Abstract
The utility model discloses a saw bit fixture of electric circular saw, including inner flange, outward flange, the inner flange passes through the output shaft of hole fixed connection electric circular saw, the output shaft matched with hole with the electric circular saw is seted up to the outward flange, the inner flange sets up in one side of saw bit, and the outward flange sets up in the opposite side of saw bit, the output shaft of electric circular saw passes the hole of inner flange and stretches out from the hole of outward flange, compresses tightly inner flange and outward flange on the saw bit through the screw, the one end of inner flange is formed with first boss, and the other end of inner flange is formed with the second boss, one of them boss of inner flange stretches into the centre bore of saw bit. The utility model discloses can realize that different saw bits exchanges and guarantees effectively to press from both sides tightly to improve the commonality of electric circular saw, reduced the specification kind of electric circular saw.
Description
Technical field
The utility model relates to a kind of electric circular saw, is specifically related to the saw blade clamping mechanism of a kind of electric circular saw.
Background technology
The saw blade clamping mechanism of existing electric circular saw is as it is shown in figure 1, include inner flange 2, outward flange 4, and inner flange 2 passes through endoporus
The fixing output shaft 1 connecting electric circular saw, one end of inner flange 2 is formed with boss, and boss matches with the centre bore of saw blade 3；
Outward flange 4 offers the endoporus that the output shaft 1 with electric circular saw matches；
Inner flange 2 is arranged at the side of saw blade 3, and the boss of inner flange 2 stretches into the centre bore of saw blade 3；Outward flange 4 is arranged at
The opposite side of saw blade 3；The output shaft 1 of electric circular saw passes the endoporus of inner flange 2 and stretches out from the endoporus of outward flange 4, passes through spiral shell
Inner flange 2 and outward flange 4 are pressed on saw blade 3 by nail 5, it is achieved the clamping to saw blade 3.
The saw blade clamping mechanism of this structure, the boss diameter of inner flange 2 matches with the centre bore of saw blade 3, to ensure saw blade
3 is concentric with output shaft 1, it is to avoid rotation imbalance during work.But, the diameter of its centre bore of saw blade of different size is different,
When user needs the saw blade changing different size, it is impossible to directly utilize this clamping device.
Utility model content
Technical problem to be solved in the utility model is to provide the saw blade clamping mechanism of a kind of electric circular saw, and it can clamp different rule
The saw blade of lattice.
For solving above-mentioned technical problem, the technical solution of the saw blade clamping mechanism of the utility model electric circular saw is:
Including inner flange 2-1, outward flange 4, inner flange 2-1 fixes the output shaft 1 connecting electric circular saw by endoporus；Outward flange 4
Offer the endoporus that the output shaft 1 with electric circular saw matches；Inner flange 2 is arranged at the side of saw blade 3, and outward flange 4 is arranged at
The opposite side of saw blade 3；The output shaft 1 of electric circular saw passes the endoporus of inner flange 2 and stretches out from the endoporus of outward flange 4, passes through spiral shell
Inner flange 2 and outward flange 4 are pressed on saw blade 3 by nail 5；One end of described inner flange 2-1 is formed with the first boss 2-1-1,
The other end of inner flange 2-1 is formed with the second boss 2-1-2；One of them boss of inner flange 2 stretches into the centre bore of saw blade 3.
The external diameter of described first boss 2-1-1 and the second boss 2-1-2 is different.
The external diameter of described first boss 2-1-1 and the second boss 2-1-2 is respectively for the centre bore of the saw blade 3 of two specifications.
What the utility model can reach has the technical effect that
The utility model is capable of different saw blades and exchanges and ensure effectively clamping, thus improves the versatility of electric circular saw, subtracts
Lack the specification kind of electric circular saw.
Accompanying drawing explanation
With detailed description of the invention, the utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the schematic diagram of the saw blade clamping mechanism of prior art electric circular saw；
Fig. 2 is the schematic diagram of the saw blade clamping mechanism of the utility model electric circular saw；
Fig. 3 is the schematic diagram of inner flange of the present utility model.
Description of reference numerals in figure:
1 is the output shaft of electric circular saw, 2,2-1 be inner flange,
3 is saw blade, and 4 is outward flange,
2-1-1 is the first boss, and 2-1-2 is the second boss,
5 is screw.
Detailed description of the invention
As in figure 2 it is shown, the saw blade clamping mechanism of the utility model electric circular saw, including inner flange 2-1, outward flange 4, inner flange
2-1 fixes the output shaft 1 connecting electric circular saw by endoporus；Inner flange 2 is arranged at the side of saw blade 3, and outward flange 4 is arranged at saw
The opposite side of sheet 3；The output shaft 1 of electric circular saw passes the endoporus of inner flange 2 and stretches out from the endoporus of outward flange 4, passes through screw
Inner flange 2 and outward flange 4 are pressed on saw blade 3 by 5, it is achieved the clamping to saw blade 3；
As it is shown on figure 3, one end of inner flange 2-1 is formed with the first boss 2-1-1, the other end of inner flange 2-1 is formed with
Two boss 2-1-2, the external diameter of the first boss 2-1-1 and the second boss 2-1-2 is different, the first boss 2-1-1 and the second boss
The external diameter of 2-1-2 is respectively for the centre bore of the saw blade 3 of two specifications；Outward flange 4 offers output shaft 1 phase with electric circular saw
The endoporus coordinated；
One of them boss (such as the first boss 2-1-1) of inner flange 2 stretches into the centre bore of saw blade 3.
When needing the specification changing saw blade 3, overturn inner flange 2-1, make another boss (such as the second boss 2-1-2) of inner flange 2
Stretch into the centre bore of another saw blade 3, different saw blades can be realized and exchange and ensure effectively clamping, thus improve electric circular saw
Versatility, decreases the specification kind of electric circular saw.
