Abstract

The invention provides a dual-purpose saw, which comprises a saw handle and a saw edge supporting structure, wherein the saw handle is provided with a handle for a hand to hold and a fixing column in front of the handle; the handle is fixedly connected with the fixing column; fastening screw holes are formed in the fixing column; the saw handle and the saw edge supporting structure are fixedly connected onto the fixing column through the fastening screw holes; a saw edge is a saw blade [2] or a saw plate [10]; a saw blade supporting structure is a bow-shaped part [1] with a bow back [b], a front cantilever [a] and a rear cantilever [c]; fastening screw holes are formed in the rear cantilever; a saw plate supporting structure is a clamping arm [9]; a gap in clearance fit with the thickness of the saw plate is formed in the front side of the clamping arm; fastening screw holes are formed in the clamping arm; and the fastening screw holes in the fixing column, the rear cantilever of the bow-shaped part and the clamping arm have the same layout and specification. The saw blade and the saw plate can be fixedly connected with the saw handle through fastening screws respectively, so that an operator can replace the saw edge as needed. Compared with the prior art, the dual-purpose saw is simple in structure, has no redundant parts, and does not block the visual line or interfere the operation.

Description

Dual-purpose saw

Technical field

What the present invention relates to is a kind of dual-purpose saw.

Background technology

In constructions such as installing, build, tend to need simultaneously to use common hacksaw (use saw blade) and plug in saw (using the saw plate), just needed the workman to carry two in the past and cut on-the-spot transposing use, if in crowded little space or in work high above the ground, can bring many inconvenience.So, people have proposed dual-purpose saw, as introducing in Chinese invention patent application " hacksaw frame " (publication number CN102728891), it " bow-shaped structural that consists of with the sagging front and back cantilever in front and back and the back of a bow is arranged; between the said arched back of a bow and front boom and back boom, detachable connection structure connects; and a collapsible saw plate holder is installed on back boom holds device, said collapsible saw plate holder is held mechanism and the linkage between back boom that device comprises mechanism, the clamping saw plate of clamping saw plate, the mechanism that stops hinge folding; The clamping face of the mechanism of clamping saw plate and bow-shaped structural place plane parallel, prevent from addition sawing in the mechanism of clamping saw plate plate the saw plate the mechanism of activity in the plane." be that this dual-purpose saw is comprised of saw handle and saw sword (comprising saw blade and saw plate) supporting mechanism, wherein the supporting mechanism of saw blade is bow-shaped structural, the supporting construction of sawing plate is that collapsible saw plate holder is held device.Hold device and be connected with linkage with saw frame due to collapsible saw plate holder wherein, it need to be turned back when being used for common hacksaw, in use may block vision, use inconvenience.

Summary of the invention

For above-mentioned deficiency, technical problem to be solved by this invention is when being used as respectively common hacksaw and plug in saw, and the saw that forms is all complete and without superfluous part, thereby a kind of dual-purpose saw that does not affect use that can select to install saw blade or saw plate is provided.

dual-purpose saw provided by the invention, saw handle and saw sword supporting mechanism are arranged, saw is the handle held being arranged and at the fixed leg in handle the place ahead, handle and fixed leg are fixedly linked, the holding screw hole is arranged on fixed leg, saw is being fixedly connected on fixed leg with holding screw with saw sword supporting mechanism, wherein sawing sword is saw blade or saw plate, the saw blade supporting mechanism is the camber member that the back of a bow and front boom and back boom are arranged, the holding screw hole is arranged on said back boom, the supporting mechanism of saw plate is a clamping limb, there is the seam with saw plate thickness matched in clearance the support arm front side, the holding screw hole is arranged on said clamping limb, said fixed leg, there are identical layout and specification in holding screw hole on camber member back boom and clamping limb.

Dual-purpose saw provided by the invention, saw blade and saw plate respectively have supporting mechanism, and both supporting mechanisms have the holding screw hole of identical topology and size, can be respectively with saw being fixedly connected with holding screw, make the operator can change as required the saw sword.Compared with prior art, the present invention is simple in structure, and not superfluous part can not block sight line or hinder operation.

Said clamping limb has identical shape and size with the camber member back boom, and at saw, fixed leg being installed on the position of sawing the sword supporting mechanism has the depression of making matched in clearance with the camber member back boom, locates, installs with convenient.

Said depression is arranged on fixed leg front side depression backward, and during installation, clamping limb or camber member back boom embed depression backward.

Said camber member is combined with screw by the back of a bow, front boom, back boom three parts, and wherein the back boom front side has with the seam of saw plate thickness matched in clearance simultaneously as the blade holder gripping arm.Volume when both having dwindled dual-purpose saw and carrying reduces again part.

Fig. 1 is the schematic diagrames of each parts of one embodiment of the invention when taking apart, and Fig. 2 is the structure chart when in Fig. 1, the part parts are assembled into common hacksaw, and Fig. 3 is assembled into structure chart when plugging in saw with part parts in Fig. 1, in figure: the 1-camber member, the 2-saw blade, 3-pull bar, 4-holding screw, the 5-clamp nut, 6-saws handle, 7-sheathing, the 8-sheath, the 9-clamping limb, 10-saws plate, 11-pull bar screw, 12-pad, 13-pull-rod nut, the a-front boom, the b-back of a bow, c-back boom.

The specific embodiment

One dual-purpose saw, as shown in Figure 1, comprise saw 6, camber member 1 and clamping limb 9.Wherein, camber member is to be connected to form by before and after front boom a, hunchbacked b and back boom c, and shape such as door font respectively have the tie rod hole of fore-and-aft direction in cantilever lower end, front and back, be separately installed with pull bar 3 and pull bar screw 11 and pad 12 thereof, pull-rod nut 13 on tie rod hole, in order to saw blade 2 tensionings.Clamping limb is the part identical with camber member back boom part, and its front side has width and saw plate 10 thickness to make the slot that matched in clearance, base and saw plate rear side are harmonious, and this seam can make the saw plate embed.Saw is approximate square shape, by the handle of holding with camber member is installed or the fixed leg of clamping limb is connected through the coupling part, up and down and forms, the fixed leg front side has the thickness of width and camber member or clamping limb to make the depression that matched in clearance, bottom surface and camber member or clamping limb trailing flank are harmonious.At fixed leg, camber member back boom, clamping limb and saw plate rear side, the holding screw hole that layout is identical and specification is identical is arranged, so insert in the fixed leg depression or the saw plate is inserted when inserting clamping limb in fixed leg again in the clamping limb line of rabbet joint when camber member, all available holding screw 4 and clamp nut 5 respectively with two groups saw fastening be as shown in Figure 2 common hacksaw and plug in saw as shown in Figure 3.Saw is being inserted in from back to front metal finishing cover 7 and rubber sheath 8.
