Claims (1)

[Claims for Utility Model Registration] 1. A first detection lever which is mounted on the test piece by elastic force while holding the test piece between its tips; In an extensometer, the extensometer is equipped with a second detection lever which is mounted on the test piece by an elastic force with its tip portions sandwiched between the two; and a transducer which is mounted between the first and second detection levers and detects the relative displacement between them. a first support member having a base fixed to the tip of the first detection lever and a free end extending toward the second detection lever; a base fixed to the rear end of the second detection lever and having a free end; a second support whose end extends toward the first detection lever; a first leaf spring installed between the base of the first support and the free end of the second support to elastically connect the two; member; the above-mentioned second
a second plate spring member installed between the base of the support and the free end of the first support to elastically connect the two; installed between the first and second detection levers to maintain a gap between them; An extensometer characterized in that it is equipped with a gauge length gauge to determine the gauge length. 2. The first support body includes a first support rod fixed to the tip of the first detection lever so as to cross the same, and a first support rod that projects from both ends of the first support rod toward the second detection lever. the second support rod is fixed to the rear end of the second detection lever so as to cross it, and the second support rod is fixed to the rear end of the second detection lever, and a pair of second pillars, each protruding toward the first detection lever;
The second leaf spring member is comprised of a pair of leaf springs that are respectively attached parallel to each other between the lower end of the support and the free ends of the pair of second support supports.
A request for registration of a utility model characterized by comprising a pair of leaf springs installed parallel to each other between the lower ends of the pair of second columns and the free ends of the pair of first columns. The extensometer described in item 1.
