The end surfaces of one side of the first arc-shaped plate 44, which is opposite to the second arc-shaped plate 45, and the bottom end surfaces of the first arc-shaped plate 44 and the second arc-shaped plate 45 are cambered surfaces;
When the round rod 33 drives the rotating wheel 35 to rotate in the groove body 13, the driven plate 41 drives the first arc-shaped plate 44 and the second arc-shaped plate 45 to move in the groove body 13, and the bottom of the groove body 13 can be scratched in the process that the first arc-shaped plate 44 and the second arc-shaped plate 45 move in the groove body 13, so that impurities at the bottom of the groove body 13 can be pushed to move, and the effect of crack filling due to the impurities is avoided;
Specifically, when the rotating wheels 35 gradually move down to the groove body 13, the rotating wheels 35 approach each other, the driven plates 41 are driven to approach each other by the annular sheets 36, and the driven plates 41 drive the first arc plates 44 and the second arc plates 45 to approach each other, and the first arc plates 44 and the second arc plates 45 are arranged in a staggered manner and are mutually attached, so that the first arc plates 44 and the second arc plates 45 can move to opposite sides and gradually overlap, and in the process, the first arc plates 44 and the second arc plates 45 overlap each other, so that the first arc plates 44 and the second arc plates 45 can adapt to the groove bodies 13 with different widths as the two rotating wheels 35, and the adaptability of the first arc plates 44 and the second arc plates 45 is improved;
More specifically, because the bottom end surfaces of the first arc plate 44 and the second arc plate 45 are cambered surfaces, when the bottom of the groove body 13 is scratched by the first arc plate 44 and the second arc plate 45 in the groove body 13, if the bottom of the groove body 13 is convex, the first arc plate 44 and the second arc plate 45 can move upwards after being subjected to convex resistance, and the second ball 46 can be driven to move upwards in the C-shaped groove 43 in the upward moving process of the first arc plate 44 and the second arc plate 45, so that the convex is avoided, and the first arc plate 44 and the second arc plate 45 are prevented from being damaged.
Embodiment four:
Two of the ring segments 36 are gear-shaped; a cleaning layer 421 is fixedly connected in each of the two grooves 42, and the cleaning layer 421 is made of rubber material; because the ring piece 36 is gear-shaped, when the ring piece 36 rotates in the groove body 13, the contact area between the ring piece 36 and the bottom of the groove body 13 can be reduced, so that the ring piece 36 which is penetrated by the bulge existing at the bottom of the groove body 13 is prevented from being jacked up, and when the ring piece 36 passes through the notch 42, the cleaning layer 421 pinched by the notch 42 can wipe the ring piece 36, so that the ring piece 36 is prevented from being adhered with impurities.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
