[0018] like Figures 1 to 7As shown, an isolated type safety movable mating shaft comprises a cylindrical connecting shaft main body safety column 1, and the left and right center positions of the connecting shaft main body safety column 1 are respectively provided with an integral cylindrical assembly combination connecting column 2, and the center position of the assembly combination connecting column 2 on the right side is provided with an integral fastening connecting column 3, which can form the main structure of this product. An integral assembly fastening connection thread groove is provided on the outer cylindrical surface of the integral fastening connecting column 3, and when fastening and installing as a whole, the fastening assembly is directly performed through the thread groove, making the fitting operation during installation easier. An assembly guide fitting fillet 4 is provided at the outer edge position of the assembly combination connecting column 2, and the operation during the fitting installation at the outer position is more convenient. A first movable lubricating matching groove 5 and a second movable lubricating matching groove 6 are respectively provided between the left and right end faces of the two left and right assembly combined connecting columns 2 and the left and right end faces of the connecting shaft main body safety column 1. When in use, they can be matched with lubricating liquid and matched with the ends of the shaft structure that are inserted and matched at both ends, and matched as the movable matching structure of the shaft movable part. When in use, they can play a supporting and matching role, ensuring better smoothness of movement during use and more reliable rotation stability of the shaft parts. The cross-sections of the first movable lubricating matching groove 5 and the second movable lubricating matching groove 6 are both conical structures, which make the structural strength of both sides better and the matching area larger when the lubricating liquid is matched. When in use, it can be used as a shaft part for direct matching, and can also be used as an installation matching part of the shaft movable part for transition matching. It is more flexible when in use. It can be directly fastened and matched as a whole through the connecting column on one side during installation. The two sides of the main structure are respectively provided with movable lubricating matching grooves. When in use, it can be matched with lubricating liquid to achieve comprehensive lubrication of the shaft movable matching position, ensuring better matching smoothness during use, higher activity safety, and stronger durability when in use.

[0019] Preferably, the inner conical structural surfaces of the first movable lubrication matching groove 5 and the second movable lubrication matching groove 6 are provided with lubricating paste storage matching grooves evenly distributed around the circumference, which can be set with more lubricating paste when in use, ensuring a longer lubrication cycle during use, further improving lubrication safety, and making the movable matching position have a certain heat dissipation effect during use, thereby enhancing its durability during use.

[0020] Preferably, the outer edge of the integral fastening connection column 3 is provided with a chamfer structure for convenient installation and assembly, which makes the operation more convenient during fastening and installation.

[0021] 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.
