Abstract
The invention discloses an electric circular saw which comprises a shell, a motor arranged in the shell and a saw web in transmission connection with the motor. The motor is arranged above the saw web, an adjusting plate for adjusting the cutting depth of the saw web is arranged on the shell in a rotatable mode. When the adjusting plate rotates, the plane where the adjusting plate is located keeps perpendicular to the plane where the saw web is located and keeps parallel to the rotating axial line of the saw web. When the perpendicular distance between the rotating axial line of the saw web and the plane where the adjusting plate is located is the smallest, an included angle between the plane where the adjusting plate is located and the axial line of the motor is an acute angle alpha. The electric circular saw effectively reduces the overall length and width, improves the approachability and operability of the tool, and has a better ergonomic effect.
Description
Technical field
The present invention relates to a kind of electric circular saw, particularly relate to that a kind of volume is less, the better electric circular saw of accessibility.
Background technology
Electric circular saw of the prior art, the arrangement mode of its motor and saw blade two kinds: one is that electrical axis is parallel with saw blade nothing more than, and two is that electrical axis is vertical with saw blade.For the arrangement mode that electrical axis is parallel with saw blade, electric circular saw entirety can seem long, and such operability and accessibility are all poor; For the arrangement mode that electrical axis is vertical with saw blade, electric circular saw entirety can seem wider, and total is small and exquisite not, and the space taken is excessive.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of electric circular saw, comprise housing, be located at the motor in described housing, the saw blade be connected with described motor-driven, it is characterized in that: the top of described saw blade is located at by described motor, described housing is provided with the adjustable plate for regulating described saw blade depth of cut, described adjustable plate is connected with described housing into rotation by adjustable plate rotating shaft, the axial line of described adjustable plate rotating shaft and the axis parallel of described saw blade rotating shaft, described adjustable plate offers and extends and the saw blade groove that described saw blade can be made to pass freely through along described saw blade cut direction, when described adjustable plate rotates, described adjustable plate place plane keeps vertical with described saw blade place plane, the axial line keeping parallelism of described adjustable plate place plane and described saw blade rotating shaft, when vertical range between the axial line and described adjustable plate place plane of described saw blade rotating shaft is minimum, the angle between described adjustable plate place plane and the axial line of described machine shaft is sharp angle α.
Preferably, described sharp angle α is more than or equal to 30 degree.
Preferably, described adjustable plate place plane is positioned at below the axial line of described saw blade rotating shaft.
Preferably, the lower end of described housing is formed for being set in the guard shield outside described saw blade, and described guard shield partly hides described saw blade, and described adjustable plate is connected on described guard shield by adjustable plate axis of rotation.
Preferably, described housing is provided with first handle for gripping and second handle.
The axial line of motor and saw blade are that an angle is arranged by electric circular saw of the present invention, can reduce length and width so simultaneously, add the accessibility of instrument under the prerequisite not affecting tool performance, make ergonomics effect be improved significantly.

Detailed description of the invention
Below in conjunction with accompanying drawing being preferred embodiment described in detail to electric circular saw of the present invention.
See accompanying drawing 1-2, be defined as general work state when being placed according to shown position by electric circular saw, the definition about the orientation up and down of this electric circular saw is all as the criterion with the orientation up and down in accompanying drawing 1-2.Electric circular saw of the present invention comprises housing 1, and be located at the motor 2 in housing 1, motor 2 has rotating shaft 21; Saw blade 3 is generally circle, and its circle centre position is saw blade rotating shaft 31; Motor 2 to be positioned at above saw blade 3 and to be connected by transmission mechanism 11 with saw blade 3, and transmission mechanism 11 can be gear-box iso-variable velocity mechanism; The lower end of housing 1 forms guard shield 12; guard shield 12 can partly hide saw blade 3; play the effect of protection user; adjustable plate 4 is connected with on shroud 12 by adjustable plate rotating shaft 41; for regulating the depth of cut of saw blade 3, the axial line of wherein adjustable plate rotating shaft 41 and the axis parallel of saw blade rotating shaft 31.In the present embodiment, adjustable plate 4 offers one to extend along saw blade 3 cut direction and can allow the freely through saw blade groove of saw blade 3, adjustable plate 4 one end can be rotated relative to housing 1, and adjustable plate 4 place plane perpendicular to saw blade 3 place plane, is also parallel to the axial line of saw blade rotating shaft 31 all the time all the time.When adjustable plate 4 relative to housing 1 away from when rotating, saw blade 3 diminishes from saw blade Cao Nei exposed division branch, and such depth of cut will reduce; When adjustable plate 4 relative to housing 1 draw close rotate time, saw blade 3 from saw blade groove exposed division branch increase, such depth of cut will increase.Simultaneously, when adjustable plate 4 rotates, vertical range between adjustable plate 4 place plane and the axial line of saw blade rotating shaft 31 also can constantly change, when this is apart from time minimum, the exposed portion of corresponding saw blade 3 is also maximum, corresponding maximum depth of cut, accompanying drawing 1 depicts state when electric circular saw is in maximum depth of cut, and accompanying drawing 2 depicts state when electric circular saw is not in maximum depth of cut.Adjustable plate 4 is also provided with a locking mechanism, for locking it in the different anglecs of rotation.
In the present embodiment, can realize reducing the position that the length of electric circular saw and the technical characteristic of width are motors 2, this position is fixing, is exactly the angles of the axial line 21 of motor 2 specifically.Through overtesting, when adjustable plate 4 is in maximum depth of cut, when being also namely in the position shown in accompanying drawing 1, in a sharp angle α between the axial line of machine shaft 21 and adjustable plate 4 place plane.As can be seen from accompanying drawing 1-2, the length of electric circular saw obviously reduces, and as can be seen from accompanying drawing 3, the width of electric circular saw obviously reduces, more handy when user is used.Preferably, when this sharp angle α is more than or equal to 30 degree, the accessibility of instrument and operability optimum.In order to improve operability further, be respectively equipped with first handle 13 and second handle 14 at housing 1 away from above the side of saw blade and guard shield 12, user cosily can grip this two places handle and operate.
Compared to prior art, the present invention significantly reduces length and the width of electric circular saw when not affecting performance, improve accessibility and operability.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
