[0028] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0029] In the present application, the base bracket 2 is a frame structure, which can be a "convex" type frame, and an adjustment foot 1 is connected at its corner position through a threaded structure. The adjustment foot 1 is placed on a horizontal plane or a workbench to adjust the levelness of the base bracket 2 to ensure the stability of the base bracket 2.

[0030] In the present application, a winding wheel 3 is mounted on the base bracket 2, and the winding wheel 3 includes a turntable and a shaft body on which the winding wheel can be placed, and the turntable is driven by a feeding motor assembly 14. The feeding motor assembly 14 includes a feeding motor, and the output end of the feeding motor is connected to a gearbox, and the output end of the gearbox is connected to a turntable and a shaft body.

[0031] The winding wheel 3 or the wire wheel placed on the winding wheel 3 is wound with a conductive wire 6.

[0032] The base support 2 is provided with a vertical support 11 in the wire feeding direction. The vertical support 11 is vertically arranged relative to the base support 2 and is fixedly connected to the base support 2 .

[0033] The vertical bracket 11 is composed of two rods or profiles.

The vertical bracket bottom plate 10 and the vertical bracket top plate 4 are arranged relatively parallel.

[0034] A matrix-arranged vertical support rod 7 is also connected between the vertical support top plate 4 and the vertical support bottom plate 10. Preferably, in the present application, the vertical support rod 7 is four bare rods, and the bottom guide wheel 9 slides along the vertical support rod 7 through the bottom wheel adjustment seat 8. The bottom guide wheel 9 moves along the vertical support rod 7 relative to the vertical support bottom plate 10 under the lifting of the wire 6. The bottom wheel adjustment seat 8 is also connected to a sensor pull rope 15, which is connected to a pull rope sensor 13, and the pull rope sensor 13 can be arranged on the bottom surface of the vertical support bottom plate 10.
