Friction braking type rotating disc structure for coding machine

The utility model discloses a friction braking type rotating disc structure for a coding machine, which comprises a rotating disc body, the rotating disc body comprises a colored tape starting disc upper cover, a colored tape starting disc lower cover and a rotating shaft, the top of the rotating shaft is clamped and connected with the colored tape starting disc upper cover, and the bottom of the rotating shaft is clamped and connected with the colored tape starting disc lower cover. According to the friction braking type rotating disc structure for the coding machine, the nut is rotated to enable the rotating disc structure to move, the degree of extrusion to the main spring is changed, the rotating shaft is rotated, the rotating shaft is rotated, the rotating shaft is rotated, the rotating shaft is rotated, the rotating shaft is rotated, and the friction braking type rotating disc structure is convenient to operate. And through the action of the main force spring on the pressure bearing, the friction force
