Description
Technical field
The utility model is related to a kind of rotary felling saws.
Background technology
At present, felling saw needs to pull saw blade that could cut down trees back and forth, still mostly using saw blade form structure
Saw blade is pulled rather to expend strength, and inefficiency back and forth；For this purpose, someone is cut down using electric saw, but electric saw structure is answered
Miscellaneous, volume is larger, and once lacks fuel or electric power, can not directly use；And for individual, electric saw is nor one
A conventional outfit, therefore, there is an urgent need for a kind of felling tools simple in structure, easy to use and high operating efficiency.
Invention content
The purpose of this utility model is to overcome above-mentioned deficiency provides a kind of simple in structure, easy to use and operating efficiency
High rotary felling saw.
What the purpose of this utility model was realized in：
A kind of rotary felling saw, the rotary felling saw include two pieces curved rod, the madial wall of the curved rod
On be provided with sawtooth, the top of two pieces curved rod is hinged by articulated shaft, and the lower part of two curved rods is set along its arcwall face
The sliding groove of arcuate structure is equipped with, axis pin vertically passes through two sliding grooves, and the bottom of two pieces curved rod is respectively connected with handle, a spiral shell
Bolt is spun on swivel nut）It is interior, and bolt and swivel nut are connected to by spring on handle respectively.
Compared with prior art, the beneficial effects of the utility model are：
The utility model replaces original dragsaw form back and forth using rotation, substantial saved muscle power, and it is simple in structure, make
With conveniently.
Description of the drawings
Fig. 1 is a kind of structure diagram of rotary felling saw of the utility model.
Wherein：
Curved rod 1, axis pin 2, articulated shaft 3, bolt 4, swivel nut 5, spring 6；
Sawtooth 1.1, sliding groove 1.2, handle 1.3.
Specific embodiment
Referring to Fig. 1, the utility model is related to a kind of rotary felling saw, the rotary felling saw includes two pieces arc
Shape bar 1 is provided with sawtooth 1.1 on the madial wall of the curved rod 1, and the top of two pieces curved rod 1 is hinged by articulated shaft 3,
The lower part of two curved rods 1 is provided with the sliding groove 1.2 of arcuate structure along its arcwall face, and axis pin 2 vertically passes through two slips
Slot 1.2, the bottom of two pieces curved rod 1 are respectively connected with handle 1.3, and a bolt 4 is spun in swivel nut 5, and bolt 4 and swivel nut 5 divide
It is not connected on handle 1.3 by spring 6；
In use, pulling up axis pin 2, by trees obvolvent between two pieces curved rod 1, axis pin 2, adjusting bolt 4 are then plugged
With swivel nut 5 so that two pieces curved rod 1 is in the mating reaction lower slider of sliding groove 1.2 and axis pin 2 and so that the fitting of sawtooth 1.1 is perpendicular
Bar, then lumbering can be realized in rotating curved bar 1 centered on trees；
In addition：It should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
