Abstract: A high-load linear actuator includes a driving mechanism, a worm shaft, a worm wheel assembly, a lead screw, a telescopic pipe and an outer pipe. The driving mechanism includes a base and a motor. The base has a supporting portion and an accommodating portion. The motor is fixed to the supporting portion. The worm shaft extends from the motor into the supporting portion. The worm wheel assembly includes a worm wheel and two bearings for supporting the worm wheel in the accommodating portion. The worm wheel is engaged with the worm shaft. The lead screw is disposed through the worm wheel and driven by the motor for rotation. The telescopic pipe slips on the lead screw to be threadedly connected therewith. The outer pipe slips on the telescopic pipe. The rotation of the lead screw drives the telescopic pipe to linearly extend or retract relative to the outer pipe.

Abstract: An electric linear actuator has a guide screw and a telescopic tube. A safety mechanism for the linear actuator includes a nut, a nut sheath, a sleeve, and a torsion spring. The nut connects the guide screw. The nut sheath is fixed on one side of the nut and is provided with a plurality of bumps. One end of the sleeve is put around the nut sheath and the other end thereof is connected to the telescopic tube. The sleeve is provided with a plurality of rabbets corresponding to the bumps. The torsion spring is disposed around the nut sheath and the sleeve. When the guide screw is rotated, the nut sheath is engaged with the sleeve by embedding the bumps into the rabbets. When the sleeve stops, the bumps and the rabbets depart from engagement to make the nut sheath and the nut freely rotate against the sleeve.
