[0020] like Figures 1 to 7As shown, a locking type fastening nut includes a nut main body structure 1 with a regular hexagonal main body, and a cylindrical center combination connection hole 2 at the center of the nut main body structure 1, which are the basic structures of the nut. An integral cylindrical installation stop stabilizing column 3 is provided on the left end face of the nut main body structure 1, which ensures the structural strength of the left position and can be used as a stop structure for later tightening. A cylindrical combination locking stabilizing column 4 is provided at the center position of the left end face of the installation stop stabilizing column 3, and an integral conical locking connection matching column 5 with the same central axis is provided on the left side of the combination locking stabilizing column 4, which is the main matching structure during locking installation. The size of the right end face of the locking connection matching column 5 is larger than the diameter of the combination locking stabilizing column 4, which ensures better matching stability after the locking combination and has a locking and anti-loosening matching effect. A cylindrical center avoidance connection groove 7 is provided at the left center position of the locking connection matching column 5, which ensures a larger space at the left center position. An integral snap-fit connection installation groove is formed between the right side of the snap-fit connection fitting column 5 and the installation stop stabilizing column 3. The left side of the snap-fit connection fitting column 5 is provided with a safety avoidance fitting groove 6 that is evenly distributed around the circumference and penetrates the central avoidance connection groove 7 and the outer side of the whole. The deformation of the fitting structure is easier during the overall snap-fitting, and the material cost in the production process can be effectively saved. The left side of the central combination connection hole 2 penetrates the left side of the installation stop stabilizing column 3. When in use, it can be fastened and matched with the mechanical component by a threaded connection, and then the overall snap-fit connection is performed through the snap-fit structure. The snap-fit structure can be used as an overall installation quick combination structure for assembly connection, or as an anti-loosening structure for overall tightening for double tightening combination. It has greater flexibility in tightening connection, higher efficiency in fitting and installation, and more reliable overall combination strength. The assembly combination position occupies less space, which can meet the tightening connection requirements of high-strength complex components.

[0021] Preferably, the left edge position of the installation stop stabilizing column 3 is provided with a safety chamfer structure for avoiding the matching position when performing the positioning combination, thereby ensuring that the matching position has a larger space and the matching operation is more convenient.

[0022] Preferably, the right end face of the avoidance safety fitting groove 6 coincides with the left end face of the installation stop stabilization column 3, so that the space of the overall avoidance safety fitting groove 6 is larger, the deformation space during the overall locking is also larger, and the matching efficiency can be further improved.

[0023] Preferably, a combined sealing safety groove is provided at the left edge of the central combined connecting hole 2, which can cooperate with components such as a sealing ring to perform overall sealing during assembly, thereby improving safety during later use.

[0024] Preferably, the outer cylindrical diameter of the installation stop stabilizing column 3 is larger than the diameter of the circumscribed circle of the nut main body structure 1, so that the strength of the left structure is better, the combination safety during cooperation can be further improved, and the bearing capacity of the fastening position is stronger.

[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 described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
