CN2488658Y - Pinhole plotter with actuating unit in regulating crank type - Google Patents

Abstract

The utility model discloses a pinhole plotter with actuating unit in regulating crank type, comprising a handle, a lever, an upper knife plate, a base frame and a spring, wherein, when force acts on the handle, the handle performs clockwise revolution, at the same time, the knife head of the upper knife plate starts linear motion by transmission of the structures such as the lever and so on. Therefore, the utility model has such characteristics of simple structure and low cost as well as saving force in operation.

Description

Connecting lever actuating unit puncher

Use relates to the hand puncher, more specifically is meant a kind of connecting lever actuating unit puncher, belongs to the office appliance class.

The hand puncher of seeing in the market, handle motion mostly adopt around center of circle gyration, and another is a push type rectilinear motion from top to bottom, construct different, complex structure, the resistance of motion is bigger

The purpose of this utility model provides a kind of connecting lever actuating unit puncher, and this punching function overcomes the shortcoming that above-mentioned traditional puncher exists, and has advantage simple in structure, that the resistance of motion is little.

In order to achieve the above object, the utility model includes handle, connecting lever, goes up knife plate, underframe and extension spring, handle is joining three holes that distributing on the face of two connecting levers, connecting lever, the hole of following stomidium and underframe is handed over and is propped up and core of projection, the hole of connecting lever upper end hole and handle is handed over and is propped up, can do circumnutation, the connecting lever interstitial hole fastening an axle core, two elongated slots are arranged on the last knife plate, hold stomidium and underframe hole under the connecting lever in the elongated slot and hand over the axle core of a projection, on the elongated slot side one horizontal elliptical aperture is arranged, hold the axle core on the connecting lever interstitial hole in the hole, spring is connected on handle and the underframe.

Do the time spent when handle is stressed, handle is handed on the fulcrum to underframe by corresponding two the hole force transmission of connecting lever, be subjected to the restriction of underframe, connecting lever is joining handle and is doing the clockwise direction revolution, like this connecting lever interstitial hole fastening the axle core, the elliptical aperture of knife plate in the compressing moves downward so go up knife plate, and the shrinkage pool that cutter head rushes on the underframe is finished the punching action.Long slot bore and elliptical aperture have got out of the way the movement position of upper and lower motion of last knife plate and connecting lever interstitial hole axle core on the last knife plate.

After finishing the punching action, active force disappears on the handle, and extension spring makes handle, connecting lever, upper slitter sheet reset.

Because the elongated slot (more than two) on the last knife plate is close running fit with its core, changed the gyration mode of connecting lever, having guaranteed all has packing ring or baffle plate to block before and after the downward rectilinear motion of last knife plate, elongated slot, makes that knife plate is unlikely rocks with laughter, and has guaranteed moving both vertically of last knife plate fore-and-aft direction.

This shows, the utlity model has simple in structure, with low cost, the little characteristics of the resistance of motion.

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to figure 1, Fig. 2, Fig. 3, the utility model comprises handle 1, connecting lever 2, goes up knife plate 3, underframe 4, extension spring 5.Handle 1 three holes that distributing on two connecting levers 2, the connecting lever face, hand over and axle core of projection in the hole of following stomidium and underframe 4, connecting lever 2 can be done circumnutation, the hole of connecting lever 2 upper end holes and handle 1 is handed over and is propped up, the connecting lever interstitial hole fastening an axle core; There is the hole that holds stomidium and underframe 4 under the connecting lever in two elongated slots, the elongated slot to hand over the axle core of a projection on the last knife plate 3, on elongated slot antero posterior axis core, be equipped with and stop packing ring or baffle plate, on the elongated slot side one horizontal elliptical aperture is arranged, hold the axle core on the connecting lever interstitial hole in the hole, can do micro-transverse movement, spring 5 is connected on handle and the underframe 4.

With reference to figure 4, Fig. 5, Fig. 6, do the time spent when handle is stressed, handle by corresponding two holes of connecting lever with force transmission to the underframe fulcrum, be subjected to the restriction of underframe 4, connecting lever is joining handle and is doing revolution clockwise, so the fastening axle core of the interstitial hole of connecting lever 2, the elliptical aperture of knife plate in the compressing, knife plate is moved downward, and cutter head rushes at underframe 4 upper concave holes, and a plurality of cutter heads are arranged on the last knife plate.

Claims (2)

1. connecting lever actuating unit puncher, include handle, connecting lever, go up knife plate, underframe and spring, it is characterized in that: handle is joining three holes that distributing on two connecting levers, the connecting lever face, the hole of following stomidium and underframe is handed over and is propped up and core of projection, the hole of connecting lever upper end hole and handle is handed over and is propped up, the connecting lever interstitial hole fastening an axle core, there is the hole that holds stomidium and underframe under the connecting lever in two elongated slots, the elongated slot to hand over the axle core of a projection on the last knife plate, on the elongated slot side one horizontal elliptical aperture is arranged, hold the axle core on the connecting lever interstitial hole in the hole, spring is connected on handle and the underframe.

2. puncher according to claim 1 is characterized in that on the protruding axis core of knife plate elongated slot front and back packing ring or baffle plate being housed.
