本虎鉗原理是采用自行研發之往復式之空壓馬達（結構），以氣壓連續推動油路方式，來達成自動化，且不需三點組合來過濾水氣，其特性為全國所僅有，甚至越國內外任何品牌。
高夾持力
空壓源8kg/cm2 之低壓源，即可達4000kgf之高夾持力，而夾持力從0-4000kgf可借由調壓器自由調整設定。
Super high gripping force
Only need 8kg/cm2 of low air pressure source to achieve 4000kgf of super high gripping force.and this gripping force can be adjusted with in 0-4000kgf by using a pressure regulator.
自動尋找高空壓源
當銅鋁類產品輕加工或鑄鐵類毛坯重切削時，用調壓器設定至所需壓力，也不會因空壓源在低點而失壓，而且有自動補壓及穩壓之功能，以確保工件之夾持。
Find the highest air pressure point automatically
When processing copper,aluminum or heavy machining raw cast iron workpiece,the pressure regulator can be set at a desired pressure without losing pressure,besides,the gripping force can be kept to clamp the workpiece securely by auto compensating and pressure stabilizing functions
大夾持安全距離
開關速度只需1.5秒，手自動雙夾結構，自動調整并同時夾持5mm以內兩個大小不同之工件。
The biggest safety clamping range
The shifting speed is only 1.5 second.the double vise mechanism can be adjusted automatically and can simultaneously clamp two different workpieces in less than 5mm of size.
高材質
虎鉗本體材質采用高延展性之石墨鑄鐵（FCD60）一體成型設計，兩側滑軌經硬化熱處理（HRC50)，確保高精度，高耐磨，高抗張力。
Super rigid material
The body of the vice is integrally made of high tensile graphite casting iron(FCD 60)and is harden by heat treatment(HRC 50)at its two slide way,thereby ensuring high precision,high durability and high tensile.
內藏角固下壓結構
內藏角固下壓半圓球可產生角固下鎖之力可消除虎口板上浮和工作傾斜。
Submersed angle fixed pressed down structure
Submersed angle pressed structure in a semi-sphere shape to produce an angle lock power,thus preventing the cutting plate from movement.
