With the use of the locking teeth 122, the fixing component 5 is engaged with the output end of the drive motor 123, which facilitates the drive motor 123 to drive the fixing component 5 to rotate, thereby driving the take-up and unwinding roller 2 to rotate, realizing take-up and unwinding.

[0030] like Figures 4 to 5As shown, the telescopic assembly 3 includes a connecting shaft 33 located outside the take-up and release rollers 2. One end of the connecting shaft 33 extends into the interior of the stretching groove 21. A slider 31 is fixedly connected to the end of the connecting shaft 33 inside the stretching groove 21, and the slider 31 fits into the stretching groove 21. A tension spring 32 is connected to the other end of the slider 31, and the other end of the tension spring 32 is connected to the inner wall of the stretching groove 21. A limit block 34 is fixedly connected to the end of the connecting shaft 33 outside the stretching groove 21, and a limit shaft 34 is fixedly connected to the other end of the limit block 34. 6. The limiting shaft 36 extends into the through hole 41. A fixing component 5 is movably connected to one end of the limiting shaft 36 inside the through hole 41. The fixing component 5 extends into the inner cavity 124 and engages with the output end of the drive motor 123. A handle 35 is fixedly connected to the outer wall of the limiting block 34. A recessed fixing hole 363 is provided on the outer wall of the end of the limiting shaft 36 extending into the through hole 41. A rectangular groove 361 is provided inside the limiting shaft 36, communicating with the fixing hole 363. Multiple limiting positions are provided on the outer wall of the limiting shaft 36. Hole 362, the limiting hole 362 communicates with rectangular groove 361; the fixing component 5 includes a knob 51 extending into the inner cavity 124, the end of the knob 51 near the limiting shaft 36 is fixedly connected to a fixing shaft 52, the fixing shaft 52 passes through the fixing hole 363 and extends into the rectangular groove 361, the end of the fixing shaft 52 located inside the rectangular groove 361 is fixedly connected to a rectangular block 53 that fits into the rectangular groove 361; the outer wall of the rectangular block 53 is provided with a multi-directional inwardly recessed telescopic groove 533, the telescopic groove 533 and the limiting hole 362 are aligned. The telescopic block 531 is movably connected inside the telescopic groove 533. One end of the telescopic block 531 located on the inner wall of the telescopic groove 533 is connected to a telescopic spring 532. The other end of the telescopic spring 532 is connected to the inner wall of the telescopic groove 533. The other end of the telescopic block 531 extends through the limiting hole 362 into the positioning groove 42. The outer wall of the knob 51 is provided with a plurality of inwardly recessed toothed grooves 511. The toothed grooves 511 engage with the locking teeth 122. The knob 51 is engaged in the inner cavity 124 through the cooperation of the toothed grooves 511 and the locking teeth 122.During the installation of the take-up and release roller 2, first pull the handle 35. The handle 35 drives the connecting shaft 33, which in turn drives the slider 31 to move inside the tension groove 21. The movement of the slider 31 stretches the tension spring 32, facilitating the insertion of the limiting shaft 36 into the limiting hole 362. This allows the knob 51 to extend into the inner cavity 124 and connect with the locking teeth 122 through the toothed groove 511, facilitating the engagement of the knob 51 with the output end of the drive motor 123. Furthermore, as the limiting shaft 36 extends into the through hole 41, the telescopic block 531 engages with the through hole... When the inner wall of the telescopic block 531 contacts the telescopic block 532, the telescopic spring 532 retracts into the telescopic groove 533 under the influence of force. When the limiting shaft 36 moves into the positioning groove 42, the limiting hole 362 communicates with the positioning groove 42. When the telescopic block 531 is not under the influence of force, the telescopic spring 532 rebounds, causing the telescopic block 531 to pass through the limiting hole 362 and extend into the positioning groove 42, thus limiting and fixing the limiting shaft 36. This allows the take-up and untake-up rollers 2 to be installed between the mounting ears 4. The drive motor 123 drives the take-up and untake-up rollers 2 to rotate, realizing the take-up and untake-up.

[0031] Working principle of Example 1:

[0032] In use, the drive motor 123 operates, driving the knob 51. The knob 51 drives the limiting shaft 36 via the rectangular block 53. The limiting shaft 36 drives the connecting shaft 33. The connecting shaft 33 engages with the rectangularly arranged stretching groove 21 via the slider 31, thereby driving the take-up and unwind roller 2 to rotate, realizing take-up and unwind. When it is necessary to replace the take-up and unwind roller 2, simply hold the handle 35 and move it away from the mounting ear 4. This causes the limiting shaft 36 to extend into the through hole 41, making the telescopic block 531 contact the inner wall of the positioning groove 42. Under the influence of the force, the telescopic block 531 causes the telescopic spring 532 to retract into the telescopic groove 533, making it easier for the limiting shaft 36 to extend into the through hole 41. Thus, the handle 35 can easily drive the limiting shaft 36 away from the through hole 41. During the process of the limiting shaft 36 moving away, it drives the knob 51 away from the inner cavity 124, thereby realizing the disassembly of the take-up and unwind roller 2 and facilitating its replacement.
