Abstract
The utility model provides an angle grinder. The lower end of the middle cover of a bearing chamber is provided with an axial position limit trough; the upper end of the middle cover is provided with protection cover rotary positioning troughs at every certain angle; the edge of the middle cover is nonuniformly provided with protection cover installation positioning troughs; the middle part of the protection cover is fixed with a spring leaf with a convex rib; the internal side of a clamp ring wall is provided with positioning ribs with the same quantity, the same distribution angles and diameters equal to that of the protection cover installation positioning troughs. Therefore, a protection cover with fast conversion positioning and self-locking function is formed. The rotary protection cover can conveniently adjust the angle of the protection cover, and can be removed by lifting the spring leaf of the protection cover by virtue of a tool, with convenient application.
Description
Technical field
The utility model belongs to electric tool.
Background technology
Electric angle grinder is widely used in grinding, cutting, engraving of metal and stone material etc., owing to be handheld tool, add its work under bad environment, for guaranteeing operating personnel's safety, sanding machine all is provided with protective cover above emery wheel, be used to control machining angle and prevent that emery wheel from hurting sb.'s feelings.Prior art is the side that the defence guard shield is fixed on the outer bearing chamber of output shaft, and this structure makes that adjustment sanding machine protective cover angle is very inconvenient, and each adjustment need be retightened protective cover with instrument.
Summary of the invention
The purpose of this utility model is to provide a kind of protective cover angle can be quick, the sanding machine of convenient conversion, as shown in drawings, electric angle grinder is by motor, transmission system, decelerator, composition such as output shaft and protective cover, output shaft has bearing chamber outward, of the present utility model being characterised in that in truncated cone-shaped middle cover of bearing fixed outdoor, the lower end of middle cover has the axial limiting groove one, there is an annular ridge middle cover upper end, there is a protective cover rotation locating slot in the relative center of circle every the angle of determining on the annular ridge, there is the protective cover of several non-uniform Distribution that locating slot is installed on the middle cover upper end-face edge, there is a snap ring centre of protective cover, a spring leaf is fixed at the middle part of snap ring, have on the spring one downward, can drop on the convex tendon in the locating slot, snap ring wall inboard has quantity and protective cover installation locating slot to equate, identical with the diameter mutually positioning bar of distribution angle of distribution angle and diameter and protective cover installation locating slot.After positioning bar on the protective cover snap ring and the installation locating slot on the middle cover aligned vertically with defeating protective cover to the axial limiting groove of middle cover, the rotation protective cover can be in place protective cover, convex tendon on the protective cover upper spring sheet drops in the protective cover rotation locating slot, and the rotation protective cover can be adjusted the angle of protective cover easily.Spring leaf provides protective cover location and the needed pressure of self-locking.Lift by the spring leaf of instrument during dismounting, can unload protective cover, easy to use.
