When used as a transmission component, the matching force during rotation is relatively small, and the bearing capacity during use is not small. The durability during use is relatively poor, and the end is usually a planar structure. During rotation, the end position and the activity in the matching hole cannot be effectively lubricated.

[0020] like Figures 1 to 7The figure shows a set-type transmission rod. It includes a stainless steel rod main structure 1 with a central axis extending horizontally. An integrally formed cylindrical combination connecting column 2 is provided on the left side of the rod main structure 1. This serves as the main structure for interlaced assembly with the outer sleeve assembly during later installation. An integrally formed cylindrical stabilizing support column 3 is provided on the left side of the combination connecting column 2, ensuring greater structural strength at the end. A mounting hole is provided at the center of the left end face of the stabilizing support column 3, allowing for a secure connection as needed. Lubricating safety grooves 4, evenly distributed around the circumference and extending completely through the entire interior and exterior, are provided on the left end face of the stabilizing support column 3, ensuring greater space on the left side for lubricant during use. The combination connecting column 2 is also provided with U-shaped, right-facing, combination limiting grooves 5, evenly distributed around the circumference. When combined with a sleeve-like component, the column can be stably assembled with the structure at the mating position through interlaced insertion, improving overall structural stability during later rotation. The connection position between the combined connecting column 2 and the stable supporting connecting column 3 is provided with a heat-insulating safety matching groove 6 evenly distributed on the left and right and with the same central axis, which has reliable heat dissipation and heat insulation during use. It can set the associated matching structure at one end of the rod during installation, and the combination stability during the sleeve matching is improved. The setting of the limit matching groove can enable staggered combination with the rotating component during installation, resulting in stronger force and greater bearing capacity during rotation and higher safety during use. Its end is provided with a lubricating matching safety groove, which can be lubricated with lubricating liquid during the overall rotation process, making the end position more wear-resistant when matching and the overall rotation smoothness during use more reliable.

[0021] Preferably, the cross-section of the lubrication matching safety groove 4 is an arc-shaped structure, which provides better matching smoothness during the matching of the lubricating liquid, a larger lubrication contact matching area, and higher wear resistance at the end position.

[0022] Preferably, the cross-section of the heat-insulating safety fitting groove 6 is an arc-shaped structure, and the width of the inner side of the heat-insulating safety fitting groove 6 is greater than the width of the outer side. It can have a reliable heat-insulating effect when used and is also easier to produce and process.

[0023] Preferably, the inner side of the combined limiting fitting groove 5 close to the central axis of the combined connection fitting column 2 is a cylindrical structural surface, which makes the structural area at this position larger, improves the fitting stability during staggered combination, and further improves the bearing strength during rotation.

[0024] Preferably, the projections of the lubricating fitting safety groove 4 and the combined limiting fitting groove 5 in the left and right directions intersect, so that the strength of the main structure is better and the durability during use is more reliable.

[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.
