Description
Technical field
The utility model relates to a kind of hand electric cutting operation machine, relates in particular to a kind of electric circular saw.
Background technology
In forestry; furniture is made and hardware; in the pipe fitting processing; use electric saw through regular meeting and carry out cutting operation; large-scale seat formula electric saw power is bigger; saw face cutting force is strong; be applicable to large-sized sheet material; the cutting processing of pipe fitting; and in the daily life; often need be to small-sized timber; the metal tube member carries out cutting operation; adopt large-scale seat formula electric saw this moment; not only inconvenience is used in carrying; and exist cutting type and be not easy to shape; the defective that yardstick is finely tuned; therefore hand-held electric saw uses comparatively extensive in to daily cutting operation and life; but traditional hand-held electric saw volume is still bigger; use heavy; in the last few years; small and exquisite for volume; easy to carry; use the market demand of mini electric saw flexibly also day by day vigorous; but thing followed problem is; the tradition hand-held electric saw is for ensureing safety in utilization; its switch adopts the substep operating structure; release and two step of work structure promptly are set on switch; need first pull switch to unlock in the use; Push switch start work again; but this kind volume of switch is bigger; can't be installed in mini electric saw and use, influence the microminiaturization of mini electric saw, and the moving switch of finger embedding always in the use of this kind switch; the long-time operation finger can be felt to ache, and causes work fatigue easily.
The utility model content
The purpose of this utility model provides a kind of electric circular saw, solved the technological deficiency that adopts existing hand-held electric saw switch can't accomplish electric saw volume, weight microminiaturization, and the utility model is simple in structure, use portable and smart, dependable performance, not only realize the microminiaturization of electric circular saw, also effectively reduced the labour intensity in the electric saw operation simultaneously.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of electric circular saw comprises body, and described body is connected and composed by bottom deck assembly, hand-held housing, saw blade, motor, head capsule, movable shield, is respectively equipped with switch I and switch I I on the described body 1.
Further, described switch I and switch I I are located at the heteropleural of described head capsule respectively.
After described head capsule both sides are respectively equipped with switch I and switch I I, needn't adopt traditional big switch can be when guaranteeing security, reliability, realized the build weight microminiaturization of electric circular saw, and the required power of Push switch is little when using, the fatigue that the finger of having avoided long period of operation to cause is ached and caused has reduced labour intensity.
Further, described motor power connection end I connects with inductance I, electric saw switch I; Described motor power connection end II connects with inductance II, switch I I, also is connected with the electric capacity with described motor parallel between described inductance I, II.
Further, switch I and switch I I adopt microswitch.
Preferably, described motor adopts and exchanges series excited machine.Because electric circular saw has strict requirement to volume and weight, therefore adopt to exchange series excited machine, when satisfying electric saw and requiring, can provide bigger power output for motor volume weight, satisfy job requirements; And exchange series excited machine and more be applicable to the machinery that need start repeatedly, shut down.
Preferably: described hand-held housing is provided with the anti-skidding moccasin of hand shape, meet the ergonomics requirement, be convenient to grip, can effectively avoid the user in use for some time because the electric saw that the hand cunning causes slip, when having improved operation quality, avoided the landing of portable electric saw, improved the comfort of using, reduce labour intensity, further improved the safety in utilization of electric saw.
Further, described saw blade adopts round saw.
The utility model adopts said structure, head capsule heteropleural at electric circular saw is respectively equipped with switch I, the II that constitutes the loop, effectively reduced and solved conventional switch and can't be installed in the technological deficiency of using on the mini electric saw, and the utility model sound construction, machinery, circuit connect simple and reliable, grip comfortablely, have reduced user's labour intensity, alleviated sense of fatigue, be applicable in small-sized cutting operation production and daily life and use.
Description of drawings
Figure 1 shows that the structural representation that the utility model switch is provided with;
Figure 2 shows that the connection diagram of the utility model circuit part.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of electric circular saw of the utility model, comprise body, described body is connected and composed by bottom deck assembly, hand-held housing, saw blade, motor 2, head capsule 1, movable shield, be respectively equipped with switch I 11 and switch I I 12 on the described body, described switch I 11 and switch I I 12 are located at the heteropleural of described head capsule 1 respectively, described switch I 11 and switch I I 12 adopt microswitch, described motor 2 adopts and exchanges series excited machine, the hand-held housing of described electric saw is provided with anti-skidding moccasin, and described saw blade adopts round saw.
As shown in Figure 2, described motor 2 power connection end I connect with inductance I 21, switch I 11; Described motor power connection end II connects with inductance II 22, switch I I 12, and 22 of described inductance I 21, II also are connected with the electric capacity 3 in parallel with described motor 2.
When electric circular saw with after power supply is connected, during use, need be after switch I 11 and switch I I 12 all connect, circuit can constitute the loop, motor 2 begins to drive saw blade work, thereby in the microminiaturization that has realized electric circular saw, has guaranteed the reliability of the security and the use of electric saw.And the utility model structure is small and exquisite, in light weight, meets principle of human engineering, and holding operation is lighter, and the operation of long period also is difficult for causing user's fatigue, has alleviated labour intensity.
