Abstract:
A release mechanism incorporated linear actuator includes an actuator body and a release mechanism connected between a retractable tube set and a coupling. An adapter socket connected to the retractable tube set, a locating socket movably coupled to the adapter socket and connected to the coupling, a brake spring mounted around the adapter socket, a tightening sleeve sleeved onto the locating socket and the brake spring and connected to the locating socket, and a rotary knob attached onto the tightening sleeve. The brake spring is disposed in friction engagement with a surface of the tightening sleeve, having one end piece positioned in the adapter socket and an opposite end piece positioned in the rotary knob. When the rotary knob is rotated to move the opposite end piece, the brake spring is forced to reduce diameter and to wrap about adapter socket, releasing friction engagement between brake spring and tightening sleeve.

Claim (Index 1):
A release mechanism incorporated linear actuator, comprising:\n an actuator body comprising a holder block, a gear set mounted in said holder block, a power drive adapted for rotating said gear set, a transmission mechanism, comprising a lead screw meshed with said gear set, a retractable tube set linearly retractably coupled to said lead screw outside said holder block and a coupling connected to an outer end of said retractable inner tube outside said holder block and axially movable with said retractable inner tube relative to said lead screw; and a release mechanism coupled between said retractable tube set and said coupling, said release mechanism comprising an adapter socket connected to said retractable tube set, a locating socket connected to said coupling and movable coupled to said adapter socket, a brake spring mounted around said adapter socket, said brake spring comprising positioning means, a tightening sleeve connected to said locating socket and attached onto said locating socket and said brake spring and a rotary knob attached onto said tightening sleeve, said positioning means of said brake spring comprising a first end piece and a second end piece respectively extended from two opposite end thereof in different directions, said first end piece being positioned in said adapter, said second end piece being extended out of said tightening sleeve and positioned in said rotary knob, said brake spring being peripherally disposed in friction engagement with an inner surface of said tightening sleeve; and wherein when rotating said rotary knob to move said second end piece of said positioning means of said brake spring in one direction, said brake spring is forced to reduce the diameter thereof and to wrap about said adapter socket, releasing friction engagement between said brake spring and said tightening sleeve.
