Pneumatically operated impact-action self-propelled reversible mechanism
专利汇可以提供Pneumatically operated impact-action self-propelled reversible mechanism专利检索，专利查询，专利分析的服务。并且There is disclosed a pneumatically operated impact-action selfpropelled reversible mechanism for driving holes in the earth by compacting the soil around the hole being made, comprising a housing having a pointed end and receiving thereinside an impact member delivering successive impacts upon the housing, as this impact member is reciprocated interiorly of this housing in operation of the mechanism under the action of compressed air, the mechanism further including a compressed air supply sleeve connected with an air conduit member and threadedly secured in a nut for axial displacement relative to this nut, when the air conduit member is rotated. According to the invention, the nut, associated with the compressed air supply sleeve, has a plurality of longitudinal oblique slits made therein, these slits defining therebetween a pair of resiliently deformable cantilever members projecting axially beyond the adjacent face end of the nut, the longitudinal axial lines of these cantilever members extending in opposition to the direction of the displacement of the compressed air supply sleeve, when the latter is screwed into the nut, these cantilever members being adapted to engage an abutment of the compressed air supply sleeve, as the latter is screwed into the nut.，下面是Pneumatically operated impact-action self-propelled reversible mechanism专利的具体信息内容。
