FIELD OF THE INVENTION [0001] The present invention relates to a replaceable reciprocating work head, for example a brush head for use in an electric tool assembly such as an electric brush assembly. BACKGROUND OF THE INVENTION [0002] It is often desirable to remove small dirt patches and spots from fabrics such as carpets and this is often conventionally carried out manually using a scrubbing brush or using a vacuum cleaner with a brush attachment. Manual scrubbing may be labour intensive and once the bristles on the brush have worn down the brush must be discarded. The use of a conventional vacuum cleaner may be difficult in some circumstances as the vacuum cleaner is a generally cumbersome device and not suitable for use in all locations. [0003] Thus there is a need for a low cost modular replaceable reciprocating work head such as a brush head for use in an electric tool, such as a brush, of small size. SUMMARY OF THE INVENTION [0004] According to a first aspect of the invention there is provided a reciprocating work head for use with an electric tool assembly comprising: [0005] a movable section; and [0006] a fixed section having a longitudinal axis, the movable section carrying a retaining pin; wherein the movable section is arranged to move along the retaining pin in a reciprocating motion along the longitudinal axis of the fixed section. [0007] According to a further aspect there is provided an electric brush assembly comprising the reciprocating work head defined above. BRIEF DESCRIPTION OF THE DRAWINGS [0008] Preferred features of the invention will now be described, for the sake of illustration only, with reference to the following figures in which: [0009] FIG. 1a is a plan view showing the bristle side of a brush head according to a first preferred embodiment of the invention; [0010] FIG. 1b is an elevation of the brush head according to FIG. 1a; [0011] FIG. 1c is a plan view of the other side of the brush head to that shown in FIG. 1a; [0012] FIG. 2 is a parts exploded view of the brush head of FIGS. 1a to c showing the assembly method; [0013] FIG. 3 is a cross-sectional view through the brush head of FIGS. 1a to c; [0014] FIG. 4 is a sectional view through a longitudinal centreline of the brush head of FIG. 3; [0015] FIG. 5a is a perspective view of the bristle side of a brush head having bristles at one extreme position according to a first preferred embodiment of the invention; [0016] FIG. 5b is a perspective view of the other side of the brush head of FIG. 5a in the same position as that shown in FIG. 5a; [0017] FIG. 6a is a perspective view of a bristle side of a brush head with bristles at another extreme position; [0018] FIG. 6b is a perspective view of the other side of the brush head of FIG. 6a in the same position as the brush head of FIG. 6a; [0019] FIG. 7a is a projection showing the underside (non-bristle side) of the brush head attached to a brush drive assembly; and Continue reading about Replaceable reciprocating work head and an electric tool assembly comprising a reciprocating work head...
