Abstract
Official abstract text for this publication.
A linear actuator ( 1 ) includes an electrical driving mechanism ( 10 ), a lead screw ( 20 ), an outer tube ( 30 ), a telescopic tube ( 40 ) and an arm driven mechanism ( 50 ). The arm driven mechanism ( 50 ) comprises an arm ( 51 ), a driving nut ( 52 ), a telescopic sleeve ( 53 ), a first washer ( 54 ), a nut-tube ( 55 ) and a second washer ( 56 ). The arm ( 51 ) is provided with a handle ( 511 ) and a sleeve ( 512 ), and the sleeve ( 512 ) links with the lead screw ( 20 ). An outer peripheral of the telescopic sleeve ( 53 ) provided with a plural of screws for screwing with the telescopic tube ( 40 ). The nut-tube ( 55 ) links with the driving nut ( 52 ) for moving together. When the handle ( 511 ) rotates, the linear actuator ( 1 ) can be operated.
