Abstract
The utility model provides a kind of electric shear blade mechanisms, is in two-sided circular arc obvolvent shape after the ledger-plate and cutting blade combination including the blade mechanisms being made of ledger-plate and cutting blade.It is in two-sided circular arc obvolvent shape after ledger-plate and the cutting blade combination of the utility model, during cutting blade effect ledger-plate is engaged with branch, the phenomenon that branch is fixed therein, is not in sliding branch by two-sided circular arc obvolvent shape；The ledger-plate tail end of the utility model is provided with outwardly projecting scratch resistant, extends the operating distance with cutting blade, so that in cutting blade mechanism, the phenomenon that being not in scraper.
Description
Technical field
The utility model relates to a kind of electric shear technology, especially a kind of electric shear blade mechanisms.
Background technique
Now with forestry and the development of agricultural, need to trim branch according to demand, the prior art is largely
Branch is trimmed by manual operation scissors, large labor intensity, the pruning efficiency is low, and safety is poor during trimming, therefore
Existing to occur many electric shears on the market, electric shear is typically provided with a cutting blade and a ledger-plate, cutting blade
Shear mechanism is combined into ledger-plate group, but existing cutting blade and the ledger-plate cutting blade and fixed under the action of screw rod transmission
In blade action, often generate hanging branch the phenomenon that, and cutting blade effect ledger-plate when be engaged with branch during, be easy to appear
Sliding branch.
Utility model content
In view of this, the main purpose of the utility model, which is that, provides a kind of electric shear blade mechanisms.
To solve the above-mentioned problems, the utility model provides a kind of electric shear blade mechanisms, including by ledger-plate
It is in two-sided circular arc obvolvent shape after the ledger-plate and cutting blade combination with the blade mechanisms of cutting blade composition.
Preferably, the ledger-plate tail end is provided with outwardly projecting scratch resistant.
Preferably, described scratch resistant is integrated setting with ledger-plate.
Preferably, it is respectively corresponded on the ledger-plate and cutting blade and is provided with fixation hole, pin will across the fixation hole
Ledger-plate and cutting blade are fixed by gear nut.
Preferably, one end of the gear nut and buckle is fixed, and the other end and ledger-plate of the buckle pass through screw
It is fixed.
Preferably, the side of the ledger-plate and the mutual obvolvent of cutting blade be respectively arranged with the ledger-plate circular arc that concaves and
Cutting blade circular arc.
Utility model has the beneficial effect that
1. being in two-sided circular arc obvolvent shape after ledger-plate and the cutting blade combination of the utility model, when cutting blade acts on ledger-plate
During being engaged with branch, the phenomenon that branch is fixed therein, is not in sliding branch by two-sided circular arc obvolvent shape；
2. the ledger-plate tail end of the utility model is provided with outwardly projecting scratch resistant, the effect with cutting blade is extended
Distance, so that in cutting blade mechanism, the phenomenon that being not in scraper.
Detailed description of the invention
The present invention is described in detail by the following detailed description and drawings for ease of explanation,.
Fig. 1 is the explosive structural schematic diagram of the utility model；
Fig. 2 is that the blade mechanisms of the utility model are applied to the implementation example figure of electric shear.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing and specific embodiment, in the signal of this utility model
Property embodiment and explanation be used to explain the utility model, but be not intended to limit the scope of the present invention.
Referring to figs. 1 to Fig. 2, the utility model provides a kind of electric shear blade mechanisms, including by ledger-plate 1 and moves
The blade mechanisms that blade 9 forms respectively correspond on the ledger-plate 1 and cutting blade 9 and are provided with fixation hole 5, and pin 10 passes through institute
State fixation hole 5 ledger-plate 1 and cutting blade 9 is fixed by gear nut 2.One end of the gear nut 2 and buckle 3 is fixed,
The other end and ledger-plate 1 of the buckle 3 are fixed by screw 4.
The side of the ledger-plate 1 and the mutual obvolvent of cutting blade 9 is respectively arranged with the ledger-plate circular arc 7 and moving knife to concave
Therefore piece circular arc 8 is in two-sided circular arc obvolvent shape after the ledger-plate 1 and the combination of cutting blade 8, when cutting blade 9 passes through screw rod transmission
During effect ledger-plate 1 is engaged with branch, branch is fixed therein by two-sided circular arc obvolvent shape, is not in showing for sliding branch
As.
1 tail end of ledger-plate is provided with outwardly projecting scratch resistant 6, and described scratch resistant 6 is integrated with ledger-plate 1 and sets
It sets.Described scratch resistant 6 extends ledger-plate 1 and prolongs during being engaged branch and acting ratcheting cut by cutting blade 8 with cutting blade 8
Long mutual blade contact operating distance, so that in 8 mechanism of cutting blade, the phenomenon that being not in scraper.
The basic principles and main features of the present invention and the advantages of the present invention, current row has been shown and described above
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention, the utility model
Claimed range is defined by the appending claims and its equivalent thereof.
