[0002] A cable is usually a cable similar to a rope formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a center to connect circuits, electrical appliances, etc. The whole is wrapped with a highly insulating covering layer and is widely used in the fields of mechanical equipment electricity, aerial conduction, underground signal transmission, etc. During the use of the cable, it is necessary to ensure the fixation and protection of the cable, so as not to be affected by the natural environment and electrical vibrations, etc., so that the machine can operate safely and reliably.

[0003] For example, in a Chinese patent with the publication number CN209626924U and the name of "A Quick Fixing Device for Cables", it includes an upper fixing clip and a lower fixing clip. The space between the upper fixing clip and the lower fixing clip is a through hole through which the cable can pass. The characteristics are as follows: One side of the upper fixing clip is hinged to one side of the lower fixing clip. On the other side of the upper fixing clip, there is an upper connecting piece extending downward. At the lower end of the upper connecting piece, there is an elastic buckle. At the upper end of the other side of the lower fixing clip, there is a lower connecting piece. At least two card slots are arranged in the height direction of the lower connecting piece, and the elastic buckle can just be stuck in the card slot.

[0004] Although the quick fixing device for a cable in the above patent is practical and convenient, it also has deficiencies. The above patent can only be adapted to a cable with one diameter. Therefore, when installing workers fix cables of different sizes, they need to customize different upper fixing clips and lower fixing clips, which is costly and affects the cable installation efficiency.

Both the arc-shaped rack and the arc-shaped block are arc-shaped, and the inner diameter and outer diameter of the arc-shaped block are smaller than those of the arc-shaped rack. A transmission component is arranged in the housing.

[0007] Further, the transmission component includes a first gear and two second gears. A first rotating shaft is arranged at the center of the first gear.

[0019] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please refer to Figures 1-4 , a technical solution provided by an embodiment of the present utility model: a quick fixing device for cable installation, including a housing 1, a through hole 2 for placing a cable is opened on the housing 1, the cross section of the through hole 2 is in an Ω shape, a groove 14 is opened in the housing 1, an arc-shaped rack 8 is circumferentially slidably connected in the groove 14, an arc-shaped block 11 is detachably connected to the inner wall of the arc-shaped rack 8, both the arc-shaped rack 8 and the arc-shaped block 11 are arc-shaped, and the inner diameter and outer diameter of the arc-shaped block 11 are both smaller than those of the arc-shaped rack 8. A transmission component is provided in the housing 1. By the cooperation between the arc-shaped rack 8 circumferentially slidably connected in the housing 1 and the inner wall of the through hole 2, the cable is clamped to achieve quick fixing of the cable. According to cables of different sizes, an arc-shaped block 11 can be installed on the inner wall of the arc-shaped rack 8 to adapt to the installation and fixing of cables with different diameters.

[0021] As a preferred technical solution, the transmission component includes a first gear 5 and two second gears 6. A first rotating shaft 4 is provided at the center of the first gear 5, and the first rotating shaft 4 is rotatably connected to the housing 1. Both second gears 6 are meshed with the first gear 5 and the arc-shaped rack 8. Specifically, two second rotating shafts 7 are symmetrically provided in the housing 1, and the two second gears 6 are rotatably connected to the two second rotating shafts 7 in a one-to-one correspondence. By providing two second gears 6, during the rotation of the arc-shaped rack 8, it is always meshed with at least one second gear 6, which not only plays a locking role but also prevents the arc-shaped rack 8 from shaking in the housing 1, reducing the installation and fixing efficiency.

[0022] As a preferred technical solution, a crank 3 is fixedly connected to one end of the first rotating shaft 4, and the first gear 5 is driven to rotate by rotating the crank 3, which is more labor-saving.

[0023] As a preferred technical solution, a slider 9 is provided at the bottom of the arc-shaped rack 8, and the slider 9 is arc-shaped. A sliding groove is opened in the groove 14, and the slider 9 is slidably connected to the sliding groove. Specifically, the sliding groove is arc-shaped, and the sliding groove plays a role of limiting and guiding, preventing the arc-shaped rack 8 from shaking and enabling the arc-shaped rack 8 to perform a circular motion along the sliding groove.

[0024] As a preferred technical solution, a first card slot 10 is opened on the inner wall of the arc-shaped rack 8, and a card block 12 is provided on one side of the arc-shaped block 11 close to the arc-shaped rack 8.
