Abstract
The invention relates to a hand-held saw with a saw blade protection device. The hand-held saw comprises a body and a saw blade, wherein the saw blade is accommodated in a protective cover which is arranged at the front end of the body. The hand-held saw is characterized by also comprising the saw blade protection device comprising an upper plate and a lower plate, and one side of the upper plate is hinged with one side of the lower plate; a plurality of through holes are arranged on the upper plate so as to allow the upper plate to be fixedly arranged outside the protective cover, and the lower plate is a rectangular plate body; and an inversed V-shaped notch is formed at the middle lower part of the lower plate so as to allow the blade part of the saw blade to be exposed to cut a tubular component. The hand-held saw has the advantages of simple structure and convenience in use, and can effectively protect the saw blade.
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 stretches out 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; 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, and this saw blade protective device comprises upper plate and lower plate, and a side of this upper plate and a side of lower plate are hinged; And have a plurality of through holes on this upper plate this upper plate is fixed to the outside of above-mentioned protective cover; This lower plate is the rectangle plate body, and its middle and lower part has the inverted V-shaped breach, and this breach can make the blade of saw blade expose so that tubular part is cut.
Wherein: the opposite side in this lower plate has extended upward the adjustment bar; Be sequentially set with a plurality of adjustment hole on this adjustment bar; And the opposite side of this upper plate has the pin-and-hole with this corresponding setting in a plurality of adjustment hole; And a bearing pin, this bearing pin can insert in this pin-and-hole and the arbitrary adjustment hole to confirm the position of the relative upper plate of this lower plate.
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, and, avoid damage saw blade at fixing tubular part of when cutting;
4, can adjust according to the diameter of tubular part, to adapt to the cutting of different tube diameters.
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 decomposing schematic representation 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 32 and saw blade 12; This saw blade 12 holds in the protective cover with body 32 front ends; The body middle part has the rotation of switch 36 with control saw blade 12; Be provided with in the body 32 and drive the saw blade motor rotating, the rotation of motor is passed to saw blade drives the shaft drive (not shown), power line 40 is stretched out in body 32 rear ends.
Wherein, This Hand saw also includes saw blade protective device 14; This saw blade protective device 14 comprises upper plate 16 and lower plate 18; One side of this upper plate 16 and a side of lower plate 18 are hinged, and have a plurality of through holes on this upper plate 16 this upper plate 16 is fixed to the outside of above-mentioned protective cover, and the middle part of this upper plate 16 has semi-circular through hole to hold the fixture of saw blade 12.
This lower plate 18 is the rectangle plate body, and its middle and lower part has the inverted V-shaped breach, and this breach can make the blade of saw blade 12 expose so that tubular part 100 is cut; Thus; Saw blade 12 can not expose outside the lower plate 18, thereby has avoided the damage to other objects in when operation, simultaneously; This inverted V-shaped breach can carry out a location to tubular part, has avoided rocking in the cutting.
Preferably, extended upward adjustment bar 20, be sequentially set with a plurality of adjustment hole on this adjustment bar 20 at the opposite side of this lower plate 18; In the drawings, order is provided with four adjustment holes 24,26,28,30, and the opposite side of this upper plate has the pin-and-hole with this corresponding setting in a plurality of adjustment hole; An and bearing pin 21; This bearing pin 21 can insert in this pin-and-hole and the arbitrary adjustment hole, to confirm the position of these lower plate 18 relative upper plates 16, through such adjustment; The length that adjustable saw sheet 12 stretches out in this reverse V-shaped groove is cut with the pipe to different-diameter.Can know that through foregoing description the present invention can effectively protect saw blade, can also cut, not only prolong service life, also be applicable to different pipe cuttings according to different pipes.
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.
