Abstract
The utility model discloses a leading screw gap eliminating device. The device comprises a slide block. One end of the slide block is provided with four holes. A leading screw is arranged in a leading screw hole. One end of the leading screw is provided with screw threads. The leading screw is matched with a leading screw nut in the slide block. The side wall of the leading screw net is fixedly equipped with a screw rod. The screw rod is sleeved with a compression spring. The two ends of the compression spring are respectively propped against the inner walls of the leading screw nut and the slide block. The leading screw gap eliminating device is precise in matching and prevents looseness caused by gaps generated in the interior of the leading screw.
