[0020] Such as Figures 1 to 7As shown in the figure, an active mechanical fastener includes a cylindrical main body fastening connection column 1. A cylindrical mating stop and stabilizing column 2 is integrally formed on the left side of the main body fastening connection column 1. A cylindrical combined positioning and mating hole 3 is provided at the center of the left end face of the mating stop and stabilizing column 2. During axial assembly, this structure can be used as a mating reference hole for assembly. During later use, it can be used as a rotation reference structure for rotational mating at this position, ensuring higher accuracy of the mating position. A sealing combined stabilizing groove 4 with a regular hexagon cross-section is provided on the left side of the combined positioning and mating hole 3, which can be used for mating and installing with a sealing component to ensure the sealing performance of the mating position. The use of a regular hexagon cross-section structure design can make the stability of the sealing mating position better, and the sealing structure will not rotate during rotation. A cylindrical rotational mating connection groove 5 with the same central axis is provided at the right side position of the outer cylindrical surface of the mating stop and stabilizing column 2. A cylindrical anti-loosening mating safety column 6 is integrally formed on the right side of the rotational mating connection groove 5. During installation, the end mating groove of the sleeve is inserted from this position. Lubricating paste or lubricating liquid is provided inside the rotational mating connection groove 5 for lubricating the rotation of the sleeve. Circumferentially evenly distributed lubricating and stabilizing mating grooves 7 are provided on the left side surface of the rotational mating connection groove 5, which can be used for reserving lubricating paste or lubricating liquid, ensuring better lubricating safety during later use. The cross-section of the lubricating and stabilizing mating groove 7 is an arc-shaped structure. A clearance safety mating groove 8 with the same size as the lubricating and stabilizing mating groove 7 and completely penetrating the anti-loosening mating safety column 6 in the left-right direction is provided on the right side of the anti-loosening mating safety column 6, ensuring more convenient processing of the lubricating and stabilizing mating groove 7. It can be directly processed from the right side for mating, avoiding the situation of difficult processing due to small space during die forming processing. Through the internally provided positioning and mating hole, during axial assembly, it can be inserted and mated with a rotating component, and can be used as a rotational reference hole during use to ensure the mutual accuracy during mating. On the outer side, through the provision of a rotational mating connection groove and a lubricating groove, it can be mated with the end of the sleeve. Through the provision of lubricating paste, it can ensure better lubricating effect of the sleeve end during use, and can pre-store lubricating paste, with stronger durability and higher safety during use.
[0021] Preferably, the depth of the sealing combined stabilizing groove 4 is greater than the thickness of the mating stop and stabilizing column 2, making the space at the sealing mating position larger and the mating stability better.
[0022] Preferably, the inner arc-shaped structural surface of the lubricating and stabilizing mating groove 7 coincides with the cylindrical surface of the rotational mating connection groove 5, making this structure more convenient for production and processing, with better flatness at the inner side position and better lubricating mating smoothness during use.
[0023] Preferably, the right side of the anti-loosening fitting safety post 6 is a conical structural surface, which plays a role of guiding fitting during fitting and ensures more convenient operation during assembly.
[0024] Preferably, anti-positioning safety chamfer structures are provided at the left side of the fitting stop stabilizing post 2 and at the right edge position of the main body fastening post 1, which improves the safety of the outer position and avoids the existence of sharp corner structures.
[0025] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or substitutions can be made, and these improvements or substitutions should also be regarded as the protection scope of the present invention.
