Detailed ways

In order to further understand the features, technical means, and specific objectives and functions of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 2 and Fig. 3, the vertical measuring device of the utility model is used for measuring the inclination of precision products such as microscope supports, and described vertical measuring device comprises verticality measuring seat 10, dial indicator 20 and slide bar 30, and described The dial indicator 20 is clamped on the verticality measuring seat 10 and slides up and down; the verticality measuring seat 10 is provided with a guide groove 11, and the dial indicator 20 is clamped in the described guide groove 11 and moves along the The guide groove 11 slowly slides back and forth up and down; the dial indicator 20 includes a probe head 21, a watch body 22 and a clamping boss 23, the probe head 21 is arranged on the top of the watch body 22, and the clamping boss 23 Extending from the bottom end of the watch body 22, the clamping boss 23 is clamped in the guide groove 11; the slide bar 30 is fixedly arranged at one end of the probe head 21, and is connected with the probe head 21 vertical settings.
