Abstract

The invention discloses a measuring instrument for the diameter of a lever-type deep hole. The measuring instrument comprises a movable measuring head, an equal armed lever, a long tube, a dial indicator, a handle, an elastic device and a fixed measuring head, wherein the long tube is fixedly arranged in the handle, and the equal armed lever is fixedly arranged in the long tube; the lower-end measuring head of the dial indicator penetrates through the handle and the long tube to prop against the upper right end face of the equal armed lever, and the movable measuring head is fixedly arranged on the long tube and props against the upper left end face of the equal armed lever; the fixed measuring head is fixedly arranged on the long tube and is axially symmetric with the movable measuring head, and the elastic device is fixedly arranged in the long tube close to the movable measuring head; and the two ends of the elastic device respectively prop against the inner wall of the long tube and the low right end face of the equal armed lever. Through the method, the diameter of the deep hole can be accurately measured by the measuring instrument provided by the invention; and the measuring instrument has the advantages of high measuring precision, good versatility, convenience and quickness in measuring, and simplicity and practicality.
