Device for improving paying-off speed and precision of slope component measured by total station

The utility model belongs to the field of surveying and setting-out construction of constructional engineering, and solves the problems that the position of a prism is inconvenient to adjust in the measurement process of an existing tripod, and a prism vertical rod on an inclined plane is inaccurate in positioning, so that measurement deviation is easily caused. The device comprises a measuring seat and a drawing seat which are arranged in parallel, the drawing seat can be drawn and locked in a sliding mode relative to the measuring seat, a sliding seat is arranged in the measuring seat, and a cross rod and a longitudinal rod which are crossed are arranged on the sliding seat in a sliding mode. A group of opposite transverse sliding grooves and a group of opposite longitudinal sliding grooves are formed in the inner wall of the measuring seat, a telescopic front supporting leg is arranged in the middle of the front end of the drawing seat, telescopic rear supporting legs are arranged on the two sides of the r
