弾条受けを受けている押込式硬度試験機。[Scope of Claim for Utility Model Registration] The load shaft has an indenter attached to the lower free end, and the load shaft includes a first bullet receiver and a bullet receiver support. The load shaft is arranged so as to be movable up and down within a fixed shaft having an annular portion that receives the first bullet receiver from the lower side thereof, A shaft mantle to which a load is applied by the load arm is disposed around a portion of the load shaft above the position where the first bullet receiver is attached, and the shaft mantle and the first bullet receiver are arranged. A first reference load bullet is inserted between the bullet receiver and the bullet receiver so that the first bullet receiver is received by the ring portion of the fixed shaft mantle, and on the bullet receiver support, A second bullet receiver is disposed between the second bullet receiver and the ring portion of the fixed shaft mantle, such that the second bullet receiver is received by the bullet receiver support. , a second standard load bullet is inserted, and a ring portion is formed on the fixed shaft mantle from the outside thereof;
and a lowered position in which the ring portion does not receive the second bullet receiver, and a lowered position in which the ring portion receives the second bullet receiver from below against the second bullet receiver. A reference load selection cylinder is attached that selectively takes a lifting position, and the bullet receiving support receives the second bullet receiving in the lifting position of the standard load selection cylinder, In the lifting position of the reference load selection cylinder, the bullet receiver support does not receive the second bullet receiver, and the reference load selection cylinder receives the second bullet receiver. A push-in hardness tester.
