CTC size measuring instrument

The utility model discloses a CTC dimension measuring instrument which comprises a support, a clamping mechanism, a pressurizing mechanism and a measuring mechanism. The clamping mechanism comprises a first clamping part and a second clamping part; the pressurizing mechanism comprises a pressure propelling part and a control part, the pressure propelling part is connected with the second clamping part, and the control part is used for adjusting the thrust of the pressure propelling part; the measuring mechanism comprises a pressure measuring assembly and a distance measuring assembly, the pressure measuring assembly is connected with the first clamping part, and the distance measuring assembly is used for measuring the distance between the first clamping part and the second clamping part. According to the utility model, the clamping mechanism, the pressurizing mechanism and the measuring mechanism are arranged on the support, so that the pressurizing mechanism can pressurize the transposed conductor clamped i
