Auxiliary device for reels, and reel including the same

A reel auxiliary device, comprising:

• a shell;
• a locking mechanism;
• a decelerating mechanism;
• and
• a transmission part;
• wherein a first side of the shell is provided with a first groove, and a second side of the shell is provided with a second groove;
• a first cover is provided at an opening of the first groove, and a second cover is provided at an opening of the second groove;
• and the first cover is connected with the first side of the shell, and the second cover is connected with the second side of the shell;
• the locking mechanism is arranged in the first groove, and is configured to control locking of a reel;
• the decelerating mechanism is arranged in the second groove, and is configured to reduce a rotating speed of the reel;
• the transmission part is arranged on a side of the first cover away from the first groove;
• the shell, the locking mechanism, the decelerating mechanism, and the transmission part are connected through a connecting part;
• and the shell, the locking mechanism, the decelerating mechanism, the transmission part and the connecting part are arranged coaxially;
• and
• in a case that the transmission part drives the connecting part, the locking mechanism and the decelerating mechanism to rotate in a forward direction, the locking mechanism is configured to alternately lock and unlock the connecting part, and the decelerating mechanism is configured to limit a rotating speed of the connecting part;
• and in a case that the transmission part drives the connecting part, the locking mechanism and the decelerating mechanism to rotate in a reverse direction, the decelerating mechanism is configured to limit the rotating speed of the connecting part.
