[0014] In the figure: 1 end portion, 2 rod portion, 3 second end portion, 4 second rod portion, 5 limiting groove, 6 fixing groove, 7 through opening, 8 positioning plate, 9 limiting plate, 10 pad, 11 second pad. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 and Figure 2 As shown, a combined bolt fastener structure includes a bolt member and a connector. The bolt member includes an integrally formed end 1 and a rod 2, the rod is provided with threads on the outside, and the connector includes an integrally formed second end 3 and a second rod 4. A thread groove is provided in the middle of the end face of the second rod toward one side of the second end, and the rod is adapted to the thread groove. A plurality of evenly arranged limiting grooves 5 are provided at the end of the second rod, and the limiting grooves penetrate the limiting groove and the outer side of the second rod. A fixing groove 6 is provided in the middle of the end face of the end toward one side of the rod, and through openings 7 are evenly arranged circumferentially on the rod, and the through openings are connected to the fixing groove. A positioning plate 8 is provided in the fixing groove, and the positioning plate is tightly fitted with the fixing groove to achieve a stable connection. The positioning plate is connected to a limiting plate 9, and the limiting plate passes through the through opening, and the limiting plate is locked with the limiting groove.

[0017] Furthermore, the limiting plate has an L-shaped cross section, including a connecting portion and a limiting portion, the connecting portion passes through the through opening and is connected to the positioning plate, and the limiting portion is inserted into the limiting groove. The limiting plate is detachable relative to the positioning plate for easy assembly.

[0018] Furthermore, four groups of limit grooves, through holes and limit plates are provided. This facilitates the stable connection between the bolt member and the connecting member. The bolt member only needs to be adjusted by a quarter turn to ensure that the limit plate is embedded in the limit groove, thereby ensuring the tightness of the connection. The rod portion and the second rod portion are respectively penetrated with a pad 10 and a second pad 11.

[0019] The end of the positioning plate is provided with a fixing hook groove, which is convenient for adjusting the positioning plate using tools in an external position.
