Further, it is flat that a connection is provided on the outside of the position that first bending part is connect with second bending part
Platform.
Further, the whirling spring body, the fixed detent portion and the extension section are made of stainless steel material.
The utility model has the following beneficial effects:
The fixed detent portion is fixed to the corresponding position of chain saw, by the stretching extension section, makes whirling spring body stress,
To start chain saw；The structure of starting whirling spring provided by the utility model for chain saw is simple, and processing is relatively easy to, and is passed through
The fixation detent portion of special construction and extension section realize fixed and start-up course, can effectively improve starting performance, extension makes
Use the service life.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structural schematic diagram of the starting whirling spring provided by the embodiment of the utility model for chain saw；
Fig. 2 is the side view of the starting whirling spring provided by the embodiment of the utility model for chain saw.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Such as Fig. 1 and Fig. 2, the utility model embodiment provides a kind of starting whirling spring for chain saw, including whirling spring body
1, fixed detent portion 2 and extension section 3；The whirling spring body 1 helically structure, is exactly spring body structure.The whirling spring body 1
Outboard end be connected to the fixed detent portion 2, the inner end of the whirling spring body 1 is connected to the extension section 3.
Such as Fig. 1 and Fig. 2, the fixed detent portion 2 is fixed in the corresponding fixed structure of chain saw.In this preferred embodiment
In, the fixed detent portion 2 includes the first bending part 21 and the second bending part 22, and first bending part 21 is by the whirling spring
The outboard end of body 1 extends outward, and second bending part 22 is reversely bent by the end of first bending part 21 to be prolonged
It stretches, the angle of first bending part 21 and second bending part 22 is acute angle, the length of second bending part 22
Less than the length of first bending part 21.Further, first bending part 21 is connect with second bending part 22
It is provided with a connecting platform on the outside of position, is through position, plays the role of buffering stress.Wherein, first bending part 21
It is straight plate part structure with second bending part 22, curved form will not be showed.
Such as Fig. 1 and Fig. 2, the fixed detent portion 2 can directly form a hook card division by above structure, can directly block
In the corresponding fixed structure of chain saw, it the situations such as will not fall off, compared to the existing fixed form by curved portion,
Processing technology and overall structure are simplified, fixation is also easier.
Such as Fig. 1 and Fig. 2, meanwhile, the extension section 3 is identical as the structure in the fixed detent portion 2.The extension section 3
