Description

A kind of hand-rail type bow saw
Technical field
The present invention relates to cutting equipment technical field, particularly relate to a kind of hand-rail type bow saw.
Background technology
Manual bow saw is made up of an additional fixing hacksaw blade fixed mechanism of hacksaw blade usually, lighter in weight, low price, can one man operation, is therefore widely used in actual production.Manual bow saw of the prior art moves back and forth only by manual operations, easy generation skewness, can not control position and the angle of saw blade preferably, cause cutting accuracy lower during sawed-off material, section is irregular, can not produce effective sawed-off operation when bow saw is moved in pushing hands forward by hand simultaneously, efficiency is lower, and saw blade is easily damaged, in addition, in prior art, manual bow saw in use, is not easy to fix by workpiece for sawing, is easily subject to the restriction of geogen and is not suitable for one man operation.
Authorization Notice No. is in the patent document of CN203936463U, disclose a kind of manual saw with brace and connecting rod framework, comprise manual saw body, bracing frame, rocking bar, rocking arm and connecting rod, wherein, manual saw body comprises saw bow and saw blade, saw bow is fixed with anticreep plate, bracing frame is provided with vertical rod, the upper end of one end of rocking bar and this vertical rod is rotationally connected, rocking bar is also provided with brace and two slide bars be arranged in parallel, the two ends of two slide bars are connected respectively by a distance plate, and saw bow is slidably connected between two slide bars by anticreep plate; Bracing frame is provided with two gripper shoes be arranged in parallel; rocking arm is provided with crank, crank is arranged between two gripper shoes, and one end of crank and this connecting rod is rotationally connected mutually; one end of saw bow is provided with a connecting hole, and the other end of connecting rod and this connecting hole are rotationally connected mutually; This utility model also comprises fixture and material support bar, and horizontally disposed and one end and this vertical rod middle part of material support bar is mutually permanently connected, and fixture is fixedly connected with this material support bar.By hand-turning rocking bar during use, manual saw body is moved back and forth thus reaches the object of cutting, this technical scheme is passed through with brace and connecting rod framework, effectively can reduce the operation complexity of operating personnel, simple to operate, cutting accuracy is higher, cost is lower, section is neat, and not fragile saw blade, be easy to one man operation simultaneously.
The manual saw with brace and connecting rod framework of above-mentioned prior art, anticreep plate in cutting process on saw bow can produce larger frictional resistance in sliding process back and forth on slide bar, this frictional resistance constantly hinders the relative motion of person between anticreep plate and slide bar, make the reciprocating motion that manual saw in use can not be smooth, impact uses feel, and then affects cutting efficiency; When the diameter of workpiece for sawing larger or less time, be difficult to manual saw body to be adjusted to suitable position, thus make the scope of application of prior art less; In addition, during use, saw blade can only remain on a line of cut and move back and forth, workpiece for sawing is cut off as wanted, need the angle constantly being adjusted manual saw body by the elasticity of the countershaft changing vertical rod and rocking bar, great inconvenience is brought to user, the irregular problem of section may be caused, reduce cutting efficiency simultaneously.
Therefore, how can improve the existing manual saw with brace and connecting rod framework, be that those skilled in the art have technical barrier to be solved.
