Description
Technical field
The utility model relates to a kind of electric tool, and particularly a kind of portable sweep-saw is used to cut timber, plastics, metal etc., is suitable for uses such as carpenter, industrial art worker, sculpture worker, wood pattern maker, pincers worker, upfitter and family especially.
Background technology
At present, comparatively common sweep-saw structure as shown in Figure 1, it comprises casing 1, be arranged on motor 2 in the casing 1, reducing gear 3, reciprocating lever mechanism 4 and the saw blade 7 by clamping ring 6 and reciprocating lever 5 connections of reciprocating lever mechanism 4, be located at the roller 8 and the base plate 9 that cooperate with the knife back of saw blade 7 of being used for of casing 1 bottom, wherein base plate 9 is installed in the bottom of casing 1, and its gradient can be adjusted according to actual needs.In when work, start pumps saw blade 7 earlier, and the thin plate that will desire sawing by the operator is pressed against on the workbench by base plate 9 then, it is walked according to curve that finished or requirement, thereby finish the sawing task.Above-mentioned sweep-saw of the prior art, it can only finish the cutting to plane curve, and for some have complicated solid surface as workmanship, sculpture etc. because sweep-saw can't go deep into, thereby just can not carry out among a small circle cutting processing to solid surface recited above; In addition, because saw blade 7 is exposed fully outside, therefore when operation, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is will provide a kind of can cut in the plane, and is that can cut among a small circle on the solid surface of any complexity again simultaneously and simple in structure, attaching/detaching is convenient, do not have that sight line is covered, safe and reliable omnipotent sweep-saw during operation.
The purpose of this utility model is achieved like this, a kind of omnipotent sweep-saw, it comprises casing 1, be arranged on the motor 2 in the casing 1, reducing gear 3, reciprocating lever mechanism 4 and the saw blade 7 that connects by the clamping ring 6 and the reciprocal reed 5 of reciprocating lever mechanism 4 and the roller 8 that cooperates with the knife back of saw blade 7 of being used for that is located at casing 1 bottom, be characterized in: below the leading section of described casing 1, have additional a sweep-saw head 9, the head of sweep-saw head 9 is narrow contract and its on the top be installed chew 10, the middle tool clamping ring reciprocating chamber 15 of sweep-saw head 9, before the central authorities of both sides and leading section offer respectively, back discharging opening 11,12 and saw blade hole 16, preceding, back discharging opening 11,12 and saw blade hole 16 communicate with clamping ring reciprocating chamber 15 respectively.
Connected mode between sweep-saw head 9 described in the utility model and the casing 1 is for removably connecting.
Recited above the removably connecting of the utility model is to be spirally connected.
Described in the utility model being spirally connected is to offer screw hole 13 on sweep-saw head 9, realizes being spirally connected with casing 1 in screw hole 13 backs of passing on the sweep-saw head 9 by hold-down screw 14.
The material of sweep-saw head 9 described in the utility model is a high-intensity resin.
The material of sweep-saw head 9 described in the utility model is any one in aluminium or the ironwork.
It is hard metal material that 10 material is chewed on top described in the utility model.
The utility model expands in a side of described clamping ring reciprocating chamber 15 and is provided with roller frame chamber 17, is equipped with roller 8 in it and is used to install the roller frame 19 of roller 8.
The utility model is because on the basis that does not change original sweep-saw structure, only below the leading section of sweep-saw casing 1, set up a sweep-saw head 9, make sweep-saw can not only realize the cutting of plane curve, and can be deep on the solid surface that original sweep-saw can't arrive by its narrow head that contracts, and chew 10 positioning action by the top of sweep-saw head 9 heads, can make saw blade 7 on solid surface, carry out among a small circle cutting; Simultaneously, because being shaped as of sweep-saw head 9 is up big and down small, thereby does not have sight line in the course of the work and stop, be convenient to the accurate cutting of operator in traveling process; Again, because saw blade 7 only expose the saw blade head when work, thereby security performance is good by 9 sealings of sweep-saw head; Again, the utility model also have grip convenience, good hand touch, seismaesthesia softly, installation or removal sweep-saw head 9 convenience, robust advantage.
Description of drawings
Fig. 1 is the structure chart in the original technology of the utility model.
Fig. 2 is an example structure figure of the present utility model.
Fig. 3 is the plane structure chart of Fig. 2.
The specific embodiment
See also Fig. 2, Fig. 3, a kind of sweep-saw, it comprises casing 1, motor 2, reducing gear 3, reciprocating lever mechanism 4, saw blade 7, roller 8 and sweep-saw head 9.In above-mentioned each parts, except sweep-saw head 9, all the other are original technology, therefore only simply narrate for the structure of original technology: in the drawings according to doing shown in the figure, motor 2, reducing gear 3, reciprocating lever mechanism 4 all is arranged in the casing 1 of sweep-saw, wherein the output of motor 2 is connected with described reducing gear 3, reciprocating lever mechanism 4 is connected with reducing gear 3, saw blade 7 connects by the reciprocal reed 5 of clamping ring 6 with reciprocating lever mechanism 4, roller 8 is articulated on the roller frame 19, roller frame 19 is installed on the holder 20 by adjusting screw 18, holder 20 is installed on the axle 21 of casing 1 bottom one side, offer knife back groove in the centre of roller 8, the knife back of saw blade 7 matches with the knife back groove of roller 8 centres.Here need to prove: the sweep-saw structure in the original technology of the utility model can change, and is not the restriction that is subjected to structure shown in the figure.
Please continue referring to Fig. 2, Fig. 3, sweep-saw head 9 of the present utility model can adopt generally that high-intensity resin is molded to form, can certainly adopt cast aluminium or iron frame structure, it is big that it is shaped as top, the narrow carp head that contracts in bottom, offer the clamping ring reciprocating chamber 15 that moves up and down for clamping ring 6 in the centre of sweep-saw head 9, the central authorities of both sides and leading section offer respectively communicate with clamping ring reciprocating chamber 15 before, back discharging opening 11,12 and saw blade hole 16, wherein, back discharging opening 11,12 be used for will bring into wood chip in the clamping ring reciprocating chamber 15, the plastics bits, metal fillings etc. discharge, saw blade hole 16 both play the guiding role to saw 7, pumped within it for saw blade 7 again.Simultaneously, for the ccontaining roller 8 that matches with saw blade 7 and be used to install the roller frame 19 of roller 8, also expand in a side of clamping ring reciprocating chamber 15 and to be provided with roller frame chamber 17.Top of the present utility model is chewed 10 and generally can be adopted metal material wear-resisting and that quality is harder to make, and the top is chewed 10 and is installed in the sweep-saw head 9 narrow heads that contract, and plays location and opposing impulsive force.
