description The utility model belongs to the technical field of coal mine drilling equipment, and provides an orifice connector for a high-position drill site to solve the technical problems that coal cinder and gangue blocks at the lower portion of an orifice of the high-position drill site are gathered, slag return is not good, a slag discharging opening is prone to being blocked, then the orifice is blocked, and gas in a blocked hole cannot be effectively extracted. Connecting flanges are arranged at the ends of the connecting pipes, the connecting pipes at the two ends are connected with the in-hole reducer pipe and the deslagging pipeline respectively, a deslagging pipe and an extraction pipe are further arranged on the outer side of the cavity and connected with the deslagging pipeline and the negative pressure respectively, and the deslagging pipe and the extraction pipe are oppositely arranged on the two sides of the cavity. The device is simple in structure and convenient to use, the hole opening is provided wit
