Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 —9: A lint remover for easy replacement of paper tubes, comprising a support frame 11 and a handle 10, wherein a paper tube 14 is mounted on the support frame 11, wherein support plates 13 are provided on both sides of the support frame 11 to support the rotation of the paper tube 14, and the support plates 13 are provided with guide grooves 15 for easy replacement of the paper tube 14, and clamping rods 16 are provided inside the support frame 11, respectively located in the support plates 13 on both sides, wherein the inner side of the end of the clamping rod 16 is provided with a convex shaft 18 for locking and supporting the rotation of the paper tube 14, and at least one groove 20 is provided on the outer side of the end of the clamping rod 16, wherein a return spring A21 is provided in the groove 20. The end of the clamping rod 16 is locked by a convex shaft 18 and supports the rotation of the paper tube 14. The clamping rod 16 is L-shaped, and a rotating pin 19 is provided at the corner of the L. The clamping rod 16 is fixed in the support frame 11 by the rotating pin 19 and swings with the rotating pin 19 as the fulcrum. A transmission rod 17 is provided at the tail of the clamping rod 16. The transmission rod 17 is T-shaped and extends into the handle 10. A push button 12 is provided on the handle 10 to drive the transmission rod 17 to move. The transmission rod 17 presses the tail of the clamping rod 16, causing the clamping rod 16 to open and separate from both ends of the paper tube 14.

[0026] like Figure 3 As shown, the guide groove 15 has a trumpet-shaped opening facing the lateral direction of the support plate 13, which facilitates quick alignment with the installation position when installing a new paper tube and allows it to quickly enter the installation position along the guide groove 15. The convex shaft 18 passes through the inner side of the support plate 13 and is located at the bottom of the guide groove 15. Under the elastic force of the return spring A21, the convex shaft 18 is exposed at the bottom of the guide groove 15, so that the clamping rod 16 has a stable clamping force.

[0027] like Figure 8 and 9 As shown, in order to facilitate fixing and clamping the paper tube 14, wheel covers 24 are provided at both ends of the paper tube 14. A groove 25 is provided at the center of the outer side of the wheel cover 24. The groove 25 can slide along the guide groove 15 and engage with the convex shaft 18 to overcome the clamping force of the clamping rod 16. The convex shaft 18 can enter the groove 25, so that the paper tube 14 is clamped more firmly and stably, without affecting the rolling of the paper tube, and it is not easy to fall off.

[0028] like Figure 4 As shown, in order to ensure that the new paper tube can be smoothly locked with the convex shaft 18 on the clamping rod 16, the end face of the convex shaft 18 is provided with a bevel 22, and the bevel 22 faces the opening of the guide groove 15. When installing the new paper tube, the convex grooves 25 on the wheel covers 24 at both ends of the paper tube 14 can squeeze the bevel 22 on the convex shaft 18, causing the convex shaft 18 to retract into the support plate 13. After the paper tube 14 enters the fixed position, the clamping rod 16 rebounds under the action of the return spring A21, and the convex shaft 18 enters the convex groove 25 of the wheel cover 24, locking the paper tube 14.

[0029] like Figure 4 As shown, the inside of the convex shaft 18 is a cavity, and the return spring A21 is installed inside the cavity of the convex shaft 18 to prevent the return spring A21 from sliding. In order to adjust the clamping force of the clamping rod 16, the return spring A21 can also be installed in the groove 20, which is close to the rotating pin 19, so that the clamping force of the clamping rod 16 can be made gentler.

[0030] like Figure 4 As shown, in order to allow the clamping rod 16 to have sufficient swing space within the support plate 13, the body of the clamping rod 16 is wedge-shaped, and the thickness gradually increases from the end to the rotating pin 19.

[0031] like Figure 4 and 6 As shown, the T-shaped tail of the transmission rod 17 is hollow, and a return spring B23 is installed inside. One end of the return spring B23 acts on the transmission rod 17, and the other end acts on the inner wall of the support frame 11, so as to facilitate the rapid reset of the transmission rod 17.

[0032] like Figure 1 As shown, the support frame 11 is provided with a protective cover 26 to cover the paper tube 14. When not in use, this prevents debris from sticking to the paper tube. When in use, the protective cover 26 can be removed.

[0033] Working principle: When the paper tube 14 needs to be replaced, push the push button 12 on the handle 10 to overcome the rebound force of the return spring B23. The push button 12 drives the transmission rod 17 to move. The transmission rod 17 squeezes the tail of the clamping rod 16, causing the clamping rod 16 to rotate around the rotating pin 19. The convex shaft 18 at the end of the clamping rod 16 retracts into the support plate 13 and separates from the wheel covers 24 at both ends of the paper tube 14. Then the paper tube 14 can be taken out along the guide groove 15.

[0034] When reinstalling the new paper tube 14, slide the paper tube 14 down along the guide groove 15. The protrusion 25 of the wheel cover 24 begins to press against the inclined surface 22 of the convex shaft 18, causing the convex shaft 18 to retract until the paper tube 14 is fully in the fixed position. Under the restoring force of the return spring A21, the convex shaft 18 is fully inserted into the protrusion 25, clamping the paper tube 14. Installing and removing the paper tube is convenient, quick, and saves time and effort.

[0035] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
