing to use.
