Dog excrement pick=up device - has tubular housing with spring slider to extend foldable linkage which forms triangular bag support
Реферат: The dog-excrement pick-up device consists of a tubular housing in which slides a rod. One end of the rod is joined to a retractable handle. The slide piece (7) supports a set of links (15, 16) which can be contained within the housing in their withdrawn position, and can jut out from the free end of the housing for use. The links support a paper bag, thereby forming a kind of spade. The end of the slide piece on the side of the free end of the tubular piece has a cover supporting two parallel pivot pins (13, 14). On each of the pins is hinged one end of a first pair of links which at their other end are hinged to an end of a link hinged onto a nut (20). The nut forms part of one end of a rod (24) with a stop piece (25) on its free end against which a compression spring (26) acts.
