Description
Technical field
This utility model relates to the adjusting means of chain saw, particularly relates to the saw chain adjusting means of a kind of chain saw.
Background technology
Current chain saw mainly has two kinds, and a kind of is the gasoline chain saw with electromotor as power, and another kind is with motor
For the electric chain saw of power, these two kinds of chain saws are all that the saw chain by high-speed motion realizes cutting function.In use,
If saw chain crosses pine may jump out of guide plate, cause the injury to operator, and the saw chain of tension may due to saw chain and
Excessive friction between guide plate and cause high temperature fault, chain saw is caused damage.Therefore chain saw is before use it is generally required to saw
Chain is adjusted, and existing chain saw is typically all during regulation and is adjusted respectively by hold down gag and front-and-back adjusting device
The tensioning degree of segment saw chain and the degree of compression, waste time and energy during causing regulation, and therefore some producers start research and development by one
Secondary rotation regulates the structure reaching tensioning simultaneously with compressing purpose, but current this structure is required for mostly by numerous
Parts coordinate realize, relatively costly, it is impossible to carry out marketing.
Summary of the invention
This utility model for wasting time and energy during the regulation of saw chain present in prior art, relatively costly, cannot
Carry out the defects such as marketing, it is provided that the saw chain adjusting means of a kind of new chain saw.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:

Detailed description of the invention
This utility model is described in further detail by 1-5 and detailed description of the invention below in conjunction with the accompanying drawings, but they are not
To restriction of the present utility model:
Embodiment 1
As shown in Figures 1 to 5, the saw chain adjusting means of a kind of chain saw, lead including chain saw housing 1, compression knob 2, saw chain
Board component 3, described chain saw housing 1 is provided with screw 4, also includes pushing component 5, transmission component 7, least one set elasticity group
Part 8, described screw 4 passes saw chain guide plate assembly 3, pushing component 5, transmission component 7 and threadeds with compressing knob 2, institute
Compression knob 2 bottom array stated is provided with groove 15, described elastic parts 8 be positioned at transmission component 7 top and with compression
Groove 15 bottom knob 2 matches, and matches with pushing component 5 bottom described transmission component 7, described pushing component 5
Being arranged on saw chain guide plate assembly 3, described compression knob 2 drives transmission component 7 to rotate by elastic parts 8, described biography
Saw chain guide plate assembly 3 is driven to move forward and backward by pushing component 5 when dynamic assembly 7 rotates.
During use, user rotate forward compression knob 2 time, compress knob 2 rotate during will along screw 4 by
Gradually move down, and compress during knob 2 rotates forward and drive transmission component 7 also to rotate with by elastic parts 8, from
And drive pushing component 5 to move forward, promotion saw chain guide plate assembly 3 is moved forward during moving forward by pushing component 5,
So that saw chain gradually tensioning, when saw chain guide plate assembly 3 moves into place the complete tensioning of i.e. saw chain, saw chain guide plate assembly 3 will
Cannot continue to move along, so that pushing component 5 cannot continue to move along so that transmission component 7 also cannot continue to turn
Dynamic, if now continuing to rotatably compress knob 2, then compressing the groove 15 bottom knob 2 can oppress elastic parts 8, and bullet
Property assembly 8 because possessing certain elasticity, i.e. compressed producing certain deformation during hard pressed, so that bullet
Property assembly 8 and groove 15 between occur depart from and skidding so that compress knob 2 can continue to rotate and move down
Continue to compress to saw chain guide plate assembly 3, after compression knob 2 compresses and puts in place, also will be unable to be rotated further, now complete saw chain
Compression and tensioning operation.Otherwise, to saw chain is loosened, only need to reversely rotate compression knob 2, then compressing knob 2 will
Gradually move up and saw chain guide plate assembly 3 will gradually move inward, complete the loosening up to saw chain.By above structure,
Allowing user only need to rotatably compress knob during regulation saw chain, its simple in construction, cost is relatively low, and convenient during regulation
Fast, it is easy to marketing.

Receiving the containing cavity 16 of spring 12, hoodle 11, described hoodle 11 is crushed on compression knob 2 end under the elastic acting force of spring 12
In the groove 15 in portion.
When the most non-tensioning, hoodle 11, spring 12 play centre in the During regular rotation compressing knob 2 and connect
The effect connect so that compress knob 2 and drive transmission component 7 to rotate when rotated, and in the state of saw chain guide plate assembly 3 tensioning
Under, transmission component 7 also cannot be rotated further, and when this compression knob 2 continues to rotate forward, compressing the groove 15 bottom knob 2 will
Compressing hoodle 11 also forces spring 12 to compress, and when spring 12 is compressed to a certain degree, hoodle 11 will be disengaged from compressing knob 2 end
Groove 15 corresponding to portion, now compresses knob 2 and can continue to rotate, when compressing knob 2 and turning to certain position, compress rotation
Next groove 15 bottom button 2 agrees with corresponding hoodle 11 again, the most constantly repeats, it is ensured that at saw chain guide plate assembly 3
After tensioning compress knob 2 still can constantly rotate and saw chain guide plate assembly 3 is compressed, until compression action complete into
Only.
As preferably, being provided with flat thread 19 bottom described transmission component 7, described pushing component 5 top is arranged
The boss 20 coordinated with flat thread 19, described transmission component 7 is had to drive pushing component 5 by flat thread 19, boss 20
And then drive saw chain guide plate assembly 3 to move forward and backward.
As preferably, described flat thread 19 quantity is two, the quantity of the boss 20 at described pushing component 5 top
It it is three.
As preferably, described transmission component 7 includes regulating wheel 13, spiral wheel 14, bottom the described wheel 14 that spirals with push away
Dynamic assembly 5 matches, and described elastic parts 8 is positioned at the top of regulation wheel 13, and described wheel 14 top array of spiraling are provided with
Fixing groove 18, described regulation is taken turns 13 bottom array and is provided with fixing post 17, and described fixing post 17 inserts fixing groove 18 one by one
In.
As preferably, described compression knob 2 includes that button lid 10, knob mold insert 9, described groove 15 are arranged at button lid 10
Bottom, described knob mold insert 9 one end is connected with button lid 10, and knob mold insert 9 other end is threadeded with screw 4.
As preferably, also including end cap 6, described end cap 6 pushes away compressing between knob 2 and chain saw housing 1 and block
Dynamic assembly 5, transmission component 7.
In a word, the foregoing is only preferred embodiment of the present utility model, all scopes applied for a patent according to this utility model
Impartial change and the modification made, all should belong to covering scope of the present utility model.
