Problems solved by technology

Therefore, when it is desired to stamp complex patterns or thick paper, in addition to the substantial increase in the amount of pressing force required for stamping the paper, the torque T is also greatly increased simultaneously, causing the connecting plate 113 of the base 11 to be easily deformed, which in turn leads to punching. Damage to holer 1

Abstract

A double-lever type stamping device comprises a base, a stamping die, an elastic obliquely-pressing unit, a first lever piece and a second lever piece. The base comprises a bottom die, a bearing piece, a first pin joint portion and a second pin joint portion. A stamping cutter die is penetratingly arranged in a through hole and positioned between the first pin joint portion and the second pin joint portion, and the stamping cutter die is tangent to the bottom die. The elastic obliquely-pressing unit is used for obliquely pressing the stamping cutter die to the direction away from the bottom die. The first lever piece comprises a first pivot portion, a first force applying portion and a first force resisting portion, the first pivot portion, the first force applying portion and the first force resisting portion are rotatably pivoted to the first pin joint portion, and the first force resisting portion butts against the top wall of the stamping cutter die. The second lever piece comprise a second pivot portion, a second force applying portion and a second force resisting portion, the second pivot portion, the second force applying portion and the second force resisting portion are rotatably pivoted to the second pivot joint portion, and the second force resisting portion butts against the first force applying portion.

Description

technical field [0001] The invention relates to a punching device, in particular to a double-lever punching device for punching out preset patterns or holes or watermark patterns on paper. Background technique [0002] Such as figure 1 As shown, the base 11 of the existing molding hole puncher 1 includes a base plate 111, a support plate 112 spaced above the base plate 111, and a connecting plate 113 connected between the base plate 111 and the support plate 112. The base plate 111 , the supporting plate 112 and the connecting plate 113 jointly define a space 114 for accommodating paper, and the bottom plate 111 forms a perforation 115 communicating with the space 114 . The stamping die 12 is disposed in a through hole 116 of the support plate 112 corresponding to the position of the through hole 115 . A plurality of compression springs 13 (only one of which is shown in the figure) have upper and lower opposite ends respectively abutted between the stamping die 12 and the ...
