ものである。Conventional technology Conventionally, at the rear of the left and right positions on the upper surface, a ridge with a height that allows the intervention of the hole to be drilled is provided, and at the front thereof, a drilling hole is provided, through which a rod-shaped drilling blade described later is inserted. The rear part is fixed to the right and left ridges to form a paper intervention part between the front part and the top surface of the table, and a guide hole is formed in the bottom of the front part. A pair of left and right support members each having a support hole with a support hole for supporting the upper part of the perforating blade body in the front and rear direction, and a pair of left and right support members each having an upwardly U-shaped cross section, and the front portions of the left and right side plates of this support member. A pair of left and right rod-shaped drilling blades are supported by support pins that pass through arc-shaped guide holes provided in the guide hole, and move up and down between the support hole, the guide hole, and the drilling hole, and a downward-pointing control is provided at the front left and right positions. an operating member formed with a letter-shaped connecting portion, the connecting portion being tiltably attached to the front portions of the left and right supporting members by pivot pins, and both ends of the supporting pins being connected to the connecting portion; A two-hole perforator is known, which is comprised of a pair of left and right springs that are interposed between the connecting portion of the operating member and the left and right support members, respectively, and that elastically bias the operating member in the open direction at all times. When storing the perforator in a drawer or the like, or transporting the perforator,
A locking mechanism is also known in which the operating member is locked in the perforation state tilted against the biasing force of a spring to configure the perforator into a flat shape for convenience when packing. The mechanism includes a support pin that extends in the axial direction and extends laterally through the connecting portion of the operating member, the guide hole provided in the front part of the side plate of the support member, and the punching blade, respectively, and allows one end of the support pin to slide in the axial direction. The lower end of the guide hole is provided with a large-diameter neck portion, and the lower end of the guide hole is formed with a large-diameter engagement hole that engages with the neck portion, so that the operating member resists the biasing force of the spring when not in use. In the drilling state where the support pin is tilted, the support pin is slid in the axial direction to engage the neck with the engagement hole, thereby preventing upward movement of the support pin and locking the operating member in the drilling state. It is of composition.
