Long-pipe taper thread measurement device, taper plug gauge clamp and taper ring gauge clamp

The present invention discloses a long-pipe taper thread measurement device, a taper plug gauge clamp and a taper ring gauge clamp. The measurement device of the long-pipe tape thread comprises a support platform and a measurement mechanism, and also comprises a first support clamp, a second support clamp, a first taper sleeve clamp and a second taper sleeve clamp. A standard is installed on the first taper sleeve clamp and the second tape sleeve clamp, the first taper sleeve clamp is installed on an outer taper thread, and the second taper sleeve clamp is installed on an inner taper thread to allow the standard to fix with the outer taper sleeve thread and the inner taper sleeve thread; and the first support clamp and the second support clamp are installed on the support platform for measurement, and the location of the outer taper thread and the inner taper thread are completed at one time to avoid the installation location error caused by installing the standard at first and then installing the long taper
