Abstract
The utility model relates to the improvement of a protective device structure of an oblique cutting saw. The utility model comprises a fixed protective cover arranged at the upper half part of a saw blade and a movable protective cover arranged at the lower half part of the saw blade, wherein the root of the movable protective cover is hinged with the fixed protective cover; at least one side of the lower end of the moveable protective cover is provided with a roller mechanism; the roller mechanism is composed of a stationary shaft fixed on the movable protective cover and a roller arranged on the stationary shaft. The utility model has the characteristics of reasonable design, simple structure, capability of increasing the effective cutting height of an oblique cutting saw, etc.; the utility model mainly solves the technical problems that when the movable protective cover touches a workpiece in the prior art, the movable protective cover can not be opened, the saw blade can not cut down continuously and the effective cutting height of the oblique cutting saw is limited.
Description
Technical field
The utility model relates to a kind of diagonal cutting saw, especially relates to a kind of improvement to diagonal cutting saw protector structure.
Background technology
Diagonal cutting saw the time injures operator or other people for preventing saw blade work, is provided with blade guard, and blade guard comprises the fixed blade guard of being located at saw blade the first half more and is located at the flexible blade guard of saw blade the latter half.Flexible blade guard is designed to: during the downward cut workpiece of diagonal cutting saw, along with the downward cutting of saw blade, flexible blade guard is progressively opened, and exposes saw blade so that cutting.As shown in Figure 5, in the process of cut workpiece, workpiece 5 has been run in flexible blade guard 1 lower end, causes flexible blade guard 1 can't continue to open, and saw blade 4 can't continue downward cutting, has limited effective cutting-height of diagonal cutting saw.This patent structure such as figure two are provided with roller 3 in the one or both sides of protective cover 1, and when saw blade 4 during in cutting downwards, pulley 3 rolls on workpiece 5, thus protective cover 1 can open, saw blade 4 can continue downward cutting.
Summary of the invention
It is a kind of reasonable in design that the utility model purpose is to provide, simple in structure, can improve the diagonal cutting saw side roller device of effective cutting-height of diagonal cutting saw, mainly be to solve in the prior art when flexible blade guard is run into workpiece, cause flexible blade guard can't continue to open, saw blade can't continue downward cutting, has limited the technical problem of effective cutting-height of diagonal cutting saw.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: comprise the fixed blade guard of being located at saw blade the first half and the flexible blade guard of being located at saw blade the latter half, the root and the fixed blade guard of described flexible blade guard are hinged, at least one side in the lower end of described flexible blade guard is provided with idler wheel mechanism, and described idler wheel mechanism is made of the roller that is fixed in the fixed axis on the flexible blade guard and be located on the fixed axis.When cut workpiece, when workpiece was run in the lower end of flexible blade guard, roller rolled at surface of the work, can make flexible blade guard continue to open, and saw blade continues cutting downwards, had improved effective cutting-height of diagonal cutting saw.
As preferably, the both sides, lower end of described flexible blade guard are equipped with idler wheel mechanism.
As preferably, the end of described fixed axis is provided with the opening spring, and described roller is limited on the fixed axis by the opening spring.
As preferably, described fixed axis and flexible blade guard are injected into one; The outer end of described roller is provided with chamfering, and the tapering α of this chamfering is 30 °-60 °; The tapering α preferred values of described chamfering is 40 °-50 °.In the roller outer end chamfering is set, when diagonal cutting saw carries out oblique cutting to workpiece, can prevents that roller and workbench from colliding.
Therefore, the utlity model has reasonable in designly, simple in structure, can improve the characteristics such as effective cutting-height of diagonal cutting saw.When cut workpiece, when workpiece was run in the lower end of flexible blade guard, roller rolled at surface of the work, can make flexible blade guard continue to open, and saw blade continues cutting downwards, had improved effective cutting-height of diagonal cutting saw.In the roller outer end chamfering is set, when diagonal cutting saw carries out oblique cutting to workpiece, can prevents that roller and workbench from colliding.
