[0020] like Figures 1 to 7As shown, a position-limiting stainless steel fastening structure includes a cylindrical main fastening stud 1 with a central axis in the up-down direction, and a fastening connection thread groove 2 is provided on the outer cylindrical surface of the main fastening stud 1 near the lower end, through which the overall fastening connection combination is performed. An integrally formed position-limiting fitting reinforcement seat 3 is provided on the right side of the upper end of the main fastening stud 1, and a position-avoiding fitting inclined surface 4 is provided on the upper right end of the position-limiting fitting reinforcement seat 3, which can play a position-avoiding role during installation and use, ensuring a larger space on the right side. An arc-shaped position-limiting tight combination groove 5 with the same central axis as the central axis of the main fastening stud 1 is provided at the connection position between the lower end of the position-limiting fitting reinforcement seat 3 and the main fastening stud 1, which can be tightly combined with the structure of the fastening position below, so that the fitting position has a reliable anti-loosening effect. The connection position of the limiting tight combination groove 5 near the main body fastening stud 1 is provided with an integrally formed arc-shaped transition reinforcement and matching isolation column, which on the one hand improves the strength of the connection position, and on the other hand can have a certain isolation effect between the assembly position and the main body of the main body fastening stud 1, ensuring a larger matching space at the fastening position and a stronger overall combined force during fastening. The front of the limiting matching reinforcement seat 3 and the connection position of the main body fastening stud 1 are provided with a semi-cylindrical support matching positioning groove 6 with an upward opening, which can be matched with the upper end movable shaft to provide support for it. The interior of the support matching positioning groove 6 is provided with an arc-shaped lubrication matching safety groove 7 with the same central axis, which can be used with lubricating liquid to ensure better stability and safety of the movable shaft during use. When in use, it can be used as a fastening component to fasten mechanical parts, and at the same time can be tightly connected with surrounding components in a limited position. It can also cooperate with the movable shaft at the upper end position for support, and can provide it with a reinforced support function. The lubrication groove set at the matching position can ensure that the lubrication safety of the movable shaft during use is better, and the durability during use is stronger. This structure can replace the existing splicing of multiple components, is more convenient during installation and maintenance, has lower use costs, and has better structural stability at the assembly position during use.

[0021] Preferably, the width of the limiting and fitting reinforcement seat 3 in the front-to-back direction is the same as the diameter length of the main body fastening stud 1, so that the overall structural support strength is better, the service life during use is longer, and the overall flatness is better.

[0022] Preferably, the upper end surface of the main body fastening stud 1 and the upper end surface of the limit matching reinforcement seat 3 are on the same plane, so that the upper end position is more flat, more convenient during production and processing, and has a stronger bearing capacity during installation.

[0023] Preferably, the central axis of the support and fitting positioning groove 6 is located on the upper end surface of the position-limiting fitting reinforcement seat 3, so that the combination space at this position is larger during fitting and the stability during fitting is better.

[0024] Preferably, the lower end face of the limit fitting reinforcement seat 3 is an arc-shaped structural surface facing upward, which can play the role of avoiding and guiding fitting when the limit groove position is assembled, and at the same time can make the overall strength of this structure better and more durable during use.

[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.
