Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-4, a hexagon bolt with antiskid plain washer, includes hexagon bolt 1, plain washer 2, spacing post 4, spring 7 and spout 6, the cover is equipped with plain washer 2 in hexagon bolt 1 bottom, run through on the plain washer 2 and seted up slot 3, the interpolation of slot 3 is equipped with spacing post 4, top one side is equipped with slider 5 in the slot 3, the spout 6 that corresponds with slider 5 is seted up to spacing post 4 one side.

The spring 7 is sleeved on the limiting column 4 at the bottom in the slot 3, and the limiting ring 8 corresponding to the spring 7 is welded at the bottom of the slot 3.

In this embodiment, as shown in fig. 4, the limiting ring 8 is used for limiting the top of the spring 7 in the slot 3 to prevent the spring from falling off.

And one end of the nut of the hexagon bolt 1 is provided with a limiting jack 10 corresponding to the limiting column 4 in a penetrating way.

In this embodiment, as shown in fig. 1 and 3, the top of the limiting column 4 is inserted into the limiting insertion hole 10 to limit the hexagon bolt 1, so that the hexagon bolt 1 cannot rotate.
