Abstract
The invention discloses a dragging mechanism. A connecting shaft is arranged on the end face of a rotation stopping part. The dragging mechanism also comprises a rotating shaft sleeve with a U-shaped structure. A connecting arm is fixedly arranged at the open end of the rotating shaft sleeve. The connecting shaft penetrates through a U-shaped groove of the rotating shaft sleeve. When the rotating shaft sleeve rotates around the connecting shaft until the sidewall of the rotating shaft sleeve is approximately parallel to the end face of the rotation stopping part, the U-shaped groove of the rotating shaft sleeve has a section of path for the rotating shaft sleeve to slide down along the connecting shaft in a direction from the bottom of the U-shaped groove to the open end. In a non-working state, the rotating shaft sleeve can rotate around the connecting shaft until the sidewall of the rotating shaft sleeve is approximately parallel to the end face of the rotation stopping part, and the U-shaped groove of the rotating shaft sleeve can slide down along the connecting shaft under the action of own gravity of the rotating shaft sleeve and the own gravity of the connecting arm. Parts, positioned at the lower end and the upper end of the connecting shaft, on the rotating shaft sleeve can be matched with the end face of the rotation stopping part to prevent the rotation of the rotating shaft sleeve around the connecting shaft, so that the space occupation of the long connecting arm is avoided.
