[0025] In this example, the fixing mechanism 10 and the fixing mechanism 2 11 both include an insert block 15, which is symmetrically arranged on both sides of the guide rod 13 in the chamber, and the insert block 15 is adapted to the extrusion block 14, and the relatively outer end of the insert block 15 passes through the brush shaft 15 and is inserted into a slot symmetrically opened on the inner wall of the vertical brush cylinder 8. The guide rod 13 is symmetrically provided with a slide rod 16 on the relatively outer side, and the two ends of the slide rod 16 are respectively fixedly connected to the guide rod 13 and the inner wall of the chamber, and a stop block 17 and a spring 18 are sleeved on the outer side of the slide rod 16, and the spring 18 is located on the side away from the guide rod 13. Through the use of the fixing mechanism 10 and the fixing mechanism 2 11, it is convenient to disassemble the vertical brush cylinder 8 and the bristles 9, thereby facilitating the replacement of the bristles 9 in the deformation cycle or replacing the vertical brush cylinder 8 and the bristles 9 with new ones. It is easy to use and has strong practicality. In this example, the lower end of the bidirectional screw 12 in the fixing mechanism 11 is connected to a handle 1 outside the brush shaft 7, a transmission cavity is opened inside the upper end of the brush shaft 5, and the upper end of the bidirectional screw 12 in the fixing mechanism 10 is connected to a bevel gear 19 in the transmission cavity.

In this example, the anti-touch component includes a connecting sleeve 22, and the connecting sleeve 22 is arranged on the outside of the rotating rod 20 of the outer wall of the brush shaft 1 5, and the connecting sleeve 22 is adapted to both the handle 2 and the handle 1, and a fixing cover 23 is sleeved on the outer side of the connecting sleeve 22, and a fixing block 24 is symmetrically arranged on the inner wall of the opening end of the fixing cover 23, and a rail groove 29 adapted to the fixing block 24 is symmetrically arranged on the outer wall of the connecting sleeve 22, and a limiting groove 30 connected to the rail groove 29 is symmetrically arranged on the outer wall of the connecting sleeve 22, and the limiting groove 30 is adapted to the fixing block 24, and the fixing A baffle 25 is provided on one side of the handle 2 in the cover 23, and a slider 26 is symmetrically provided on the outer wall of the baffle 25.

The two ends of the spring 28 are respectively fixedly connected to the baffle 25 and the fixed cover 23 to guide and limit the fixed block 24.

[0026] The working principle of the utility model is as follows: when the car is about to be washed sideways, the rotating motor 4 is started to drive the brush shaft 1 5, the universal joint 6 and the brush shaft 2 7 to rotate, thereby driving the vertical brush barrel 8 and the bristles 9 to rotate. When the front of the car reaches the vertical brush, the traveling motor 2 drives the moving clamping plate 1 to move laterally inward, thereby driving the two vertical brush barrels 8 to lean against the car body. For the car body and the side window have an inclination angle, the traveling motor 1 drives the brush shaft 1 5 and the brush shaft 2 7 to continue to deviate toward the car body. Under the action of the car body, the brush shaft 1 5 and the vertical brush barrel 8 on its outer side will tilt, and the inclination angle is close to the side window glass. The brush shaft 2 7 and the vertical brush barrel 8 on its outer side will tilt due to their own weight. Due to the force factor, the tilt angle is small. At this time, the vertical brush barrel 8 on the brush shaft 1 5 and the brush shaft 2 7 forms an inclination angle closest to the angle of the car body, so as to adapt to the side of the car body, so as to better clean it. For MPV or wool van models, there is no inclination between the body and the side window. When the vertical brush approaches, the brush shaft 1 5 and the vertical brush barrel 8 on its outer side will not be driven to tilt. Under the action of its own gravity, the entire vertical brush is still cylindrical and can clean the car body normally. After long-term use, when some bristles 9 are deformed, the fixing cover 23 can be pushed to drive the fixing block 24 to slide in the track groove 29 to the limit groove 30, and then twist the fixing cover 23 to fix it. After the cover 23 drives the fixing block 24 to move to the position corresponding to the opening of the limiting groove 30, the force applied to the fixing cover 23 can be gradually released, so that the fixing cover 23 will reset and move under the elastic force of the spring 28, so that it drives the fixing block 24 to move out of the limiting groove 30, and releases the wrapping of the handle 1 and the handle 2. Then, the handle 1 is twisted to drive the bidirectional screw 12 in the fixing mechanism 2 11 to rotate, so that the bidirectional screw 12 drives the two extruding blocks 14 to move relatively outward. At the same time, the stopper 17 will drive the plug block 15 to reset and move relatively inward under the elastic force of the spring 18, so that the end of the plug block 15 inserted into the slot moves out, and the brush shaft 2 7 is released. The connection of the vertical brush cylinder 8 is fixed, and then the vertical brush cylinder 8 on the outside of the brush shaft 2 7 can be removed from the lower end of the brush shaft 2 7, and then the handle 2 is twisted to drive the rotating rod 20 to rotate, and then the bevel gear 21 drives the meshing bevel gear 19 to rotate, so that the bevel gear 19 drives the bidirectional screw 12 in the fixing mechanism 10 to rotate, and then the above steps of disassembling the vertical brush cylinder 8 on the outside of the brush shaft 2 7 are repeated to separate the connection between the brush shaft 1 5 and the vertical brush cylinder 8, and the vertical brush cylinder 8 can be pulled down to pass through the universal joint 6 and the brush shaft 2 7, so as to remove it, so as to replace the deformed bristles 9 or replace the vertical brush cylinder 8 and bristles 9 with new ones for use;When installing the vertical brush barrel 8, it is only necessary to sleeve the vertical brush barrel 8 on the outside of the brush shaft 1 5 and the brush shaft 2 7, repeat the above disassembly steps, drive the extrusion block 14 to move relatively inward, so that it squeezes the insertion blocks 15 on both sides to move relatively outward, so that one end of the insertion block 15 can be inserted into the corresponding slot. When installing the vertical brush barrel 8, first fix the vertical brush barrel 8 on the outside of the brush shaft 1 5 and then fix the vertical brush barrel 8 on the outside of the brush shaft 2 7, then set the fixing cover 23 on the outside of the connecting sleeve 22, insert the fixing block 24 into the limiting groove 30, and push the limiting groove 30 to make the turntable 27 fit with the handle 1 or the handle 2. Pushing the fixed cover 23 will move the fixed block 24 to the corresponding position where the rail groove 29 and the limit groove 30 are connected. The fixed cover 23 will be twisted, and the fixed cover 23 will drive the baffle 25 to rotate through the slider 26. At the same time, the fixed cover 23 will drive the fixed block 24 to move into the rail groove 29, releasing the thrust on the fixed cover 23, so that the fixed cover 23 is reset under the elastic force of the spring 28, and the fixed block 24 is moved to fit the side wall of the rail groove 29 away from the brush shaft 1 5, and the installation of the fixed cover 23 can be completed, so as to wrap and protect the handle 1 and the handle 2, and avoid accidental touch to affect the fixing effect of the opposing brush cylinder 8, which is convenient to use and more practical. ;

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
