The two stopper rods 811 are coaxially arranged and located on both sides of the limit rod 81. When the end of the limit rod 81 is located inside the limit hole, the limit rod 81 drives the stopper rod 811 to slide into the open groove. The connection sleeve 51 and the rotating shaft 41 are fixed. When the stopper rod 811 is pulled outward and the limit rod 81 is rotated so that the stopper rod 811 abuts against the end of the mounting sleeve 52, when the stopper rod 811 abuts against the end of the mounting sleeve 52, the limit rod 81 is disengaged from the limit hole, thereby facilitating the rotation of the mounting plate 5. The structure is simple, and it is convenient to adjust the state of the control mounting plate 5 at the end of the connecting arm 4.

[0041] In some embodiments, the rotating shaft 41 may be Figure 3 See the structure shown.

Two limit holes are arranged on the outer side of the same rotating shaft 41, and the axes of the two limit holes are respectively arranged in the vertical direction and in the horizontal direction. When the mounting plate 5 is rotated on the connecting arm 4 until the axis of the sweeping disc 6 is arranged in the vertical direction, the end of the limit rod 81 slides into the inside of the limit hole arranged in the horizontal direction. When the mounting plate 5 is rotated until the axis of the sweeping disc 6 is arranged in the horizontal direction, the end of the limit rod 81 slides into the inside of the limit hole arranged in the vertical direction. It is convenient to adjust the position of the mounting plate 5 at the end of the connecting arm 4, and the operation is more convenient and quick.
