Abstract
The invention discloses a kind of safety lumbering fret saw, including casing and ring like steel wire saw blade, casing is " C " shape structure, the bottom of casing is provided with main wheel and motor, motor is provided with driven pulley, the middle part movement of casing, which is provided with, tightens up wheel by driving main wheel to rotate after the governor gear group conversion in casing at the top of casing, main wheel, driven pulley and tighten up wheel and propped up a ring like steel wire saw blade, emergency stop button is installed on casing.The advantage of the invention is that：The ring like steel wire saw blade structure that " C " shape casing and three-wheel are propped up, cleverly change the spacing of round saw blade, cutting saw blade wedging cut surface during lumbering only above, other parts are remained in outside cut surface, the phenomenon for avoiding cut surface extruding saw blade occurs, ensure Felling Efficiency, increase economic efficiency；Emergency stop button is installed, when emergency occurs, motor can be automatically stopped rotation, prevent personal injury on casing.
Description
Technical field
The present invention relates to power tools technology field, more particularly to a kind of safety lumbering fret saw.
Background technology
Hand-held tree-dozer brings great convenience for the lumbering operation of forest worker, with traditional hand saw phase
Than greatly improving operating efficiency.But there is also some drawbacks, such as saw blade chain to lead to for hand-held tree-dozer in the market
Often directly propped up by two wheels of driving wheel and driven pulley of certain distance, along with wheel has certain diameter in itself, this just makes
There is certain width between round saw blade.During lumbering, round two saw blades can be in successive wedging cut surface, trees
In run-off the straight before being completely severed, come and go saw blade and be easy to due to having the state of width formation one in front and one in back, cut surface
That root saw blade of extruding below, causes the appearance of Caton phenomenon, influences Felling Efficiency, even burn damage tree-dozer, cause
Economic loss.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of safety lumbering fret saw simple in construction, easy to use.
In order to solve the above technical problems, the technical scheme is that：A kind of safety lumbering fret saw, its innovative point exist
In：Including casing and ring like steel wire saw blade, the casing is " C " shape structure, and the bottom of the casing is provided with main wheel and motor,
The motor is rotated by driving main wheel after the governor gear group conversion in casing, and driven pulley is provided with the top of the casing,
The middle part movement of the casing, which is provided with, tightens up wheel, and emergency stop button is provided with the casing.
Further, the main wheel, driven pulley and tighten up wheel and propped up a ring like steel wire saw blade.
Further, casing bottom spiral is connected with a telescopic handlebar.
The advantage of the invention is that：
（1）The ring like steel wire saw blade structure that " C " shape casing and three-wheel are propped up, the spacing of round saw blade is cleverly changed, lumbered
When only cutting saw blade wedging cut surface above, other parts remain in outside cut surface, avoid cut surface extruding saw blade
Phenomenon occur, ensure Felling Efficiency, increase economic efficiency.
（2）Emergency stop button is installed, when emergency occurs, motor can be automatically stopped rotation, prevent on casing
Generation personal injury.
（3）Telescopic handlebar can realize the job requirements of certain altitude, broaden the scope of work, and improve practical valency
Value.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation of safety lumbering fret saw of the present invention.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
As shown in figure 1, a kind of safety lumbering fret saw, including casing 1 and ring like steel wire saw blade 3, casing 1 are " C " shape knot
Structure, the bottom of casing 1 are provided with main wheel 4 and motor, and driving main wheel 4 revolves after motor is changed by the governor gear group in casing 1
Turn, the top of casing 1 is provided with driven pulley 2, and the middle part movement of casing 1, which is provided with, tightens up wheel 5, main wheel 4, driven pulley 2 and tightens up
Wheel 5 has propped up a ring like steel wire saw blade 3, emergency stop button is provided with casing 1, the bottom spiral of casing 1 is connected with one
Telescopic handlebar 6.
Wheel 5 is tightened up in use, moving and locking, tenses garland saw chain 3, starts motor, is adjusted by governor gear group
Take a turn for the better speed, is cut using the garland saw chain 3 between main wheel 4 and driven pulley 2, when being in an emergency,
Press emergency stop button, you can body stops motor and rotated, and prevents personal injury.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
For art personnel it should be appreciated that the present invention is not limited to the above embodiments, described in above-described embodiment and specification is explanation
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
