Abstract

The invention relates to the technical field of a measuring tool, and particularly to a hole center locator. The hole center locator comprises a pull rod, an expansion sleeve, a gasket and a locking device. The pull rod is provided with an axle hole in a through manner. The pull rod comprises a first end and a second end. The second end is provided with a spacing projection. The expansion sleeve sleeves the pull rod. One end of the expansion sleeve abuts against the spacing projection. The gasket sleeves the pull rod and is arranged at one side, which is far from the spacing projection, of theexpansion sleeve. The locking device is connected with the pull rod. When the locking device moves in a direction of approaching the spacing projection, the gasket can be driven to push the expansionsleeve in the direction of approaching to the spacing projection, so that the expansion sleeve deforms in a direction along a central axis, thereby realizing expansion of the expansion sleeve in theaxial direction. The invention provides the hole center locator for settling a technical problem of incapability of accurately locating the hole center by the hole center locator in prior art.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a hole center locator. Background technique [0002] On equipment or components with holes, it is extremely important to determine the centerline of the hole. For example, when it is necessary to punch holes around the hole, mark lines or measure the hole distance based on the centerline of the hole, it is necessary to first determine the center of the hole The position of the line. [0003] In the prior art, the hole center locator for determining the position of the center line of the hole is inconvenient to use and cannot accurately locate the hole center. [0004] Therefore, the present application provides a new hole center locator for the above problems. Contents of the invention [0005] The object of the present invention is to provide a hole center locator to solve the technical problem that the hole center locator in the prior art cannot accurately locate th...
