Detailed implementation manners

[0020] Such as Figures 1 to 7As shown in the figure, a stainless steel fastening and limiting protective sleeve includes a conical main body and a stable seat 1. An integrally formed cylindrical overall fastening connection column 2 is provided at the upper end of the main body and stable seat 1 for overall installation and cooperation. At the upper end of the overall fastening connection column 2, overall locking and fixing holes 3 are evenly distributed in a circumferential manner, and the overall structure and mechanical components can be firmly connected by cooperating with fastening screws. At the center position of the upper end of the overall fastening connection column 2, a conical assembly combination connection groove 4 is provided, which can be inserted and combined with the end of a shaft-like component and can cooperate with a cylindrical or conical end structure. At the center position of the lower end of the assembly combination connection groove 4, a cylindrical assembly avoidance and cooperation hole 5 penetrating the lower end face of the whole is provided, which can cooperate and avoid interference with the cooperation shaft or fastening component at the center position during assembly. On the front surface of the main body and stable seat 1, a limiting combination installation groove 6 with an opening to the right and completely penetrating the whole in the front-rear direction is provided, which can be combined and connected with the outer lateral structure. At the lower right front position of the limiting combination installation groove 6, an avoidance assembly convenient groove 7 penetrating the lower end of the whole is provided to ensure a larger space at the lower end position and make the cooperation operation at this position more convenient. On the upper end surface of the limiting combination installation groove 6, limiting anti-loosening clamping grooves 8 are evenly distributed in a circumferential manner. The projection of the limiting anti-loosening clamping grooves 8 in the up-down direction is located within the area of the avoidance assembly convenient groove 7. Only within this area can the smooth operation during assembly be guaranteed, otherwise the installation will be affected. When in use, the upper end position is tightly fitted with the mechanical component through locking, the center position can be inserted and combined with the end of the shaft-like structural component, the lower outer position can be inserted and combined with the outer mechanical component through a lateral cooperation structure, and the combination of the limiting anti-loosening structure can effectively guarantee the overall strength during the cooperation connection, with higher efficiency during installation and cooperation, more convenient operation during maintenance, higher connection strength at the overall installation position, stronger durability during use, and higher bearing capacity.

[0021] Preferably, a cooperation guiding rounded corner structure is provided at the lower end of the limiting anti-loosening clamping groove 8, which makes the combination fluency better during the clamping cooperation of the limiting structure, the convenience during cooperation stronger, the assembly combination efficiency higher, and precise alignment is not required.

[0022] Preferably, the depth of the limiting combination installation groove 6 is greater than half of the diameter length of the position where the main body and stable seat 1 are located, so that the structural cooperation space at the lateral combination position is larger and the combination connection strength is higher.

[0023] Preferably, the inner side surface of the avoidance assembly convenient groove 7 is in the same plane as the central axis of the main body and stable seat 1, so that the space at the avoidance position is relatively large, and at the same time, the structural strength at the lower end position can be guaranteed to be relatively reliable.

[0024] Preferably, the limiting combined installation groove 6 is located at a position slightly above the center in the up-and-down direction of the main body fitting stable seat 1, so that the structural combination strength during fitting at this position can be further improved, and the bearing capacity during fitting is stronger.
