Specific embodiment
In order that those skilled in the art can be further understood that feature of the present utility model and technology contents, with reference to
Drawings and embodiments elaborate to this utility model embodiment.
As shown in figure 3, be the structural representation of this utility model embodiment bolt 1, including：Bolt head 11, light bar portion
12 and ridge portion 13, also have in groove 14, the groove 14 below the ridge portion 13 and there is compression spring
141st, connecting rod 143 and be fixed in the connecting rod 143, fan shape baffle 142 that can be freely movable；The compression spring
141 are fixed between the side of the groove 14 and the fan shape baffle 142；The two ends of the connecting rod 143 and the groove 14
Bottom land interference fit, the fixed-direction of the connecting rod 143 is parallel with the groove side.
It should be noted that in this utility model embodiment, light bar portion 12 is only the convenient of processing technology, therefore this practicality
Light bar portion 12 can also not be included in the bolt that new embodiment is provided；Further, ridge portion 13 can be used for and nut screw connection
It is fixed, and the nut inner ring has the female thread coordinated with the ridge portion 13.
In order that the fan shape baffle 142 is large enough to hold in the space of the groove 14, the receiving space of the groove 14 is big
In the volume of the fan shape baffle 142.
Further, in order to easily facilitate the activity of fan shape baffle 142, the one end of the compression spring 141 is fixed on the fan
On one side of shape baffle plate 142.
Specifically, as shown in Figure 3 and Figure 4, the one end of the compression spring 141 is fixed on of the fan shape baffle 142
Bian Shang.Further, as shown in figure 3, fan shape baffle 142 is in free state, and the fan shape baffle 142 is worked as in free state
When, some is located at outside groove 14 for the arc of fan shape baffle 142, and this state is that fan shape baffle 142 launches to greatest extent.When
During bolts and nuts secure fit, fan shape baffle 142 is touched first, with the compression stress of the deep and compression spring 141 of nut,
Fan shape baffle 142 is compressed in groove 14, specifically as shown in figure 4, further, when nut inner thread and the spiral shell of ridge portion 13
Close to a certain extent, the exposed section of groove 14 of bolt goes out, and fan shape baffle 142 is strutted again, reaches state as shown in Figure 3.
This utility model embodiment additionally provides a kind of fixed structure, and the fixed structure includes：Nut 2, the first connector
3rd, the bolt 1 described in the second connector 4 and this utility model；The bolt 1 through first connector 3, described the
