[0027] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] Reference Figure 1-Figure 3 As shown, the utility model provides a technical solution: a combined cable sheath, including a first sheath 1 and a second sheath 2, the cross-section of the first sheath 1 and the second sheath 2 is an arc-shaped structure, the front ends of the first sheath 1 and the second sheath 2 are fixedly connected with a fixing block 3 at the back, the rear ends of the first sheath 1 and the second sheath 2 are fixedly connected with a shell 4, both sides of the fixing block 3 are provided with a card slot 5, the cross-section of the card slot 5 is a rectangular structure, the side of the fixing block 3 close to the shell 4 is provided with a sliding groove 6, the shell A through groove 7 is provided on one side of the body 4 close to the fixed block 3, and first through holes 8 are provided on both sides of the shell 4. A card block 9 is inserted into the inner diameter of the card slot 5. The cross section of the card block 9 is trapezoidal. The surface of the card block 9 is adapted to the inner diameter of the card slot 5. The rear end of the card block 9 is fixedly connected to a transmission block 10, and the opposite back side of the transmission block 10 is fixedly connected to a control rod 11. The surface of the control rod 11 is slidably connected to the inner diameter of the first through hole 8, and the end of the control rod 11 away from the transmission block 10 is fixedly connected to a control block 12.

[0029] The following is a detailed description of the specific settings and functions of the connecting mechanism and the splicing mechanism.

[0030] Reference Figure 3As shown, in the present embodiment: the user drives the control rod 11 by pressing the control block 12, so that the control rod 11 drives the transmission block 10 to move, so that the clamping block 9 is disengaged from the inner diameter of the clamping slot 5, and the limiting effect on the fixing block 3 is released, so that the user can separate the multiple first sheaths 1, so as to repair the internal cables. When the repair is completed, the first sheath 1 is installed to the original position, and the control rod 11 is driven by the moving control block 12, so that the transmission block 10 drives the clamping block 9 to be inserted into the inside of the clamping slot 5, so as to complete the limiting of the fixing block 3, and continue to protect the cable. The position of the fixing block 3 is fixed by the plugging of the clamping block 9 and the clamping slot 5, so that the positions of the multiple first sheaths 1 are fixed. When the user needs to maintain and inspect the cable, the clamping block 9 is moved out of the inner diameter of the clamping slot 5 to quickly release the limiting effect on the first sheath 1, and the first sheath 1 that needs to be maintained is exposed by moving the first sheath 1. The first spring 15 is slidably connected to the surface of the first slide bar 13, so as to facilitate the maintenance and repair of the cable. A first slide bar 13 is installed inside the shell 4, and both sides of the first slide bar 13 are fixedly connected to both sides of the inner wall of the shell 4. A second through hole 14 is opened on the surface of the transmission block 10, and the inner diameter of the second through hole 14 is slidably connected to the surface of the first slide bar 13. When the transmission block 10 moves, the inner diameter of the second through hole 14 is slidably connected to the surface of the first slide bar 13, so that the transmission block 10 is more stable when moving, and the deviation of the transmission block 10 is reduced. The surface of the first slide bar 13 is slidably connected with a first spring 15, and both sides of the first spring 15 are fixedly connected to the facing surface of the transmission block 10. When the card block 9 is inserted into the inner diameter of the card slot 5, the position of the transmission block 10 is limited by the elastic force generated by the first spring 15. The first spring 15 prevents the transmission block 10 from driving the card block 9 out of the inner diameter of the card slot 5 due to external force, thereby ensuring the overall reliability of the device.

[0031] Reference Figure 4 and Figure 5As shown, in this embodiment: both sides of the first sheath 1 and the second sheath 2 are fixedly connected with a protrusion 16, the opposite back of the protrusion 16 is clamped with a limit block 17, the surface of the protrusion 16 is provided with a limit hole 18, the limit hole 18 is a circular structure, the top and bottom of the limit block 17 are provided with a third through hole 19, the limit block 17 is fixedly connected with a boss 20 on the side away from the first sheath 1 and the second sheath 2, the top and bottom of the boss 20 are fixedly connected with a second slide bar 21, the surface of the second slide bar 21 is slidably connected with a movable block 22, and the movable block 22 is close to the protrusion 16. The limiting column 23 is fixedly connected to the side, and the outer diameter of the limiting column 23 is the same as the inner diameter of the limiting hole 18. The surface of the limiting column 23 is plugged into the inner diameter of the limiting hole 18. The user drives the limiting column 23 to disengage from the inner diameter of the limiting hole 18 by moving the movable block 22, thereby releasing the limit of the limiting block 17. By removing the limiting block 17 from the surface of the protrusion 16, the limit of the first sheath 1 and the second sheath 2 is released, so that the user can separate the first sheath 1 and the second sheath 2. By placing the cable inside the first sheath 1 and the second sheath 2, the first sheath 1 and the second sheath 2 are released. The facing surfaces of the first and second sheaths 1 and 2 are fitted together, the limiting block 17 is clamped on the surface of the protrusion 16, and the limiting column 23 is driven by the movable block 22 to be inserted into the inner diameter of the limiting hole 18, so that the positions of the first and second sheaths 1 and 2 are fixed, so that it is convenient for users to quickly install the first and second sheaths 1 and 2, and it is convenient for users to quickly remove the first and second sheaths 1 and 2 to repair the damaged parts of the cable. The end of the second slide bar 21 away from the protrusion 20 is fixedly connected with a baffle 24, and the side of the baffle 24 close to the movable block 22 is in contact with the surface of the movable block 22. When the movable block 22 drives the limiting column 23 to move to the side away from the protrusion 16, the movable block 22 is limited by the baffle plate 24 to prevent the movable block 22 from being separated from the surface of the second slide bar 21. The side of the baffle plate 24 close to the movable block 22 is fixedly connected with a second spring 25, and the end of the second spring 25 away from the baffle plate 24 is fixedly connected to the surface of the movable block 22. When the limiting column 23 is inserted into the inner diameter of the limiting hole 18, the second spring 25 limits the position of the movable block 22 to prevent the limiting column 23 from being separated from the inner diameter of the limiting hole 18.

[0032] According to the working principle of the utility model, the user drives the control rod 11 by pressing the control block 12, so that the control rod 11 drives the transmission block 10 to move. When the transmission block 10 moves, the inner diameter of the second through hole 14 is slidably connected with the surface of the first slide rod 13, so that the transmission block 10 is more stable when moving, and the deviation of the transmission block 10 is reduced. The movement of the transmission block 10 disengages the card block 9 from the inner diameter of the card slot 5, and the limiting effect on the fixed block 3 is released, so that the user can separate the multiple first sheaths 1, thereby repairing the internal cables. When the repair is completed, the first sheath 1 is installed to the original position, and the control rod 11 is driven by the moving control block 12, so that the transmission block 10 drives the card block 9 to be inserted into the inside of the card slot 5. Thus, the limiting of the fixed block 3 is completed, and the position of the transmission block 10 is limited by the elastic force generated by the first spring 15. The first spring 15 prevents the transmission block 10 from driving the clamping block 9 to disengage from the inner diameter of the clamping slot 5 due to external force. The first sheath 1 and the second sheath 2 are fixed to continue to protect the cable. The position of the fixed block 3 is fixed by the connection between the clamping block 9 and the clamping slot 5, so that the positions of multiple first sheaths 1 are fixed. When the user needs to maintain and inspect the cable, the clamping block 9 is moved out of the inner diameter of the clamping slot 5 to quickly release the limiting of the first sheath 1. The first sheath 1 is moved to expose the part that needs maintenance, so that the cable can be maintained and inspected.
