A first input shaft A301 and a first output shaft 302 are rotatably connected to the first housing 304. Both the first driving member 305 and the first driven member 306 are disc-shaped structures. The first driving member 305 has a first guide hole along its axis, and a first guide block protrudes from the inner wall of the first guide hole. The outer circumference of the first input shaft A301 has a first guide groove corresponding to the first guide block along its axial direction. The driving member is slidably fitted onto the first input shaft A301 through the first guide hole, and the first guide block is slidably inserted into the first guide groove, allowing the first driving member 305 to move axially along the first input shaft A301. A first positioning disc is also fixedly mounted on the first input shaft, with a gap between the first positioning disc and the first driving member 305. The first elastic member 307 is a compression spring. A compression spring is fitted onto the first input shaft A301 and positioned between the first positioning plate and the first driving member 305. The compression spring allows the first driving member 305 to slide towards the first output shaft 302. The first driven member 306 is fixedly connected to the first output shaft 302. The end face of the first driving member 305 facing the first driven member 306 is provided with a plurality of first drive posts 308.

The second input shaft is also fixedly fitted with a second positioning disc, which has a gap with the second driving member 504. The second elastic member 506 uses a pressing... A compression spring is fitted onto the second input shaft 501 and positioned between the second positioning plate and the second driving member 504. The compression spring allows the second driving member 504 to slide towards the second output shaft 502. The second driven member 505 is fixedly connected to the second output shaft 502. The end face of the second driving member 504 facing the second driven member 505 is provided with multiple second drive posts. The second drive posts are cylindrical structures and are evenly distributed on the same two circumferences with the axis of the second input shaft 501 as the center line. The second driven member 505 is provided with a second drive hole corresponding to the second drive post. The second drive hole is an arc-shaped groove, and the arc length of the second drive hole is greater than the diameter of the second drive post. When the second drive post is inserted into the second drive hole, the second driving member 504 and the second driven member 505 are connected to form an integral structure.

The second drive member 504 rolls towards the end face of the second driven member 505 when the second drive member 504 is in contact with the second separation part 516. When the second rocker arm 508 is in the second separation part 516, the rocker arm is supported by the outer arc surface, so that the second drive member 504 cannot be displaced towards the second driven member 505 due to the elastic force of the second elastic member 506.

[0055] Specifically, such as Figure 1 As shown, the cable reel also includes a pin mechanism 8, which is disposed between the frame 1 and the winding reel 4. The pin mechanism 8 is used to position the winding reel 4 on the frame 1. The pin mechanism 8 includes a pin and a bracket. The bracket is connected to the frame 1, and the pin is slidably inserted into the bracket. The winding reel 4 has a socket for inserting the pin. When the pin is inserted into the socket, the winding reel 4 is positioned on the frame 1.
