When in use, this structure can use the wire outlet groove 5 and the rubber pad 6, so that the lines connected to the motor controller body 16 can be used in a collected state, thereby reducing the situation where the lines are confused due to too many lines.

[0023] Furthermore, the limiting assembly includes a slot 9, a slot 9 is provided in the middle of the interior of the fixed tube 8, and a spring 10 is provided in the middle of the inner wall of the slot 9, an insertion rod 11 is inserted in the middle of the interior of the fixed tube 8, and the outer wall of the insertion rod 11 abuts against the outer wall end of the spring 10, a pull block 12 is fixedly connected to the outer wall end of the insertion rod 11, and the outer wall of the bracket 1 is adapted to the outer wall surface of the insertion rod 11. This structure can be rebounded by the spring 10 on the inner wall of the slot 9, so that the insertion rod 11 can return to its initial position by the rebound force of the spring 10 when it moves horizontally.
