Description

Five metals hacksaw frame that fracture saw blade is continuous to connect fast

Technical Field

The invention relates to the technical field of hardware tools, in particular to a hardware hacksaw frame with a fracture saw blade capable of being rapidly spliced.

Background

Hacksaw, be the common tool of pincers worker, cut off less size round steel, the angle steel, band steel and work piece etc. mainly include sash and saw blade two parts, install the saw blade on the sash during the use, current hacksaw blade all is provided with the hole generally at both ends and is used for installing with the sash, and hacksaw blade's material leads to its cracked condition can appear often in the use, the most common mode is just carrying out the change of just having a mere chance at the strip when meetting hacksaw blade fracture under the normal condition.

The technical proposal not only causes the waste of resources, but also can not reuse the broken hacksaw blade, and when no replaceable hacksaw blade is available in the construction process, the hacksaw needs to wait for being purchased again, which wastes time, Chinese patent discloses a hacksaw (patent number: CN 104191040A), the utility model comprises a handle, a saw bow body and a saw blade, wherein the saw bow body is provided with a front arm saw head, a rear arm saw head, a hollow front saw bow and a hollow rear saw bow, in the technical scheme, a hollow front saw bow is connected with a hollow rear saw bow in a telescopic way, the tail ends of a front arm saw head and a rear arm saw head are transversely provided with saw blade mounting heads, saw bow fastening devices are arranged at the telescopic connection positions of the hollow front saw bow and the hollow rear saw bow, saw blade clamping devices are arranged on the saw blade mounting heads, the technical scheme can mainly reuse the broken saw blade with the length of at least 16 cm, thereby saving the saw blade resource.

The above technical solution does enable the secondary fixing and use of a broken hacksaw blade without fixing holes, but still has significant drawbacks: if the part of hacksaw frame bottom installation hacksaw blade still relies on hacksaw blade's support to carry out the fixed of shape, uses the hacksaw to draw the in-process, and the holistic stability of hacksaw relies on the bolt extrusion of its clamping device department completely, though can carry out the regulation of flexible length, nevertheless the extrusion force also causes the hacksaw frame very easily to take place deformation influence holistic stability simultaneously, causes hacksaw blade's fracture more easily on the contrary.
