Abstract: A support device with differential mechanism transmission includes a base, a transmission device and a support mechanism. When the ring gear of the differential mechanism of the transmission device drives the first planetary gear assembly of the transmission device to rotate, the first planetary gear assembly cooperates with the central gear and the second planetary gear assembly of the transmission device to determine the sequence of unilateral transmission of the first lead screw and the second lead screw of the transmission device to drive the supporting legs of the support mechanism to expand outward or retract inward. In turn, it achieves the purpose of stable support, and has the effects of simple structure, miniaturization and cost reduction.

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.

Abstract: An electric push bar assembly includes an electric push bar including a retractable tube and a connector, and a release mechanism including a connection socket connected to the retractable tube, a fixed socket connected to the connector, a clutch socket axially slidably coupled to the connection socket and having a plurality of engagement tooth blocks respectively engaged with respective engagement teeth of the fixed socket and a rotary operating member mounted around the fixed socket and operable to disengage the engagement tooth blocks of the clutch socket from the engagement teeth of the fixed socket for allowing adjustment of the retractable tube manually.

Abstract: A dual-screw linear actuator includes a power drive unit including a gear set mounted in a holder frame thereof and a driver for rotating the gear set, a transmission mechanism including a sleeve coupled to and rotatable by the gear set, a tubular linkage rod mounted in and rotatable by the sleeve and having a first threaded connection portion and a second threaded connection portion respectively located at two opposite ends thereof, a first lead screw threaded into the first threaded connection portion and affixed to the holder frame for guiding movement of the tubular linkage rod forwardly/backwardly relative to the first lead screw upon rotation of the tubular linkage rod and a second lead screw threaded into the second threaded connection portion and movable forwardly/backwardly relative to the tubular linkage rod upon rotation of the tubular linkage rod.
