[0005] Furthermore, a mounting plate is symmetrically arranged on the traction seat, and the mounting plate is connected to the protective pad via a spring, and the protective pad is arranged corresponding to the push switch.
[0006] Furthermore, the number of the electric telescopic rods is , and the movable adjustment seat is rotatably arranged between two of the electric telescopic rods.
[0007] Furthermore, the supporting plate is fixedly provided with two vertical plates at intervals, and the fixed adjustment seat is rotatably provided between the two vertical plates through a rotating rod, and corresponding arc-shaped limit covers are provided on the four sides of the fixed adjustment seat and the movable adjustment seat, and the diameters of the movable adjustment seat on different sides of the movable adjustment seat and the fixed adjustment seat are different.

[0011] Further, the pre-cleaning mechanism includes a first linkage rod, a second linkage rod, a brush cylinder, a belt transmission structure, and a support frame, and a second linkage rod is arranged above the first linkage rod, and the first linkage rod is respectively connected to the second linkage rod and the transmission rod through the belt transmission structure, and the first linkage rod and the second linkage rod are both connected to the brush cylinder, and both ends of the first linkage rod and the second linkage rod are connected to the top of the bottom plate through the support frame; The support frame is provided with a through hole for the cable to pass through, and the through hole is arranged between the first linkage rod and the second linkage rod. Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention limits the position of the cable by using an electric telescopic rod, a movable adjustment seat and a fixed adjustment seat in coordination. The electric telescopic rod pushes the movable adjustment seat to drive the arc-shaped limit cover at the bottom of the movable adjustment seat to move downward to limit the cable inside the arc-shaped limit cover at the top of the fixed adjustment seat. At this time, the two groups of arc-shaped limit covers are surrounded in a cylindrical shape and fixed on the outside of the cable, that is, the inner wall of the arc-shaped limit cover contacts the outer wall of the cable, thereby expanding the contact area between the cable and the limit assembly, thereby improving stability while preventing it from causing pressure loss to the cable.
[0012] (2) The present invention can effectively solve the problem of the existing cable traction device being unable to actively end the limit after the cable is pulled to the specified position and having a low degree of automation by using a push switch. The motor drives the lead screw to rotate so that the traction seat drives the cable on its top to move. When the traction seat drives the cable to move to the specified position, the protective pad on its right side will squeeze and trigger the push switch. Then the controller will control the electric telescopic rod to move up and reset to end the limit, and at the same time control the motor to rotate in the opposite direction to reset the traction seat. When it is reset to the set position, the protective pad on the left side of the traction seat contacts the push switch on one side. Then the controller will control the electric telescopic rod to push the movable adjustment seat downward to limit the cable in the fixed adjustment seat, and control the motor to rotate to pull the cable, thereby improving the automation level of the device. (3) The staff can selectively use the corresponding arc-shaped limit cover by flipping the movable adjustment seat and the fixed adjustment seat, thereby facilitating the use of arc-shaped limit covers of different diameters to limit cables of different diameters, thereby improving the flexibility of the device structure; (4) The present invention can effectively solve the problem that the existing cable traction device is easily contaminated by pollutants carried by the waste cables when traction and winding them through the coordinated use of the pre-cleaning mechanism and the fan blade assembly. Under the transmission of the belt transmission structure, the first linkage rod and the second linkage rod drive the brush cylinder on one side to rotate synchronously with the lead screw, that is, the rotating brush cylinder is used to clean the cable to be towed, and thereby prevent it from causing pollution to the device during the subsequent traction process. At the same time, when the lead screw rotates, the fan blade assembly rotates synchronously to extract the external airflow, and the extracted airflow is discharged into the interior of the traction seat through the pipeline, and is sprayed onto the lead screw in the forward direction of the traction seat through the nozzle, that is, the lead screw is blown and dusted to ensure the normal traction of the traction seat.
