Abstract
The invention discloses a hacksaw for cutting metal or nonmetal objects. The hacksaw comprises a handle, a saw bow and a saw blade. The saw bow is provided with a front arm saw head, a rear arm saw head, a hollow front saw bow and a hollow rear saw box, the hollow front saw box is connected with the hollow rear saw box telescopically, saw blade mounting heads are transversely arranged at the tail ends of the front arm saw head and the rear arm saw head, a saw bow fastening device is arranged at the telescopically-jointed position of the hollow front saw bow and the hollow rear saw bow, and saw blade clamping devices are arranged on the saw blade mounting heads. The broken saw blade at least 16 centimeters long can be reusable, and resources of saw blades can be saved.
Description
Technical field
The invention belongs to a kind of pincers worker hand cutting tool, particularly belong to a kind of hacksaw.
Background technology
Hacksaw is the conventional pincers worker hand cutting tools of a kind of people, existing hacksaw generally comprises handle, saw frame and saw blade, some hacksaws can also regulate the distance between saw bow and saw blade, but the hacksaw of these kinds in use, all that the circular hole at saw blade two ends is fixedly connected with the steady pin that saw frame two ends arrange, in the time of cutting object, the particularly starting stage, sometimes the problem that saw blade can fracture, for the saw blade fractureing because its one end or two ends no longer have circular hole, thereby the steady pin that cannot arrange with saw frame two ends is again fixedly connected with, can only throw aside and cause waste.
Summary of the invention
Technical problem to be solved by this invention is: a kind of hacksaw is provided.Use this hacksaw at least 16 centimeter length saw blades after fractureing can be reused, save saw blade resource.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of hacksaw, comprise handle, saw bow body and saw blade, described saw bow body has forearm saw head, postbrachium saw head, in saw bow after unprecedented saw bow and hollow, in this, unprecedented saw bow is connected with saw bow after hollow is flexible, this forearm saw head, the end of postbrachium saw head is horizontally arranged with saw blade mounting head, it is characterized in that: in described, unprecedented saw bow is provided with saw bow fastener with the flexible position being connected of saw bow after hollow, in described saw blade mounting head, be provided with saw blade clamping apparatus, described saw bow fastener by the threaded circular hole that arranges on unprecedented saw bow proximal end one side and the set bolt matching with this circular hole form, described saw blade clamping apparatus is by two jig arm that arrange in saw blade mounting head, the threaded screw that this jig arm side arranges and the fishbolt matching with this screw form.
As the preferred scheme of one, described saw bow fastener be two and respectively corresponding arrange with in the both sides of unprecedented saw bow and the flexible position being connected of saw bow after hollow, after described hollow, saw bow is disposed with at least 2 pits away from two relative sides of one end of postbrachium saw head.
Use procedure of the present invention is: unscrew the set bolt of saw bow fastener and the fishbolt of saw blade clamping apparatus, at least 16 centimeter length saw blades after fractureing are positioned over respectively in the saw blade mounting head of end horizontally set of forearm saw head, postbrachium saw head in two jig arm, and adapt with it according to the collapsing length of saw bow after unprecedented saw bow and hollow in the corresponding adjusting of the length of saw blade, tighten the set bolt of saw bow fastener and the fishbolt of saw blade clamping apparatus and can use this hacksaw to carry out cutting work.
The invention has the beneficial effects as follows: because unprecedented saw bow in this hacksaw is provided with saw bow fastener with the flexible position being connected of saw bow after hollow, in saw blade mounting head, be provided with saw blade clamping apparatus, at least 16 centimeter length saw blades after fractureing can be installed easily and adapt with it according to the collapsing length of saw bow after unprecedented saw bow and hollow in the corresponding adjusting of length of the saw blade of installing, tightening the set bolt of saw bow fastener and the fishbolt of saw blade clamping apparatus can use this hacksaw to carry out cutting work, the at least 16 centimeter length saw blades of having realized after making to fracture are reused, save the object of saw blade resource.
Again due to by the saw bow fastener of this hacksaw be two and respectively corresponding arrange with in the both sides of unprecedented saw bow and the flexible position being connected of saw bow after hollow, and saw bow is disposed with at least 2 pits away from two relative sides of one end of postbrachium saw head after hollow, can regulate easily saw bow body and the hacksaw blade that is arranged on saw frame body to prevent that in a plan-position distortion from appearring in the saw blade after installation, and by the anchor stud head of saw bow fastener hold out against with hollow after in the pit that sets gradually of two sides of saw bow, the fastening effect of saw bow after unprecedented saw bow and hollow in having increased.
