Impact.
In the preferred scheme of this utility model, the height H2 of described tight bushing is more than the first limited step to leading
Distance H3 during plate assembling.
In the preferred scheme of this utility model, described clamp nut has protruding rib, described protruding rib
For applying forces to tight bushing, with fixing chain saw guide plate.Protruding rib can be also used for strengthening lifting surface area, prevents pressure
The most excessive, damage protective cover.
In the preferred scheme of this utility model, described protective cover is provided with tight bushing, on described tight bushing
It is provided with the axle-steel silk back-up ring for preventing clamp nut from coming off.Axle-steel silk back-up ring is possible to prevent clamp nut from protective cover
Come off.
In the preferred scheme of this utility model, the bottom thread terminated line of described clamp nut and projection rib
Bottom is positioned on straight line.
The beneficial effects of the utility model are: this utility model chain saw, it is possible to prevent from directly making when not installing protective cover
With chain saw, simple in construction, safe and reliable.

Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
Refer to Fig. 1, a kind of chain saw, including for chain saw guide plate 4, housing 1 and the protective cover 2 being arranged on housing,
The fastening bolt 3 that at least one is fixed on housing, described fastening bolt has the first limited step 6, described first spacing
The top of step 6 is screw thread, and described fastening bolt 3 is equipped with clamp nut 5, from the bottom thread of clamp nut 5 at the bottom of nut
Distance H1 in portion is less than distance H3 when the first limited step to guide plate 4 assembles.Under this kind of structure, if operator does not installs
Protective cover, uses clamp nut resting guide, owing to H1 is less than H3, when clamp nut screws, at the first limited step, just stops
Only advance, it is impossible to guide plate is fastened, it is to avoid operator starts chain saw in the case of unshielded cover.
The bottom thread of clamp nut 5 is less than the height H2 of tight bushing to distance H1 bottom nut.So fasten spiral shell
Female 5 can tightly push down protective cover 2, prevent clamp nut 5 bottom from propping up guide plate 4, cause protruding rib 8 cannot be compacted fastening lining
Set 9, it is to avoid the bottom of the clamp nut impact on fastening effect.
Distance H3 when the height H2 of tight bushing assembles more than the first limited step to guide plate.
Having protruding rib on clamp nut, described protruding rib is used for applying forces to tight bushing, with fixing chain
Saw guide.Protruding rib can be also used for strengthening lifting surface area, prevents pressure excessive, damages protective cover.
Protective cover is provided with tight bushing, and described tight bushing is provided with the axle-steel silk for preventing clamp nut from coming off
Back-up ring.Axle-steel silk back-up ring is possible to prevent clamp nut to come off from protective cover.
The bottom thread terminated line of described clamp nut and the bottom of projection rib are positioned on straight line.
Housing 1 tightens fastening fixing bolt 3 and defines guide plate installation pedestal, to facilitate protective cover 2 location and installation.Protective cover 2
It is that chain saw is relatively isolated with operator, it is to avoid operator starts in the case of not installing completely by mistake, reduces sprocket at full speed wound and hit
The probability of people.Being fixed on protective cover 2 by tight bushing 9, it is to allow fastening that clamp nut 5 adds protruding rib 8 design
Nut 5 empty set has rotation and up and down motion condition on tight bushing, and clamp nut 5 is limited in fastening by axle-steel silk back-up ring 10
Do not fall off on lining 9, axial displacement can be produced when clamp nut 5 is fastened on fastening bolt 3 on housing 1, and protective cover 2 is not
Dynamic, so can operationally make user pacify first with on the guide plate press-assembling surface precompressed guide plate on protective cover 2 when installing chain saw
Dress is convenient.Fastening bolt 3 is provided with the second limited step 7, and this position is higher than the relative altitude after chain saw 4 installation, in order to prevent
User uses the fastening of general nut to install chain saw 4 in the case of not having protective cover 2, fastening bolt 3 is additionally provided with first spacing
Step 6, what the first limited step 6 limited clamp nut 5 moves down distance.
It is different from prior art, this utility model chain saw, it is possible to prevent from directly using chain saw when not installing protective cover, knot
Structure is simple, safe and reliable.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description made, or be directly or indirectly used in other phase
The technical field closed, is the most in like manner included in scope of patent protection of the present utility model.
