The purpose of this utility model can also reach by the following technical programs:
A kind of embodiment of the present utility model is: described dextrorotation bolt is a hexagon head bolt.
A kind of embodiment of the present utility model is: the screw leading portion internal diameter of described thread-hole part is big, the back segment internal diameter is less, and described screw back segment internal diameter is slightly larger than the external diameter of left-handed bolt, and described screw leading portion internal diameter is slightly larger than the external diameter of dextrorotation bolt.
A kind of embodiment of the present utility model is: the external diameter of the described plain tube mouth of pipe is slightly less than the internal diameter of the head bore cap of dextrorotation bolt.
The utlity model has following outstanding beneficial effect:
1, the utility model is owing to be provided with left hand thread section and right-hand thread section simultaneously in a thread-hole part, screw in left-handed bolt and dextrorotation bolt simultaneously, extruding expanding riveted takes place by plain tube and hole cap in left-handed bolt and dextrorotation bolt simultaneously, with connected piece and firm the connecting together of thread-hole part, thus realize connected piece locking/antitheft function and effect.
2, therefore the utility model can realize automation because purposes is wide, consumption is big, production line production in enormous quantities, and automatic production degree height can obtain high economic benefit.
