[0010] Preferably, the shape of the guide slide plate close to the measuring claw is arc-shaped, which can guide the wire so that it can be smoothly inserted into the inner side of the measuring claw.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the digital wire diameter measuring instrument based on photoelectric encoder uses a pull-rope photoelectric encoder as a displacement measuring device through the mutual cooperation between measuring claws, guide slides, fastening devices, control components, display panels, photoelectric encoders, encoder pull ropes and guide components. The wire diameter can be measured by measuring the displacement distance of the measuring claws. When the line is energized, the operator can measure the wire diameter of the line on the ground, which will not only not affect the normal power supply, but also improve the work safety of the construction workers.
