The arm assemblies 2 are parallel to the radial direction of the annular structure 1, and one end of the arm assemblies 2 is located outside the annular structure 1 and is installed with a roller assembly 3. The moving direction of the roller assembly 3 is parallel to the axial direction of the first electric telescopic rod 5. Specifically, before use, the cable can be clamped and fixed on the annular structure 1 by using the clamping assembly 4; when in use, the two annular structures 1 can be placed in the pipe 13 in turn, so that the first electric telescopic rod 5 is parallel to the length direction of the pipe 13, and the roller assemblies 3 are respectively against the inner wall of the pipe 13.

[0026] In addition, symmetrically arranged second electric telescopic rods 6 are installed on both sides of each annular structure 1. The second electric telescopic rods 6 are parallel to the radial direction of the annular structure 1, and the end of the second electric telescopic rod 6 away from the annular structure 1 is the telescopic end and is located outside the annular structure 1. The telescopic ends of the second electric telescopic rods 6 are installed with tightening blocks 7. Specifically, the second electric telescopic rods 6 can be set as small electric push rods, and in the initial state, the telescopic ends of the second electric telescopic rods 6 are in a retracted state. When in use, when both annular structures 1 are located in the pipe 13, after the second electric telescopic rod 6 on the annular structure 1 located at the rear position is extended, the tightening block 7 can be pressed against the inner wall of the pipe 13 to fix the annular structure 1 located at the rear position in the pipe 13. At this time, after the first electric telescopic rod 6 is extended, the annular structure 1 located at the rear position can be fixed in the pipe 13. After the telescopic end of the retracting rod 5 is extended, the annular structure 1 located at the front position can be driven to move forward along the length direction of the pipe 13. When it is in place, the second electric telescopic rod 6 on the annular structure 1 located at the front position is extended, and the annular structure 1 located at the front position is fixed in the pipe 13 by the tightening block 7. Then, when the second electric telescopic rod 6 on the annular structure 1 located at the rear position is retracted, when the telescopic end of the first electric telescopic rod 5 is retracted, the annular structure 1 located at the rear position can be driven to move forward along the length direction of the pipe 13. In this way, the two annular structures 1 can be moved alternately in the pipe 13 in sequence, so that the cable can be driven to pass through the pipe 13; that is, the utility model can be applied to threading operations in pipes 13 whose outer walls are not exposed.

[0027] The specific configuration of the clamping assembly 4 is as follows: Figure 1As shown, the clamping assembly 4 includes a clamping tube 41 with openings at both ends and installed on the annular structure 1, and a third locking screw 42 is threadedly connected to the clamping tube 41. The third locking screw 42 is parallel to the radial direction of the clamping tube 41 and penetrates the clamping tube 41, and the end of the third locking screw 42 located outside the clamping tube 41 is provided with a third hand wheel 43, and the third hand wheel 43 can facilitate the rotation of the third locking screw 42; and when in use, after the cable is inserted into the clamping tube 41, the third locking screw 42 is rotated until the end of the third locking screw 42 away from the third hand wheel 43 is pressed against the cable, so that the cable can be clamped and fixed on the annular structure 1.

[0028] Further, such as Figure 1 As shown, there are multiple groups of clamping components 4, so that when in use, multiple cables can be clamped and fixed on the annular structure 1, thereby driving multiple cables to perform threading operations at the same time.

A first locking screw 23 is arranged between the movable rod 22 and the sleeve 21. The first locking screw 23 is threadedly connected to the sleeve 21 and passes through the sleeve 21, and one end of the first locking screw 23 abuts against the movable rod 22. The end of the first locking screw 23 outside the sleeve 21 is sleeved with a first hand wheel 24. A hand wheel 24 can facilitate the rotation of the first locking screw 23; specifically, during use, when the end of the first locking screw 23 away from the first hand wheel 24 is away from the movable rod 22, the movable rod 22 can be slid along the sleeve 21 to adjust the length of the arm assembly 2, so that the roller assembly 3 can be abutted against the inner wall of the pipe 13 with different inner diameters, and then the first locking screw 23 is rotated until the end of the first locking screw 23 away from the first hand wheel 24 is tightly abutted against the movable rod 22, the position of the movable rod 22 can be fixed on the sleeve 21, so as to be suitable for threading operations in pipes 13 with different inner diameters.

[0030] Furthermore, the movable rod 22 is a rectangular rod, and the sleeve 21 is a rectangular tube, so that when the position of the movable rod 22 is adjusted, the movable rod 22 will not rotate, thereby preventing the walking direction of the roller assembly 3 from changing.

[0031] Further, such as Figure 1 and Figure 2 As shown, the movable rod 22 is marked with a plurality of equally spaced scale lines 25 along the length direction of the movable rod 22 . By setting the scale lines 25 , each group of arm assemblies 2 can be easily adjusted to the same length.

[0033] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, each annular structure 1 is fixedly connected with a connecting plate 8 which is radially parallel to the annular structure 1, and both ends of the first electric telescopic rod 5 are respectively connected to the connecting plate 8, and both sides of the first electric telescopic rod 5 are provided with telescopic rods 9 which are arranged parallel to the first electric telescopic rod 5, and both ends of the telescopic rod 9 are respectively connected to the annular structure 1. Specifically, the telescopic rod 9 can be synchronously extended and retracted under the drive of the first electric telescopic rod 5; and by providing the telescopic rod 9, the connection strength between the two annular structures 1 can be improved to improve the stability of the threading device.

[0034] The specific configuration of the roller assembly 3 is as follows: Figure 1 , Figure 3 and Figure 4 As shown, the roller assembly 3 includes a U-shaped frame 31 installed on the arm assembly 2 and with the U-shaped opening facing outward, and a roller 32 is rotatably connected inside the U-shaped frame 31. The moving direction of the roller 32 is parallel to the axial direction of the first electric telescopic rod 5, and the outer periphery of the roller 32 is located outside the U-shaped frame 31. Specifically, when in use, when the outer periphery of the roller 32 abuts against the inner wall of the pipe 13, the annular structure 1 can be driven by the first electric telescopic rod 5 to move in the pipe 13 along the length direction of the pipe 13.

[0035] Further, such as Figure 1 As shown, each annular structure 1 is equipped with an electric control device 10, and the electric control device 10 includes a power supply and a PLC controller, etc.; one group of the electric control devices 10 is electrically connected to the first electric telescopic rod 5, and the electric control devices 10 located on the same annular structure 1 are electrically connected to the second electric telescopic rod 6 respectively.
