Abstract
The utility model relates to a vernier caliper capable of magnifying display, which comprises a main scale and a vernier. According to the vernier caliper, an object to be measured is clamped at a proper position, the centimeter value with an integral number is read, then an auxiliary scale is fixed on the right side of a vernier through two pin columns, and a sliding bar is pushed to slide; the sliding bar is limited by an inclined sliding chute while the sliding bar slides vertically, and simultaneously the sliding bar slides towards the end part of the other side of the vernier, a pointer is driven to rotate while the sliding bar slides; when a flat plate props against the end part of the other side of the vernier, the sliding bar is limited, the pointer finishes the rotation and points a certain scale on a dial scale; since the length value of the vernier is an integral, the moving distance of the flat plate is the difference between the millimeter value of the object to be measured and 1; the vertically sliding distance of the sliding bar is larger than the transversely sliding distance; the millimeter value of the object to be measured is amplified once, and then amplified again according to the diameter multiple of a rotating shaft and the dial scale; and an operator can conveniently read out the scale value after the centimeters, and the measurement precision is determined by the marking precision of the dial scale.
