The inner walls of the first electrical conduit 2 and the second electrical conduit 3 are provided with plastic films 13, and the plastic films 13 can effectively reduce the wear of the lines in the connector and make the passage of the lines more convenient.

[0019] A vertically arranged limit barrel 4 is provided in the second electrical conduit 3, and the limit barrel 4 is fixed to the bottom of the second electrical conduit 3. A movable rod 5 is provided in the limit barrel 4 along its length direction, and the movable rod 5 passes through the top of the limit barrel 4 and passes through the second electrical conduit 3 and the top of the embedded part 1. A hook 6 is provided at the top of the movable rod, and the movable rod 5 can move in the vertical direction. A spring 7 is sleeved on the movable rod 5, and the spring 7 is located in the limit barrel 4. The bottom end of the spring 7 is connected to the bottom end of the movable rod 5, and the top end is connected to the top of the limit barrel 4. The spring 7 can apply a downward elastic force to the movable rod 5. A pressing plate 8 with an arc-shaped structure is provided in the second electrical conduit 3, and the curvature of the pressing plate 8 is adapted to the curvature of the second electrical conduit 3. The pressing plate 5 is fixed on the movable rod 5 and can move in the vertical direction with the movable rod 5.
