[0020] like Figures 1 to 7As shown, a fastening bolt that can be quickly engaged includes a fastening fitting seat 1 with a hexagonal outer side, a cylindrical main body combined connecting column 2 with the same central axis on the right side of the fastening fitting seat 1, and a fastening threaded matching groove on the outer side of the main body combined connecting column 2. When in use, the outer side can be fastened like an existing bolt-like structure. A central avoidance safety hole 3 is provided at the center position of the right end face of the main body combined connecting column 2, which can meet the matching requirements of the central position combined structure and ensure that the central position has a ventilation function. A conical locking matching connecting groove 4 is provided at the center position of the left end face of the fastening fitting seat 1. When the central position component is matched, it can be quickly installed by locking, ensuring that the operation during assembly is more convenient and the matching efficiency is higher. A cylindrical combined avoidance groove 5 that is connected to the central avoidance safety hole 3 is provided on the right side of the locking matching connecting groove 4, ensuring that the space at the center position is larger and the matching smoothness of the components is better during matching. The left side of the locking and matching connection groove 4 is provided with a locking and matching plate 6 which is oriented to the right and evenly distributed on the circumference. Through this structure, it can be locked and connected with the structure of the center matching. The locking and matching plate 6 is tilted and distributed along the taper angle direction of the locking and matching connection groove 4, which can have a better guiding effect during installation, making the operation during matching more convenient. It adopts a brand-new structural design, improves the structure of the existing bolt, sets a safety hole and a locking and matching groove inside the inner bolt, and sets a matching plate that can be connected by locking. When in use, the center position can be quickly combined with the installation position by locking, and the outer position can be connected in the form of bolts. The operation during the overall installation is more convenient, which can solve the matching and connection requirements of complex component installation, has better safety during internal combination, better anti-loosening combination effect, and higher connection efficiency during overall combination, which can meet the combination connection requirements in various application environments.

[0021] Preferably, the left side of the snap-fit ​​connection groove 4 does not exceed the plane where the left end surface of the fastening fitting seat 1 is located, so that the structural support strength of the snap-fit ​​connection groove 4 is better and the service life during use is longer.

[0022] Preferably, the diameter of the combined avoidance groove 5 is larger than the diameter of the circular structure at the right end surface of the locking and fitting connecting groove 4, so that a second anti-loosening fitting structure can be formed at the edge of the intersection, thereby improving the overall stability of the internal locking and fitting.

[0023] Preferably, a spare matching guide chamfer structure is provided at the outer edge position of the center avoidance safety hole 3, which can provide a guiding matching function when the center position matching structure is installed and assembled as needed, making the assembly operation more convenient.

[0024] Preferably, the vertical length of the locking fitting plate 6 in the left and right directions is less than or equal to one third of the left and right depth of the locking fitting connecting groove 4. If the vertical length is too large, the strength of the locking structure will be affected and the locking and anti-loosening effect will be reduced.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
