Abstract
The invention relates to a handheld saw with a saw blade protector. The handheld saw is characterized by comprising a main body and a saw blade, wherein the saw blade is accommodated in a protection cover at the front end of the main body; and the handheld saw further comprises a saw blade protector, wherein one end of the saw blade protector is hinged to one end of the protection cover, and the hinged position is provided with an elastic part so as to extend the lower edge of the saw blade protector out of a blade part of the saw blade. The handheld saw with the saw blade protector disclosed by the invention has the advantages of simple structure and convenience in use, and can protect the saw blade effectively.
Description
Technical field
The hand-operated tools field that the present invention relates to relates in particular to a kind of Hand saw with saw blade protective device.
Background technology
Hand saw, a kind of as hand-operated tools, through being commonly used to carry out the cutting of tubular part, and when the cutting tubular part, because the saw blade of Hand saw is sharp, and saw blade extends beyond outside the cutter, damage exterior object easily when not using.
For this reason, designer of the present invention is because above-mentioned defective through concentrating on studies and designing, comprehensively is engaged in for a long time the experience and the achievement of related industry for many years, and research and design goes out a kind of Hand saw with saw blade protective device, to overcome above-mentioned defective.
Summary of the invention
The object of the present invention is to provide a kind of Hand saw with saw blade protective device, it is simple in structure, and is easy-to-use, can effectively protect saw blade, avoids damaging saw blade or exterior object.
For realizing above-mentioned purpose; The invention discloses a kind of Hand saw with saw blade protective device; This Hand saw comprises body and saw blade, and this saw blade is contained in the protective cover of body front end, it is characterized in that: this Hand saw also includes the saw blade protective device; One end of this saw blade protective device is articulated in an end of this protective cover, and articulated position is provided with elastic component extends beyond this saw blade with the lower edge with this saw blade protective device blade part.
Wherein: this elastic component is a disc spring.
Wherein: also be provided with degree of depth device for limiting at the protective cover top, this degree of depth device for limiting comprises the nut that is fixed in the protective cover top and cooperates with bolt and stretches in the protective cover and bolt that top corresponding and the saw blade protective device cooperates.
Wherein: body middle part has the rotation of switch with the control saw blade, is provided with in the body to drive the saw blade motor rotating and the rotation of motor is passed to saw blade to drive shaft drive.
Through said structure, the Hand saw with saw blade protective device of the present invention has the following advantages:
1, simple in structure, dismounting is convenient;
2, easy to operate, change quick;
3, can effectively protect saw blade, avoid damage saw blade.
The present invention will further describe in detail through following specific embodiment, and further combine will obtain knowing more and significantly understanding to the explanation of accompanying drawing.
Description of drawings
Fig. 1 has shown the front view with Hand saw of saw blade protective device of the present invention.
Fig. 2 has shown the operation chart with Hand saw of saw blade protective device of the present invention.
The specific embodiment
Referring to Fig. 1 and Fig. 2, shown the specific embodiment with Hand saw of saw blade protective device of the present invention.This Hand saw 10 comprises body 46 and saw blade 14; This saw blade 14 is contained in the protective cover of body 46 front ends; The body middle part has the rotation of switch with control saw blade 12; Be provided with in the body 46 to drive the saw blade motor rotating and the rotation of motor is passed to saw blade and drive the shaft drive (not shown), power line is stretched out in body 32 rear ends.Wherein, this Hand saw also includes saw blade protective device 24, and an end of this saw blade protective device 24 is articulated in an end of this protective cover; And articulated position is provided with elastic component 32 and extends beyond the blade part of this saw blade 14 with the lower edge with this saw blade protective device 24, thereby when not using this Hand saw, can surpass the characteristics of blade part through this saw blade protective device 24; Avoided the blade of saw blade that other objects are not intended to damage, and when workpiece 42 was cut, this saw blade protective device 24 fitted in the surface 40 of workpiece 42; And the body of Hand saw still stretches into to the inside of workpiece 42; Thereby cut (referring to Fig. 2), saw blade protective device 24 has then also been obtained the effect of collection of debris, has avoided flying around of chip; Preferably, this elastic component 32 is a disc spring.Preferably; Also be provided with degree of depth device for limiting at the protective cover top; This degree of depth device for limiting comprises the nut 60 that is fixed in the protective cover top and cooperates with bolt and stretches in the protective cover and bolt 58 that top corresponding and saw blade protective device 24 cooperates; Through regulating the built-in length of this bolt 58, can limit the degree of depth that saw blade 14 stretches into workpiece 50.
Can know that through foregoing description the present invention can effectively protect saw blade, can also adjust, not only prolong service life, also be applicable to the different depth cutting according to the degree of depth of cutting.
It is obvious that, and above description and record only are for example rather than in order to limit disclosure of the present invention, application or use.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the present invention does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of embodiment of the present invention, and scope of the present invention will comprise any embodiment of the specification that falls into the front and appended claim.
