The movable shield is characterized in that a guide wheel is arranged at the end part of the movable shield. When the movable shield is operated, the guide wheel is adopted as a supporting point, the operations of digging and groove cutting are more convenient and reliable, and the safety performance is high.
Description
Technical field
The utility model relates to a kind of biplate saw, relates in particular to a kind of movable shield that is used for the biplate saw.
Background technology
The biplate saw is a kind of hand held cutting tool that on same axis, is equipped with two opposite saw blades of direction of rotation.Because two saw blade direction of rotation are opposite, the recoil strength when making cutting work reduces greatly, has improved the efficient of cutting and the security of use.Select different saw blades for use, the biplate saw can be used for the cutting of unlike materials such as timber, metal, marble, ceramic tile.
Because the special construction of biplate saw; It often is used in borehole (fluting or perforate in the middle of the sheet material) operation; In the past biplate saw all be operator's hand tool with saw blade slowly contact workpiece cut; The dynamics of depth of cut and use is leaned on operator's experience and qualification fully, and the hand tool shakiness is easy to generate that sawtooth bursts apart and unsafe factor such as instrument recoil strength increasing.Be the safety of operation, the biplate saw is provided with fixed blade guard and revolvable flexible blade guard, and flexible blade guard in the past only plays protection at work.
Summary of the invention
The utility model provides a kind of movable shield that is used for the biplate saw to deficiency of the prior art, during this movable shield operation, is the strong point with the directive wheel, makes borehole and to cut groove more convenient to operate and reliable, and safe.
In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of movable shield that is used for the biplate saw; Comprise gear housing, gear box cover, two saw blades, and the fixed blade guard and the flexible blade guard that are arranged on two saw blade sides; It is characterized in that the end of said flexible blade guard is provided with directive wheel.
In the technique scheme, the end of said flexible blade guard is provided with alignment pin, and said directive wheel is rotating to be sheathed on the alignment pin.
In the technique scheme; Also be provided with the movable guard lining between said flexible blade guard and the gear box cover, said movable guard lining is the cylinder of a hollow, and wherein the madial wall of an end is provided with boss; The lateral wall of the other end is provided with annular boss; The lateral wall of said gear box cover is provided with first annular groove, and said boss is fastened in first annular groove, and the wall of said annular boss leans on the madial wall of flexible blade guard.
In the technique scheme, the said sidewall that is provided with the movable guard lining is provided with breach, is arranged with limiting plate in the breach.
In the technique scheme, also comprise torsion spring, an end of said torsion spring is fixed on the flexible blade guard, and the other end is fixed on fixed blade guard.
Beneficial effect: the utility model compared with prior art has following beneficial effect: 1) the utility model when operation is the strong point with the directive wheel, makes borehole and to cut groove more convenient to operate and reliable, and safe.
2) the utility model because part is made handling ease, has therefore effectively been avoided axial float owing to be provided with the movable guard lining, has improved security greatly.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: see Fig. 1～Fig. 7: a kind of movable shield that is used for the biplate saw; Comprise gear housing 9, gear box cover 11, two saw blades 4, and the fixed blade guard 1 and flexible blade guard 3 that are arranged on two saw blade 4 sides; The end of said flexible blade guard 3 has an expansion section; Said expansion section is provided with alignment pin 7, and alignment pin 7 is arranged with directive wheel 5, and described directive wheel 5 can rotate with respect to alignment pin 7.
Also be provided with movable guard lining 15 between said flexible blade guard 3 and the gear box cover 11; Said movable guard lining 15 is the cylinder of a hollow; And the madial wall of said movable guard lining 15 1 ends is provided with boss 152, and the lateral wall of the other end is provided with annular boss 150.The lateral wall of said gear box cover 11 is provided with first annular groove 110, and said boss 152 is fastened in first annular groove 110, and a wall of said annular boss 150 leans on the madial wall of flexible blade guard 3.
The sidewall of said gear box cover 11 is provided with 2 second grooves 112 that extend vertically, and said second groove 112 is suitable with boss 152.
The said sidewall that is provided with movable guard lining 15 is provided with breach 154, is arranged with limiting plate 17 in the breach 154.
Also comprise a torsion spring 13, an end of said torsion spring 13 is fixed on the flexible blade guard 3, and the other end is fixed on fixed blade guard 1.
During installation, gear box cover 11 is installed on the gear-box, fastening with the gear-box screw, again fixed blade guard 1 is contained on the gear box cover 11, fastening with the fixed cover fixed head through the fixed head screw.Directive wheel 5 is contained in the flexible blade guard 3, is located with alignment pin 7.
During use, in the borehole operation, earlier flexible blade guard 3 is opened to the lower left of instrument, the both hands instrument of holding with a firm grip; Open switch; Instrument is transferred and is made directive wheel 5 contact workpieces (specifically see Fig. 4～Fig. 7), be that fulcrum lifts instrument (rotation) with directive wheel 5 then, make the contact workpiece cutting gradually of two saw blades 4; Thickness throw according to workpiece is worn to cutting fully, cuts forward or backward as directive wheel 5 with directive wheel 5 again.Because the strong point when directive wheel 5 has been arranged as operation, make borehole and to cut groove more convenient to operate and reliable, the security of operating simultaneously is raising greatly also.
In sum, the utility model is owing to be equipped with directive wheel 5, makes borehole and to cut groove more convenient to operate and reliable, and the security of operating simultaneously is raising greatly also.In addition, therefore the utility model has effectively avoided axial float because the movable guard lining 15 that is provided with is simple in structure, and the gear box cover annular groove 110 that is mated is easy to process, has improved security greatly.
