Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a dust sticking roller, including a square rod 1, an extension sleeve 2, a grip rubber sleeve 3, a knob 4, a positioning plate 5, a positioning rod 6, a limiting mechanism 7, a sleeve 701, a clamping rod 702, a spring 703, a clamping sleeve 8, a dust sticking rubber cylinder 9, a protective shell 10 and a clamping plate 11. An extension sleeve 2 is sleeved on the outer wall of the square rod 1, and a grip rubber sleeve 3 is fixedly connected to the outer wall of the extension sleeve 2. And the upper inner wall of the side of the extension sleeve 2 is movably connected with a knob 4. A positioning plate 5 is fixedly installed at the upper end of the square rod 1. And positioning rods 6 are respectively fixed on the outer walls of both sides of the square rod 1 below the positioning plate 5. And a limiting mechanism 7 is installed on the outer walls of the positioning rods 6. A dust sticking rubber cylinder 9 is fixedly connected to the upper surface of the positioning plate 5. And a protective shell 10 is arranged outside the dust sticking rubber cylinder 9. And clamping plates 11 are respectively fixed on both end faces of the protective shell 10.

[0023] The square rod 1 and the extension sleeve 2 form a sliding structure, and the square rod 1 is in contact with the knob 4, and the knob 4 is threadedly connected to the extension sleeve 2, which is convenient for the user to rotate the knob 4, so that the knob 4 moves relative to the extension sleeve 2 and disengages from the square rod 1, thereby facilitating the user to move the extension sleeve 2 to adjust the height of the device, and facilitating the device to adapt to different environments for use.

[0024] The limiting mechanism 7 includes a sleeve 701, a clamping rod 702 and a spring 703. And the sleeve 701 is sleeved on the outer wall of the positioning rod 6. And a clamping rod 702 is fixedly connected to the upper surface of the sleeve 701, which is convenient to limit the protective shell 10 through the limiting mechanism 7, so that the protective shell 10 is stably installed outside the dust sticking rubber cylinder 9, thereby providing sufficient protection for the dust sticking rubber cylinder 9.

[0025] The sleeve 701 and the positioning rod 6 are slidably arranged, and the inner wall of the end of the sleeve 701 is connected to the end face of the positioning rod 6 through a spring 703, which is convenient to elastically support the sleeve 701 through the spring 703 and facilitate the sleeve 701 to slide relative to the positioning rod 6.

[0026] A clamping sleeve 8 is fixedly connected to the lower surface of the positioning plate 5 on the side of the clamping rod 702. And both the clamping sleeve 8 and the clamping plate 11 are slidably connected to the clamping rod 702, which is convenient for the clamping rod 702 to slide relative to the clamping sleeve 8 when the sleeve 701 moves, so that the clamping rod 702 disengages from the clamping plate 11, thereby facilitating the user to move and open the protective shell 10.

[0027] The protective shell 10 and the positioning plate 5 are arranged in a fitting manner, and the positioning plate 5 and the clamping plate 11 are arranged in a sliding manner, which facilitates the user to move the protective shell 10 to disassemble and assemble the protective shell 10. When the protective shell 10 is moved, the clamping plate 11 slides relative to the positioning plate 5.

[0028] Working principle: When using this dust sticking roller, first, as Figures 1-5 shown, the user adjusts the height of the device according to the needs. At this time, the user rotates the knob 4, and then the knob 4 moves relative to the extension sleeve 2 and disengages from the square rod 1. Next, the user pushes the extension sleeve 2 to move along the square rod 1 to adjust the height of the device. When the device is adjusted to the appropriate height, the user rotates the knob 4 in the reverse direction, and then the knob 4 moves to fit with the square rod 1, thereby limiting the extension sleeve 2. Then, the user holds the grip rubber sleeve 3 and moves the dust sticking rubber cylinder 9 to fit with the object. Next, the user moves the device so that the dust sticking rubber cylinder 9 moves while fitting with the object, thereby sticking away the pollutants on the surface of the object and completing the cleaning of the object. Then, when the device is used up, the user pinches the sleeve 701 and moves it in opposite directions. At this time, the sleeve 701 slides along the positioning rod 6. Then, the sleeve 701 compresses the spring 703 to deform, and the sleeve 701 drives the clamping rod 702 to slide relative to the clamping sleeve 8. Next, the user moves the protective shell 10 so that the protective shell 10 drives the clamping plate 11 to insert into the positioning plate 5. Then, the user moves the protective shell 10 to fit with the positioning plate 5 and releases the sleeve 701. Then, the spring 703 resets and pushes the sleeve 701 to move. Next, the sleeve 701 drives the clamping rod 702 to move so that the clamping rod 702 inserts into the clamping plate 11, thereby completing the limitation of the protective shell 10. At this time, the protective shell 10 is stably positioned outside the dust sticking rubber cylinder 9, so that the protective shell 10 provides sufficient protection for the dust sticking rubber cylinder 9. Therefore, the device strengthens the protection of the dust sticking rubber cylinder 9 and avoids the accumulation of impurities on the dust sticking rubber cylinder 9 when the device is not in use, which affects the normal use of the device.
