Rotated with output shaft 22.In the present embodiment, the power tool 100 is available for a variety of work pieces such as cutting timber, metals
Diagonal cutting saw.
Above-mentioned power tool 100, including special woodworking saw blade, saw aluminium saw blade and emery wheel saw blade are wooden to be respectively used to cutting
Matter, aluminum and metal work piece, therefore wooden, aluminum and metal work piece can be met respectively according to selection is actually needed
There is the model of minimum cost simultaneously.Need to use compared to conventional cutting tools and can process wooden, aluminum and metal simultaneously
The compound saw blade of work piece, the power tool 100 have while identical even more superior crudy is reached
Lower cost, so as to reduce the use cost of user, and extend the service life of cutting member 40.
Please continue to refer to Fig. 1 and Fig. 2, power tool 100 also includes the metal skirt 60 at least partly covering cutting member 40,
The metal skirt 60 has preferable mechanical performance, therefore even if cutting member compared to existing shield (such as nerd pack)
40 can produce more spark when cutting metal, will not also be melted by spark, so as to have longer service life, improve this
The security of power tool 100.
Specifically, metal skirt 60 includes metal and moves shield and metal determine shield, the dynamic shield of metal can opposing metallic protect surely
What cover rotated and changed cutting member 40 is covered area.When metal, which moves shield opposing metallic, to be determined shield and turn to certain position,
Cutting member 40 can be covered completely and cutting member 40 is housed in metal skirt 60 completely.In the present embodiment, woodworking saw blade with
It is carbon tungsten hard alloy segmental saw piece (Tungsten Carbide Tipped, TCT) to saw aluminium saw blade, has preferable machine
Tool performance and longer service life.
Specifically, woodworking saw blade includes carpenter's sawtooth body and carpenter's sawtooth around woodworking saw blade main body, carpenter's sawtooth
Tooth form is left and right tooth.More specifically, the rear flank of tooth of carpenter's sawtooth is obliquely installed with respect to carpenter's sawtooth body, and adjacent carpenter's sawtooth
The incline direction of preceding edged surface is mutually staggered on the contrary, has higher cutting speed and preferable cut quality.
Sawing aluminium saw blade includes saw aluminium saw body and the saw aluminium sawtooth around saw aluminium saw body edge, and the tooth form of saw aluminium sawtooth is flat for ladder
Tooth.More specifically, saw aluminium saw blade includes flat tooth and the stepped tooth being arranged alternately, the rear flank of tooth of flat tooth be with where saw aluminium saw body
The vertical plane of plane, the rear flank of tooth of stepped tooth is in isosceles trapezoid, so as to it is not easy to break and with preferably cutting the degree of accuracy.
Further, the quantity of carpenter's sawtooth of woodworking saw blade is less than the quantity of the saw aluminium sawtooth of saw aluminium saw blade, therefore saws
Aluminium saw blade has more preferable cutting ability to cut aluminum work piece, and the carpenter's saw number of teeth amount of woodworking saw blade is smaller, so as to
Make the appearance bits amount of between cog larger, be not easy to cause saw blade to generate heat, and the friction of cutting edge and timber can be reduced, improve the woodworking saw blade
Service life.
In the present embodiment, woodworking saw blade, saw aluminium saw blade are identical with the diameter of the emery wheel saw blade, so as to install
Used on same fuselage 20.When cutting different materials, it is only necessary to which saw blade needed for selection carries out replacing can be without changing
Fuselage 20.
Referring to Fig. 3, fuselage 20 includes fixation kit 24, fixation kit 24 is installed on output shaft 22, and fixation kit 24 is set
There is clamping space with clamping cutting member 40, cutting member 40 is installed on output shaft 22 and follow output shaft 22 to rotate and avoid cutting
Part 40 is deviate from rotation process.
Specifically, fixation kit 24 includes the first pressing plate 242, the second pressing plate 244 and fastener 246.First pressing plate 242 with
Second pressing plate 244 is sheathed on output shaft 22 and is arranged at intervals, defeated so as to which cutting member 40 be limited in be collectively forming clamping space
On shaft 22.The one end of fastener 246 is inserted in output shaft 22, and the other end is held in the first pressing plate 242 with by the axle of the first pressing plate 242
To output shaft 22 is fixed on, so as to which cutting member 40 is fixed on output shaft 22, output shaft 22 can drive cutting member when rotating
40 rotate to cut work piece.
More specifically, fastener 246 includes the connecting portion that support division is less than support division with diameter, connecting portion is provided with outer spiral shell
Line, output shaft 22 offer screwed hole, and connecting hole is connected to output shaft 22 by screwed hole, and support division is close to connecting portion side
End face is held in the first pressing plate 242 away from the side of the second pressing plate 244.In this way, when changing cutting member 40, fastener 246 is first backed out,
Then the first pressing plate 242 and cutting member 40 are removed and new cutting member 40 is installed, the first pressing plate 242 is finally reinstalled again and twists
Tightly firmware 246, so as to quickly and easily complete the replacing of cutting member 40.
Further, the one end of output shaft 22 is provided with the fixed pan extended along own axes direction, and the first pressing plate 242 is with consolidating
Allocate face cooperation to fix on direction is rotated about axis with relative output shaft 22, so as to rotate around the axis of output shaft 22.
Above-mentioned power tool 100, it can conveniently change woodworking saw blade, saw aluminium saw blade and abrasive cutoff saw according to being actually needed
Piece, due to the saw blade of the high workpiece that can be applied to processing unlike material simultaneously of price, therefore the power tool need not be used
100 have relatively low purchase and use cost, and can reach preferable cutting effect simultaneously, and extend the use of cutting member 40
In the life-span, it reduce further the use cost of the power tool 100.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
