The utility model provides a mini-size pay-off device with a telescopic rotary plate and relates to a pay-off device. Currently, a prior pay-off device is large in size, high in weight and high in price and is suitable for leads of a single specification. The mini-size pay-off device with the telescopic rotary plate includes a pedestal, a stand shaft, a guide support, a rotary plate, a hand plate arranged above the rotary plate and a plurality of 7-shaped limiting supports arranged uniformly on a circle. The middle part of the guide support is provided with a wire via hole. The limiting supports are connected to the rotary plate perpendicularly in a dismountable manner. The rotary plate is provided with a plurality of waist-shaped grooves. The limit supports can move along the waist-shaped grooves in a radial direction, so that radial size can be adjusted for fitting wire plates of different specifications. The rotary plate includes a plurality of rotary strips distributed in a radial manner. Each of the rotary strips is provided with a lengthening strip capable of moving on the rotary strip for changing the size of the rotary plate. The lengthening strips are fixed on the rotary strips through screws. By adopting the technical scheme, the mini-size pay-off device with the telescopic rotary plate is small in size, low in weight, simple in structure, convenient to operate and carry and high in working efficiency. When the mini-size pay-off device with the telescopic rotary plate is required to fit a large wire plate, the lengthening strips can be extended on the rotary strips, so that application range of the mini-size pay-off device with the telescopic rotary plate is enlarged.
