An amphibious foldable treadmill includes: a main frame having at least a wheel rotatably mounted on a base of the main frame to be rolled on a ground floor or on a pool bottom, a tread belt device pivotally secured to the main frame and unfolded from the main frame to be laid on the floor or pool bottom for treading operation, and a hand rail device pivotally secured to the main frame and pivotally connected with the tread belt device, whereby upon folding of the hand rail device and the tread belt device to the main frame, the treadmill can be folded for convenient handling, moving, launching in a pool or landing on the ground floor from the pool for successfully serving as an amphibious treadmill.

The invention discloses a high-precision treadmill printing machine driven by double servo motors. The first servo motor installed on a first scraping and printing track beam and the second servo motor installed on a second scraping and printing track beam rotate to drive an output gear of the first servo motor and an output gear of the second servo motor to rotate and move back and forth in the rack direction, and scraping and printing devices can be positioned in the gray fabric length direction. A scraping and printing device main motor rotates, drives printing and scraping device synchronous belts to rotate through synchronous gears and transmission connection rods and finally drives the scraping and printing devices to move back and forth in the gray fabric width direction for scraping and printing. The first lifting servo motor and the second lifting servo motor drive a first lead screw movement block and a second lead screw movement block to move up and down through a first lead screw and a second lead screw and finally drive the right end of the first scraping and printing track beam and the right end of the second scraping and printing track beam to move up and down so that the scraping and printing devices can be driven to move up and down. The high-precision treadmill printing machine has the beneficial effects of being reasonable in structure, high in positioning precision, small in noise and capable of improving the printing quality.
