[0009] The present invention will be described in detail below with reference to the accompanying drawings.
[0010] figure 1 It is a schematic diagram of the structure of the vernier caliper of the present invention. Aiming at the deficiencies of the existing vernier calipers, the present invention makes great efforts in the selection of the material of the vernier calipers, and selects a 6Cr16 material with high carbon content and high Cr content, which is quenched by high frequency. The hardness can reach 58HRC stably. However, due to the high price of this material, considering the economy of the finished product, the main ruler is divided into two parts: ruler body 1 and ruler head 2. The ruler body 1 part is made of 4Cr13 material with slightly lower hardness and lower price. The head 2 is made of 6Cr16 material with high hardness, the ruler body 1 and the ruler head 2 are fixedly connected by butt welding, and the vernier 3 is made of 6Cr16 material as a whole. The ve...
