Abstract

The invention provides a combined hacksaw frame which is composed of an arch-shaped beam and a handle. The arch-shaped beam comprises a front suspension arm, an arch back and a rear suspension arm, the lower end of the front suspension arm and the lower end of the rear suspension arm are respectively provided with a fastening device for saw blades, the arch back and the rear suspension arm are fixedly connected with the handle, the front suspension arm (2) of the beam is in inserted and sleeved connection with the arch back (4) through a bevel sleeve, the bevel sleeve is a hollow pipe formed by bending over the upper end of the front suspension arm backwards, and the bevel position of the front end of the hollow pipe is provided with an upward protrusion. According to the combined hacksaw frame, the front suspension arm of the arch-shaped beam is detached into independent parts and is connected with the arch back through the bevel sleeve, and the upward protrusion is arranged at the bevel position, so that the front suspension frame becomes a portable saw frame. Compared with the prior art, the combined hacksaw frame has the advantages that a small insert saw can be separated from an ordinary saw frame and when a hacksaw needs to be used in a smaller space, saws do not need to be additionally carried. Improvement of the working efficiency and quality is facilitated.

Description

The combination hacksaw frame

Technical field

What the present invention relates to is a kind of combination hacksaw frame.

Background technology

In order to be convenient for carrying use, especially ascend a height or pierce in little space and use hacksaw, multiple similar tools is combined integrated, especially two kinds of saw swords are combined on a saw frame.If any a kind of combination hacksaw frame, by bow beam and handle, formed, the front and back cantilever of its central sill and the back of a bow are dismountable types, and combining saw frame when complete is common hacksaw, and removing forearm and the back of a bow can be as plugging in saw.But the plug in saw handle portion of this combining form is excessive, also lacks and hold sense while using inconvenience and operation.

Summary of the invention

For above-mentioned deficiency, technical problem to be solved by this invention is that the hacksaw that heavy and light is different is combined in a hacksaw, proposes a kind of removable multi-purpose combination hacksaw frame that is divided into.

Combination hacksaw frame provided by the invention, by bow beam and handle, formed, bow beam comprises front boom, the back of a bow and back boom, respectively there is the fastener that saw blade is installed cantilever lower end, front and back, wherein the back of a bow is fixedly connected with handle with back boom, the front boom of beam is connected with sleeve through between knuckle cover and the back of a bow, and said knuckle cover is the hollow pipe of turning back backward in the front boom upper end, and there is the projection made progress at hollow pipe front end knuckle place.

Combination hacksaw frame provided by the invention, be split as independent part by the front boom of bow beam, and be connected with the back of a bow with the knuckle cover, and projection is upwards arranged at the knuckle place, makes front boom become a light saw frame.This saw frame be take hollow pipe and partly is handle, and front boom is beam, and slotting saw blade is arranged on the front boom lower end downwards, and the projection at knuckle place is to be pressed in stopping on tiger’s jaw, so that the application of force while using.Compared with prior art, the present invention, from common saw frame, isolating a small-sized plug in saw, needn't separately be with saw while making in less space, to use hacksaw.Be conducive to increase work efficiency and quality.

On said front boom, be equipped with and buckle, specifically the rivet of a band is fixed on front boom, in order to the front boom under dismounting and institute coupling part system thereof can be hung over it the operator when operation.

Said hunchbacked front end has saw blade fastening device, and the distance between the saw blade fastening device of this saw blade fastening device and back boom lower end is identical with length of saw blade.Saw blade can be installed form the triangle saw after shedding front boom between back boom lower end and hunchbacked front end, can also directly by plugging in saw blade, be arranged on forward the plug in saw of the large shape of hunchbacked front end composition.

The accompanying drawing explanation

Fig. 1 is the diagram that the part of one embodiment of the invention is broken state, Fig. 2 is with one of saw of part composition in Fig. 1---common hacksaw, Fig. 3 is with two of the saw of part composition in Fig. 1---three corner saws, Fig. 4 is with three of the saw of part composition in Fig. 1---large-scale plug in saw, Fig. 5 is with four of the saw of part composition in Fig. 1---light plug in saw, in figure: 1-front boom sheath, the 2-front boom, 3-buckles, the 4-back of a bow, the 5-pivot, the 6-handle cover, the 7-bottom, the 8-snap close, 9-saw blade tensioner arm, 10-saw blade hook, 11-long saw bar, 12-saw blade hook, 13-plugs in saw blade.

The specific embodiment

As shown in Figure 1, this example combination hacksaw frame by front boom sheath 1, front boom 2, buckle 3, saw frame main body, pivot 5, handle cover 6, bottom 7, snap close 8, saw blade tensioner arm 9, rear saw blade hook 10, front saw blade hook 12 that the back of a bow 4 and handle, back boom form form.The saw blade tensioner arm is by pivot knuckles on back boom, and snap close is arranged on handle, at its lower end and is connected with saw blade tensioner arm lower end.Cantilever lower end before and after front and back saw blade hook is arranged on respectively.Back of a bow front end is a flat square body, and there is the hollow pipe of turning back backward the front boom upper end, this hollow pipe and hunchbacked front end matched in clearance.Phase shortage button on spring leaf and hunchbacked front end is arranged in hollow pipe, interlock and produce the anticreep resistance when both are inserted mutually.Front boom has extension upwards at the place of turning back, namely hollow pipe front end upside has protrusion, and hollow tube profiles is applicable to holding, and makes to form the handle that claims hand.Have the front boom sheath can be enclosed within outside front boom, it also has knuckle, and after putting, the part protection except lower end by the hollow pipe of front boom part and front boom, make to improve feel, prevent from hurting sb.'s feelings and improving aesthetic feeling.Handle cover protects outside handle and bottom is used for covering the handle bottom and hooks molecular saw blade fastening device with snap close, saw blade tensioner arm and rear saw blade.The saw blade fastening device that the front boom lower end is comprised of former saw blade hook and pressing plate, also hook nail and pressing plate saw blade fastening device at hunchbacked front end.The hollow pipe rear portion that front boom is turned back is fixed one and is buckled, and mouth hanging is that a short column is riveted on tube wall, and the short column upper end is porose, has a ring to be through on hole.

By whole parts assemblings, can form common hacksaw as shown in Figure 2, long saw bar 11 is installed between cantilever lower end, front and back.Shed front boom long saw bar formation three corner saws as shown in Figure 3 can be installed between back boom lower end and hunchbacked front end, or install and insert the large-scale slotting certificate that saw blade 13 forms as shown in Figure 4 at hunchbacked front end.If install in the front boom lower end with the front boom unloaded, plug in saw blade form light plug in saw as shown in Figure 5.
