Abstract: An inserted connection member for a train connector includes an insertion needle, an insulator, a disconnection preventing pad and an extrusion block. The insulator is sequentially provided with a positioning hole and an inserted connection hole in an axial direction. The insertion needle includes a line connecting segment, a positioning segment and an inserted connection segment which are connected sequentially, the line connecting segment and the positioning segment are arranged in the positioning hole. The disconnection preventing pad and the extrusion block are both sleeved on the line connecting segment, and the disconnection preventing pad includes a pad body and a boss arranged on the pad body. Thus, the insertion needle is ensured to maintain a stable contact even when the train is running at a high speed, and a disconnection preventing effect of the insertion needle is achieved.

Abstract: A skin treatment device comprising a skin polishing head to remove skin from a treatment area, a collection bin disposed within the housing and positioned to collect the skin removed by skin polishing head, a conduit disposed adjacent to the skin polishing head and the housing, the conduit being in fluid communication with the collection bin, and a drive mechanism coupled to the skin polishing head, rotation of the drive mechanism simultaneously driving the skin polishing head and creating suction to urge skin removed by the skin polishing head through the conduit and into the collection bin.
