Claims

[Scope of utility model registration request]

Support members are attached to the left and right positions of the upper surface of the instrument stand, and a connecting portion of the operating member is pivotally connected to the support members so as to be tiltable downward against a spring, and a guide provided on the side plate of the support member is provided. In a two-hole punch, a support pin penetrating the punch blade is vertically movably engaged in the hole, and both ends of the support pin are connected to the connecting portion of the operating member. An engagement hole is formed, and the support pin is slidable in the axial direction, and at one end thereof, when the support pin slides from the backward movement position to the forward movement position, the engagement hole is formed. When the support pin moves forward from the backward movement position, one side of the punching blade is abutting portions that come into contact with are provided respectively, and
A locking mechanism characterized in that a stop piece is provided facing the abutting portion and abutting on the other side of the punching blade when the support pin slides from the forward position to the forward position.
