[0026] The limiting groove 11 is matched with a limiting block 12 on the circumferential wall of the rotating drum 6 .

[0027] A slide groove 13 is provided above the bottom plate 1 , and a guide rail 14 for sliding the second bracket 4 is provided in the slide groove 13 . A second spring 15 is sleeved on the surface of the guide rail 14 , and one end of the spring abuts against the back surface of the first bracket 3 and the other end abuts against one end of the slide groove 13 .

[0028] A buffer pad is provided at one end of the slide groove 13 to prevent the first bracket 3 from colliding when the spring is reset.

[0029] The outer wall of the second bracket 4 is provided with a motor 16 and the inner wall is movably provided with a fixing frame 17. The output end of the motor 16 passes through the second bracket 4 and is rotatably connected to the second bracket 4. The motor 16 drives the fixing frame 17 to drive the take-up rod 5 to rotate. The fixing frame 17 is provided with a mounting groove and cooperates with the two ends of the take-up rod 5 and is connected by bolts. The bolt is rotated to rotate the first threaded hole and the inner wall of the second threaded hole, and then the bolt is taken out, and then the take-up rod 58 is pulled to slide in the second mounting groove, so as to achieve the effect of removing the take-up rod 5.

[0030] Embodiment 1: The clamping structure includes a rotating drum 6 arranged on the side of the first bracket 3 and a wire drum 7 connected to the rotating drum 6, pressing blocks 8 are arranged on the circumferential walls at both ends of the wire drum 7, and pressing grooves for pressing the pressing blocks 8 are arranged below the pressing blocks 8, spring grooves are opened at both ends of the wire drum 7 and a first spring 9 is installed in the spring grooves, and a limiting clamp 10 cooperating with the pressing block 8 is arranged on the rotating drum 6, and a limiting groove 11 for the limiting clamp 10 to move downward is arranged below the limiting clamp 10, so that the wire drum 7 forms a clamping fit with the first bracket 3 to prevent jumping during rotation and collision with the installation groove caused by jumping and causing loud noise.
