[0012] Beneficial effects

[0013] When the hole opened in advance by the utility model is too large, the control handle is turned to drive the control worm to rotate, and then the two transmission shafts on the same side are rotated in opposite directions through a series of transmissions, and the rotating frame drives the support plate to move through the connecting rotating plate, so that the support plate contacts the inner wall of the hole, so that the metering box body is always in the center position of the hole, and the force on all sides of the metering box body is uniform, which reduces the stress concentration caused by position offset or tilt, enhances the stability of the overall structure, improves the installation accuracy of the metering box body, effectively improves the practicality of the metering box, and is more convenient to use.
