[0018] like Figures 1 to 5As shown, a convenient cable fastening and limiting sleeve comprises a cylindrical main body fastening column 1 made of metal material, a cylindrical fastening and matching connection hole 2 is provided at the center position of the upper end of the main body fastening column 1, and a fastening combination thread groove is provided inside the fastening and matching connection hole 2. When in use, multiple groups of cable cores are passed through this position, and then fastened and matched with the fastening combination column at the center position, so that the cores can be evenly distributed around the fastening combination column at the center position, and there is no need to directly wrap multiple cores, which ensures that the contact of the cores is more accurate during fastening. The outer side of the main body fastening column 1 is provided with an integrally formed insulating protective sleeve 3 by fusion, and the outer side of the insulating protective sleeve 3 completely wraps the outer side of the main body fastening column 1, so that the outer position has reliable insulation performance. The outer cylindrical surface of the insulating protective sleeve 3 is provided with arc-shaped hand-held operation matching grooves 4 evenly distributed around the circumference. When the overall fastening is performed, manual fastening operation is performed by holding this position, which is more convenient to operate. The upper and lower edge positions of the insulating protective sleeve 3 are provided with avoidance forming safety fillets 5, which play the role of avoidance, and the edge position is also easier to form when the molding mold is used for processing. The outer side of the main body limit fastening column 1 is connected to the connection position of the insulating protective sleeve 3 through a circumferentially staggered reinforced fusion matching structure to ensure that the fusion stability strength of the overall structure is more reliable. It adopts a brand-new structural design. The inner side is made of a metal structure that can cooperate with the cable core and can be fixed on the connecting column. The outer side is wrapped with an insulating protective layer to make the outer side safer, and it can be directly operated manually during tightening, which is more convenient to operate. The internal cable core matching position can realize the installation limit of the core, which is more flexible when used. It can replace the existing compression fastening accessories and occupies less space when used.
[0019] Preferably, the outer side of the main body limiting fastening column 1 is fused together with the insulating protection sleeve 3 through a boss, and the insulating protection sleeve 3 is processed by a mold forming production processing method, so that the coordination stability between the materials during the fusion processing is better and the overall structural strength is higher.
[0020] Preferably, an anti-skid safety operation groove is provided on the inner arc surface of the hand-held operation matching groove 4, which provides better stability during hand-held operation and more convenient tightening operation.
[0021] Preferably, an auxiliary positioning and matching column is provided on the upper end surface of the main body limiting and fastening column 1, which can be used as a positioning structure for installation and matching when other structural components on the upper end are matched later.
[0022] Preferably, the width of the hand-held operation matching groove 4 in the up-down direction is greater than the height of the insulating protective cover 3 in the up-down direction, so that the operation area during hand-held operation is larger and the matching stability during tightening operation is better.
[0023] 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.
