Abstract
The utility model relates to a dust-proof cover for electric impact drills, which is trumpet-shaped and is composed of two conical springs, an outer sleeve, an inner sleeve, a bearing and a cylindrical spring. When users drill holes on ceiling with an impact electric drill, the utility model can be firstly arranged on a drill bit clamp of the impact electric drill. In the process of drilling hole, the dust fallen from the ceiling can be collected by the utility model, so the dust on the ceiling can not fall on heads, faces and bodies of operators. The utility model can also be conveniently disassembled when not used and is suitable for being used as a dust-proof cover when users drill holes on the ceiling with the impact electric drill.
Description
The utility model belongs to a kind of dust cover, particularly belongs to a kind of dust cover that is used with electric impact drill.
Not having dustproof dress cover on the existing electric impact drill, when on ceiling, holing with electric impact drill, the head that the dust on the ceiling can directly drop on the operator upward, on the face and on one's body, this makes troubles to operation.
In order to solve people when using electric impact drill on ceiling, to hole, prevent the head that dust on the ceiling drops on the operator go up, on the face and on one's body, task of the present utility model is a kind of dust cover that can be contained on the electric impact drill of design, this dust cover can will be caught from the dust that ceiling falls, overcome when holing on ceiling with electric impact drill, the dust on the ceiling directly drops on operator's head and goes up, on the face and shortcoming on one's body.
Task of the present utility model is finished as follows: the electric impact drill dust cover is horn-like shape, and it is made up of 2 taper springs, overcoat, interior cover, bearing, 1 cylindrical spring.Wherein the height of a taper spring is higher, the height of another taper spring is lower, overcoat is enclosed within on the highly higher taper spring, interior being enclosed within on the highly lower taper spring, the microcephaly of highly higher taper spring end is fixed together with the stub end of highly lower taper spring, an end of cylindrical spring respectively, and bearing is located at the little head end of highly lower taper spring.In the time of will on ceiling, holing with electric impact drill, earlier be fixed on the electric impact drill dust cover on the drill jig of electric impact drill by cylindrical spring, in boring procedure, when drill bit pierces in the ceiling gradually, highly higher taper spring and cylindrical spring can be compressed, and highly lower taper spring can be stretched.In boring procedure, the dust that falls on the ceiling can be caught by the electric impact drill dust cover, the head of having avoided dropping on the dirt on the ceiling operator goes up, on the face and on one's body.In the time of need not using the electric impact drill dust cover, can take off from electric impact drill very easily.
The dust cover that the utility model is particularly suitable as electric impact drill when holing on ceiling.
