Technical Field

[0001] The utility model relates to the technical field of triangular paper card punchers, in particular to a card puncher for triangular papers of insect specimens. Background Art

[0002] Insect specimens usually need to be fixed in a specimen box in a specific posture, and triangular papers can provide stable support for the bodies of insects. Especially for some insects with soft or slender bodies, triangular papers can help them maintain their natural forms, prevent deformation during preservation, and make the insect specimens more beautiful and tidy.

[0003] Currently, triangular papers are produced by cutting, but the specifications of triangular papers cannot be unified during cutting, and the specimen production lacks beauty. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a card puncher for triangular papers of insect specimens.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A card puncher for triangular papers of insect specimens includes a base, a punching base plate, a support structure, a pressing structure and a punching head. A punching base plate is arranged at the middle position on the upper surface of the base. The base and the punching base plate are movably connected through the support structure and the pressing structure. The support structure is a spring limit support structure. A punching head is arranged at the position corresponding to the punching base plate at the bottom of the pressing structure. A corresponding mold slot is arranged on the punching base plate corresponding to the bottom of the punching head. The punching head and the mold slot have the same shape.

[0007] The support structure includes a support rod, a spring and a pressing support rod. The support rod is arranged on the base on both sides of the punching base plate. The pressing support rod is arranged in the middle of the punching base plate. Springs are sleeved on both the support rod and the pressing support rod.

[0008] The pressing structure includes a connecting tabletop, a card holder, a pressing force-receiving plate, a rotary connecting seat, and an arc-shaped pressing block. A card holder is provided above the corresponding punching base plate. The punching head is fixedly arranged on the card holder. A horizontally crossed connecting tabletop is arranged in the middle of the upper surface of the card holder. Pressing force-receiving plates are arranged at both ends of the upper surface of the card holder. Limiting cylinders are arranged at positions corresponding to the support rods at both ends of the connecting tabletop and are penetrated. The support rods pass through the limiting cylinders, and the bottom of the limiting cylinders contacts the springs sleeved on the support rods. A through hole is arranged at a position corresponding to the pressing support rod in the middle of the card holder and the connecting tabletop. The bottom of the card holder contacts the spring sleeved on the pressing support rod. The top end of the pressing support rod passes through the through hole of the connecting tabletop and is fixedly connected to the bottom of the rotary connecting seat. The arc-shaped pressing block is movably connected to the rotary connecting seat through a rotating shaft.

[0009] A limiting rod is arranged on the side base of the support structure, and the height of the limiting rod is lower than the bottom of the connecting tabletop, which plays a limiting role when the pressing structure is pressed.

[0010] A pressing handle is arranged on the arc-shaped pressing block. The pressing handle is arranged on the opposite surface of the rotary connecting seat. When the arc-shaped pressing block is pressed through the pressing handle, the force application point is on the pressing force-receiving plate. When pressing, the punching head of the card holder under the pressing force-receiving plate is pressed downward. An insect triangular paper sheet to be punched is placed between the punching head and the mold card slot for punching.

[0011] Mold card slots are arranged at both ends of the punching base plate. Punching heads corresponding to the mold card slots are arranged at the bottoms of both ends of the card holder. The mold card slot is a triangular card slot or a pentagonal card slot of an isosceles triangle plus a quadrilateral rectangle.

[0012] The inner diameter of the limiting cylinder is larger than the diameter of the support rod, and the diameter of the through hole on the connecting tabletop is larger than the diameter of the pressing support rod, so that the connecting tabletop and the card holder can move up and down on the support rod and the pressing support rod when pressing.

[0013] The beneficial effects of the present utility model are as follows: The structure is simple, the operation is convenient, double-sided flexible punching can be carried out according to requirements, the specifications are unified, the operability is strong, the efficiency is higher than that of paper cutting, and it can be used for cardboards with different hardnesses.
