Description
Technical field
The present invention relates to a kind of cutter structure, especially a kind of dual-purpose saw blade.
Background technique
Saw blade generally comprises fuselage and blade, and blade is needed to be fixedly connected by corresponding collet with fuselage, is typically different
The tail portion common shape of the blade of purposes is different therefore also different with the connection type of corresponding collet, has and passes through positioning
The connection type that hole and detent fit are fixed also has the connection type for using and being fixedly clamped, at present the collet in a kind of saw blade
A kind of blade that connection type matches can only be installed, when needing replacing the cutter with different tail shapes in cutting operation
When piece, the corresponding saw blade of integral replacing is needed, it is more inconvenient to use and carry.
Summary of the invention
Two kinds can be installed on a collet technical problem to be solved by the invention is to provide one kind has different tails
The blade of cage structure and replacement and dual-purpose saw blade easy to carry.
The technical scheme of the invention to solve the technical problem is: a kind of dual-purpose saw blade, including fuselage, setting exist
Collet, the first blade and the second blade on the fuselage, the tail portion of first blade is provided with location hole, described
The width of second blade is less than the width of first blade, and the two sides of the tail portion of second blade are provided with limit convex
Block, the collet include tool apron and gland, and the tail end of the gland is rotatably connected on the tail end of the tool apron, described
The turnover driving mechanism with flexible restoring organ is provided between gland and the tool apron, the turnover driving mechanism is used
In the tool apron is opened and closed up with the gland overturning under external force, the flexible restoring organ is arranged described
Turnover driving mechanism and the tool apron between, when the flexible restoring organ is in reset state described in gland with
The tool apron mutually clamps, and the first mounting rack with the first mounting groove, first peace are provided on the gland
Tankage be used to accommodate first blade tail portion and the tool apron, the slot bottom of first mounting groove is provided with and institute
The positioning column for the location hole cooperation positioning stated, the bottom of the tool apron is provided with the tail portion for accommodating second blade
The second mounting groove, the inside two sides of second mounting groove are provided with recessed with the limit of the described spacing block set cooperation limit
Slot, the width of second mounting groove are less than the width of the tail portion of first blade.
The top of the tool apron is provided with the second mounting rack with third mounting groove, sets on second mounting rack
It is equipped with circular shaft bore, the turnover driving mechanism includes the toggle being fixedly connected and drive shaft, and the toggle is located at described
Third mounting groove in, the drive shaft turns are arranged on the circular shaft bore, all side surfaces of the drive shaft
Arc surface and gentle face including central angle more than or equal to 180 °, the shape of the arc surface and the circular shaft bore
To match, the flexible restoring organ is the torsional spring being arranged between the toggle and second mounting rack, described
Fixation hole of the minimum widith greater than the aperture of the circular shaft bore, the top shape of the fixation hole are provided on two mounting racks
At the matched positioning surface in gentle face with the drive shaft, the end of the drive shaft sequentially passes through the circular shaft bore
And the fixation hole, when the torsional spring is in reset state, the circular arc of the drive shaft faces upward apical grafting in described
Fixation hole positioning surface on and the gland mutually clamped with the tool apron, when the toggle turns under external force
Drive shaft described in when dynamic along the circular shaft bore hole wall slide downward until the drive shaft gentle face with it is described
The positioning surface of fixation hole fit.Toggle is stirred when needing replacing cutter, toggle drives drive shaft to turn in circular shaft bore
It moves and moves gradually downward, when the positioning surface in the gentle face of drive shaft and fixation hole fits, gland and tool apron are kept at this time
Blade can be taken out and be replaced by natural opening state；After being installed in place the first blade or the second blade, gradually unclamps and dial
Button makes drive shaft under the action of torsional spring toward back rotation and integrally moves up, until gland and knife when torsional spring is in reset state
Seat mutually clamps, and the first blade or the second blade are connected and fixed, and overall structure is simple and replacement cutter is convenient, to the company of cutter
Connect also relatively firm, increase safety in utilization.
The arc surface of the drive shaft is semicircle cambered surface, and the gentle face of the drive shaft is plane.Not only process compared with
For convenience, and the gentle face of drive shaft be plane, when the positioning surface of fixation hole is also matched plane, more allowing blade replacement compared with
It is laborsaving；Since the arc surface of drive shaft is semicircle cambered surface, drive shaft is always with the center of circle of circular shaft bore when toggle rotates
Centered on rotate, guarantee that gland and tool apron can mutually be opened to take out blade.
The toggle is provided with connecting hole, and the drive shaft is horizontally through the connecting hole, the toggle with
The drive shaft is fixedly connected by fixed pin, and the fixed pin, which runs through, is arranged in the toggle and the drive shaft
It is interior and vertical with the axial line of the drive shaft.Structure is simple, easy to process, guarantees that toggle and fixed pin rotate synchronously,
Middle drive shaft can also be used other fixed forms and be fixedly connected with toggle, such as interference fit, integrated molding.
The tail end of the tail end of the gland and the tool apron is rotatablely connected by rotation axis.The tail end of gland can also be adopted
It is connected with the tail end of other Conventional rotary connection types and tool apron.
Compared with the prior art, the advantages of the present invention are as follows when needing to take out blade, make to overturn driving machine by external force
Structure opens tool apron and gland overturning, is put into the first blade at this time or the second blade is installed, will when being put into the first blade
First blade is put into tool apron along the first mounting groove and covers location hole and positions on positioning column, makes to turn over by external force after being put in place
Rotation mechanism mutually closes up tool apron with gland, and finally when flexible restoring organ is in reset state, gland is mutually pressed from both sides with tool apron
Tightly, the width due to the width of the second mounting groove less than the tail portion of the first blade at this time, the structure on two sides of the second mounting groove
It is pressed on the tail portion of the first blade, is jointly connected and fixed the first blade with positioning column, location hole；When installing the second blade,
Second blade is inwardly put into along the second mounting groove and is caught in spacing block set in limiting groove, then turnover mechanism is made by external force
Tool apron is mutually closed up with gland, finally when flexible restoring organ is in reset state, gland is mutually clamped with tool apron, at this time
Second blade in being connected and fixed by positioning column press on the second blade；The dismounting of blade and replacement process are very convenient, realize
Two kinds of blades with different tail structures are installed as needed on a kind of saw blade, overall structure is simple, user
Just, stable connection can effectively reduce and carry space, in practical application mountable curve saw blade and reciprocal saw blade both
It is frequently necessary to replace the blade used in same operating environment, fuselage can be that Electric saw blade tool fuselage is also manual saw blade machine
Body.
