High-precision control device for embedded part of small proton accelerator treatment bed

The utility model relates to a small proton accelerator treatment couch embedded part high-precision control device, which relates to the technical field of medical instrument installation, and comprises an embedded part body, a precision control mechanism, a preassembling hole, a glue filling groove and a fixing mechanism, the embedded part has the beneficial effects that by arranging the precision control mechanism, when the embedded part body is hoisted and installed through a crane, the bottom end of the positioning rod in the precision control mechanism serves as a calibration rod, and the calibration rod is used for calibrating the embedded part body; when the positioning rod corresponds to a ground marking area, namely, the positioning rod corresponds to six edge points of an embedded part body cross section drawing which is drawn on the ground in advance, the embedded part body can be lifted to a designated position by vertically lifting the embedded part body, so that the mounting precision of the em
