Abstract: A detecting gauge with high accuracy mainly comprises a machine table, a detecting set, a clamping apparatus, a detecting apparatus, and a sliding apparatus. Particularly, the sliding apparatus includes a sliding rail disposed on a machine table and a sliding base slidably disposed on said sliding rail. A sliding groove is disposed on both sides of the sliding rail, an embedding portion is formed on the sliding base for matching the sliding groove, and a plurality of rollers are embedded on a surface of said embedding portion which is in contact with said sliding groove. By matching the embedding portion with the sliding groove, the sliding base can be slid and moved precisely and smoothly on the sliding rail, and a target to be detected can be stably held by the clamping apparatus, whereby the detecting apparatus can obtain the measurement with high accuracy.

Abstract: An AC/DC air pump used for filling air into car tire, the housing of the air pump accomodates a driving motor with radiative fan, by applying a large gear driven by motor, and the large gear is gearing the link eccentrically to drive the piston of air cylinder for engaging in reciprocating motion so as to provide high or low pressure air-filling effect.
