Abstract
The utility model discloses a carbon brush for an electric tool. The carbon brush comprises a carbon brush body, wherein a wire is led out from the interior of the carbon brush body, the tail end of the wire is connected with a copper sheet, a spring is sleeved at the periphery of the wire, one end of the spring is fixed on the carbon brush body, and the other end of the spring is fixed on the copper sheet. The carbon brush provided by the utility model has the advantages that the carbon brush body is clamped on a metal support, and the spring is sleeved at the periphery of the wire, the spring closely presses the wire on a rotating shaft, so that in mechanical operation, great shock is generated, but the carbon brush has less possibility of falling off; and the service life is long.
Description
Technical field
The utility model relates to carbon brush, relates in particular to a kind of electric tool and uses carbon brush.
Background technology
Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, and it generally is that pure carbon adds coagulating agent and processes, and external form generally is a square, is stuck on the metallic support.Some carbon brush structure is simple, and it is pressed in the rotating shaft, because mechanical rotation produces bigger shaking force, comes off easily, and shorten the useful life of carbon brush.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of the utility model provides a kind of difficult drop-off, and the electric tool of long service life is used carbon brush.
The technical scheme that the utility model adopts is:
Electric tool is used carbon brush, comprises the carbon brush body, leads to lead in the said carbon brush body, and said wire end is connected with copper sheet, and said lead periphery is with spring, and said spring one end is fixed on the carbon brush body, and the said spring other end is fixed on the copper sheet.
Said lead is a copper core flexible cord.
Said carbon brush body be shaped as cuboid or square.
The beneficial effect of the utility model: the carbon brush body is stuck on the metallic support, and the lead periphery is with spring, and it is pressed on spring handle in the rotating shaft, during machine work, produces huge vibrations, also difficult drop-off, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, carbon brush body, 2, lead, 3, copper sheet, 4, spring.
Embodiment
