专利汇可以提供Resilient retaining means for connecting work tools and work tool holders专利检索,专利查询,专利分析的服务。并且This invention resides in providing a resilient, ring-like member between a work tool and a work tool holder so as, in many cases, to permit relative motion, axial and/or rotative, between them. The work tool and work tool holder are intended for use primarily in connection with mining, excavating and earth working machines and the like. The work tool may comprise elongated elements having a shank portion with a working tip at one end and a gauge-determining abutment surface at at least the other end. The work tool holders may comprise bodies having a shank receiving perforation and means in association with the bottom of the perforation having an abutment adapted to cooperate with the abutment on the work tool. The ring-like member may be positioned in a groove on the work tool with a portion thereof adapted to abut some part of the work tool holder or it may be located in a groove in the work tool holder with a portion thereof adapted to engage a shallow depression or the like in the work tool. The resiliency and shape of the ring-like member permits the work tool to be forced into the work tool holder whereafter it will often be movable with respect thereto but captively held. The ring-like member may be formed of metal or plastic and may have a variety of shapes, for the most part, however, having a generally cylindrical, at least in part, configuration. The working portion of this resilient, generally cylindrical, ring-like retainer is capable of axial elongation whereby to present a knock-in, pryout relationship between the work tool and work tool holder.,下面是Resilient retaining means for connecting work tools and work tool holders专利的具体信息内容。
