Integrated needle gauge

Abstract

The invention discloses an integrated needle gauge, comprising: a handle, a first needle bar and a second needle bar, the upper end of the handle is provided with a first internal thread, and the lower end outer wall of the first needle bar is provided with a The first external thread matched with the first internal thread, the upper end surface of the first needle bar is provided with a first groove, the inner wall of the first groove is provided with a second internal thread, the first The outer wall of the lower end of the second needle bar is provided with a second external thread, the second external thread is matched with the second internal thread, and the upper end surface of the second needle bar is provided with a second groove. The inner wall of the second groove is provided with a third internal thread. Through the above method, the integrated needle gauge of the present invention connects the needle rods of different specifications through the threaded connection of the upper and lower needle rods, so that the needle rods of different specifications are fixedly connected together in sequence, which is more convenient to use, takes up less space when stored, and is installed and disassembled through threads. The combination will not cause the loss of the needle bar, and the use effect is better.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to an integrated needle gauge. Background technique [0002] Needle gauges are suitable for the measurement of hole diameter, hole distance, and internal thread diameter in mechanical and electronic processing, especially for the measurement of bending groove width and mold size. The existing needle gauges are placed in a toolbox, and each size of the needle gauge All the gauges need to be placed one by one, which takes up too much space and is not convenient enough to use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an integrated needle gauge which takes up less space and has good use effect. [0004] In order to solve the above technical problems, the present invention provides an integrated needle gauge, comprising: a handle, a first needle bar and a second needle bar, the upper end of the handle is provided w...
