Description

A kind of handsaw

Technical field

The utility model relates to handsaw, particularly a kind of handsaw of simple and compact for structure, the practical demand that satisfies numerous consumer groups.

Background technology

The sawing material of this hand TT tool widespread usage commonly used of handsaw in repair of machine, assembling.Traditional handsaw is generally by saw blade, parts such as saw beam and handle are formed, its structure has multiple, the structure that has is too simple, assemble not compact, practicality is relatively poor, service life is shorter, be easy to damage, for disclosing a kind of hacksaw frame, the CN2207902Y utility model patent just belongs to this kind as notification number, comprise the back camber beam that fuses, handle and shell on the back, can with back camber beam camber beam before diverse location is relatively-stationary, be installed on the camber beam of back, fixedly sell the movable back of saw blade one end, and on preceding camber beam, before the fixing fixed structure of the saw blade other end, fixed structure are positioned on the camber beam one end small stair, be shaped with preceding camber beam integrated punching, two axis are mutually the blind rivet of 90 degree.And the function ratio that has is more powerful, but structure is too complicated, mainly satisfy the multi-functional handsaw that uses under complex environment or the specific condition, as the applying date is that the Chinese invention patent application 200410066922.9 on March 23rd, 2005 discloses hand saw capable of light guiding orientation cutting and just belongs to this kind, and the support body that comprises has foregrip, support body is put the beams in place and the back handle; LED lamp and back LED lamp before support body is put the beams in place and is provided with, back handle is embedded with battery case, the push button switch that can insert button cell, realizes light guiding orientation cutting; Back handle is fitted with a monkey wrench, monkey wrench is embedded with floatless switch, switch spring, monkey wrench and movable sleeve are by the steady pin pin joint, the bar loading later round pin of back blind rivet penetrates rear spring, and with the movable sleeve that penetrates rear spring apical grafting mutually, the movable sleeve rear end is embedded with split washer, is provided with lining ring between back handle and monkey wrench; Be provided with adjusting nut before the through hole of foregrip lower end, adjusting nut is equipped with embedded nut, and pre-installed round pin of preceding blind rivet passed the back angle ratchet of adjusting saw blade sawing angle, preceding angle ratchet, front spring, preceding interior cover in proper order; Back angle ratchet matches with preceding angle ratchet, and sawing angle 0 to 360 degree is at random adjusted.This patent of invention complex structure, cost is higher, can not satisfy numerous consumer groups' demand.

Summary of the invention

Technical problem to be solved in the utility model is at above-mentioned defective, and a kind of handsaw of simple and compact for structure, the practical demand that satisfies numerous consumer groups is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of handsaw, comprise handle, saw bow and equipped saw blade through casting forming, and handle has lever, support arm and sets a roof beam in place, and the saw bow leading section is shaped on the fixedly preceding blind rivet of saw blade; The technical measures of taking comprise: the handle lower front end is shaped on forward the through hole that extends, and the notch that this handle through hole rear outside has can be inserted securing member, this handle through hole front portion pass the adjusting rod that is shaped on the back blind rivet and securing member mutually line connect.

For optimizing technique scheme, the measure of being taked also comprises:

For assemble firm closely, the saw bow rearward end is shaped on and can be embedded in set a roof beam in place shank in the front end notch of handle.

For light use and gain in strength, handle is that metallic aluminium or aluminium alloy compression casting are shaped, and for ease of holding, makes things convenient for the user to operate, and the handle lever is injected with plastics or the rubber layer of being convenient to hold.

For simple and practical, securing member is an adjusting nut.

Be weight reduction, support arm is shaped on the ripple glaze of being convenient to hold, and the handle bottom is shaped on the alternate notch of convex-concave.

Compared with prior art, the utility model is shaped on forward the through hole that extends by the handle lower front end, and the notch that this handle through hole rear outside has can be inserted securing member, this handle through hole front portion pass the adjusting rod that is shaped on the back blind rivet and securing member mutually line connect.The installing/dismounting saw blade only need screw and unscrew securing member and get final product.Its loading and unloading saw blade is convenient, the demand that satisfies numerous consumer groups in light weight, simple and compact for structure, with low cost, practical.
