[embodiment]
See also Fig. 1 to shown in Figure 3, the invention provides the connection fastening piece 100 that presses that a kind of sheetmetal sheet metal part is used, it is provided with rounded bolt head 10, is positioned at the lengthwise type screw rod 20 of the first side of bolt, reaches the joint 30 that connects described screw rod and bolt head.
Described bolt head 10 is an anti-rotation colored tooth bolt head that presses, it is provided with a supporting surface 11 that is held in sheetmetal sheet metal part 200 and reaches the end face 12 opposing with supporting surface 11, described supporting surface 11 is rounded, and be provided with a round platform 13 and spend 14 from some teeth that round platform 13 radially extends, described tooth is spent 14 self-supporting face 11 projections, and the circumferencial direction along supporting surface 11 is evenly distributed, and described tooth spends 14 to be radially and to extend, and described tooth spends 14 root to be connected to described round platform 13 places; Described round platform 13 is connected with described joint 30, and round platform 13 is around the periphery of described joint 30.
Described lengthwise type screw rod 20 is for the regular screw threads screw rod or scribble locking glue regular screw threads screw rod, and the one end is connected with described joint 30 one, and the other end is free end.
Described joint 30 is between described screw rod 20 and bolt head 10, and one-body molded with described screw rod 20 and bolt head 10, be used for connecting described screw rod 20 and bolt head 10, described joint 30 is provided with press groove 31 and be positioned at the positioning ring 32 of groove 31 1 sides that press of an annular, wherein, the described groove 31 that presses arranges near described round platform 13, and described positioning ring 32 arranges near described screw rod 20.One side of described positioning ring 32 is provided with an inclined-plane 33 that is connected to described screw rod 20, and described inclined-plane 33 and the groove 31 that presses lay respectively at the both sides of described positioning ring 32.
