Abstract
The invention provides a hacksaw frame which is provided with an arched structure comprising front and back cantilevers which are sagged transversely and an arch back, wherein the arch back 2, the front cantilever 1 and the rear cantilever 9 of the arched structure are connected by adopting a detachably-connected structure; a foldable hacksaw plate clamping device is arranged on the rear cantilever and comprises a mechanism for clamping the hacksaw plate, a hinge mechanism between a mechanism for clamping the hacksaw plate and the rear cantilever as well as a mechanism for preventing the hinge from being folded; a clamping surface of the mechanism for clamping the hacksaw plate is parallel to a plane where the arched structure is positioned; and a mechanism for preventing the hacksaw plate 3 from moving on the plane where the hacksaw plate is positioned is also arranged in the mechanism for clamping the hacksaw plate. Compared with the prior art, the hacksaw frame disclosed by the invention can be suitable for two types of hacksaw frames, and thus tools carried by operators are simplified and the utilization rate of materials is increased.
Description
Technical field
What the present invention relates to is a kind of hacksaw frame.
Background technology
Hacksaw frame is in order to forming the tool assembly of hacksaw behind the fixing saw blade, and hacksaw has common hacksaw to also have a kind of plug in saw outward, and the main distinction of two kinds of hacksaws is in the hacksaw frame the fixedly structure of saw blade.The ordinary steel saw frame has bow-shaped structural, and sagging cantilever is the front and back installation strong point of saw blade before and after it.Have only a handle and plug in saw, the saw plate is fixed on last with screw with the hole of rear end, and saw blade can be worn hole or the seam reserved in the workpiece and carry out operation its front end is slotting.Above-mentioned in the past two kinds of hacksaws need be equipped with two kinds of different hacksaw frames, and promptly the operating personnel need carry two hacksaw frames, and is cumbersome.
Summary of the invention
To above-mentioned deficiency, the present invention will provide a kind of hacksaw frame that can form two kinds of form hacksaws.
Hacksaw frame provided by the invention; Have with front and back sagging front and back cantilever and the hunchbacked bow-shaped structural that constitutes; The dismountable type syndeton connects between the said arched back of a bow and front boom and the back boom; And a collapsible saw plate holder is installed on back boom holds device, said collapsible saw plate holder is held device and is comprised the mechanism of clamping saw plate, the mechanism of clamping saw plate and the mechanism that the linkage between the back boom, prevention hinge fold; The clamping face of the mechanism of clamping saw plate and bow-shaped structural place plane parallel prevent to saw plate movable mechanism on plane, saw plate place in addition in the mechanism of clamping saw plate.
Hacksaw frame provided by the invention; The back of a bow of ordinary steel saw frame and front boom be designed to the form that to shirk with back boom; On back boom, set up collapsible saw plate holder again and held device; Make it can be fit to install saw blade and saw plate,, perhaps shed the saw plate and the saw plate holder of turning back is held device and just can be used as and plug in saw or common hacksaw uses as long as when using or shed saw blade and the back of a bow and front boom.Compared with prior art, the present invention goes for the hacksaw of two kinds of forms, thereby simplifies the entrained instrument of operating personnel, improves the utilization rate of material.
Said collapsible saw plate holder hold device with the quiet positioning seat of back boom one, moving positioning seat and the pivot formation linkage that quiet positioning seat and moving positioning seat is hinged; Connect and compose the saw plate holder with the holding piece that covers whole linkage with screw and linkage and hold mechanism, and wherein holding piece still stops the folding mechanism of hinge.This is simple and compact for structure, and cost is economized simple to operate.
On quiet positioning seat, moving positioning seat, holding piece thrin or a plurality of clamping face, projection is arranged, rising height is less than the saw plate thickness, and sawing simultaneously has the hole of matching with projection to lack on the plate.Perhaps, be connected screw more than two between holding piece and the linkage.Aforementioned structure is to prevent to saw plate movable mechanism on plane, saw plate place.
Description of drawings
Fig. 1 is the structure chart of one embodiment of the invention, and Fig. 2 is a hinge fraction structure chart among Fig. 1, among the figure: the 1-front boom, the 2-back of a bow, 3-saws plate, the 4-holding piece, 5-moves positioning seat, 6-pivot, 7-projection, 8-handle, 9-back boom, 10-saw blade, the quiet positioning seat of 11-.
The specific embodiment
One double-purpose hacksaw frame is like Fig. 1, shown in 2.The bow-shaped structural that constitutes with front boom 1, the back of a bow 2 and back boom 9 is arranged, be fixed with again 8 after the bow-shaped structural, wherein bow-shaped structural is that the back of a bow is inserted before and after the back in the cantilever upper end hole and fastening and constitute with screw, so hunchbacked and front boom can be separated back boom.Saw blade 10 two ends are installed between the cantilever of front and back.Back boom middle part make a string frontal arc after the small semicircle table top, and according to string axis hole is set and constitutes quiet positioning seat 11, and the projection 7 that in its table top arc, the dentation layout is arranged is as clamping face.Other has a greater part of round lobe to be moving positioning seat 5, also is provided with axis hole and complementary with the axis hole at small semicircle string place according to string, and the clamping face of moving positioning seat is concordant with the clamping face of quiet positioning seat.With pivot 6 with the hinged formation linkage of sound positioning seat; The moving positioning seat of formed linkage inwardly (clamping face one side) is folded to quiet positioning seat and can not makes two outwards to fold above 180 °; Be that both are pivotally mounted in table top one side, its thickness forms the structure that stops outer folding.Having a size circular holding piece 4 identical with linkage to process with the holding piece is the butterfly screws shape (form that holding piece and screw are fixing) of pad, has screw to cooperate with said screw at moving positioning seat circle centre position.Because holding piece merges with screw with quiet moving positioning seat simultaneously mutually both are fixed, make hinge lose folding ability of mind.Saw plate 3 has circular-arc rear end, and the profile of tooth breach is arranged, and circle centre position is porose, and the clamping face of this saw plate rear end shape and linkage matches, and will saw after the plate rear end is fixed on the linkage with holding piece, and it is firmly motionless to saw the relative saw frame of plate.
During use, as be used as common hacksaw and use, can holding piece be backed out, take off the moving positioning seat of turning back behind the saw plate, just saw blade work can not hindered.As be used as and plug in saw and use, can saw blade Panasonic be separated being connected of the back of a bow and back boom again, just the work of sawing plate can not hindered.
2, a hinged clamping device on back boom has three holes will saw plate and fixes with screw in the clamping device, between clamping device and the back boom locator card is arranged.
