The stopper 66 is sleeved on the outer side of the sleeve 61 and is threadedly connected to the outer side wall of the sleeve 61. And the stopper 66 is located on the side of the stopper 651 away from the slide bar 62. Therefore, the stopper 651 slides to the side away from the slide bar 62.

[0038] Preferably, in this embodiment, there are multiple blocking rods 651 , and the multiple blocking rods 651 are evenly arranged on the outer side of the blocking piece 65 along the circumference of the blocking piece 65 .

[0039] In some embodiments, the swing frame 2 can be used as follows: Figure 1 See the structure shown. Figure 1 A pitching arm 7 for adjusting the height of the sweeping disc 3 is provided between the swing frame 2 and the sweeping disc 3. Both ends of the pitching arm 7 are respectively hinged on the swing frame 2 and the sweeping disc 3, and a pushing member 8 for driving the pitching arm 7 to swing is also provided between the swing frame 2 and the pitching arm 7. The axis of the hinge shaft of the swing frame 2 on the fixed arm 1 is arranged in the vertical direction, and the axis of the hinge shaft of the pitching arm 7 on the swing frame 2 is arranged in the horizontal direction. A pushing member 8 is installed on the swing frame 2, and the pushing member 8 is a cylinder or a hydraulic cylinder. When operation is required, the pushing member 8 can drive the pitching arm 7 to swing downward and make the sweeping disc 3 contact the ground. After the operation is completed, the sweeping disc 3 can be raised by the pushing member 8. The structure is simple and the operation is convenient.

[0040] Specifically, in this embodiment, a fixed frame is hingedly provided at one end of the pitch arm 7 away from the swing frame 2, an L-shaped plate is installed on one side of the fixed frame, one side wing plate of the L-shaped plate is fixedly installed on the fixed frame, and the other side wing plate is arranged in a horizontal direction, the sweeping disc 3 is installed at the bottom of the L-shaped plate, and a motor for driving the sweeping disc 3 to rotate is installed on the top of the L-shaped plate.

[0041] In some embodiments, the swing frame 2 can be used as follows: Figure 1 See the structure shown. Figure 1A balancing arm 9 is also provided between the swing frame 2 and the sweeping disc 3 and is arranged in parallel with the pitching arm 7. The two ends of the balancing arm 9 are respectively hinged on the swing frame 2 and the sweeping disc 3. A balancing arm 9 is also provided between the swing frame 2 and the sweeping disc 3. The balancing arm 9 is arranged in parallel with the pitching arm 7. The balancing arm 9 and the pitching arm 7 form a parallelogram in combination with the swing frame 2 and the sweeping disc 3. Thus, the sweeping disc 3 can be moved in the vertical direction, ensuring that the brush part at the bottom of the sweeping disc 3 is effectively attached to the ground.

[0042] Specifically, in this embodiment, when the sweeper is in the working state, the driving member 5 pushes the swing frame 2 to unfold the pitch arm 7, and the length direction of the pitch arm 7 is tilted outward away from the traveling direction of the vehicle, so that the pitch arm 7 can be pushed to swing toward the inside of the vehicle when it touches an obstacle.

Figure 1 The pusher 8 is located above the pitch arm 7, the fixed end of the pusher 8 is hinged on the swing frame 2, and the driving end of the pusher 8 is hinged in the middle of the pitch arm 7. The pusher 8 is located above the pitch arm 7. When the driving end of the pusher 8 is extended, the pitch rod can be driven to swing downward. When the driving end of the pusher 8 is retracted, the pitch rod can be driven to swing upward and retract the sweeping disc 3.

[0044] Specifically, in this embodiment, there are two pitching arms 7, which are arranged in parallel and spaced apart. A fixed shaft is connected to the middle of the two pitching arms 7, and the driving end of the pusher 8 is hingedly arranged on the fixed shaft. There are also two balancing arms 9, which are also arranged in parallel and spaced apart. This enhances the support strength of the sweeping disc 3.
