Fig. 1 to Fig. 3 is referred to, now a kind of embodiment of anti-drop bolt provided by the utility model is illustrated.One
Kind anti-drop bolt, including bolt head 1, shank of bolt 2, groove 3 and the nut for preventing from being arranged on the shank of bolt 2 come off
Anti-drop device 4, the bolt head 1 and the vertical connection of shank of bolt 2, be provided with external screw thread 5 on the shank of bolt 2, it is described
Groove 3 is arranged on the end face of the shank of bolt 2, and the bolt head 1 is located at the other end of the shank of bolt 2, the anticreep
Device 4 includes buckle 6, the cylindrical connecting rod 7 being connected with the buckle 6 and the anti-drop head being connected with described one end of connecting rod 7
8, the buckle 6 is engaged by clamping with the groove 3.
The bolt head 1 is hexagonal bolt head, in use, passing through spanner clamping bolt head 1 first so that shank of bolt 2 is twisted
It is tightened to by the screwed hole in fastener, then nut is screwed on shank of bolt 2, finally sticks into the buckle 6 on anti-drop device 4
