Description
Technical field
The present invention relates to cutting tool technical fields, can voluntarily adjust the elastic current source of chain more particularly, to one kind
Saw.
Background technique
Common electric chain saw includes guide plate lid, guide plate and chain.Be equipped with motor in the guide plate lid, the rear end of the guide plate can before
That moves afterwards is set in the guide plate lid, and the rear end of the chain is connected with the motor power, and the front end of the chain is around this
The front end of guide plate.That is, chain rotation is able to drive after motor work, to carry out sawing to trees etc..
However, after used a period of time, chain will necessarily be deformed to elongated.At this time, it may be necessary to manual adjustment
The tensioning of the chain degree.Common regulative mode is: loosening the fixing screws of guide plate, manually pushes guide plate forward.Obviously, in this way
Regulative mode it is extremely inconvenient, and adjust frequency it is higher.
Summary of the invention
The object of the present invention is to provide one kind can voluntarily adjust the elastic electric chain saw of chain, it has and can voluntarily adjust
The tightness of chain, thus the characteristics of greatly extending the service life of chain.
The technical scheme adopted by the invention is that:
The elastic electric chain saw of chain, including guide plate lid, guide plate, motor and chain, the rear end of the guide plate can voluntarily be adjusted
What can be moved forward and backward is set in the guide plate lid, and the rear end of the chain is connected with the motor power, and the front end sleeve of the chain around
In the guide chain groove of the guide plate, the elastic electric chain saw of chain that can voluntarily adjust further includes at least 1 tension spring, tension spring front end
It hooks the guide plate covers, rear end hooks one and adjusts on sliding pushing block, adjusting sliding pushing block is fixed on the rear end of the guide plate, to make
The guide plate has the trend of anterior displacement.
The elastic electric chain saw of chain that can voluntarily adjust further includes covering embedded in the guide plate for compressing the guide plate
Supporting plate.
The supporting plate is prepared using aluminum alloy materials.
The elastic electric chain saw of chain that can voluntarily adjust further includes a push rod, which, which is furnished with, makes it have to Forward
The pressure spring of dynamic trend, and the front end of the push rod and adjusting sliding pushing block match.
The push rod is in " 7 " font to which the rear portion of the push rod has tool extractor, and the front of the push rod is articulated in the guide plate
Cover, meanwhile, the guide plate cover be equipped with and the tool extractor match assembling structure boss.
The compression spring sleeve is on the push rod.
The invention has the advantages that compared with the prior art:
The tightness of chain can be voluntarily adjusted, to greatly extend the service life of chain.Of the invention can be certainly
The tension spring that row adjusts the elastic electric chain saw of chain, which makes guide plate always, has the trend of forward movement, to use for a long time in chain
And it is elongated after, the guide plate after forward movement may insure that chain is still within suitable tensioning state, voluntarily without using person
It adjusts.Meanwhile after tension spring tension is used up, push rod can continue to give the trend of guide plate forward movement, it is ensured that chain can be after
It is continuous to be in tensioning state, further extend the service life of chain.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:

Specific embodiment
Embodiment, as shown in Figure 1: can voluntarily adjust the elastic electric chain saw of chain, including guide plate lid 40, guide plate 50, electricity
Machine (being not shown on figure) and chain (being not shown on figure).What the rear end of the guide plate 50 can be moved forward and backward is set to the guide plate lid 40
Interior, the rear end of the chain is connected with the motor power, and the front end of the chain is around in the guide chain groove of the guide plate 50.For example,
The rear end of the chain can around and be buckled on the gear on the power output shaft for being fixed on the motor, so that the motor can
It drives the chain to rotate, and is convenient for more after the chain capable of being made to be in tensioning state, move backward after the guide plate 50 forward movement
Change the chain.
Concretely:
It further includes at least 1 tension spring 10 that this, which can voluntarily adjust the elastic electric chain saw of chain, and 10 front end of tension spring is hooked leads at this
On plate lid 40, rear end hook and adjusted on sliding pushing block 51 one, adjusting sliding pushing block 51 is fixed on the rear end of the guide plate 50, thus
Make the guide plate 50 that there is the trend of anterior displacement.In order to ensure the balance of pulling force, tension spring 10 is preferably with symmetrically arranged 2.
In this way, the guide plate 50 can be moved forward voluntarily under the pulling force of tension spring 10 after using a period of time chain elongation, it is ensured that should
Chain is still within tensioning state, and the process is adjusted without using person.
It further includes on the guide plate lid 40 for compressing the guide plate that this, which can voluntarily adjust the elastic electric chain saw of chain,
Supporting plate 20, the supporting plate 20 are prepared preferably with aluminum alloy materials.In this way, not only making the electric chain saw more beautiful.
Further say:
In conjunction with shown in Fig. 2 to Fig. 4, it further includes a push rod 30, the push rod that this, which can voluntarily adjust the elastic electric chain saw of chain,
30 equipped with the pressure spring 31 for making it have forward movement trend, and the front end of the push rod 30 and adjusting sliding pushing block 51 match.This
In embodiment, 31 sets of the pressure spring on the push rod 30, so that the rear end of the pressure spring 31 is withstood on the guide plate lid 40, front end withstands on this
The trend moved forward on push rod 30 to make the push rod 30 have.In this way, the push rod 30 can also push forward the guide plate 50, from
And the tensioning of the chain degree is adjusted again.In other words, which plays the role of secondary collaboration, in aforementioned tension spring
Adjusting force is supplemented when 10 pulling force deficiency.
The push rod 30 is in " 7 " font to which the rear portion of the push rod 30 has tool extractor 32, and the front of the push rod 30 is articulated in
On the guide plate lid 40.That is, the push rod 30 can rotate, to make the tool extractor 32 or be attached to the surface of the guide plate lid 40 or hang down
Directly in the surface of the guide plate lid 40.Meanwhile the assembling structure boss 41 that the guide plate lid 40 is equipped with and the tool extractor 32 matches.That is,
When the tool extractor 32 is attached to the surface of the guide plate lid 40, which can be hooked on the assembling structure boss 41, make the push rod
30 front end will not withstand on the rear end of the guide plate 50；When surface of the tool extractor 32 perpendicular to the guide plate lid 40, the tool extractor 32 is not
Blocking by the assembling structure boss 41 again, the push rod 30 can withstand on the rear end of the guide plate 50 and give the guide plate 50 to
Preceding thrust.In other words, after the pulling force of aforementioned tension spring 10 is used up, user can star the thrust of the push rod 30, quite
It is pushed in producing second level to guide plate 50, greatly increases the stroke of the guide plate 50, so that the chain is had longer
Service life, until the elastic force of the pressure spring 31 is also used up, which needs replacing just now.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
