Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the present invention.

The utility model provides a joint seam indicates the gap between its relative two terminal surfaces when two sections bolts constitute an organic whole.

Example 1

Referring to fig. 1 to 5, fig. 1 is a schematic structural diagram of the whole structure of the present embodiment, and fig. 2 is a schematic structural diagram of a bolt of the present embodiment; FIG. 3 is a schematic structural view of an insert of the present embodiment; fig. 4 is an enlarged view of the portion of fig. 1.

The fastening kit comprises a bolt 1, a nut 2, an insert 11 and a screw 3. The bolt 1 comprises a threaded section provided with a thread and a smooth shank section provided with no thread.

The outer wall of the embedded block 11 is provided with threads, the outer wall of the thread section is provided with a groove 12 extending along the axial direction of the bolt 1, the embedded block 11 and the groove 12 are in sliding connection in a nesting mode, and the nut 2 can be in threaded connection with the bolt 1 and the embedded block 11 simultaneously after connection, as shown in figure 1.
