[0020] like Figures 1 to 7 As shown, an amorphous transformer assembly fastening nut includes a conical main body fastening and fitting seat 1 with a central axis in the left-right direction, and an integrally formed cylindrical reinforcement fitting column is provided at the right position of the main body fastening and fitting seat 1, so that the structural strength of the right position is higher. The diameter of the reinforcement fitting column is the same as the diameter of the right end face of the main body fastening and fitting seat 1, which is more convenient during production and processing, and can be processed in one piece with the forming mold. A cylindrical central assembly fastening hole 2 that runs through the right side of the whole is provided at the center position of the left end face of the main body fastening and fitting seat 1, and a fastening combination thread groove is provided inside the central assembly fastening hole 2, which is fastened and assembled with a screw rod. The outer conical surface of the main body fastening and fitting seat 1 is provided with an arc-shaped hand-held matching operation groove 3 that is evenly distributed around the circumference and completely penetrates the left and right directions of the whole body, and is fastened and matched by manual operation. After fastening, anti-loosening glue is applied on the screw rod, so there is no need to fasten vigorously with a fastening tool. The left side of the main body fastening and fitting seat 1 is located between two adjacent handheld fitting operation slots 3 and is provided with a wiring avoidance fitting hole 4 which is arc-shaped and completely penetrates the entire body in the left and right directions, so that components such as wiring harnesses can pass through as needed. The right end face of the reinforcement fitting column is provided with a conical combination precision fitting column 5 evenly distributed around the circumference, which can be accurately combined with the fitting pad or other fastening components at the fastening position, and can drive the fitting components to rotate and fasten together during the later fastening, so that the mutual fit is better, the position accuracy is higher, and the fitting structure will not be damaged during the fastening process. It adopts a brand-new structural design, and can be tightened and matched manually when in use. By setting a combined precise matching column on the main structure, it can be accurately combined with the sealing gasket or the positioning holes on the matching parts during the assembly process, and can be rotated together with the tightening of the nut body, ensuring the tightness of the mutual fit and making the sealing and waterproof performance of the connection position higher. By setting wiring avoidance matching holes on its main structure, it can pass through the wiring harness as needed after tightening, thereby playing a role of avoidance, eliminating the need for winding the wiring harness, saving the cost of the wiring harness, and making the tightening more efficient.
[0021] Preferably, the length of the fastening combination thread groove is the same as the length of the central assembly fastening hole 2 in the left-right direction, ensuring a larger space for internal fastening cooperation and a better overall fastening effect.
[0022] Preferably, the left and right edge positions inside the central assembly fastening hole 2 are respectively provided with matching avoidance chamfer structures, which have a guiding function during matching and ensure that the combination operation during matching is more convenient.
[0023] Preferably, a handheld anti-skid structure is provided on the inner side of the handheld cooperation operation groove 3, which may be an anti-skid boss or an anti-skid groove or the like, which has a reliable anti-skid effect when hand-held cooperation is performed and has better stability during operation.
[0024] Preferably, the combined precision matching column 5 is located between the hand-held matching operation slot 3 and the wiring avoidance matching hole 4, so that the strength of this structure is higher and the bearing capacity is stronger when used in combination.
[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.
