有you機ji械xie千qian斤jin頂ding和he液ye壓ya千qian斤jin頂ding等deng幾ji種zhong，原yuan理li各ge有you不bu同tong從cong原yuan理li上shang來lai說shuo，液ye壓ya傳chuan動dong所suo基ji於yu的de最zui基ji本ben的de原yuan理li就jiu是shi帕pa斯si卡ka原yuan理li，就jiu是shi說shuo，液ye體ti各ge處chu的de壓ya強qiang是shi一yi致zhi的de，這zhe樣yang
，在zai平ping衡heng的de係xi統tong中zhong，比bi較jiao小xiao的de活huo塞sai上shang麵mian施shi加jia的de壓ya力li比bi較jiao小xiao
，而er大da的de活huo塞sai上shang施shi加jia的de壓ya力li也ye比bi較jiao大da
，這zhe樣yang能neng夠gou保bao持chi液ye體ti的de靜jing止zhi。所suo以yi通tong過guo液ye體ti的de傳chuan遞di
，可ke以yi得de到dao不bu同tong端duan上shang的de不bu同tong的de壓ya力li，這zhe樣yang就jiu可ke以yi達da到dao一yi個ge變bian換huan的de目mu的de。我wo們men所suo常chang見jian到dao的de液ye壓ya千qian斤jin頂ding就jiu是shi利li用yong了le這zhe個ge原yuan理li來lai達da到dao力li的de傳chuan遞di。螺luo旋xuan千qian斤jin頂ding機ji械xie原yuan理li
，以yi往wang複fu扳ban動dong手shou柄bing，拔ba爪zhao即ji推tui動dong棘ji輪lun間jian隙xi回hui轉zhuan，小xiao傘san齒chi輪lun帶dai動dong大da傘san齒chi輪lun、使舉重螺杆旋轉
，從而使升降套筒獲得起升或下降，而達到起重拉力的功能。但不如液壓千斤頂簡易。
